The gas control valve is located in the lower
control compartment. To access the valve
open the lower control compartment door
(
Figure 9 ).
The regulator has a 3/8" NPT thread inlet port
and is fitted with a 3" (76 mm) long nipple,
³⁄₈"
NPT on both ends. Plan the connections ac-
cordingly.
We recommend that the gas line be routed for
the right side of the appliance to ensure ad-
equate access to the rear lower compartment
for installation and servicing of the optional
FAB-1100 blower.

Secure all joints tightly using appropriate
tools and sealing compounds (ensure pro-
pane resistant compounds are used in
propane applications).
Turn on gas supply and test for gas leaks,
using a gas leak test solution (also referred to
as bubble leak solution).
Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time. Never
use an open flame to check for leaks.

Step 2. Route a 1/2" (13 mm) gas line along the
left or right side framing (
Figure 7 ).
All appliances have a 3" long 3/8" NPT nipple
installed at the regulator. To quickly and easily
complete the gas line routing, use the gas flex
line kit, Model GFLV.
Step 3. Position appliance into prepared fram-
ing, secure with 6d nails at the nailing flange
along each side.
Step 4. Connecting Gas Line – Make gas line
connections. All codes require a shut-off valve
mounted in the supply line.
Figure 8 illustrates
two methods for connecting the gas supply.
Installation methods and materials must be in
compliance with local codes.
