VENTING INSTALLATION

Continued

CHECKING FOR PROPER VENTING

After completing and checking the electrical, gas and vent connections, follow the lighting instructions and allow the main burner to run for approximately 5 minutes. Hold a lighted match or cigarette near the top edge of the fireplace opening and play it along the entire length of the opening (see Figure 12). Proper venting should tend to draw the flame or smoke into the appliance. Improper venting or escaping of spillage of burned gas, is indicated when the match flickers or goes out. Smoke from a cigarette will also tend to disperse away from the appliance.

If the appliance is found to be improperly venting, shut it off and notify your installer or a qualified service agency to inspect the venting system.

If the appliance shouldshutdown,contactaquali- fied installer, service agency or your gas supplier to have the vent inspected before operating.

Check this area along the entire top edge of the fireplace opening.

Smoke or flame should be drawn into the appliance opening.

WALL SWITCH INSTALLATION

The installation of a wall switch allows you to activate the gas control valve without the normal household electricity since the valve operates on millivolt current supplied by the heat generated by the thermopile. To install the wall switch:

1.Remove the front refractory access panel by lifting up and angling out of the firebox open- ing (see Figure 13).

2.Use wire and connectors provided. Attach red wire to terminal marked TH/TP on control valve. Attach white wire to blade connector on open end of safety circuit wiring (see Wiring Diagram, page 22).

Note: If any of the original wire from the unit control must be replaced, use the same type or a higher rated wire (25 ft. maximum length).

WARNING: Do not wire re- mote wall switch to main power supply (Standard 120v house- hold current).

3.Locate wall switch in a convenient location.

4.After wire connections are complete, replace refractory access panel.
