Overview for Williams 4505622A

The Williams floor furnace takes up no above-the-floor space and effectively circulates warm air without the aid of a blower. The floor furnaces are fitted with an automatic floor register grille temperature control and a nonelectric pilot to make sure you have continuous heat even during power outages. Williams floor furnaces circulate heat through natural convection and are the perfect choice for homes with limited space.
  • No Electricity Needed
  • During power outages, you have a lot to worry about, but your furnace won't be an issue. The floor furnace requires no electricity for operation.
  • Safe Pilot Ignition
  • With matchless pilot ignition, the guess work is taken out of lighting the furnace. By sealing the pilot and igniter away from dirt and debris, the electronic igniter lights the furnace safely and reliably.
  • Vent Limit Safety Switch
  • The vent limit safety switch is equipped on all floor furnaces. This turns off the unit in case the vent is blocked, protecting your family from carbon monoxide and fires.
  • Easy Servicing
  • The Williams floor furnaces have a removable combustion chamber that lifts out for easy servicing.
  • Product Note
    The Williams floor furnace is designed as a replacement for your existing floor furnace. A thermostat does not come included with this unit. The Williams P322016 thermostat is compatible and can be found under the "Accessories" tab. Alternatively, any standard millivolt thermostat can be used.
