Chimney Connection

MASONRY CHIMNEY

Before using an existing masonry chimney, clean
the chimney and inspect the flue liner to be sure
it is safe to use. Make repairs before attaching
the furnace. The connector pipe and fittings
you will need to connect directly to a masonry
chimney are shown.
The chimney connection should be as short as
possible.
If the connector pipe must go through a combus-
tible wall before entering the masonry chimney,
consult a qualified mason or chimney dealer.
The installation must conform to local fire codes,
and N.F.P.A. 211.
DO NOT CONNECT THIS FURNACE TO
A CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.
The chimney used for a furnace must not be used
to ventilate the cellar or basement. If there is
a cleanout opening at the base of the chimney,
close it tightly.
LISTED FACTORY BUILT CHIMNEY
Carefully follow chimney manufacturer's instruc-
tions. Use only a Listed Residential Type or
Building Heating Appliance Chimney. If your
chimney starts at the ceiling (Fig. 7), you will
need enough 6" pipe to reach the ceiling.
The top of the chimney must be at least 3 feet
above the roof and be at least 2 feet higher than
any point of the roof within 10 feet (Fig. 7).
