Combustion Air Requirements
Failure to provide adequate combustion air can lead to increased
carbon monoxide production and increased emissions of combustion
gases into the building, which may cause death or serious injury.
The furnace must have a minumum supply of
60 cubic feet of air per minute. Consult a
qualified furnace installer to analyze if the air
supply is adequate. In newer air-tight homes,
the combustion air may need to be brought in
from the outside.
Venting
Failure to provide correct chimney venting can lead to increased
carbon monoxide production and increased emissions of combustion
gases into the building, which may cause death or serious injury.
Do not connect this heating appliance to a
chimney flue serving any other heating
device.
Venting may be provided using a lined masonry
chimney or a listed chimney (class ‘A’). The
chimney has two functions:
1. To exhaust smoke and flue gases that are the
result of combustion.
2. To provide “draft” to the furnace. This provides a
continous supply of fresh air into the appliance so
that proper combustion is possible.
Important Installation Points
•
The connection from the heating appliance to
the chimney must be made using 6" black
pipe.
•
Avoid using more than two elbows in
connecting the furnace to the chimney.
•
Any horizontal runs of connector pipe should
have a minimum rise of 1/4" per foot of run to
allow condensation to flow back to the
firebox.
•
A minimum distance of 18" must be
maintained between the connection pipe and
combustible wall surfaces.
•
A minimum distance of 32" must be
maintained between the connection pipe and
combustable ceiling surfaces.
Masonry Chimney
An existing lined masonry chimney must be
cleaned and inspected. All connections made to
the chimney must comply with NFPA Standard
211 and all applicable building codes. Consult a
qualified furnace installer and/or local building
inspector to make sure the chimney and
connections comply and are safe.
Listed Chimney
A listed chimney must be rated for a solid-fuel
burning appliance and must comply with NFPA
