CHECKING FOR PROPER VENTING
After completing and checking electrical,
gas and vent connections, follow the lighting
instructions and allow main burner to run
for approximately 5 minutes. Hold a lighted
match or cigarette near the top edge of fire-
place opening and play it along entire length
of 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 appliance is found to be improperly vent-
ing, shut it off and notify your installer or a
qualified service agency to inspect the vent-
ing system.

NOTICE: This appliance is
equipped with a vent safety
shutoff switch which will shut
down the appliance in the case
of a venting problem. Do not
bypass the vent safety switch. If
the appliance should shut down,
contact a qualified installer, ser

WALL SWITCH INSTALLATION
The installation of a wall switch allows you to
activate the gas control valve without normal
household electricity since valve operates on
millivolt current supplied by heat generated by
the thermopile. To install wall switch:
1. Remove front refractory access panel by
lifting up and angling out of 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 unit con-
trol 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.
