Millivolt Appliances - Appliances with Millivolt systems will be fitted with the gas control valve shown in Figure 3.

Electronic Appliances - Appliances with electronic systems will be fitted with the electronic valve shown in Figure 4.

Millivolt Appliances - To light millivolt ap- pliances refer to Figure 2. Detailed lighting instructions are found on Pages 18 & 19 . Mil- livolt appliance lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.

Once the pilot is lit, the main burner may be turned ON and OFF using wall switch, remote control, optional on unit rocker switch (FRS), or wall thermostat. 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, rocker switch, or wall thermostat) and the pilot is lit, the appliance main burner may be turned on and off using the optional switch.

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.
