WILLIAMS-FURNACE-17735
Williams Not Quite Winter Warm Up
​This direct-vent wall furnace by Williams Furnace Company is a highly efficient indoor heating unit that, operating at 17,700 BTU, works to safely distribute heat throughout any indoor space at minimal cost.
 
Especially ideal for use in garages, workshops, and bedrooms, this unit is conveniently compact - just 8.25 inches deep - for ample heat wherever you need it, without the loss of space. Its sealed combustion chamber completely seals the gas flame inside the unit and away from all contact with the air in the room for added safety, operating completely electricity-free for use even during a power outage. This unit has a built in thermostat and will not work with an external thermostat.
 
This unit is a direct-vent furnace, which means that the air necessary for combustion is drawn directly into the chamber from the outside, allowing doors and windows to stay closed because no indoor air is used for combustion. The combustion products are then returned back through the vent to the outside, so that only clean, gentle, and consistent heat is delivered into the room. Direct-vent furnaces must be installed through an exterior (outside) wall, venting horizontally through the exterior wall.

For altitudes/elevations above 2,000 feet, ratings should be reduced at the rate of 4-percent for each 1,000 feet (305 m) above sea level by reducing the manifold pressure at 8% rate on the gas supply. Maximum altitude allowed for installation is 5,500 feet (1680 m).
