Features

    Safety is no worry with this furnace, having a matchless pilot igniter and sealed combustion chamber requiring no inside air. Whether recessed into the wall or surface mounted, the soft-white powder coated finish provides a discrete durable finish that blends into any home's decor.
  • Sealed Combustion
  • Rather than using indoor air to fuel combustion, the Williams direct vent pulls intake air directly from the outdoors. This means the heat your furnace generates isn't fed back into the system, maximizing efficiency.
  • Counterflow Blower System
  • The Forsaire furnace has a counterflow blower system that takes air from the ceiling and blows the warm air at the floor. This allows for the heat to be evenly distributed throughout the room.
  • 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 Forsaire furnaces. This turns off the unit in case the vent is blocked, protecting your family from carbon monoxide and fires.
  • Product Includes
  • All Vent Materials Needed for a 9" Thick Wall
  • Product Note
    A thermostat does not come included with this unit and is required. The Williams P322016 thermostat is compatible and can be found under the "Accessories" tab. Alternatively, any standard millivolt thermostat can be used.

Nice Furnace!

Review Posted 05/20/2021 
Replacing a 60 year old propane furnace in our 110 year cottage is a welcome luxury . We have not had a problem with the Williams wall furnace. It is really nice to dial up the thermostat and have this wall furnace do its job so well. Thanks for a great product Williams!

Three way diffuser Excellent Accessory
By Orrie S.

Purchased 03/19/2020 | 
Review Posted 04/10/2020 
This unit is made of quality metal. Easily snaps in place. It sends heat to the right and left and in the front. I received it very fast the fastest that I have received any ordered item. The price was competitive. And it was in stock most places had to order it before I could get it.
