Kerr's Direct Wall Venting System with a completely sealed oil furnace or boiler provides an environment in which no interior air is used in the combustion process and all exhausts are vented directly to the outside through a flexible side-wall venting system. No chimney is needed. There is no impact to the sensitive balance of the home's environment from this truly sealed system.

And the Direct Vent System provides quieter operation. Unlike other side-wall venting systems, Kerr's innovative process utilizes a balanced flue - there is no fan needed to draw fresh air in or to exhaust the combustion gases. The burner always has a constant supply of combustion air and stable operating conditions. With no extra moving parts to require service and with no fan to break there is no chance for unwanted gases to enter the home.

The Direct Vent system guarantees the peace of mind of knowing the heated air inside the home is not being consumed by the furnace, 100% of the exhaust gases are withdrawn. All with quieter operation and no chimney.

Kerr's Direct Vent system is ideal for new home installation, as a retrofit in electric conversion, where a chimney is unavailable or impractical or where a better interior environment is desired.
