Notice to Homeowner
This furnace is equipped with safety devices that protect
you and your property. If one or more of these devices is
activated, furnace operation will stop. If your home is left
unattended for an extended period of time, equipment op-
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.)
CAUTION
Before attempting to perform any service or mainte-
nance, turn the electrical power to unit OFF at the
disconnect switch.
CAUTION
As with any mechanical equipment, personal injury
can result from contact with sharp sheet metal
edges. Be careful when you handle this equipment.
