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.
FIGURE 1
If this is not possible, the water supply to the house should
be shut off and the pipes should be drained. This will pre-
vent problems associated with a NO HEAT condition (fro-
zen pipes, etc.)
