Efficiency
|
With a direct-vent system, there is a positive difference in fuel economy
because outside air is used to support combustion. The air on the inside is warmed
as it recirculates around a sealed chamber. This warm air comfortably heats the
room cleanly and efficiently. |
|
Easy of Installation
|
Williams direct vent wall heaters are ideal where existing flues or chimneys
cannot be used. Just one hole through an outside wall is all you need. If you
must vent, you will receive maximum fuel economy from direct-vent heaters. |
Ignition
|
A push of the button ignites the pilot with a "matchless" piezo system. Add
an optional internal blower for even greater circulation. |
Safety
|
Safety is engineered into every Williams gas heater. Each unit contains an
automatic shut-off valve should the pilot light become extinguished, and Williams'
quality control procedures ensure that every heater is a top performer before
it goes into your home. |
Durability
|
Williams leads the field in style and durability. We use a state-of-the-art
powder coating that produces a strong finish that resists scratching and chipping.
|
Quiet
|
Williams' secret to quieter operation is our uniquely designed
burner. As gas enters the burner port, it is ignited immediately, which eliminates
delayed ignition noise and gives you quieter operation. |
Appearance
|
Williams is the only heater of its kind that features an attactive
two-tone finish that blends in with most any environment. The simple direct vent
cap on the exterior of your home projects only 6 inches. And, with the optional
thin-wall collar kit, installation on virtually
any type of structure is possible. |
