Millivolt wall thermostats are specially designed for use on self-
generating systems. They should never be used on line or low
voltage A.C. circuits.
Interior Wall — The thermostat should be installed on an inside
wall away from the furnace but in the same room.
Note: Use 16 gauge wire to prevent excessive loss of millivolts.
