2.0 Operating Instructions

For units WITH factory installed rocker switch.

The ON/OFF rocker switch on the fireplace (located near the gas valve) must be in the “OFF” position for use with the WSK-MLT system. The ON/OFF rocker switch will NOT function with this device on Intellifire (IPI) models except during a power outage.

For units WITHOUT factory installed rocker switch.

The ON/OFF rocker switch now installed on the fireplace must be in the OFF position for use with the IPI or stand- ing pilot system. The ON/OFF rocker switch will only be used to control the fireplace in a no-power condition. For standing pilot systems use the rocker switch to turn the fireplace on and off. When power is restored switch the rocker switch to OFF. For IPI system refer to “Operation Under Battery Power” for instructions.

After all connections are made and the control box is grounded, plug power cord into the fireplace junction box. The wall switch will be functional at this time.

NOTE: The temperature displayed by the wall switch may take up to 30 minutes to stabilize on initial power-up.

NOTE: Check control box and assure switch is in the “OFF” position. This switch is only used on Intellifire (IPI) control systems under battery operation.
