Notice to Homeowner
This furnace is equipped with safety devices that protect

eration must be checked periodically. If this is not possible,
the water supply to the house should be shut off and the
pipes should be drained. This will prevent problems associ-
ated with a NO HEAT condition (frozen pipes, etc.)

nance, turn the electrical power to unit OFF at the
disconnect switch.
