The Monterey Home Wall furnace series are value-for-your-money-priced models featuring energy and money-saving operating costs. Easily recessord or surface-mounted options are great in homes, schools, cabins, apartments, offices, and shops. Heating rooms individually allows comfort in areas being used while saving fuel cost in unused areas. Great during power outages, no electricity required. No need to purchase a thermostat, as these units are equiped with a self-generating millivolt thermostat that may be wall-mounted or cabinet-mounted.

In order to operate on LP (liquid propane), the Williams 8909 LP Conversion Kit must be purchased seperately.

Important Safety Notice:  The surface temperature of wall furnaces can exceed 200 degrees Fahrenheit. Avoid touching the furnace while it is in use. If children will be present, provide a physical barrier to prevent accidental contact with the furnace. Please read this additional Important Safety Notice.
