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.  
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 2.3 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 2.3. 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.

K. After Appliance is Lit  
Initial Break-in Procedure  
• The appliance should be run three to four hours  
continuously on high.  
• Turn the appliance off and allow it to completely cool.  
• Remove fixed glass assembly. See Section 12.F.  
• Clean fixed glass assembly. See Section 3.  
• Replace the fixed glass assembly and run continuously  
on high an additional 9 hours.  
This cures the materials used to manufacture the fire-  
place.  
NOTICE! Open windows for air circulation during ap-  
pliance break-in.  
• Some people may be sensitive to smoke and odors.  
• Smoke detectors may activate.  
L. 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.  
Is it normal to see the pilot flame burn  
continually?

Prepare the existing solid fuel masonry or factory built  
non-combustible firebox for installation.  
D. Fireplace Conversion Notice  
Permanently attach the label with the following warning to  
the inside lower back of the fireplace firebox into which the  
insert is being installed. Silicone or mechanical fasteners  
may be required to properly secure the label.  
A. Inspection and Cleaning  
Prior to installing the gas insert:  
• Have the chimney and adjacent structure inspected  
and cleaned by qualified professionals. Hearth & Home  
Technologies recommends that NFI or CSIA certified  
professionals, or technicians under the direction of certi-  
fied professionals, conduct a minimum of a NFPA 211  
Level 2 inspection of the chimney.  
WARNING! Risk of Fire! This fireplace has been con-  
verted for use with a gas fireplace insert only and cannot  
be used for burning wood or solid fuels unless all original  
parts have been replaced, and the fireplace re-approved  
by the authority having jurisdiction.  
• Replace component parts of the chimney and fireplace  
as specified by the professionals.  
E. Electrical Outlet Box  
An outlet box may be installed in a bottom back corner of  
the existing solid fuel masonry or factory built fireplace to  
power the appliance. Each insert ships standard with a  
cord assembly to permit blowers or other optional acces-  
sories to be used. The accessories plug into the new out-  
let box or may be routed out onto the hearth to a nearby  
outlet.  
• Ensure all joints are properly engaged and the chimney  
is properly secured.  
• Ensure combustible mantel and surround clearances  
comply with applicable codes and regulations for solid-  
fuel fireplaces. In the absence of local or regional codes,  
refer to NFPA 211.  
• Ensure chimney is constructed of non-combustible  
materials.  
• Ensure chimney is clean and in good working order.  
• Ensure that all chimney cleanouts fit properly to prevent  
air leakage into chimney.  
B. Flue Damper  
Fully lock the solid fuel fireplace’s flue damper in the open  
position, OR completely remove it.  
C. Gas Line  
Note: If the factory built fireplace has no gas access hole  
provided, an access hole of 1 inch (25 mm) diameter or  
less may be drilled through the lower sides or bottom of the  
firebox in a proper workmanship - like manner. This access  
hole must be plugged with non-combustible insulation after  
the gas supply line has been installed.  
• Install gas line into firebox cavity.  
• Check local codes and gas line sizing requirements  
following NFPA51. See Section 9.  
• It is recommended that extra length of gas line be  
installed within the existing wood burner or masonry  
fireplace to allow removal of the insert for future servicing  
needs.

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 AC. Bat-  
tery power supply voltage must be at least 4 volts. If below 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 120/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.  
If below 1.5 volts, replace module. If 1.5 volts or greater, replace  
valve.
