MILLIVOLT OPERATING INSTRUCTIONS

VFCR-25 ON/OFF/REMOTE Switch

VFCR-25 is equipped with an ON/OFF/REMOTE switch which is located on the wiring chase. A wire harness is attached to the ON/OFF/REMOTE switch. The brown, black and green (wires) female push-ons attach to the ON/OFF/REMOTE switch. At the opposite end of the wire harness, the black and green (wires) female push-ons attach to the gas valve. An additional brown wire and the black/red wire, which are stripped and bare, will attach to the 750 millivolt wall thermostat accessory, or, to one of the other accessories that can be purchased for use with your log set.

Operation of ON/OFF/REMOTE Switch with no Accessories To ignite main burner, turn the control knob on the gas valve from the PILOT position to the ON position. Turn the ON/OFF/ REMOTE switch from the OFF position to the ON position. The additional brown wire and black/red wire, which are stripped and bare are not used.

Connect the brown and black/red, stripped and bare, wires on the ON/OFF/REMOTEswitchwireharnesstothewallthermostat.Turn the ON/OFF/REMOTE switch on the valve cover to the REMOTE position. Set the wall thermostat to the desired temperature.

It is important to use wire of a gauge proper for the length of the wire:

RECOMMENDED WIRE GAUGES

Maximum	Wire
Length	Gauge
1' to 10'	18
10' to 25'	16
25' to 35'	14

750 Millivolt System

When you ignite the pilot, the thermocouple produces millivolts (electrical current) which energizes the magnet in the gas valve. After 30 seconds to 1 minute time period you can release the gas control knob and the pilot will stay ON. Allow your pilot flame to operate an additional one (1) to two (2) minutes before you turn the gas control knob from the PILOT position to the ON position. This time period allows the millivolts (electrical current) to build-up to a sufficient level allowing the gas control to operate properly.

Wall Switch, FWS-1

Connect the brown and black/red, stripped and bare, wires on the ON/OFF/REMOTE switch wire harness to the wall switch. Turn the ON/OFF/REMOTE switch on the valve cover to the REMOTE position. Pivot the rocker switch on the FWS-1 to the ON position.
