NOTE: This manual is the property of the homeowner
and must be left with the equipment user.
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.).
