Features
- Space-Saving Size
- The direct vent model is a low-profile furnace that can fit in just about any space. Having a unique wall mount design, this furnace requires no floor space.
- No Electricity Needed
- During power outages, you have a lot to worry about, but your furnace won't be one. The Direct-Vent furnace requires no electricity for operation.
- 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.
- Easy Installation
- The Williams Direct Vent furnace mounts directly on the outside-facing wall. Venting is accomplished through a single 9" opening to the outdoors and vent materials that will accommodate most installations are included.
- Product Includes
- Williams Direct-Vent Furnace
- All Vent Materials Needed for a 9" Thick Wall
Williams' Direct-Vent Wall Furnace makes heating any home easy. The Direct-Vent model is attractive and economical with a slim design taking up minimal space. Safety is no worry with this furnace, having a matchless pilot igniter and sealed combustion chamber requiring no inside air. The soft white, scratch-resistant coating can blend in nicely with any homes decor.
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.

Review Posted 12/23/2024
This heater works well! Easy to install, good directions. I've only been using it for a month now and I am very satisfied so far. The only thing that needs to be added to this heater is Handles on the cover.

These Williams furnaces are awesome.
They are extremely simple to install. Instructions are very good.
And they work flawlessly.
This is the third one I have installed in one of my living spaces and wouldn’t hesitate recommending this to anybody.

I didn't actually run the stove yet since it is only July
I definitely like the look of it.
It was very easy to install.
I will give you more input in the fall.

Review Posted 02/03/2022
Just hooked up for 864ft loft in New Hampshire winter excellent heating, even without blower. Still a slight smell after 48 hours, but will probably burn off.
A bit noisy, though.

Wall Furnace Heater
By Billie S.
Paso Robles, California
Purchased 10/06/2021 |
Review Posted 12/01/2021
We love it… it’s quiet and beautiful…the only issue is the vets are not adjustable, so the airflow is directly radiating towards ceiling which heats up the upstairs rooms too much. Adjustable vent direction would enable us to direct the airflow in different directions.
