Remove the front refractory access panel by lifting up andangling out of the firebox opening (see Figure 13) to exposecontrols.2. Disconnect wall switch wires from TH and TH/TP terminalson control valve (see Figure 14).3. Install remote receiver unit onto mounting bracket using thetwo plastic mounting clips (see Figure 15).Figure 15 - Installing Remote Receiver (Shown from Rear ofMounting Bracket)INSTALLATIONWARNING: Do not wire remote wall switch to mainpower supply (Standard 120v household current).WALL SWITCH INSTALLATIONThe installation of a wall switch allows you to activate the gascontrol valve without the normal household electricity since thevalve operates on millivolt current supplied by the heat generated bythe 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 terminalmarked TH/TP on control valve. Attach white wire to bladeconnector on open end of safety circuit wiring (see WiringDiagram, 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).ReceiverMountingBracketPlasticMountingClipsFigure 13 - Removing Front Refractory Access Panel4.
