Step 4. FIELD WIRING
Refer to Section A for millivolt appliances and
Section B for electronic appliances. The gas
valve is set in place and pre-wired at the
factory on both models.
A. SIT and Honeywell Millivolt Wiring
(See Figure 46) –
1. Select any of the following optional con-
trols: appliance-mounted (rocker switch) or
wall-mounted switch, thermostat, or one of
the optional remote control kits. If appliance-
mounted ON/OFF control is selected mount it
in the gas valve mounting bracket.
2. If wall-mounted ON/OFF control or ther-
mostat is selected mount it in a convenient
location on a wall near the fireplace.
3. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 conductor wire
supplied with the unit . Caution: do not connect the
optional wall switch to a 120V power supply.
4. Alternatively, the appliance may be operated
without the use of the controls indicated in step 1,
solely by manipulating the gas valve control knob. In
order to use this method, twist the free ends of the two
conductor wire (located inside the bottom compart-
ment of the unit) together as shown in Figure 46 .
Note: The supplied 15 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 inside the bottom compartment of the unit.

If any of the original wire as supplied must be replaced,
it must be replaced with Type AWM105 C – 18 GA. wire.

B. Electronic Wiring (See figure 48 or 49) –
Note: The electronic appliance must be con-
nected to the main power supply.
A junction box is located at the rear of the control
compartment on either side of the cabinet. The
junction box on the right side contains a factory
installed and wired outlet box (duplex recep-
tacle). Also, an optional field-provided junction
box with receptacle may be installed at the front
of the control compartment on either side of the
cabinet. See Figure 47. It will be held in place
by a conduit fitting and locknut (field-provided).

Figure 47
1. Route a 3-wire 120Vac 60Hz 1ph power
supply to the appliance junction box.
2. If the factory-provided outlet/junction box
at the right rear of the fireplace is being used,
remove the outlet box from the junction box by
removing two screws.
3. Connect the power supply wires (includ-
ing the ground supply wire) as shown in
Figures 48or 49. (If the field-provided J-box/
outlet box is being used, all of the outlet box
wiring must be field-provided.)
4. Locate and install a low voltage (24V) wall-
mounted switch or thermostat (both field-
provided) in the desired location.
5. Connect the low voltage wire (located in-
side the bottom compartment of the unit) to
the wall-mounted switch or thermostat.
Note: The supplied 15 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 inside the bottom compartment of the unit.
6. Insert the control circuit plug into the
unswitched receptacle of the outlet box.
7. After wiring is complete, mount the outlet
box to the J-Box.
Note: The gas valve-mounted ON/OFF switch is shown
in Figure 48 or 49. It is integral with the gas valve
and should be set to the ON position.

BLOWER KIT
FBK-100, FBK-200 and FBK250 Kits
(See Figure 48 for FBK-100, FBK-200 and
Figure 49 for FBK-250 wiring) -
An electrical outlet box (receptacle) is factory -
Figure 46
provided for the installation of the FBK-100, FBK-
200 and FBK-250 forced air blower kits. (An
optional field-provided outletbox/J-Box may also
be used. Electrical power must be connected to
either of these receptacles in order to operate these
blowers. Install the blower kits according to the
installation instructions provided with the kits.
Note: The tab connecting the receptacles of the
outlet box must be broken in FBK-100 and FBK-
200 blower kit applications.
IMPORTANT: Ground supply wire must be
connected to the green wire attached to the
outlet receptacle's green ground screw. See
Figure 48 or 49 . Failure to do so will result in
a potential safety hazard. The appliance
must be electrically grounded in accordance
with local codes or, in the absence of local
codes, the National Electrical Code, ANSI/
NFPA 70-(latest edition). (In Canada, the
current CSA C22-1 Canadian Electrical Code.)
