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 11/19/2022
I selected this heater out of a number of choices based on reviews and the promise of more heat output than other options, and after one fall/winter, this looks like it’s going to do great for my small cabin. I will definitely add a blower to help circulate, but very pleased with performance so far.

Shipping issue

Review Posted 02/20/2017
Have not used yet due to final construction needed but the shipping company put a forklift dent in the sheet metal. I did not return because it is cosmetic and this unit was needed for a disabled person. Please let your freight company know of my damage.

Review Posted 12/05/2016
Have had it up and running for about 4 days now, and have had no complaints. Using this for the main source of heat in a single wide trailer in the state of Maine. Got this for my sister and she called me last nite, temp was in the 20's outside and inside was 75 degrees, warmest she has ever had it in the cold weather since she has lived there for 30 years. Even one of her cats is not sleeping with them now, she is sleeping in the cat toy next to the furnace.
