Venting a gas heater through wall.

Direct vent water heaters with a direct vent system air for combustion is drawn from a vent pipe that runs through an exterior wall or the roof. Direct venting or side wall vent chimney and flue systems are a method of venting the exhaust gases from a heating appliance directly out through the side wall of a building while eliminating the need for a vertical chimney of any sort. Illustrations of proper gas fired water heater venting using type b double wall vent pipe through a roof above or through a chimney below include details for the flue vent connector such as the requirement of a minimum vent connector upwards slope of 1 4 per foot of horizontal run. Gas or oil fired side wall power vents are provided by several manufacturers listed at the end of this article.

Some people prefer this method since this option allows you to maintain the integrity of your roof. Direct venting and power venting systems offer greater flexibility because neither requires a direct line to the roof. Typical vents are usually galvanized sheet metal ducts vented through the wall or vented through the roof with a flue. You ll need to same tools as the ones required for a roof vent.

The size of the duct you ll use depends on the size of the vent flange on the heater.
