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 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.

I. Control Module Operation  
1. The control module has an ON/OFF/REMOTE selector  
switch that must be set. See Figure 2.4.  
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.  
SELECTOR  
SWITCH  
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.  
STATUS INDICATOR LED  
REMOTE Position: Appliance will initiate commands  
from an optional wired wall switch and/or the wireless  
remote (RC300).  
FLAME HI/LO SWITCH  
NG/LP SETTING  
Figure 2.4 Control Module  
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 2.4. 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.  
Nine Hour Safety Shutdown Feature  
This appliance has a safety feature that automatically  
shuts down the fireplace after 9 hours of continuous  
operation without receiving a command from the  
RC300 remote.  
J. Before Lighting Fireplace

shuts down the fireplace after 9 hours of continuous  
operation without receiving a command from the RC300  
remote.  
• Verify all shipping materials have been removed from  
inside and/or underneath the firebox.  
• Review proper placement of logs, ember material and/or  
other decorative materials.  
4. If you intend to use both a wired wall switch and the  
optional RC200/RC300 remote control to operate your  
fireplace, the wall switch will override any commands  
given by the remote.  
• Check the wiring.  
• Check the air shutter adjustment.  
• Ensure that there are no gas leaks.  
5. Module Reset

ISSUE  
SOLUTIONS  
This is a result of gas combustion and temperature variations. As the fireplace 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 fireplace is al-  
lowed to burn for 20 to 40 minutes.  
Blue flames  
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.  
Odor from fireplace  
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.  
Film on the glass  
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.  
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.  
Is it normal to see the pilot flame burn  
continually?

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.  
B. Constructing the Appliance Chase  
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 out-  
side walls of the home to prevent cold air drafting prob-  
lems. 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.  
To further prevent drafts, the wall shield and ceiling fire-  
stops should be caulked with caulk with a minimum of

NOTICE: DO NOT install a hearth that is greater than  
one inch thick. Hearth will interfere with installation of  
glass assembly. Total hearth height must not exceed one  
inch from bottom of appliance when appliance is installed  
directly on floor (including mortar, backer material, etc.)  
E. Hearth Extension  
WARNING! Risk of Fire! Non-combustible hearth exten-  
sion may be required when appliance is installed on com-  
bustible surface.  
•
Hearth extension must be non-combustible and  
serves to protect combustible floors in front of appli-  
ance. See Figure 5.11.  
If a hearth greater than one inch in thickness is desired,  
the appliance must be raised by the equivalent height  
to ensure that the hearth does not interfere with the  
installation of the glass assembly required for fireplace  
operation. See Figure 5.11.  
• The base of the fireplace may sit on a combustible sur-  
face. See Figure 5.11. The area in front of the appli-  
ance must be protected by a non-combustible hearth  
extension, unless the appliance is raised a minimum  
of three inches above the combustible floor or hearth.  
See Figure 5.11 and Figure 5.12.

Non-Combustible Wall Penetration  
A. Pipe Clearances to Combustibles  
If the hole being penetrated is surrounded by non-com-  
bustible materials such as concrete, a hole with diameter  
one inch greater than the pipe is acceptable.  
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  
Whenever a non-combustible wall is penetrated, the wall  
shield firestop is only required on one side and no heat  
shield is necessary.  
Failure to keep insulation or other material away from  
vent pipe may cause overheating 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.  
DO NOT PACK WITH  
INSULATION OR OTHER  
MATERIAL  
‡ ,f wall thickness is less than 4 in. the e[isting heat shields must be field trimmed. ,f  
wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.  
‡ ,f wall thickness is less than 4-3/8 the e[isting heat shields must be field trimmed.  
,f wall thickness is greater than 7-ꢀ/8 in. a DVP-HSM-B will be required.

Combustible Wall Penetration  
Whenever a combustible wall is penetrated, you must  
frame a hole for the wall shield firestop(s). The wall shield  
firestop maintains minimum clearances and prevents cold  
air infiltration.  
* Shows center of vent framing hole with minimum vertical for top venting. The  
center of the hole is one (1) in. (25.4 mm) above the center of the horizontal  
vent pipe.  
• The opening must be framed on all four sides using the  
same size framing materials as those used in the wall  
construction.  
Figure 8.2 Wall Penetration  
• 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.H. for information for regarding the in-  
stallation of a horizontal termination cap.

I. Air Shutter Setting  
Air shutter settings should be adjusted by a qualified ser-  
vice technician at the time of installation. The air shutter is  
set at the factory for minimum vertical vent run. Adjust air  
shutter for longer vertical runs. See Figure 14.11.  
Flame Appearance  
• After 15 minutes, the flame will be a yellow/blue mix.  
The front flames may be blue at this time.  
• After 30 minutes, the flame should be yellow with some  
blue flame near the burner ports.  
• After 1 hour, the flame will be at is maximum maturity.  
Note: Visually, a propane flame may differ from a natural  
gas flame. This is due to the different chemical compositions  
that make up both fuel types. In general, the LP flames may  
be a little shorter and much brighter than a natural gas flame.  
To adjust air shutter:  
• Loosen the screw on the burner assembly.  
• The air shutter should only be adjusted in increments of  
1/8 in.  
• To close the air shutter, turn shutter clockwise.  
• To open air shutter, turn shutter counterclockwise.  
• Tighten the screw.  
NOTICE: Flame should not appear orange or stretch to  
the top refractory. If sooting occurs, provide more air by  
opening the air shutter.

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 AC. 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.  
D. Module not grounded.  
Verify that 110/VAC power is “ON” to junction box.  
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.  
D. Pilot valve solenoid.  
Verify module is securely grounded to metal chassis of appliance.  
Verify that 1.5 to 1.8 VDC is supplied to pilot solenoid from module.
