Always install furnace to operate within the furnace’s intended temperature-rise
range with a duct system that has an external static pressure within the allowable
range, as specified in Section 5 of these instructions. See furnace rating plate.
•
When a furnace is installed so that supply ducts carry air circulated by the
furnace to areas outside the space containing the furnace, the return air shall also

Sample List of Contaminants to be Avoided
The recommended source of combustion air is to use the outdoor air
supply. However, the use of indoor air in most applications is
acceptable except as follows:
•
1. If the furnace is installed in a confined space it is
recommended that the necessary combustion air come from
the outdoors by way of attic, crawl space, air duct, or direct
opening.
•
2. If outdoor combustion air is used, there must be no
exposure to the installations or substances listed in “3” below.
•
3. The following types of installation may require OUTDOOR
AIR for combustion, due to chemical exposures:
o
- Commercial buildings
o
- Buildings with indoor pools
o
- Furnaces installed in laundry rooms
