Features
- Space-Saving Size
- The High-Efficiency 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 and all models are equipped with a self-generating millivolt thermostat.
- Sealed Combustion
- Rather than using indoor air to fuel combustion, the Williams 0743511 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 High-Efficiency LP Direct-Vent Furnace
- All Vent Materials Needed for a 9" Thick Wall
Williams High-Efficiency Direct-Vent Furnaces are a low-profile solution that need just minutes to warm up any room. Direct vent operation means that inside air is not needed for combustion, so your warm air stays inside where it belongs. With a clean, durable white finish and space-saving wall mounted design, the Williams High-Efficiency Direct-Vent Furnace is a perfect heating option in almost any room.

Well Crafted Product, Couldn't Be More Impressed
By San J

Purchased 10/13/2020 |
Review Posted 11/06/2020
Just had the Williams Direct-vent 8,000BTU Propane Furnace installed in my "she-shed" and couldn't be more impressed.
Pro: -product includes ALL vent parts to install it in wall that is 5" or wider. Thin wall collar kit is only $25.00 more.
- cover shape is visually pleasing and not boxy - feels like less space used than boxy types.
- 1/4" space from wall vs. other products that require 3" of space from wall!
- even when on HIGH, the white metal cover is quite cool to the touch, great for a tiny space
Only small Con: no thermostat -only Lo to Hi knob. I'll mark other spots along arrow and use a few wall thermometers to find see what level matches temperature.

Compact and seem to be easily installed by contractor. Weather has not been cold, so not sure if full winter temps will be handled yet. But first impression is positive!
