Features of a Williams natural gas direct-vent wall furnace include a matchless pilot lighter, an automatic thermostat, a bird guard on the vent cap, a contemporary design and automatic safety and temperature controls. The furnace uses no electricity, so it continues working during power outages.
The Williams natural gas direct-vent wall furnace includes a self-generating millivolt thermostat that may be mounted to a cabinet or a wall, and the gas flame is completely concealed as an added safety measure so it has no contact with the room's air. Air needed for combustion is drawn from the outside, and combustion products are expelled out of the room. The bird guard on the outside vent prevents wild birds from nesting in the vent. The long-lived combustion chamber on the larger models have a ceramic coating, and all vent materials are included with the product for easy installation.
Each direct-vent wall furnace has a high-heat-resistant finish that is powder-coated and soft white in color to complement the home's decor. All wall furnaces are compact, space-saving models and provide an economical option for home heating. The combustion chamber has a 10-year limited warranty while all other furnace parts have a one-year limited warranty. Individuals should check local ordinances before purchasing and installing this furnace.
