Hearth & Home Technologies
LIMITED LIFETIME WARRANTY
Hearth & Home Technologies, 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.

implied, or in contract, tort or otherwise, shall be limited to replacement, repair, or refund, as specified above. In no
event will HHT be liable for any incidental or consequential damages caused by defects in the appliance. Some states
do not allow exclusions or limitation of incidental or consequential damages, so these limitations may not apply to you.
This warranty gives you specific rights; you may also have other rights, which vary from state to state. 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

Figure 3.4 Control Module
Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 3.4.
OFF Position: Appliance will ignore all power inputs and
will not respond to any commands from a wall switch or
remote. The unit should be in the OFF position during
installation, service, battery installation, fuel conversion,
and in the event that the control goes into LOCK-OUT
mode as a result of an error code.
ON Position: Appliance will ignite and run continuously
in the HI flame setting, with no adjustment in flame
output. This mode of operation is primarily used for
initial installation or power outage operation with battery
backup.
REMOTE Position: Appliance will initiate commands
from an optional wired wall switch and/or the wireless
remote (RC200).
2. If using a wired wall switch with the module in REMOTE
mode, the flame output can be adjusted with the HI/LO
selector switch on the module. See Figure 3.4. Note
that the flame HI/LO selector switch will become inactive
once the remote control (RC200) is programmed to the
control module. Note that the control module will always
ignite the fireplace on HI and remain so for the initial 10
seconds of operation. If the HI/LO is switched to the
LO position, the flame output will automatically drop to
the lowest setting after the flame has been established
for 10 sec. After this 10 second period, the flame can
be adjusted from HI to LO with the switch.

5 Frequently Asked Questions and Troubleshooting
A. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass This is a result of gas combustion and temperature variations. As the fireplace warms, this
condensation will disappear.
Blue flames This is a result of normal operation and the flames will begin to yellow as the fireplace is al-
lowed to burn for 20 to 40 minutes.
Odor from fireplace
When first operated, this fireplace 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 fireplace. See
Section 3.F
Film on the glass This is a normal result of the curing process of the paint. 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 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.
Power Outages
(battery backup)
This appliance can be operated on battery power in the event of a power outage. To ac-
cess the battery pack, the decorative front must be removed. Refer to Section 3.H for more
details.
Wall above appliance feels hot to
the touch. (In-Wall installations only)
No action necessary. This appliance ships with a non-combustible material attached. Speci-
fications of the attached non-combustible material are listed in the Installer’s Manual for this
appliance.

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 igniter and flame sense wires 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. Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
2. Pilot won’t light,
there is no noise or
spark.
A. No power, transformer installed
incorrectly, or depleted batteries.
Verify that transformer is installed and plugged into module. Check
voltage of transformer at connection to module. Acceptable read-
ings of a good transformer are between 6.4 and 6.6 volts DC. Bat-
tery power supply voltage must be at least 4 volts. If less than 4
volts, replace batteries.
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. Verify that 110-120 VAC power is “ON” to junction box.
D. Module not grounded. Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
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.
B. Ignitor gap is too large. Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
C. Module is not grounded. Verify module is securely grounded to metal chassis of appliance.
D. Pilot valve solenoid. Verify that 1.5 to 1.8 VDC is supplied to pilot solenoid from module.
If below 1.5 volts, replace module. If 1.5 volts or greater, replace
valve.

Troubleshooting (continued)
Symptom Possible Cause Corrective Action
4. Pilot lights but contin-
ues 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. A shorted or loose connection in flame
sensing rod.
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify
flame sense or igniter wires are not grounding out to metal
chassis, pilot burner, pilot enclosure or screen if present, or
any other metal object.
B. Poor flame rectification or contaminated
flame sensing rod.
With fixed glass assembly in place, verify that flame is en-
gulfing flame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. With a multi-
meter, verify that current in series between module and
sense lead is at least 0.14 microamps. Verify correct pilot
orifice is installed and gas inlet is set to pressure specifi-
cations. Polish flame sensing rod with fine steel wool 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. Polish flame sens-
ing rod with fine steel wool to remove any contaminants
that may have accumulated on flame sensing rod. Verify
continuity with a multi-meter with ohms set at lowest range.
Replace pilot if any damage is detected.
