Features
- 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.
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.
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.

Vent Type
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.

Modulating/Staging
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Review Posted 03/09/2020
I am a basic do-it-yourselfer. I needed this specific unit to replace a legacy unit that had served its purpose. Putting this in was a little bit of carpentry on the floor to match the openings, a crawl under the house to position the unit. An hour or two to replace and hook up new gas lines, vent and thermostat wire and presto it worked like a champ. And is still working flawlessly to keep the tenants warm and happy. Simple, dependable and just what the Doctor ordered on this side. Wish I could find more in other sizes. In our community these things are a staple in older homes. And it seems to put out a lot more heat than my geothermal and heat pump units.

Review Posted 12/18/2017
The unit is reasonably straight forward to install. The unit is well made. We encountered 1 major issue during installation. The accompanying manual is incorrect in terms of the electrical hookup. Took a picture of how it was connected and your tech support was able to quickly diagnose the issue. Tech support confirmed the manual was incorrect.
The 12 inch clearance below the unit requires removal of dirt if home is less than 4 feet off the ground.
