On/Off Device - Empire GWT-25W-2 Instrucciones De Instalación Y Manual Del Propietario

CAUTION — Do not run wire behind flanges of Header Plate or in
any location where it might be damaged.
Millivolt wall on/off devices are specially designed for use on self-
generating systems. They should never be used on line or low
voltage A.C. circuits.
Installing the ON/OFF Device
To install an ON/OFF device (such as a wall switch, remote, toggle
switch,or thermostat), remove the wire nut from the two wires from
the valve. Run additional wire from the valve wires to the ON/OFF
device. Install the ON/OFF device in the same room as the furnace
following the installation instructions supplied with it. In the absence
of instructions, install the ON/OFF device 4 to 5 feet above the floor
on an interior wall not affected by another heating source (i.e. stove
or water heater) or the temperature of an adjoining room..
Proper operation depends on a good pilot flame. The flame must
cover the top of the thermopile. Cleaning of the pilot orifice and
burner may be required due to spiders.
System Check (Figure7)
A millivolt meter is required to check the system. The millivolt
readings should be:
• Across the thermopile terminals, 400-450 millivolts with the
heater OFF.
• Across the thermopile terminals, 150-250 millivolts with the
heater ON.
• Across the wires at the valve, less than 30 millivolts with the
heater ON.
To conserve Gas: Turn off pilot when heater is not in use.
