Step 6. Connecting Gas Line –
Make gas line connections. All codes re-
quire a shut-off valve mounted in the supply
line. Figure 23 illustrates two methods for
connecting the gas supply. The flex-line
method utilizing the gas flex line provided
with the appliance is acceptable in the U.S.,
however, Canadian requirements vary de-
pending on locality. Installation must be in
compliance with local codes.
The millivolt and electronic control valve have
" (10 mm) NPT thread inlet ports.
WARNING: TO PREVENT DAMAGE TO
THE VALVE AND OTHER ATTACHED COM-
PONENTS, HOLD VALVE FIRMLY IN
PLACE WHILE TIGHTENING FITTINGS
USED IN THE NEXT STEP.
The gas control valve is located in the lower
control compartment. See Figure 24. To ac-
cess the valve see page 9, the Control Com-
partment Access Section.

Secure all joints tightly using appropriate
tools and sealing compounds (ensure pro-
pane resistant compounds are used in pro-
pane applications).
Turn on gas supply and test for gas leaks using
a soapy water solution. Never use an open
flame to check for leaks.
A. Mix a 50% dish soap, 50% water solution.
B. Light the appliance (refer to the lighting
instructions provided in the Homeowner's Care
and Operation Instructions).
C. Brush all joints and connections with the
soapy water solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the "OFF" posi-
tion. Either tighten or refasten the leaking
connection and retest as described above.
D. When the gas lines are tested and leak free,
observe the individual tongues of flame on the
burner. Make sure all ports are open and
producing flame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.

Step 7. Install Optional Outside
Combustion Air Kit
When outside combustion air is desired, Len-
nox' Model FOAK-4 or Model FOAK-4LD com-
bustion air kit should be used. Refer to the
installation instructions packed with the air kit
for specific installation information. The outside
air kit must be installed before the appliance is
framed and enclosed in the finished walls.
The control lever, located on the left side of the
appliance front opening, controls the entrance
of combustion air from the outside. See Figure
25 for 5500 series units, Figure 26 for GHC-
6500 series units or Figure 27 for GRD-6500
series units. The 6500 series units have a cover
over the control lever fastened by one screw.
Remove the screw and then the cover and
discard them.
If an optional "All-Glass" enclosure panel is to
be installed on the 6500 Series appliances, an
extension bar must be attached to the actuator
lever as illustrated in Figures 26 and 27 . Both
versions of the actuator lever extension bar are
packaged with the glass enclosure panel.
