SECTION 7: AIR SUPPLY

SECTION 7: AIR SUPPLY

7.1 Separated Combustion Installation

When installed as a separated combustion heater (UHA[X]S), the air for combustion is drawn in from outside the building. It is important to ensure that there is adequate space around heater to provide air for the axial air distribution fan.

7.2 Unvented Installation

It is important to ensure that there is adequate fresh air supply at all times for both combustion and heating requirements in accordance with local and national codes.

WARNING: Combustion by-products contain a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

7.3 Building Ventilation

Where ventilation is required, air must be taken from an outside point where it is not likely to be contaminated or obstructed.

7.4 Outside Combustion Air Supply

If outside combustion air supply is required, separated combustion model (UHA[X]S) heaters must be used.

Caution: If the building has a slight negative pressure or corrosive contaminants such as halogenated hydrocarbons are present in the air, an outside combustion air supply to the heater is required. Seal all combustion air pipe joints.

The flexible air duct may have to be insulated to prevent condensation on the outer surface. The outside air terminal must not be more than 1' (31 cm) above the vent terminal.

7.4.1 Length Requirements

Follow the constraints listed on Page 16, Section 6.7.
