    Williams High-Efficiency Direct-Vent Furnaces are a low-profile furnace that needs just minutes to warm up any room. Needing no outside air, this Williams furnace is perfect for safe operation while adding comfort to any room or space. Styled with a durable white finish, this furnace can look great in just about any room.
  • 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.
  • Electric Ignition
  • It can be a hassle to light a pilot with a match. More importantly, it can also be dangerous. This is why the Williams 1773511 uses an electric ignition, to make lighting your furnace as easy as possible.
  • Sealed Combustion
  • Rather than using indoor air to fuel combustion, the Williams 1773511 pulls intake air directly from the outdoors. This means the heat your furnace generates isn't fed back into the system, maximizing efficiency.
  • Year Round Comfort
  • A two-speed recirculating fan takes cool air off the ground and recirculates it back in to the room.
  • Programmable Timer
  • The High-Efficiency Direct-Vent furnaces comes standard with a programmable thermostat which allows for precise operating and timing control.
  • 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
  • Built-In Thermostat
  • All Vent Materials Needed for a 9" Thick Wall
