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 operation 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 associated with a NO HEAT condition (frozen pipes, etc.)
WARNING
Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at the
disconnect switch.
