8. Fasten the conduit to the ash base with the clamps
provided.
Floor Protection:
The striped area indicates the minimum required floor protec-
tion area if the boiler is going to be placed on a combustible
floor. It requires 40” X 55”(US) or 42” X 55”(CAN) of non
combustible floor protection as shown. 16”(US) or 18”(CAN)
of the floor protection must be in front of the firebox door
as shown. Floor protection must be a minimum of 26 gauge
sheet metal. Floor protection must also be provided under any
horizontal run of vent pipe equal to the outside diameter of the
venting plus 2” to each side.
Design:
The first thing that needs to be done is deciding where and
how the boiler will be installed.
Things that need to be taken into consideration are the
intended use of the boiler for example, is the boiler going to
be used as your primary heating system or is it going to be
used as a secondary or backup heating system. If it is to be
used in conjunction with an existing oil or gas boiler system
will it be piped in parallel or in series? The answers to these
and other questions can be determined by talking to your
certified dealer or a qualified HVAC or plumbing contrac-
tor. This will ensure that the boiler is installed and piped to
accommodate your needs and expectations.
Example: 4” type “L” or “PL” vent pipe has an outside diam-
eter of 4-1/2” + 2” on each side equals a protected floor area
of 8-1/2” wide underneath the horizontal run.
Consideration must be given to the venting as well as
electrical and clearance requirements. (Clearances must be
maintained to combustibles and also for service)
Make sure fans are not used in the fuel storage area, unless
they are installed so as not to create a negative pressure in the
room where the solid fuel burning appliance is located.

Avoiding Smoke and Odors - Negative Pressure,
Shut-down and Electrical Power Failure.
To reduce the probability of reverse drafting dur-
ing shut-down conditions, Hearth & Home Tech-
nologies strongly recommends:
• Installing the pellet vent with a minimum vertical
run of 5 feet. Preferably terminating above the roof
line.
To reduce the probability of back-drafting or burn
back in the pellet boiler during a power failure,
it must be able to draft naturally without exhaust
blower operation. Negative pressure in the house will
resist this natural draft if not accounted for during in-
stallation. Heat rises in a house, and leaks out at upper
levels. This air must be replaced with air from outside
the dwelling, which normally flows into lower levels.
Vents and chimneys into basements and lower levels
can become the conduit for return air and reverse un-
der these conditions.
Hearth & Home Technologies strongly recommends
the use of outside air in all pellet boiler installa-
tions, especially those on lower level and main floor
locations. Per national building codes, consideration
must be given to combustion air supply to all combus-
tion appliances. Failure to supply adequate combustion
air for all appliance demands may lead to back-draft-
ing of those and other appliances within the home.
• Installing the outside air intake at least four feet
below the vent termination.
To prevent soot damage to exterior walls, and to pre-
vent re-entry of soot or ash into the house:
• Maintain specified clearances to windows, doors
and air inlets, including air conditioners.
• Vents should not be placed below ventilated soffits.
Run the vent above the roof.
• Avoid venting into alcove locations.
• Vents should not terminate under overhangs, decks
or onto covered porches.
• Maintain minimum clearance of 12” from the vent
termination to the exterior wall. Extending this dis-
tance may be required if visual accumulation occurs.

Venting
venting
Venting
Use 4” pellet vent pipe only.
A combustion blower is used to extract the combustion
gases from the firebox. This creates a negative pressure in
the firebox and a positive pressure in the venting system
as shown in Fig. 4. The longer the vent pipe and more
elbows used in the system, the greater the flow resistance.
Because of these facts we recommend using as few elbows
as possible and 30 feet or less of vent pipe. The maximum
horizontal run should not exceed 18 feet.
4” Type “L” or
“PL” Vent pipe
Be sure to use wall and ceiling pass through fittings
(which are approved for pellet vent pipe ) when going
through combustible materials. Be sure to use a starting
collar to attach the venting system to the stove. The start-
ing collar must be sealed to the stove flue collar with
high temp silicone caulking or aluminum tape, and
screwed into the stove flue collar at least three (3) places.
Fig. 5
This is the minimum venting configuration.
The minimum vent configuration is a 90o or Tee on
a starter collar and a 24” length horizontal through an
exterior wall. A cap on the end should direct the flue
gasses down and away from the structure. See Fig. 5.
The maximum horizontal length is 18 feet. The
minimum termination height above the exterior grade
is 18”. The maximum total length of any configuration
is 30 feet*.
* ( see venting graph on page 9 for exceptions )
NOTE: Cleanout Tee’s should always be used on the
transitions to horizontal pipe to allow easy access for
cleaning.
+
-
The venting graph allows for one(1) 90 deg. or Tee
fitting in any configuration.
If more 90’s, T’s, or 45’s are needed, the total length
must be adjusted to allow for the added restriction.
Up to four (4) additional 90’s, Tee’s, or equivalent 45’s
can be added as long as the overall length is adjusted in
accordance with the values listed below.
Fig. 4
Vent Pipe
4” pellet vent pipe (also known as “PL” vent) is con-
structed of two layers with air space between the layers.
This air space acts as an insulator and reduces the outside
surface temperature to allow a minimum clearance to
combustibles as low as 1 inch. In Canada the minimum
clearance to combustibles is 3 inches.
The sections of pipe lock together to form an air tight
seal in most cases; however, in some cases a perfect seal
is not achieved. For this reason and the fact that the boiler
operates with a positive vent pressure, we specify that all
joints within the structure should also be sealed with
silicone.
( See the venting graph on page 10.)
Each Vertical ---- 90 deg. or T subtract 2.5 feet
Each Vertical ---- 45 deg.
Each Horizontal - 90 deg. or T subtract 5.0 feet
Each Horizontal - 45 deg. subtract 2.5 feet
subtract 1.5 feet
Any exterior venting (vent pipe exposed to outside
ambient temperatures) should be kept to a minimum,
due to potential condensation problems.
This is especially important in high humidity cold
weather climates, such as maritime areas, lake shores,
and low river valleys.
NOTE:Use only 4” diameter approved PELLET
venting system. Be sure to inspect and clean exhaust
venting system frequently.

Creosote - Formation and Need for Removal - When wood is burned slowly, it produces tar and other organic vapors,
which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue
of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an
extremely hot fire. The pellet vent pipe should be inspected at least twice monthly during the heating season to determine
if a creosote buildup has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
Guidance on minimizing creosote formation and the need for periodic creosote removal: The chimney should be
inspected during the heating season to determine if a creosote build-up has occurred. If a significant layer of creosote has
accumulated (3mm or more) it should be removed to reduce the risk of a chimney fire.

Outside Air
To install outside air, use 2 3/4” I.D.galvanized
steel flex pipe, part # 2-00-08544 ( 12’6” length) or part
# 2-00-08545 ( 25’length) See Fig. 6. There is a break-
away hole on the rear panel which must be removed
before connecting the flex pipe. See Fig. 7.
When the appliance is side wall vented: The air
intake is best located on the same exterior wall as the
exhaust vent outlet, and located lower on the wall than
the vent outlet.
When the appliance is roof vented: The air intake
is best located on the exterior wall oriented toward the
prevailing wind direction during the heating season.
Never terminate the outside air above the vent pipe
outlet. The maximum length of this pipe is 20 feet. Inlet
cover part number 1-10-09542 should be used to keep
birds, rodents etc.out of the inlet pipe. See Fig.6.
NOTE: The inlet cover should not be placed in an
area where drifting of snow or ice will build up, block-
ing the intake air supply.

Over heat Safety zone
OverHeat Safety Zone (Dump Zone): STRONGLY RECOMMENDED in all installations.
When the pellet boiler is operating at High burn, and all demand from the heating system stops, the control
will reduce the feed rate and shut down completely as necessary. This may take several minutes, and the remain-
ing heat may cause the water temperature to continue to rise. If the temperature gets too high, the OVERHEAT
SAFETY ZONE light on the control (see page 23) will illuminate, and the DARK BLUE circuit in the junction box
is energized(see wiring diagram). This circuit will flow 120V to operate a circulator pump installed to flow to the
overheat dump zone established in the original installation plan. If opening a zone valve is the chosen method of
dumping the excess heat, a voltage reduction relay will most likely be needed. If the water temperature continues
to rise to the risk of boiling point, the feed system will stop and the boiler will shut-down. A manual reset will then
be required to operate the boiler. Without a dump zone in place, the excess temperature will build pressure to the
point of opening the relief valve, or with the atmospheric conversion it will allow the water to boil and over-flow
the atmospheric tank. Both scenarios may create water damage and/or slip hazard.
The boiling temperature of water varies at different altitudes and atmospheric pressures. Therefore, at eleva-
tions above 3000 feet, and when using the atmospheric conversion, circuit board dipswitch #6 must be in the “ON”
position.

Draft Test Procedure
After the venting is completed, the firebox low draft
will need to be checked and possibly adjusted. After
removing the 3/8” bolt from the draft hole shown in Fig.
9, insert the draft meter tube. The appliance doors and
hopper lid must be latched during this test. (It is recom-
mended that the draft meter have a scale of 0 to 1” WC.)
Turn the feed adjuster to “Test”. this will start the
combustion blower and allow you to check and record
the High Draft ______ - IWC date _______ The
maximum draft must not exceed -.85” W.C. Some form
of vent restrictor may be needed. (There is no control
board adjustment for the High Draft)
Firebox Door
Draft Bolt Location
Air Wash Slot

After the first 60 seconds the “Test” mode lowers the
combustion blower voltage to the Low Burn voltage.
During this lowered voltage cycle the Low Burn Draft
must be checked and adjusted if necessary. The recom-
mended low draft setting should be between -.25 & -.35
IWC. Depending on the amount of vertical rise, it may
not be possible to get a low draft reading in this range.
In this case, a maximum low draft of -.55 is acceptable.
The adjustment screw is through the small hole to the
right of the Igniter Light. See Fig. 10. Adjusted Low
Draft is __________ -IWC.
Viewing Window

Fuel Specifications
Fuel and Fuel Storage
Performance
Pellet fuel quality can fluctuate from manufacturer to
manufacturer, and even from bag to bag.
Hearth & Home Technologies recommends using only
fuel that is certified by the Pellet Fuels Institute (PFI).
•
•
•
Higher ash content requires more frequent mainte-
nance.
“Premium” grade pellets will produce the highest
heat output.
Burning pellets longer than 1-1/2 inches (38mm)
can cause inconsistent feeding and/or ignition.
Fuel Material
•
•
Made from sawdust and/or other wood by-products
Source material typically determines ash content
We recommend that you buy fuel in multi-ton lots
whenever possible. However, we do recommend try-
ing different brands prior to purchasing multi-ton lots,
to ensure your satisfaction.
Higher Ash Content Material
•
•
•
Hardwoods with high mineral content
Bark and leaves as source material
“Standard” grade pellets, corn and other biomass
CAUTION! Tested and approved for use with wood
pellets ONLY. Burning of any other fuel will void your
warranty.
Lower Ash Content Material
•
•
•
Softwood; pine, fir, etc.
Materials with lower mineral content
“Premium” grade pellets
When changing from “Premium” grade pellets to a
“Standard” or “Economy” grade fuel, the FEED AD-
JUSTER will likely need adjusted to a lower setting.
When under maximum demand, ensure there is no
unburned fuel being pushed into the ash pan.
CAUTION! Do not burn fuel that contains an additive;
(such as soybean oil)
•
•
May cause hopper fire
Damage to product may result
Storage
•
Wood pellets should be left in their original sealed
bag until ready to use, to prevent moisture.
Do not store fuel within the specified clearance ar-
eas, or in a location that will interfere with routine
cleaning and maintenance procedures.
Read the list of ingredients on the packaging. If you are
buying wood pellets, the only ingredient listed should be
wood fiber or sawdust.
•
Clinkers
Minerals and other non-combustible materials, like sand,
will turn into a hard glass-like substance when heated.
Trees from different areas will vary in mineral content.
For this reason, some fuels will produce more clinkers
than others.
Moisture
CAuTION
Always burn dry fuel. Burning fuel with high moisture
content takes energy to dry and tends to cool the appli-
ance thus, robbing heat from your home. Damp pellet
fuel could turn back into sawdust which does not flow
properly through the feed system.
Tested and approved for use with wood pellets
ONLY. Burning of any other fuel will void your
warranty.
Size
NOTICE
•
Pellets are either 1/4 inch or 5/16 inch (6-8mm) in
diameter
Hearth & Home Technologies is not responsible for
stove performance or extra maintenance required
as a result of using fuel with higher ash or mineral
content.
•
•
Length should be no more than 1-1/2 inches (38mm)
Pellet length can vary from lot to lot from the same

Operation
Setting The Boiler Temperature
Without the Outdoor Air Temperature Sensor
Installed
To set the maximum boiler water temperature, sim-
ply turn the Max. Temp. water temperature dial to the
desired setting. The control and the boiler will then
perform to achieve and maintain the set temperature.
The Min. Temp. Knob is the boiler water tempera-
ture minimum, or the lowest temperature the water
will go before the unit re-starts. Turning the knob fully
counter-clockwise is the “OFF” position, while turn-
ing the knob clockwise, past the 140 degree marking,
is the “ON” position..
With The Outdoor Air Temp - Sensor Installed
Maximum boiler temp setting is as described above.
The MIN. TEMP. knob in addition to being the
mode setting (on or off) now also has the function of
setting the minimum boiler water temperature. This
would be the lowest boiler water temperature that you
want to have based on the following factors.
1.) Outdoor Air Temperature (OAT)
WATER TEMPERATURE
2.) Domestic Hot Water Use
a.) Hot Water Coil Option
b.) Indirect Hot Water Storage
3.) Overall Volume of the Heating System
MAX. TEMP.
Control Board Operation
MIN. TEMP.
The boiler is designed to withstand lower return water
temperatures however, extended return temperatures below
140 degrees F can cause condensation in the secondary
ash chamber area and also in the venting system, which
could cause damage in these areas.
Aquastat Sensor - This sensor is located in the aqua-
stat well on the top of the water jacket. This sensor
along with the outdoor air sensor is what the control
board uses to regulate the feed rate based on these two
observed conditions. (Boiler Temp. & Outdoor Air
Temperature)
NOTE:
Outdoor Air Temp. Sensor (OAT) - This sensor is
located outside the building (on the north side of the
house and out of direct sunlight). The Outdoor Air
Sensor is used to perform hot water reset based on out-
door air temperatures.
When the OAT sensor is installed, at 20° F. or below
(outside temperature), the boiler will operate at the
temperature set on the MAX. TEMP. knob. The boiler
water temperature will decrease by 1 degree F. for
every 1 degree F. in temperature rise (above 20°) of
the outdoor air.
If the system is run at the lower temperature settings, con-
ditions of the firebox, boiler tubes, secondary ash chamber
and venting should be monitored closely. If conditions show
excess condensation, the boiler water minimum tempera-
ture will need to be increased until condensation does not
occur. You should also consider some form of tempering of
the return water system. Discuss this with your plumber.

Operation
Starting A Fire Automatically
1. Turn Mode Selector to “OFF”.
This resets the control in addition to turning
it off.
2. Clean Burnpot with scraper, if necessary.
This is usually a weekly maintenance proce-
dure. Cleaning the burn pot with the scraper with
a small amount of new fuel in the bottom is not a
problem. First, scrape the ashes on the front of the
burn pot into the ash pan. Then scrape the hole grid
surface downward into the burn pot. When the stove
is ignited these scrapings will be pushed out by the
feeder.
The illustration at left shows the hopper swing plate
open for easy access to the burn pot. The burn pot
can also be reached through the firebox door.
NOTE: To minimize the amount of stress placed
on the hopper swing plate hinges, opening of the
hopper swing plate should be done with the least
amount of fuel in the hopper as possible.
Scrape burnpot to remove any carbon
build-up that may have occurred
3. Fill Hopper with pellets.
When filling the hopper check for excessive fines
in the bottom of the hopper. Fines are small pieces of
broken pellets (sawdust). Fines do not flow easily and
often build up on the hopper funnel bottom angles.
These fines can be pushed into the feeder opening
and then fill the hopper with pellets. As the system
works, they will be burned.

Operation
4. If Starting After an Empty Hopper, Turn Feed
Adjuster to “TEST” (for one 60 second cycle).
This will feed pellets into the auger tube and also
allow you to check the motors for operation. NOTE:
The auger motor will not operate with any of the
doors open.
5. Turn Feed Adjuster to #4.
If this is your first fire or you are trying differ-
ent pellets, set the feed adjuster to #4, This is an
average number for most pellets and may need to
be adjusted for your particular fuel. After you know
a feed rate setting that works well for your applica-
tion, use that setting.
NOTE: You know your feed rate is too high when:
The overheat safety feature is energized each time
the heating zone demand turns off during a high burn.
OR, If unburned or partially burned pellets are found
in the ash pan.(this may also be an indication of a
burn pot in need of scraping.)
6. Flip the Igniter Switch up into the “AUTO”
position.
7. Turn the MAX. TEMP. Dial on the control
board to the desired temperature. This setting must
always be at least 5° F. higher than the MIN. TEMP.
setting.

Operation
7. Open hopper swing plate as shown in Fig. 13 (See
“NOTE” on page 26.)
8. Turn the MIN. TEMP. Dial on the control board
to the desired Minimum temperature. This will start the
lighting process if the temperature at the aquastat sensor
is approximately 5° F. less than the set temperature on
the MAX TEMP. dial.
This is more than just an automatic ignition pellet
boiler. The automatic system will allow the fire size to
be adjusted to match the heating needs and even put the
fire out if necessary. If heat is needed after the fire is out,
the boiler will automatically re-ignite and adjust the fire
size to match the heating need.
Fig. 13
8. Fill burnpot with pellets as shown.
See Fig. 14. Only fill level with the front edge.
( ------- DO NOT OVERFILL ------- )
9. Fill hopper with pellets and remove ashes as
required.
Type of Fuel
Use pelletized wood only. The lower the ash content of
the pellets the less cleaning that will be needed of the
heat exchanger surfaces. The cleaner these surfaces are
kept, the more efficient the boiler will be.
NOTE: Do not burn garbage, gasoline, naphtha, engine
oil, or other inappropriate materials in this unit.
Store pellets in the manufacturer’s wrapping until
needed to prevent pellets from absorbing moisture.
Do not store fuel within the appliance installation
clearances, or within the space required for fueling,
ash removal, and other routine maintenance
operations.
Lighting A Fire Manually
Lighting the fire manually will not be necessary unless
the igniter system fails.
Follow steps 1 through 5 of the instructions for
automatic lighting.
6. Flip the Igniter Switch Down into the “MANUAL-
LIGHT” position. See Fig. 12.
Fig. 14
9. Have matches or other ignition source ready.
10. Turn Mode Selector to desired MIN TEMP setting.
This will start the combustion blower and allow the
ESP to control the fire in relation to the MAX TEMP
Dial setting. (The MAX TEMP dial setting must always
be set above the MIN TEMP setting) Once the fire is
well established the MAX TEMP dial can remain on
any temperature setting desired.
NOTE: When the Switch is set to Manual ignite position
the boiler will function as in auto ignite except the fire will
not be allowed to go out. It will only be allowed to go to a
minimum burn rate between the times the aquastat is calling
for heat. This rate is about 1.1 pound of fuel per hour. If used
in the Manual ignite mode, be sure there is an overheat dump
zone in place. Note that if the dump zone does not provide
sufficient cooling, and the water temperature continues rising,
the feed motor will be forced to shut off. Because the unit is
in Manual Ignite mode, it will not re-ignite when the water
temperature cools below the control settings.

Operation
11. Apply starting gel as shown in Fig.15
12. Light The Starting Gel With A Match.
Fig. 15
NOTE: Stirring the starting gel into the pellets usually
allows the fire to become established quicker.
13. Close The Doors
The fire will light and the control will adjust the fire
to the proper level according to the MAX TEMP dial
setting.
CAUTION: A vapor flash could occur if too much
time is allowed to pass before lighting the starting gel.
NOTICE: when burning the boiler in the
manual ignition mode, there must be an
overheat dump zone incorporated into the
plumbing system.
CAUTION: Care must be taken not to get starting gel
on your hands or clothing. Serious burns could occur
during the lighting process.
CAUTION: Never try to apply more starting gel to an
already burning fire, or a fire with smoldering pellets.
If heating demand stops during manual operation, the
control will take the unit to low burn. If no heat is used
during this time, the water temperature will continue to
rise. When the temperature gets too high, the feeder will
be turned off and the fire will go out. This will require a
manual re-start of the system. (see page 23 “7 Blinks”)
“NEVER USE GASOLINE, GASOLINE-TYPE
LANTERN FUEL, KEROSENE, CHARCOAL
LIGHTER FLUID, OR SIMILAR LIQUIDS TO
START OR “FRESHEN UP “ A FIRE IN THIS
APPLIANCE. KEEP ALL SUCH LIQUIDS WELL
AWAY FROM THE UNIT WHILE IN USE”.
Solid-fuel burning appliances need to be cleaned
frequently because soot, creosote, and ash may accu-
mulate. If you suspect a chimney/vent pipe fire do
the following:
1. Call the fire department.
2. Remove fuel from the burn pot using the burnpot
scraping tool to scrape the pellets into the ash pan.
3. Remove the ash pan from the unit and take outside.
Do not place ash pan on a combustible material.
4. Turn off circuit breaker at unit.
5. Do not use the unit until a qualified person has in-
spected your appliance and venting.

maintenance
Burnpot Cleaning:
The burnpot should be cleaned no less than once a week.
For best operation the burnpot should be cleaned every time
the hopper is filled with pellets. The fire does not have to be
out to scrape the burnpot although it is recommended the
boiler be on minimum burn at the time of cleaning.
Note: Scraping can be done while in operation if per-
formed through the firebox door opening. See Fig. 17
Use the flat end of the scraper provided to scrape down
over the holed surface of the burnpot grate. See Fig. 18. It
is not necessary to clean out the scrapings from this clean-
ing because they will be pushed out the next time the auger
operates.
Note: Make a special effort to scrape the bottom inside
corners of the burnpot where the auger tube enters the
burnpot. Carbon deposits can build up over time in this
area that may cause a restriction to the flow of pellets into
the burnpot.
Note: An old long shank screwdriver with the end sharp-
ened is an ideal aid in the removal of these deposits.
Scrape the burnpot to remove any carbon
deposits which may have formed.
Scraping can be done while the boiler
is in operation, accessed through the
firebox door opening.
Fig. 17
Fig. 18
Cleaning the Burnpot Air Chamber:
This area only needs to be cleaned twice a heating sea-
son, unless excessive buildup is noticed during scheduled
cleanings.
There is a cover on the front of the burnpot to gain access
to the air chamber. The cover is held into place by two thumb
screws. Loosen the thumb screws and remove the cover. See
Fig. 19. The air chamber can be cleaned of any ash that has
fallen through the holes during operation and cleaning.Also
at this time, remove the feeder assembly cover and remove
any fines that may have accumulated.
Cleanout cover

NOTE: ALWAYS REMEMBER TO CLOSE THE CLEA-
NOUT COVER AFTER CLEANING.
Fines area
Feeder Chamber (Fig. 20):
This chamber may get a buildup of fines from the feeder
mechanism movement. This area should be checked and
cleaned at least once a year.
To remove the feeder cover:
• Loosen the 5/16” wing nut.
• Slide the cover off of the threaded stud and lift upward.
• Inspect and clean the inner chamber if necessary. See Fig. 20.
• Reinstall the cover making certain it is centered on the
feeder body and hand-tighten the wing nut.

Disposal of Ashes
WARNING! RISK OF FIRE!
Ash, soot or creosote build-up may cause
overheating or fire.
Routine cleaning of heat exchangers and
venting is required.
Ashes should be placed in a steel container with a tight
fitting lid. The closed container of ashes should be moved
outdoors immediately and placed on a non-combustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If ashes are disposed
of by burial in soil or otherwise locally dispersed, they
should be retained in the closed container until all cinders
have thoroughly cooled. Other waste shall not be placed
in this container.
•
•
Ash Removal
It is recommended to remove the ashes when the boiler
is not in operation. This lessens the chances of coming in
contact with hot surfaces. Ashes can be removed while
in operation but, extra care must be taken.
Soot and Flyash: Formation and Need for
Removal
Open Ash Door
The products of combustion will contain small particles
of flyash. The flyash will collect in the exhaust venting
system and restrict the flow of the flue gases. Incomplete
combustion, such as occurs during startup, shutdown,
or incorrect operation of the room heater will lead to
some soot formation which will collect in the exhaust
venting system. The exhaust venting system should be
inspected at least twice monthly to determine if cleaning
is necessary. Pay particular attention to screening in the
vent cap. The screen, if present, will accumulate with
ashes rather quickly.
Lift the latch and open the door as shown in fig. 21.
NOTE: Keep hopper lid, hopper swing plate, firebox
door and ash pan door closed during operation and
maintain all seals in good condition.
Remove Ash Pan
Always wear gloves to remove ash pan. Grab the ash
pan by the finger hold and pull it out of the boiler. Lift
the ash pan by the finger hold and use it for carrying the
ash pan. Close the ash door before disposing the ashes.

Cleaning
-Open the ash door and remove the ash pan. Dispose
of any ash that has accumulated in the ash pan as well
as any fly ash from within the ash pan area.
-Remove the (4) thumbscrews on the secondary
ash chamber access plate and remove it to access the
secondary ash chamber. Remove all fly ash from this
area. This process should be done as needed.
This cleaning should be done after each ton of pellets
used. The frequency of this cleaning will be directly
related to the quality and the ash content of the pel-
lets being used. Keep in mind that the cleaner the heat
exchanger surface is kept, the higher the heat transfer
efficiency will be.
Due to it’s ease of restarting it is recommended that the
boiler be OFF and COOL before cleaning.
-Inspect all sealing gaskets to ensure a proper seal
and re-install all components removed for cleaning.
Start by actuating the (3) heat exchanger cleanout rods
by pulling and pushing these rods vigorously several
times. This action will remove any fly ash built up on the
heat exchanger tubes. This can also be done at any time
during the operation of the boiler to maintain higher ef-
ficiencies. Make sure that these rods are pushed in when
cleaning is completed.
CAUTION: Cleanout of the heat exchanger, flue
pipe, chimney, and combustion blower fan housing,
is especially important at the end of the heating
season to minimize corrosion during the summer
months, caused by accumulated ash.
Cleaning Steps
-Open the hopper swing plate to access burnpot and
also the firebox. With a wisp brush, wire brush, stiff
bristled paint brush or a soot vac, clean the firebox walls
and any fly ash that has accumulated on the ledges of the
burnpot, or burnpot opening.At this time you can scrape
and clean the burnpot and fines cleanout area.
-Open firebox door and vacuum ash from ledges and
ash deflector.You can also clean the firebox door viewing
glass using a typical glass cleaner and soft cloth.
NOTE: To minimize the amount of stress placed on
the hopper swing plate hinges, opening of the hopper
swing plate should be done with the least amount of
fuel in the hopper as possible.

Loosen the three (3) thumb screws about 4 turns each.
See Fig. 23. Hold the motor head with one hand and the
blower plate handle with the other hand. Pull outward
on the plate handle until the complete unit comes loose.
Now rotate the plate counter-clockwise about 1/8 turn.
This will allow the complete assembly to be removed
from the blower chamber.

Clean the blower fan blades and the blower plate
sealing overlap. See Fig. 24.
NOTE: Be careful not to bend the fan blades, this will
throw the fan blade out of balance or it may rub the inner
chamber, which may affect the performance of the boiler.
Any horizontal and vertical flue pipe directly above the unit
should be cleaned at this time
Exhaust Probe
Combustion
Blower Motor
NOTE: The horizontal flue pipe directly above the boiler
is the first place fly ash will settle, due to the slowing of flue
gas velocity through horizontal pipe. Cleaning of horizon-
tal venting pipes is very important to the efficiency of this
boiler.
Thumb Screws (3 Total)
Fig. 23
Clean the flue outlet throat as well as the inner chamber
of the flue tunnel (this is the hole that goes up into the
flue pipe). See Fig. 24.
NOTE: The exhaust probe sensing tip extends into
this same area. CARE MUST BE TAKEN NOT TO
DAMAGE THE ESP DURING CLEANING. Bending
of the ESP will make it difficult to remove if it should
become necessary. See Fig. 23.
Clean the boiler blower plate, sealing overlap. See Fig
24. Make sure there are no fly ash buildups that may
block the easy flow of flue gasses into the combustion
blower inlet hole. ( A flashlight may be necessary. )
Sealing Overlap
Cleaning the Tube Heat Exchangers:
5” Double
The heat exchanger tubes have external handles that
operate the cleaning mechanisms. See picture on page 32.
This cleaning should be done at least once a week,
although it can be done as often as desired. The cleaner
the heat exchangers are, the more efficient the boiler
will be. This cleaning can be done at any time and in
any mode of operation. During high fire periods, the
cleaning rods may stick due to heat related expansion.
Bladed Fan
Fig. 24
Combustion Blower Cleaning
Remove the combustion blower heat shield. There are
two latches that hold the shield in place (See Fig. 22). Flip
the latches up and pull the shield away from the boiler.
It can not be fully removed, it can only be moved down
over the wire until it hangs on the junction box.
CAUTION: Inspect flue pipes, flue pipe joints and
flue pipe seals regularly to ensure that smoke and
flue gases are not entering the home.

Troubleshooting
FEEdEr dOES NOT FEEd
SmOKE IS vISIblE COmINg OuT OF vENT
1. No pellets in hopper.
1. Air-fuel ratio is too rich.
2. Firebox draft may be too low for low draft pres-
sure switch in feeder circuit to operate. Check
for improperly closed doors, loose or missing
gasket on doors or hopper lid, or a faulty pres-
sure switch.
3. Feed motor will not run until the ESP
senses 170 deg. F. Maybe you did not put
enough pellets in the burn pot before lighting the
fire manually.
A. Feed rate too high.
B. Draft too low caused by a gasket leak.
lOw hEAT OuTPuT
1. Feed rate too low
2. Draft too low because of gasket leak.
3. Poor quality or damp pellets
4. Combination of 1 and 2.
4. Something is restricting flow in the hopper or
causing the slide plate to stick.
5. Feed motor has failed.
PArTIAllY burNEd PEllETS
1. Feed rate too high.
helpful hints
Cleaning burn Pot
whenever your boiler is not burning, take
the opportunity to scrape the burn pot to remove
carbon buildup. A vacuum cleaner is handy to
remove the residue. be sure the boiler is cold if
you use a vacuum.
2. Draft too low. (Check burn pot clean-out slide
and door gasket).
3. Burn pot or heat exchanger tubes may need
to be cleaned.
4. Combination of all the above.
5. #6 status blink: A 6 blink control board sta-
tus indication is caused by poor or incomplete
combustion. The Automatic Ignition circuit board
has the ability to track the combustion through
feed settings and ESP temperatures. when the
control board has calculated poor or incomplete
combustion, it will shut down the unit as a safety
feature. (Poor or incomplete combustion is a
contributer of creosote which may cause a chim-
ney fire)
A 6 blink status may be caused by several
things:
1. Blocked or partially blocked flue.
2. Blocked or partially blocked inlet air.
a. Backdraft damper on the inlet pipe may be
stuck closed.
Carbon buildup can be scraped loose with
the fire burning using the special tool provided
with your stove. Scrape the floor and sides of the
burn pot. The carbon will be pushed out by the
incoming fuel. Always wear gloves to do this.
removing Ashes
Ashes can be removed while in operation,
but extra care must be taken and always wear
gloves.
Maximum Feed Adjuster settings are not
needed in most cases. Operating in the normal
range (#4) is recommended when maximum heat
output is not required. The ESP prevents the
stove from being over-fired.
Keep the boiler free of dust and dirt.
b. If outside air is installed, the inlet cover may
be blocked.
3. The air chamber under the burnpot may be
filled with fines and small bits of ash.
4. The holes in the burnpot may be getting filled
with ash or carbon buildup.
Fuel
Pellet fuels are put into 3 categories in terms of
ash content. Premium at 1% or less, Standard at
3% or less and all others at 3% or more.
This unit is capable of burning all 3 categories
of pellets due to a patented feeder and burn pot
system.
It should be noted, however, that higher ash
content will require more frequent ash removal,
scraping of the burn pot, and may provide less
BTU’s per pound. Normally, standard and high ash
pellets cost less than premium pellets and can be
cost effective when burned in this boiler.
The moisture content must not exceed 8%.
Higher moisture will rob BTU’s and may not burn
properly.
5. Combustion blower fan blades may need
cleaned.
6. There is no fuel in the hopper.
SmOKE SmEll
Seal the vent pipe joints and connection to stove
with silicone.
FIrE hAS gONE OuT
1. No pellets in hopper.
2. Draft setting is too low.
3. Something is restricting fuel flow.
4. Feed motor or combustion blower has failed.
5. Power failure or blown fuse.

Atmospheric Conversion
Atmospheric Conversion: Item # 1-00-232200, provides automatic fill, and converts the heating
system plumbing from pressurized to a zero pressure system. Allows for installation into more
places where codes and standards restrict pressurized systems. Note that when using the atmo-
spheric conversion, air bleeders and check valves may actually allow air into the lines. Another
reason it is important to have a licensed Plumber involved in each phase of your installation.
when using the atmospheric conversion, the circuit board dipswitch #6 must
be in the “ON” position. This will lower the overheat temperature parameters
to prevent boiling of the water. Since altitude affects the boiling point, it is also
recommended to set #6 to “ON” at elevations above 3000 ft.
