NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Millivolt appliances may be fitted at time of
manufacture with either a Robertshaw millivolt
gas control valve or Robertshaw electronic gas
control valve. Both valves have been tested
with and approved for use with these appli-
ances and are listed accordingly.
A ¹⁄₈" NPT test gage connection is provided on
either gas control valve adjacent to the outlet to
the main burner.
Minimum inlet gas pressure to the appliance is
4.5 inches water column (8.55 MmHg) for
natural gas and 11 inches water column (20.55
MmHg) for propane for the purpose of input
adjustment.
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 IMPROPERLY
INSTALLED AND OPERATING APPLI-
ANCE, VOIDING ITS WARRANTY. ANY
CHANGE TO THIS APPLIANCE AND/OR
ITS OPERATING CONTROLS IS DANGER-
OUS. IMPROPER INSTALLATION OR USE
OF THIS APPLIANCE CAN CAUSE SERI-
OUS INJURY OR DEATH FORM FIRE,
BURNS, EXPLOSION OR CARBON MON-
OXIDE POISONING.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to
the flu with headaches, dizziness and/or
nausea. 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 op-
erating correctly.
WARNING: B-VENT APPLIANCES ARE NOT
DESIGNED TO OPERATE IN NEGATIVELY
PRESSURED ENVIRONMENTS (PRESSURE
WITHIN THE HOME IS LESS THAN PRES-
SURES OUTSIDE). SIGNIFICANT NEGA-
TIVELY PRESSURED ENVIRONMENTS
CAUSED BY WEATHER, HOME DESIGN,
OR OTHER DEVICES MAY IMPACT THE
OPERATION OF THESE APPLIANCES.
NEGATIVE PRESSURES MAY RESULT IN
POOR FLAME APPEARANCE, SOOTING,
DAMAGE TO PROPERTY AND/OR SEVERE
PERSONAL INJURY. DO NOT OPERATE
THESE APPLIANCES IN NEGATIVELY PRES-
SURED 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
THE SAME ROOM AS THE APPLIANCE.
WARNING: DO NOT PLACE CLOTHING
OR OTHER FLAMMABLE MATERIALS
ON OR NEAR THIS APPLIANCE.
AVERTISSEMENT: SURVEILLER LES

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 Controls/Control Compartment
Access
See Figure 1 for the location of the gas control
valve and piezo ignitor (millivolt units).
Control Compartment Access - GRD-5500
Units
The lower control compartment access panel
has been designed to cover the control com-
partment from view. Lighting instructions are
displayed on the back side of the cover for easy
reference. To attach the panel to the appliance,
hook both ends of the panel over the two
brackets mounted on each side of the front
combustion opening. The cover should hang
from the brackets with the flared edge at the
bottom allowing for a small air gap between the
cover and the appliance. To remove, lift the
panel and pull away from the unit.
Control Compartment Access - GHC-5500 Units
The GHC lower control compartment access is
provided by removing the three 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.
