actuate the spring-loaded magnetic catches securing the panel. First, depress the outer top right corner of the panel until the catch "pops" the door free. Then, gently pull the door forward until the left top corner "pops" free, allowing the panel to swing out and down to open.

On millivolt systems, the piezo igniter, HI/LO flame adjustment knob, and pilot and main gas OFF/ON control knob are located below the glass panel enclosure. The gas valve for electronic systems is also located below the glass enclosure panel. See Figure 1.

To ease door closure, depress the catches to place them in their retracted position, then close the door.

Millivolt appliances are fitted with an OFF/ON Rocker Switch located behind the control compartment access panel, below the appli- ance front glass enclosure panel (see Figure 1 for location). Once the pilot is lit, the OFF/ON rocker switch will control the appliance OFF/ON burner operation. To operate: Toggle the switch between its ON and OFF positions.

If your millivolt appliance is equipped with an optional remote switch kit (wall switch, remote control or wall thermostat) and the pilot is lit, the appliance main burner may be turned on and off using the optional switch. When using an optional remote switch, turn off the standard OFF/ON switch.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

 

Note: The piezo igniter and burner

glass panel (see Figure 1).

Note: To prevent excessive resistance in burner circuit (which can cause burner operation prob- lems), only one burner control switch should be wired to valve. Therefore, if an optional control switch is installed, the standard Off/On switch and wires should be removed.
