Lifebreath CLEAN AIR FURNACE 60ELE - Manual (Page 6)

6
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.
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, or 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 bal-
anced. (See "Balancing Airflows" in this manual, 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. Fig. D Page 9.
Locating Intake Weatherhood
The intake weatherhood should be located as follows:
* 4-6' from ventilation exhaust hood, and upstream of
prevailing winds, if possible.
* At least 6' from a dryer vent, oil fill pipes, combustion
outlets, gas meters, garbage containers or anything
else, which may contaminate the air.
* Do not locate fresh air intake in garages, crawl
spaces or attics.
* Install 18" above grade, or above expected snow
accumulation.
