B. Limited Lifetime Warranty
4021-645F 02-18-13 Page 1 of 2
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.

• Contact your installing dealer for warranty service. If the installing dealer is unable to provide necessary parts, contact
the nearest HHT authorized dealer or supplier. Additional service fees may apply if you are seeking warranty service
from a dealer other than the dealer from whom you originally purchased the product.
• Check with your dealer in advance for any costs to you when arranging a warranty call. Travel and shipping charges
for parts are not covered by this warranty.
This warranty is void if:
• The appliance has been over-fired or operated in atmospheres contaminated by chlorine, fluorine, or other damaging
chemicals. Over-firing can be identified by, but not limited to, warped plates or tubes, rust colored cast iron, bubbling,
cracking and discoloration of steel or enamel finishes.
• The appliance is subjected to prolonged periods of dampness or condensation.
• There is any damage to the appliance or other components due to water or weather damage which is the result of, but
not limited to, improper chimney or venting installation.
LIMITATIONS OF LIABILITY:
• The owner’s exclusive remedy and HHT’s sole obligation under this warranty, under any other warranty, express or
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
EXPRESSED WARRANTY SPECIFIED ABOVE.
WARRANTY EXCLUSIONS:
This warranty does not cover the following:
• Changes in surface finishes as a result of normal use. As a heating appliance, some changes in color of interior and
exterior surface finishes may occur. This is not a flaw and is not covered under warranty.

or other external sources and residues left on the plated surfaces from the use of abrasive cleaners or polishes.
• Repair or replacement of parts that are subject to normal wear and tear during the warranty period. These parts
include: paint, wood, pellet and coal gaskets, firebricks, grates, flame guides, batteries and the discoloration of glass.
• Minor expansion, contraction, or movement of certain parts causing noise. These conditions are normal and com-
plaints related to this noise are not covered by this warranty.
• Damages resulting from: (1) failure to install, operate, or maintain the appliance in accordance with the installation
instructions, operating instructions, and listing agent identification label furnished with the appliance; (2) failure to
install the appliance in accordance with local building codes; (3) shipping or improper handling; (4) improper opera-

caused by tightly sealed constructions, insufficient make-up air supply, or handling devices such as exhaust fans or
forced air furnaces or other such causes; (6) use of fuels other than those specified in the operating instructions; (7)
installation or use of components not supplied with the appliance or any other components not expressly authorized
and approved by HHT; (8) modification of the appliance not expressly authorized and approved by HHT in writing;
and/or (9) interruptions or fluctuations of electrical power supply to the appliance.
• Non-HHT venting components, hearth components or other accessories used in conjunction with the appliance.
• Any part of a pre-existing fireplace system in which an insert or a decorative gas appliance is installed.
• HHT’s obligation under this warranty does not extend to the appliance’s capability to heat the desired space. Informa-
tion is provided to assist the consumer and the dealer in selecting the proper appliance for the application. Consider-
ation must be given to appliance location and configuration, environmental conditions, insulation and air tightness of

Figure 2.3 Control Module
J. Control Module Operation
1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 2.3.
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 (RC300).
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 2.3. Note
that the flame HI/LO selector switch will become inactive
once an optional remote control (RC200/RC300) 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.
3. The control module has safety feature that automatically
shuts down the fireplace after 9 hours of continuous
operation without receiving a command from the RC300
remote.
4. If you intend to use both an optional wired wall switch
and the RC300 remote control to operate your fireplace,
the wall switch will override any commands given by
the remote.
5. Module Reset
This module may lock-out under certain conditions.
When this occurs, the appliance will not ignite or
respond to commands. The module will go into lock-out
mode by emitting three audible beeps, then continuously
displaying a RED/GREEN error code at its status
indicator LED.
• Check battery tray. Remove batteries if installed.
Batteries should only be installed for use during power
outages. See Section G.
• Locate the module selector switch. (See Figure 2.3).
• Set the module selector switch to the OFF position.
• Wait five (5) minutes to allow possible accumulated gas
to clear.
• Set the module selector switch to ON or REMOTE
position.
• Start the appliance.

M. After Fireplace is Lit
N. 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 flames 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.
Odor from appliance
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.
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.
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 appliance.
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.

Figure 4.2
E. Negative Pressure
WARNING! Asphyxiation Risk! Negative pressure can
cause spillage of combustion fumes and soot. Fireplace
needs to draft properly for safety.
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 results from the imbalance of air
available for the fireplace to operate properly. Causes for
this imbalance include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
• Location of return-air to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks)
To minimize the effects of negative air pressure, the fol-
lowing must be considered:
• Install the fresh 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 of “sealed can” design; attic
hatches weather stripped or sealed; and attic mounted
ductwork 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.
Location of the fireplace and chimney will affect perfor-
mance. As shown in Figure 4.2, the chimney should:
• Be installed through the warm space 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.
Offsets can restrict draft so their use should be minimized.
Consider the fireplace location relative to floor and ceiling
and attic joists.
