B. Limited Lifetime Warranty 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 components 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.

H. 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 an error code at its status indicator LED.

L. 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 allowed 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 materials from manufacturing. Odor may also be released from
finishing materials and adhesives used near the fireplace. These circumstances may require
additional curing related to the installation environment.
Film on the glass
Metallic noise
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. A non-abrasive cleaner such as gas appliance 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 fireplace.

operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.
• Carefully remove the appliance and components from
the packaging.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fire officials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
• If packaged separately, the log set and appliance grate
must be installed.
Before installing, determine the following:
• Read all of the instructions before starting the installation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
• Where the appliance is to be installed.
• The vent system configuration to be used.
• Gas supply piping requirements.
• Electrical wiring requirements.
• The vent system components and decorative doors and
fronts may be shipped in separate packages.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged, incomplete or substitute components. Keep appliance dry.

Framing and Clearances
A. Selecting Appliance Location
When selecting a location for the appliance it is important to
consider the required clearances to walls (see Figure 5.1).
NOTICE: Illustrations reflect typical installations and are
FOR DESIGN PURPOSES ONLY. Illustrations/diagrams
are not drawn to scale. Actual installation may vary due to
individual design preference.
WARNING! Risk of Fire or Burns! Provide adequate
clearance around air openings and for service access.

B. Constructing the Appliance Chase
To further prevent drafts, the wall shield and ceiling firestops should be caulked with caulk with a minimum of
300ºF continuous exposure rating to seal gaps. Gas line
holes and other openings should be caulked with caulk
with a minimum of 300ºF continuous exposure rating or
stuffed with unfaced insulation. If the appliance is being
installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the
room.
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield
firestops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.
C. Clearances
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.
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.
WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
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, in regions where cold
air infiltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.
• Insulation and other materials must be secured to prevent
accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to maintain airspace may cause overheating and
a fire.

Vent Clearances and Framing
A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
• Between ceiling firestops
• Between wall shield firestops
• Around vent system
• DVP pipe - A wall shield firestop is required on one side
only on interior walls. If your local inspector requires a
wall shield firestop on both sides, then both wall shield
firestops must have a heat shield (refer to Section 16.B.)
attached to them.
• See Section 10.J. for information for regarding the installation of a horizontal termination cap.
Failure to keep insulation or other material away from
vent pipe may cause over heating and fire.
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
• DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick.
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If
wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.
