Control Compartment Access - GRD Units
5500 Series units
The lower control compartment access panel
has been designed to cover the control com-
partment from view. 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.
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 14 )
. To remove the panel push in
on it’s top edge with both thumbs, one on each
end of the panel. 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 remove it from the lower com-
partment opening.
Control Compartment Access - GHC Units
The GHC lower control compartment access is
provided by removing the three louvers (5500
series units) or four louvers (6500 series units).
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 15.

Note: The supplied 18 feet of 2 conductor wire
has one end of each conductor connected to the
gas valve circuit and the other end of each
conductor placed loose on top of the unit.
CAUTION: DO NOT WIRE THE MILLIVOLT RE-
MOTE WALL SWITCH TO THE MAIN POWER

3 - Install the provided “J” box plate on the “J” box
within the control compartment using the screw
and washer provided with the plate.
4 - Refer to
Figure 17 and 18
and the installa-
tion instructions provided with the forced
air kit(s) for blower connections to the
appliance recepacle and ground.
5 - Locate and install the millivolt wall switch
(supplied) in a desired location and con-
nect it to the millivolt circuit using the 18 ft
of 2 conductor wire supplied with the unit
(See Figure 16).
Note: The supplied 18 feet of 2 conductor
wire has one end of each conductor con-
nected to the gas valve circuit and the
other end of each conductor placed loose
on top of the unit.
6 - After wiring is complete, replace the appli-
ance junction box cover into the side ac-
cess opening, from which it was removed,
and secure with the hex head screw previ-
ously removed.
Millivolt Wiring (Without Forced Air Kit Usage) –
The control tray has been set in place and has
been pre-wired at the factory. All that is re-
quired, regarding wiring, is to locate and install
the wall switch (supplied) in a desired location
and connect it to the millivolt circuit using the
18 ft of 2 conductor wire supplied with the unit
(Figure 16 ).
Millivolt Wiring (With Forced Air Kit Usage) –
GHC-5500 series models may use the optional
FAB-1500 or FAB-1600 Forced Air Kit; GHC-
6500 the FAB-1600 Kit.
If an optional forced air kit is to be installed now
or sometime in the future, the appliance must be
connected to the main power supply at this time.
1 - Remove the junction box cover from the
outside right bottom corner of the unit by
removing the hex head screw. The junction
box cover has a ⁷⁄₈ in. (22 mm) knockout
hole for a conduit bushing.
2 - Route a 3 wire 120V 60Hz power supply
line through a wall switch to the junction
box and connect the ground wire to the
junction box ground screw, and the black
and white supply wires to the appliance
recptacle as shown in
Figure 17.
