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 an-
gling out of the firebox opening (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 20).
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 remote wall switch to main
power supply (Standard 120v household current).
4. Locate wall switch in a convenient location.
5. After wire connections are complete, replace refractory access
panel.

controls.
2. Disconnect wall switch wires from TH and TH/TP terminals
on control valve (see Figure 14).
3. Install remote receiver unit onto mounting bracket using the
two plastic mounting clips (see Figure 15).
Note: If any of the original wire as supplied must be replaced, use
18 AWG TYPE CL2 (UL) 105 C (25 ft. length MAXIMUM) or
equivalent.
