NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Maximum inlet gas supply pressure to the
appliance is 10.5 inches water column (19.95
MmHg) for natural gas and 13.0 inches water
column (24.25 MmHg) for propane.
The appliance must be isolated from the gas
supply piping system (by closing its individual
manual shut-off valve) during any pressure test-
ing of the gas supply piping system at test
pressures equal to or less than
¹⁄₂
psig (3.5 kPa).
The appliance and its individual shut-off valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at pressures in excess of
¹⁄₂
psig
(3.5 kPa).
These appliances must not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.
WARNING: FAILURE TO COMPLY WITH
THE INSTALLATION AND OPERATING IN-
STRUCTIONS PROVIDED IN THIS DOCU-
MENT WILL RESULT IN AN IMPROP-
ERLY INSTALLED AND OPERATING AP-
PLIANCE, VOIDING ITS WARRANTY. ANY

OXIDE POISONING.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to
the flu with headaches, dizziness and/or nau-
sea. If you have these signs, obtain fresh air
immediately. Turn off the gas supply to the
appliance and have it serviced by a qualified
professional, as it may not be operating
correctly.
WARNING: B-VENT APPLIANCES ARE
NOT DESIGNED TO OPERATE IN NEGA-
TIVELY PRESSURED ENVIRONMENTS
(PRESSURE WITHIN THE HOME IS LESS
THAN PRESSURES OUTSIDE). SIGNIFI-
CANT NEGATIVELY PRESSURED ENVI-
RONMENTS CAUSED BY WEATHER,
HOME DESIGN, OR OTHER DEVICES MAY
IMPACT THE OPERATION OF THESE AP-
PLIANCES. NEGATIVE PRESSURES MAY
RESULT IN POOR FLAME APPEARANCE,
SOOTING, DAMAGE TO PROPERTY AND/
OR SEVERE PERSONAL INJURY. DO NOT
OPERATE THESE APPLIANCES IN NEGA-
TIVELY PRESSURED ENVIRONMENTS.
WARNING: CHILDREN AND ADULTS
SHOULD BE ALERTED TO THE HAZARDS
OF HIGH SURFACE TEMPERATURES. USE
CAUTION AROUND THE APPLIANCE TO
AVOID BURNS OR CLOTHING IGNITION.
YOUNG CHILDREN SHOULD BE CARE-
FULLY SUPERVISED WHEN THEY ARE IN

OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation must be controlled through
a remotely located wall switch (factory-sup-
plied). Separate switches may provide inde-
pendent control for the remote controlled fire-
place operation (optional equipment).
Gas Control Compartment Access
See
Figure 1
for the location of the gas control
valve and piezo ignitor (millivolt units).
When the bottom edge of the access panel
swings out, cup it with the finger tips of both
hands. Lift with the finger tips, moving the panel
up and into the appliance. Pull the panel top edge
out from the appliance with the thumbs to re-
move it from the lower compartment opening.
Control Compartment Access - GHC-6500
Units
The GHC lower control compartment access is
provided by removing the four louvers. To
remove the louvers, pull them straight out from
the unit. To replace, tilt each of them with the
top edge over the top of each peg and snap the
lower edge to lock in place.
See Figure 3.

Control Compartment Access - GRD-6500
Series units
The lower control compartment access panel is
attached to each side of the fireplace by pins
that engage locking slots on the sides of the
panel
(Figure 2 )
. To remove the panel push in
on it’s top edge with both thumbs, one on each
end of the panel.

Operation of millivolt and electronic gas con-
trol systems are different. Before lighting and
operating your appliance determine if you
have a millivolt or electronic appliance. Milli-
volt appliances will be fitted with the gas
control valve shown in
Figure 4 .
Appliances
with electronic systems will be fitted with the
electronic valve shown in
Figure 5.
Familiar-
ize yourself with the differing controls for the
valve your appliance uses.
