SECTION 8: VENTING<br />
8.11 Outside Combustion Air Supply<br />
IMPORTANT: If the building has a slight negative<br />
pressure or corrosive contaminants such as<br />
halogenated hydrocarbons are present in the air, an<br />
outside combustion air supply to the heater is<br />
required. Seal all combustion air pipe joints.<br />
The air supply duct may have to be insulated to<br />
prevent condensation on the outer surface. The<br />
outside air terminal must not be more than 1' (31 cm)<br />
above the vent terminal.<br />
Use of optional outside combustion air is not<br />
recommended with unvented heaters.<br />
