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.)
