    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.
  • 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
  • Product Note
    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.

Can the exhaust vent use a 90 degree elbow?
Ron H. 
from Nevada 
July 26, 2016
Answer
Williams Direct-Vent furnaces are designed to vent directly through the wall they are installed on. No elbows or other fittings are available or permitted. I have attached a link for the install manual for reference below:
