pliance. Consult local code authorities.  
When installing this appliance at an elevation above 2000 ft,  
it may be necessary to decrease the input rating by chang-  
ing the existing burner orice to a smaller size. Input rate  
should be reduced by 4% for each 1000 ft above a 2000 ft  
elevation in the U.S.A., or 10% for elevations between 2000  
and 4500 ft in Canada. If the heating value of the gas has  
been reduced, these rules do not apply. To identify the prop-  
er orice size, check with the local gas utility.

A. Design and Installation Considerations  
Heatilator B-vent gas appliances are designed to operate  
with all exhaust gases expelled to the outside of the building,  
and combustion air pulled from the room.  
CAUTION  
Check building codes prior to installation.  
Installation MUST comply with local, regional,  
state and national codes and regulations.  
Consult insurance carrier, local building, fire  
ofcials or authorities having jurisdiction about  
restrictions, installation inspection, and permits.  
When planning an appliance installation, it’s necessary to  
determine the following information before installing:  
Where the appliance is to be installed. See Sections 3  
and 4.  
The vent system conguration to be used. See Sections  
5 and 6.  
Gas supply piping. See Sections 7 and 9.  
Electrical wiring. See Sections 7 and 10  
Framing and finishing details. See Sections 3, 6  
and 11.  
Whether optional accessories—devices such as a fan, wall  
switch, or remote control—are desired. See Section 16.  
WARNING  
Keep appliance dry.  
Mold or rust may cause  
odors.  
Water may damage controls.

To minimize the effects of negative air pressure, the follow-  
ing must be considered:  
B. Negative Pressure  
Install the outside air kit. Install the intake on the side of  
the house towards prevailing winds during the heating  
season.  
Ensure adequate outdoor air is supplied for combustion  
appliances and exhaust equipment.  
Ensure furnace and air conditioning return vents are not  
located in the immediate vicinity of the replace.  
Avoid installing the replace near doors, walkways or small  
isolated spaces.  
Recessed lighting should be a “sealed can” design; attic  
hatches weather stripped or sealed; attic mounted duct  
work and air handler joints and seams taped or sealed.  
Basement installations should be avoided due to stack  
effect. Stack effect creates negative pressure in lower  
levels. Hearth & Home Technologies recommends the  
use of direct vent replaces in basements.  
WARNING  
Asphyxiation Risk  
Negative pressure can cause spillage of  
combustion fumes and soot.  
Fire needs to draft properly for safe  
operation.  
Draft is the pressure difference needed to vent replaces  
successfully. Considerations for successful draft include:  
Preventing negative pressure.  
Location of replace and chimney.  
Negative Pressure  
Negative pressure results from the imbalance of air avail-  
able for the replace to operate properly. Causes for this  
imbalance include:  
Location of the replace and chimney will affect performance.  
As shown in Figure 2.1 the chimney should:  
Exhaust fans (kitchen, bath, etc.).  
Range hoods.  
Combustion air requirements for furnaces, water heaters  
and other combustion appliances.  
Clothes dryers.  
Location of return-air vents to furnace or air  
conditioning.  
Imbalances of the HVAC air handling system.  
Upper level air leaks (recessed lighting, attic hatch  
opening, duct leaks).  
Be installed through the warm airspace enclosed by the  
building envelope. This helps to produce more draft,  
especially during lighting and die-down of the re.  
Penetrate the highest part of the roof. This minimizes the  
effects of wind turbulence.  
Be located away from trees, adjacent structures, uneven  
roof lines and other obstructions.  
Offsets can restrict draft so their use should be minimized.  
Consider the replace location relative to oor and ceiling  
and attic joists.

B. Construct the Appliance Chase  
WARNING  
A chase is a vertical boxlike structure built to enclose the gas  
appliance and/or its vent system. Vertical vents that run on  
the outside of a building may be, but are not required to be,  
installed inside a chase.  
Fire Risk  
Construct chase to all clearance  
specications in manual.  
Locate and install appliance to all  
clearance specications in manual.  
Construction of the chase may vary with the type of build-  
ing. These instructions are not substitutes for the require-  
ments of local building codes. Local building codes MUST  
be checked.  
Chases should be constructed in the manner of all outside  
walls of the home to prevent cold air drafting problems. The  
chase should not break the outside building envelope in any  
manner.  
Walls, ceiling, base plate and cantilever oor of the chase  
should be insulated. Vapor and air inltration barriers should  
be installed in the chase as per regional codes for the rest of  
the home. Additionally, Hearth & Home Technologies recom-  
mends that the inside surfaces be sheet rocked and taped  
(or the use of an equivalent method) for maximum air tight-  
ness.  
To further prevent drafts gas line holes and other openings  
should be caulked with high temp caulk or stuffed with un-  
faced insulation. If the appliance is being installed on a ce-  
ment slab, we recommend that a layer of plywood be placed  
underneath to prevent conducting cold up into the room.

I. Air Shutter Setting  
This appliance has an adjustable air shutter (which controls  
the primary air) factory set for the minimum vertical vent run  
(see Figure 12.10). If your installation has more than the  
minimum required vertical vent length, adjustment of the air  
shutter may be necessary to obtain optimal ame appear-  
ance. This should be adjusted by a qualied installer at  
the time of installation.  
If the vent configuration is installed incorrectly, the  
vent may cause the ames inside the appliance to lift  
or “ghost,” which is a dangerous situation. Inspect the  
ames after installation to ensure proper performance. If  
the vent conguration is correct, yet the ames are lifting  
or ghosting, shut off the gas to the appliance and contact  
the dealer.  
Figure 12.10Air Shutter  
Your air shutter is provided at 1/8 in. open for natural  
gas, 3/8 in. open for propane (30 in./33 in. appliances),  
and full open for 36 in. and 42 in. propane appliances. In  
the event soot is accumulating in your appliance, the air  
shutter should be opened farther. This can be done by  
opening the control access panel and locating the two wing  
studs and two wing nuts attaching the valve assembly to  
the rebox. Remove the wing nuts and wing studs, slide  
the valve assembly to the left and lower. Rotate the valve  
assembly horizontally and remove from underneath the  
appliance. See Figure 12.11.  
Note: To avoid damage to the pilot assembly,

D. After the Appliance is Lit  
Initial Break-in Procedure  
CAUTION  
When you light the appliance, you may notice that it pro-  
duces heat which does have an associated odor or smell. If  
you feel this odor is excessive it may require the initial three  
to four hour continuous burn on high followed by a second  
burn up to 12 hours to fully drive off any odor from paint and  
lubricants used in the manufacturing process. Condensation  
of the glass is normal  
Prevent accidental appliance operation when not  
attended.  
Unplug or remove batteries from remote control if  
absent or if appliance will not be used for an extended  
period of time.  
Property damage possible from elevated  
temperatures.  
Note: This appliance should be run three to four hours  
on the initial start-up. Turn it off and let it cool completely.  
Remove and clean the glass. Replace the glass and run  
the appliance for an additional 12 hours. This will help cure  
the products used in the paint and logs.  
CAUTION  
Smoke and odors are released during initial  
operation.  
Open windows for air circulation.  
Leave room during initial operation.  
Smoke may set off smoke detectors.  
During this break-in period it is recommended that some  
windows in the house be opened for air circulation. This will  
help avoid setting off smoke detectors, and help eliminate  
any odors associated with the appliance’s initial burning.  
Smoke and odors may be irritating to sensitive  
individuals.

E. Frequently Asked Questions  
Issue  
Solutions  
Condensation on the glass  
This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will  
disappear.  
Blue ames  
This is a result of normal operation and the ames will begin to yellow as the appliance is allowed to burn for 20 to  
40 minutes.  
Odor from appliance  
Film on the glass  
When rst operated, this appliance may release an odor for the rst several hours. This is caused by the curing of  
the paint and the burning off of any oils remaining from manufacturing.  
This is a normal result of the curing process of the paint and logs. Glass should be cleaned within 3 to 4 hours of  
initial burning to remove deposits left by oils from the manufacturing process. A non-abrasive cleaner such as gas  
replace glass cleaner may be necessary. See your dealer.  
Metallic noise  
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to the sound produced  
by a furnace or heating duct. This noise does not affect the operation or longevity of the replace.  
Is it normal to see the pilot  
In an Intellire ignition system it is normal to see the pilot ame, but it should turn off when ON/OFF is turned off.

Troubleshooting  
14  
With proper installation, operation and maintenance your gas appliance will provide years of trouble-free service. If you do  
experience a problem, this troubleshooting guide will assist a qualied service person in the diagnosis of a problem and the  
corrective action to be taken. This troubleshooting guide can only be used by a qualied service technician.  
A. Standing Pilot Ignition System  
Symptom  
Possible Causes  
Corrective Actions  
1.  
After repeated triggering  
of the red or black piezo  
ignitor button, the spark  
ignitor will not light the  
pilot.  
A.  
B.  
Defective ignitor.  
Check the spark at the electrode and pilot. If there is no spark and the  
electrode wire is properly connected, replace the ignitor.  
Defective pilot or  
misaligned electrode  
(spark at electrode).  
Using a match, light the pilot. If the pilot lights, turn off the pilot and trigger  
the red or black piezo ignitor button again. If the pilot lights, an improper  
gas/air mixture caused the bad lighting and a longer purge period is  
recommended. If the pilot will not light, ensure the gap at the electrode and  
pilot is 1/8 in. to have a strong spark. If the gap is OK, replace the pilot.  
C.  
No gas or low gas  
pressure.  
Check the remote shut-off valves from the appliance. There is usually a  
valve near the gas main. There can be more than one valve between the  
appliance and the main.  
D.  
A.  
No LP in tank.  
Check the LP (propane) tank. You may be out of fuel.  
2.  
The pilot will not stay lit  
after carefully following  
the lighting instructions  
Defective thermocouple.  
Check that the pilot ame impinges on the thermocouple. Clean and/or  
adjust the pilot for maximum ame impingement.  
Ensure that the thermocouple connection at the gas valve is fully inserted  
and tight (hand tighten plus 1/4 turn).  
Disconnect the thermocouple from the valve, place one millivolt meter lead  
wire on the tip of the thermocouple and the other meter lead wire on the  
thermocouple copper lead. Start the pilot and hold the valve knob in. If the  
millivolt reading is less than 15mV, replace the thermocouple.  
B.  
A.  
Defective valve.  
If the thermocouple is producing more than 15 millivolts, replace faulty valve.  
3.  
The pilot is burning, there  
is no gas burning, the  
valve knob is in the ON  
position, and the ON/  
OFF switch is in the ON  
position.  
ON/OFF switch or wires  
are defective.  
Check the ON/OFF switch and wires for proper connections. Place the  
jumper wires across the terminals at the switch. If the burner comes on,  
replace the defective switch. If the switch is OK, place the jumper wires  
across the switch wires at the gas valve. If the burner comes on, the wires  
are faulty or connections are bad.  
B.  
Thermopile may not be  
generating sufcient  
millivoltage.  
If the pilot ame is not close enough physically to the thermopile, adjust the  
pilot ame.  
Be sure the wire connections from the thermopile at the gas valve terminals  
are tight and that the thermopile is fully inserted into the pilot bracket.  
Check the thermopile with a millivolt meter. Take the reading at TH-TP&TP  
terminals of the gas valve. The meter should read 325 millivolts minimum  
while holding the valve knob depressed in the pilot position, with the pilot lit,  
and the ON/OFF switch in the OFF position. Replace the faulty thermopile of  
the reading is below the specied minimum.  
With the pilot in the ON position, disconnect the thermopile leads from  
the valve. Take a reading at the thermopile leads. The reading should be  
325 millivolts minimum. Replace the thermopile if the reading is below the  
minimum.  
C.  
Defective valve.  
Turn the valve knob to the ON position. Place the ON/OFF switch in the ON  
position. Check the millivolt meter at the thermopile terminals. The millivolt  
meter should read greater than 125mV. If the reading is acceptable, and if  
the burner does not come on, replace the gas valve.  
D.  
E.  
Plugged burner orice.  
Check the burner orice for stoppage. Remove stoppage.  
Wall switch or wires are  
defective.  
Follow the corrective action in Symptom and Possible Cause 1.A. above.  
Check the switch and wiring. Replace where defective.

B. Intellire Ignition System  
Symptom  
Possible Causes  
Corrective Actions  
1.  
The ignitor/module makes  
noise, but no spark.  
A.  
B.  
Incorrect wiring.  
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are  
connected to the correct terminals on the module and the pilot assembly.  
Reversed wires at the module may cause the system to make a sparking  
noise, but the spark may not be present at pilot hood.  
Loose connections or  
electrical shorts in the  
wiring.  
Verify there are no loose connections or electrical shorts in wiring from  
module to pilot assembly. The rod closest to the pilot hood should be ignitor.  
Verify connections underneath pilot assembly are tight; also verify the  
connections are not grounding out to the metal chassis, pilot burner, pilot  
enclosure, mesh screen if present, or any other metal object.  
C.  
D.  
Ignitor gap is too large.  
Faulty module.  
Verify gap of ignitor to pilot hood. The gap should be approximately .17 in. or  
1/8 in.  
Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor  
wire “I” from module. Place ON/OFF rocker switch or wall switch in ON  
position. Hold ground wire about 3/16 in. away from “I” terminal on module. If  
there is no spark at “I” terminal, module must be replaced. If there is a spark  
at “I” terminal, module is ne. Inspect pilot assembly for shorted sparker wire  
or cracked insulator around electrode.  
2.  
Pilots won’t light, there is  
no noise or spark.  
A.  
B.  
Transformer installed  
incorrectly.  
Verify that transformer is installed and plugged into module. Check voltage of  
transformer under load at space connection on module with ON/OFF switch  
in ON position. Acceptable readings of a good transformer are between 3.2  
and 2.8 volts AC.  
A shorted or loose  
connection in wiring  
conguration or wiring  
harness.  
Remove and reinstall the wiring harness that plugs into module. Verify there is  
a tight t. Verify pilot assembly wiring to module. Remove and verify continuity  
of each wire in wiring harness.  
C.  
D.  
E.  
Improper wall switch  
wiring.  
Verify wall switch is wired correctly.  
Module not grounded.  
Verify black ground wire from module wire harness is grounded to metal  
chassis of appliance.  
Faulty module.  
Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor  
wire “I” from module. Place ON/OFF rocker switch or wall switch in ON  
position. Hold ground wire about 3/16 in. away from “I” terminal on module. If  
there is no spark at “I” terminal module must be replaced. If there is a spark at  
“I” terminal, module is ne. Inspect pilot assembly for shorted sparker wire or  
cracked insulator around electrode.  
3.  
Pilot lights but continues  
to spark, and main burner  
will not ignite. (If the pilot  
continues to spark after  
the pilot ame has been  
lit, ame rectication has  
not occurred.)  
A.  
B.  
A shorted or loose  
connection in sensor rod.  
Verify all connections to wiring diagram in manual. Verify connections  
underneath pilot assembly are tight. Verify connections are not grounding out  
to metal chassis, pilot burner, pilot enclosure or screen if present, or any other  
metal object.  
Poor ame rectication or  
contaminated sensor rod.  
Verify ame is engulng sensor rod. If the pilot assembly does not have a  
ground strap, consider installing one to increase ame rectication. Verify  
correct pilot orice is installed and inlet gas specications are met. Flame  
carries rectication current, not the gas. If ame lifts from pilot hood, the  
circuit is broken. A wrong orice or too high an inlet pressure can cause pilot  
ame to lift. The sensor rod may be contaminated. Clean sensor rod with  
emery cloth.  
C.  
D.  
Module is not grounded.  
Verify that module is securely grounded to metal chassis of appliance. Verify  
that the wire harness is rmly connected to module.  
Damaged pilot assembly  
or dirty sensor rod.  
Verify that ceramic insulator around the sensor rod is not cracked, damaged,  
or loose. Verify connection from sensor rod to white sensor wire. Clean  
sensor rod with emery cloth to remove any contaminants that may have  
accumulated on sensor rod. Verify continuity with a multimeter with ohms set  
at lowest range.  
E.  
Faulty module.  
Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor  
wire “I” from module. Place ON/OFF rocker switch or wall switch in ON  
position. Hold ground wire about 3/16 in. away from “I” terminal on module. If  
there is no spark at “I” terminal, module must be replaced. If there is a spark  
at “I” terminal, module is ne. Inspect pilot assembly for shorted sparker wire  
or cracked insulator around electrode.
