Operation Under Battery Power

A switch on the control box allows for battery power under no-power conditions (see Figure 12.9). By control- ling the power supply with this switch, the batteries are supplying power only when needed, thus extending bat- tery life. The switch also provides a convenient means for switching to battery power should there be a loss of 110 VAC power to the control box.

•In the event of a power failure, switch the battery operation switch to the “Battery ON” position.

•The fireplace can now be turned on and off with the ON/OFF rocker switch located near the gas valve.

•The wall switch functions will not operate under battery power.

•Under battery control the only available function is flame “ON” and “OFF” in the high position.

•To maximize battery life, and to restore full function capability of the wall switch, flip switch to “OFF” position after 120 VAC power is restored.
