SECTION 8: AIR SUPPLY

WARNING

Explosion Hazard

Equipment must have access to uncontaminated air at all times.

Failure to follow these instructions can result in death, injury or property damage.

8.1 Separated Combustion Installation

When installed as a separated combustion heater (UHD[X]S), the air for combustion is drawn in from outside the building.

8.2 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.

8.3 Building Ventilation

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

8.4 Outside Combustion Air Supply

If outside combustion air supply is required, separated combustion model (UHD[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.

8.4.1 Length Requirements

Follow the constraints listed on Page 13, Section 7.7.
