Optional On/Off Device - Empire Heating Systems GWT-50W-2 Instructions D'installation Et Manuel Du Propriétaire

OPTIONAL ON/OFF DEVICE(SG MODELS)
CAUTION — Do not run wire behind flanges of Header Plate or in
any location where it might be damaged.
Millivolt wall on/off device is 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 (Figure 7)
A millivolt meter is required to check the system. Millivolt readings
should be:
• Across the thermopile terminals, 400-450 millivolts with heater
OFF.
• Across the thermopile terminals, 150-250 millivolts with heater
ON.
• Across the heater wires at the valve, less than 30 millivolts with
heater ON.
To conserve Gas: Turn off pilot when heater is not in use.
