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  
officials 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 Section 3.  
The vent system configuration to be used. See Sections  
4 and 5.  
•
•
•
Gas supply piping. See Section 9.  
Electrical wiring. See Sections10  
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 10.  
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 fireplace.  
Avoid installing the fireplace 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 fireplaces 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 fireplaces  
successfully. Considerations for successful draft include:  
•
•
Preventing negative pressure.  
Location of fireplace and chimney.  
•
Negative Pressure  
Negative pressure results from the imbalance of air avail-  
able for the fireplace to operate properly. Causes for this  
imbalance include:  
Location of the fireplace 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.  
•
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 fire.  
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.  
•
•
•
•
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).  
Offsets can restrict draft so their use should be minimized.  
Consider the fireplace location relative to floor and ceiling  
and attic joists.

B. Construct the Appliance Chase  
WARNING  
Fire Risk  
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.  
•
Construct chase to all clearance  
specifications in manual.  
Locate and install appliance to all  
clearance specifications 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 floor of the chase  
should be insulated. Vapor and air infiltration 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 sheetrocked and taped for  
maximum air tightness.  
To further prevent drafts, gas line holes and other openings  
should be caulked with high temperature caulk or stuffed  
with unfaced insulation. If the appliance is being installed  
on a cement slab, we recommend that a layer of plywood  
be placed underneath to prevent conducting cold up into the  
room.

U.L. listed gas appliances are tested and approved without  
requiring changes for elevations from 0 to 2000 ft in the USA  
and Canada.  
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 orifice 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 orifice size, check with the local gas utility.

E. 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 in  
your absence 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. Clean  
glass doors (if installed). Close the doors (if installed) 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.

F. Frequently Asked Questions  
Issue  
Condensation on the glass  
Solutions  
This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will  
disappear.  
Blue flames  
This is a result of normal operation and the flames will begin to yellow as the appliance is allowed to burn for 20 to  
40 minutes.  
Odor from appliance  
Film on the glass  
When first operated, this appliance may release an odor for the first 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  
fireplace 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 fireplace.  
Is it normal to see the pilot  
flame burn continually?  
In an Intellifire ignition system it is normal to see the pilot flame, but it should turn off when ON/OFF is turned off.  
In a standing pilot system the pilot will always stay on.

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 qualified service person in the diagnosis of a problem and the  
corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician.  
A. Standing Pilot Ignition System  
Symptom  
Possible Causes  
Defective ignitor.  
Corrective Actions  
Check the spark at the electrode and pilot. If there is no spark and the  
electrode wire is properly connected, replace the ignitor.  
1.  
After repeated triggering  
of the red or black piezo  
ignitor button, the spark  
ignitor will not light the  
pilot.  
A.  
B.  
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 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 flame impinges on the thermocouple. Clean and/or  
adjust the pilot for maximum flame 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 sufficient  
millivoltage.  
If the pilot flame is not close enough physically to the thermopile, adjust the  
pilot flame.  
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 specified 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 orifice.  
Check the burner orifice 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. Intellifire Ignition System  
Symptom  
The ignitor/module makes  
noise, but no spark.  
Possible Causes  
Incorrect wiring.  
Corrective Actions  
1.  
A.  
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.  
B.  
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 fine. 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  
configuration or wiring  
harness.  
Remove and reinstall the wiring harness that plugs into module. Verify there is  
a tight fit. 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 fine. 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 flame has been  
lit, flame rectification has  
not occurred.)  
A.  
B.  
A shorted or loose  
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.  
connection in sensor rod.  
Poor flame rectification or  
contaminated sensor rod.  
Verify flame is engulfing sensor rod. If the pilot assembly does not have a  
ground strap, consider installing one to increase flame rectification. Verify  
correct pilot orifice is installed and inlet gas specifications are met. Flame  
carries rectification current, not the gas. If flame lifts from pilot hood, the  
circuit is broken. A wrong orifice or too high an inlet pressure can cause pilot  
flame 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 firmly 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

D. Limited Lifetime Warranty  
Gas Appliance (Fireplace)  
Limited Lifetime Warranty  
HEARTH & HOME TECHNOLOGIES INC. (“HHT”) extends the following warranty for HEATILATOR® gas  
appliances installed in the United States of America or Canada (the "Appliance"). Dealers and employees of HHT  
have no authority to make any warranty or authorize any remedies in addition to or inconsistent with the terms of  
this warranty.  
Limited Lifetime Warranty  
HHT warrants the Appliance for component failure due to a manufacturing defect of any of the following components: combustion chamber,  
burner pan, and logs. The Limited Lifetime Warranty specified above is subject to the conditions, exclusions and limitations listed below, is for  
the period the Appliance is owned by the original homeowner only, and is nontransferable.  
1 Year Limited Warranty  
HHT warrants the Appliance to be free from failure of any of the following components for a period of one year after installation: valve, flexible  
gas line connector, glass panel, fan, direct vent chimney components, factory paint, gasket, piezo ignitor, thermopile, thermocouple, junction  
box, pilot assembly, shutoff valve, high limit switch, refractory liners, transformer, and control box. If the Heatilator Appliance is found to be  
defective in either material or workmanship within one year of the date of original installation, HHT will provide replacement parts at no charge  
and pay reasonable labor and freight costs, and is for the period of one year following the date of original installation of the Appliance.  
Conditions, Exclusions, & Limitations of Liability  
A. Both the Limited Lifetime and 1 Year Limited Warranties supplied by HHT apply only while the Appliance is in its location of original  
installation. HHT’s obligation under this warranty does not extend to damages resulting from (1) installation, operation or maintenance  
of the Appliance not in accordance with the Installation Instructions, Operating Instructions, and the Listing Agent Identification Label  
furnished with the Appliance; (2) installation which does not comply with local building codes; (3) shipping, improper handling, improper  
operation, abuse, misuse, accident or unworkmanlike repairs; (4) environmental conditions, inadequate ventilation or drafting caused by  
tight sealing construction of the structure, air handling devices such as exhaust fans or forced air furnaces, or other causes; (5) use of  
fuels other than those specified in the Operating Instructions; (6) installation or use of components not supplied with the Appliance or any  
other components not expressly authorized and approved by HHT; and/or (7) modification of the Appliance not expressly authorized and  
approved by HHT in writing. This warranty is limited to only the component parts manufactured or supplied by HHT.  
B. HHT’s liability under both the Limited Lifetime Warranty and the 1 Year Limited Warranty is limited to the replacement and repair of  
defective components or workmanship during the applicable period. HHT may fully discharge all of its obligations under such warranties  
by repairing the defective component(s) or at HHT’s discretion, providing replacement parts at no charge and paying reasonable labor  
and freight costs.  
C. EXCEPT TO THE EXTENT PROVIDED BY LAW, HHT MAKES NO EXPRESS WARRANTIES OTHER THAN THE WARRANTY  
SPECIFIED HEREIN. THE DURATION OF ANY IMPLIED WARRANTY IS LIMITED TO DURATION OF THE WARRANTY SPECIFIED  
ABOVE.  
D. Some states do not allow exclusions or limitations of incidental or consequential damages, so those limitations may not apply to you.  
This warranty gives you specific rights; you may also have other rights which vary from state to state.
