1.Route a 3-wire 120V 60Hz power supply line to the appliance junction box wires and ground

(Figures 13 ).

2.After wiring is complete, replace the appli- ance junction box cover and secure with the hex head screws previously removed.

Step 6. Connecting Gas Line – Make gas line connections. All codes require a shut-off valve mounted in the supply line. Figure 16 on page 9 illustrates the method for con- necting the gas supply. The flex-line method utilizing the gas flex line provided with the appliance is acceptable in the U.S., how- ever, Canadian requirements vary depend- ing on locality. Installation must be in com- pliance with local codes.

The gas control valve is located in the lower control compartment. To access the valve remove the refractory access panel and set aside (Figure 14 ). The control valve has a 3/8" (10 mm) NPT thread inlet port.

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 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.

A. Light the appliance (refer to the lighting instructions label in the control compartment or in the Homeowner's Care and Operation Instructions).

B. Brush all joints and connections with the gas leak test 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.

C. When the gas lines are tested and leak free, be sure to rinse off the leak testing solution.

Step 7. Optional Outside Air Kits – Combus- tion (outside make-up air) kits, Model FOAK-4 or FAOK-4LD, may used with these appli- ances. Refer to the installation instructions packaged with the air kits for specific installa- tion information. The outside air kit must be installed before the fireplace is framed and enclosed in the finished wall.

Outside air drawn into the fireplace supplies air to the fire for combustion. Only one com- bustion air duct on the right side of the fire- place is necessary if installed.

If additional length of duct is necessary, pur- chase locally available U.L. Class 0 or Class 1 metallic ducting. The duct may extend up to 50' (15.24 m) in any direction.

There is one hand operated air gate shut-off, for utside make-up air, located at the right side of the fireplace opening behind the screen. To open, lift and pull the handle out. The combus- tion air damper should be open when the fireplace is in use and, to prevent outside air from entering your home, fully closed when the fireplace is not in operation.
