Penetrations from sheet metal screws used to

fasten the ductwork to the cabinet of the unit

should only be placed into the duct flange provided.

This is to avoid contact and damage of the

heating/air conditioning coils and internal wiring.

Ducting

The duct sizing for the furnace section can be

determined using HRAI Residential Air System

Design Manual, SMACNA, or any other industry-

recognized manuals.

Note: "Combo units" normally deliver air at approx.

110°F (43°C), and therefore may require larger than

normal ductwork. When installing the Clean Air

Furnace as a replacement unit on a retrofit application,

always calculate the size of duct that is there.

Any ductwork running through unconditioned

space must be sealed properly and insulated to

prevent heat loss. All local codes must be

followed in determining the amount of insulation

needed.

The ventilation section consists of two 6" (15.2cm)

round ports located on the side of the cabinet,

which vent to the outside. Insulated

ducting with a vapour barrier such as flex-ducting,

ridged pipe wrapped in pipe sleeve, is required to

prevent condensation from occurring on the pipe.

Also the airflow in these lines is designed to be

balanced. (See "Balancing Airflows" in this manu-

al, for damper location and procedure).

Warning: A backdraft damper is required in the

exhaust air duct to prevent cold air from entering the

unit when the Clean Air Furnace is not running.
