Hearth & Home Technologies Inc.
LIMITED LIFETIME WARRANTY
Hearth & Home Technologies Inc., on behalf of its hearth brands (”HHT”), extends the following warranty for
HHT gas, wood, pellet, coal and electric hearth appliances that are purchased from an HHT authorized dealer.
WARRANTY COVERAGE:
HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership
of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance
will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered compo-
nents manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period,
HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its
obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product
itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty
is subject to conditions, exclusions and limitations as described below.
WARRANTY PERIOD:
Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage
begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent,
authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months
following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for
parts and labor for covered components is produced in the following table.
The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for
gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These
time periods reflect the minimum expected useful lives of the designated components under normal operating conditions.

K. Frequently Asked Questions
ISSUE
SOLUTIONS
This is a result of gas combustion and temperature variations. As the appliance warms, this
condensation will disappear.
Condensation on the glass
This is a result of normal operation and the flames will begin to yellow as the appliance is al-
lowed to burn for 20 to 40 minutes.
Blue flames
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. Odor may
also be released from finishing materials and adhesives used around the appliance.
Odor from appliance
Film on the glass
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.
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 appliance.
Metallic noise
In an intermittent pilot ignition system (IPI), the pilot flame should turn off when appliance is
turned off. Some optional control systems available with IPI models may allow pilot flame to
remain lit. In a standing pilot system the pilot will always stay on.
Is it normal to see the pilot flame burn
continually?

Check the LP (propane) tank. You may be out of fuel.
C. Ignitor.
Check the spark at the electrode and pilot. If no spark and electrode
wire is properly connected, replace the ignitor. Verify that there is no
short in electrode wire.
D. Pilot or misaligned electrode
(spark at electrode).
Using match, light the pilot. If the pilot lights, turn off the pilot and
trigger the 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 elec-
trode and pilot is one-eighth in. to have a strong spark. If the gap is
OK, replace the pilot.
2. The pilot will not stay lit
after carefully following
the lighting instructions.
A. Thermocouple.
Check that the pilot flame impinges on the thermocouple. Adjust the
pilot for proper flame impingement.
Ensure that the thermocouple connection at the gas valve is fully in-
serted and tight (hand tighten plus 1/4 turn).
Verify proper voltage output from the thermocouple to the valve.
Place one millivolt meter lead wire on the thermocouple copper lead.
Place the second lead wire on the solder button on the back of the
valve (blue wire). Start the pilot and hold the valve knob in. The mil-
livolt reading should read 8-16 millivolts. If millivolt reading is less
than 8 millivolts, replace thermocouple.
B. Improper gas inlet pressure. Natural gas should be 5-10 in. w.c. LP should be 11-13 in. w.c. Verify
pressure with manometer.
C. Valve.
If the thermocouple is producing 8-16 millivolts, replace control valve.
3. The pilot is burning,
there is no burner
A. ON/OFF switch or wires.
Check the ON/OFF switch and wires for proper connections. Place
the jumper wires across the terminals at the ON/OFF switch. If the
burner comes on, replace the ON/OFF switch. If the ON/OFF switch
is OK, place the jumper wires across the ON/OFF switch wires at the
gas valve. If the burner comes on, the wires are faulty or connections
are bad.

in the ON position, and
the ON/OFF switch is in
the ON position.
B. Thermopile may not be gen-
erating sufficient millivoltage.
Check that the pilot flame impinges thermopile properly.
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 350 mil-
livolts 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 thermopile if the reading is below the specified mini-
mum.
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 350 millivolts minimum. Replace the thermopile if the read-
ing is below the minimum.

B. IntelliFire Ignition System
Symptom
Possible Cause
Corrective Action
1. Pilot won’t light.
The ignitor/module
makes noise, but no
spark.
A. Incorrect wiring.
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are
connected to correct terminals on module and pilot assembly.
B. Loose connections or electrical
shorts in the wiring.
Verify no loose connections or electrical shorts in wiring from mod-
ule to pilot assembly. Verify connections underneath pilot assembly
are tight; also verify connections are not grounding out to metal
chassis, pilot burner, pilot enclosure, mesh screen if present, or any
other metal object.
C. Ignitor gap is too large.
D. Module.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place a grounded wire about 3/16 in. (5
mm) away from “I” terminal on module. Place ON/OFF rocker switch
or wall switch in ON position. 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. Replace pilot if necessary.
2. Pilot won’t light,
there is no noise or
spark.
A. No power or transformer installed
incorrectly.
Verify that transformer is installed and plugged into module. Check
voltage of transformer under load at spade 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.
B. A shorted or loose connection in
wiring configuration or wiring har-
ness.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fit. Verify pilot assembly wiring to module. Re-
move and verify continuity of each wire in wiring harness. Replace
any damaged components.
C. Improper wall switch wiring.
D. Module not grounded.
Verify that 120/VAC power is “ON” to junction box.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
E. 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. 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 sparks, but
Pilot will not light.
A. Gas supply.
Verify that incoming gas line ball valve is “open”. Verify that inlet
pressure reading is within acceptable limits, inlet pressure must not
exceed 14 in. W.C.
B. Ignitor gap is too large.
C. Module is not grounded.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Verify module is securely grounded to metal chassis of appliance.
D. Module voltage output / Valve/Pilot Verify battery voltage is at least 2.7 volts. Replace batteries if volt-
solenoid ohms readings. age is below 2.7.

gulfing flame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. Verify cor-
rect pilot orifice is installed and gas inlet is set to pressure
specifications. Clean flame sensing rod with emery cloth to
remove any contaminants that may have accumulated on
flame sensing rod.
C. Module is not grounded.
Verify module is securely grounded to metal chassis of ap-
pliance. Verify that wire harness is firmly connected to the
module.
D. Damaged pilot assembly or contami-
nated flame sensing rod.
Verify that ceramic insulator around the flame sensing rod
is not cracked, damaged, or loose. Verify connection from
flame sensing rod to white sensor wire. Clean flame sensing
rod with emery cloth to remove any contaminants that may
have accumulated on flame sensing rod. Verify continuity
with a multimeter with ohms set at lowest range. Replace
pilot if any damage is detected.
E. 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. If there is no spark at “I”
terminal module must be replaced. If there is a spark at “I”
terminal, module is fine.
