NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

CAUTION

Ensure that wires are positioned
away from hot surfaces and sharp
edges.

CAUTION

Do not connect the optional wall
switch for burner operation to a
120 Volt AC power supply.

CAUTION

Label all wires prior to disconnection
when servicing controls. Wiring
errors can cause improper and dan-
gerous appliance operation.

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 43) –

1. Select any of the following optional controls:

appliance-mounted (rocker switch) or wall-
mounted switch, wall thermostat, or the
standard or deluxe remote control kits. If ap-
pliance-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 fi replace.

Figure 43 -

SIT & HONEYWELL Millivolt Wiring Diagram

3. Connect the power supply wires (including

the ground supply wire) as shown in Figures
44 & 45. (If the fi eld-provided J-box/outlet
box is being used, all of the outlet box wiring
must be fi eld-provided).

4. Locate and install a low voltage (24V) wall-

mounted switch or thermostat (both fi eld-
provided)in the desired location.

5. Connect the low voltage wire, located inside

the control compartment, 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 control
compartment.

6. Insert the control circuit plug into the un-

switched 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 45. It is integral with the gas
valve and should be set to the ON position.

Step 5.

WIRING - OPTIONAL FORCED AIR

BLOWER KIT

FBK-100, FBK-200 and FBK250 Kits
(See Figure 45) -

An electrical outlet box (receptacle) is factory
-provided for the installation of the FBK-100,
FBK-200 and FBK-250 forced air blower kits.
(An optional fi eld-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.

3. Wire the control 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
(which would otherwise go to the standard
ON/OFF switch or Optional Switch) together
as shown in Figure 43.

Note: Wire is located inside the control

compartment

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 control
compartment.

B. Electronic Wiring (See Figure 45) –
Note: The electronic appliance must be con-
nected to the main power supply.

The junction box is located on the right side of
the appliance. It contains a factory installed and
wired outlet box (duplex receptacle). Also, an
optional fi eld-provided junction box with recep-
tacle may be installed at the front of the control
compartment on either side of the cabinet. See
Figure 44. It will be held in place by a conduit
fi tting and locknut (fi eld-provided).

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 fi replace is being used,
remove the outlet box from the junction box
by removing two screws.
