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 ³⁄₈" (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

25for 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.
