An electrical receptacle is provided for the
installation of the FBK-100, FBK-200 and FBK-
250 forced air blower kits. Electrical power
must be connected to this receptacle in order
to operate these blowers. Install the blower
kits according to the installation instructions
provided with the kits.

Step 7. CONNECTING GAS LINE

Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure
55 illustrates two methods for connecting the
gas supply. The flex-line method is acceptable
in the U.S., however, Canadian requirements
vary depending on locality. Installation must
be in compliance with local codes. A sediment
trap is recommended in the gas piping within
the home to prevent moisture and debris in the
line from damaging the valve.
These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the direct vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. The flex line
is rated for both natural and propane gas. A
manual shut off valve is also provided with
the flex line.
The gas control valve is located in the lower
control compartment.
To access the valve open the lower control
compartment door (see Figure 56 ) by pushing
in the right top corner of the door. (The door
is hinged at the bottom.) Remove the bottom
compartment door by sliding the hinge pin,
located at the door's left side, to the right until
it disengages from the left corner post hole.
Pull the door diagonally to the left, away from
the fireplace.
The lower control compartment door on the
side opposite the valve lifts on and off.
The millivolt control valve has a 3/8"
(10 mm) NPT thread inlet port. The electronic
control valve has a 1/2" (13 mm) NPT thread
inlet port and is fitted with a 1/2" x 3/8" (13 mm x
10 mm) NPT fitting.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane
applications).
All codes require a shut-off valve mounted
in the supply line. The orientation of the
shut-off valve should face the front. Figure
55 illustrates two methods for connecting the
gas supply. A sediment Trap is recommended
to prevent moisture and debris in the gas line
for damaging the valve.
