CORRECTION
Extend chimney 24 inches above roof
and surrounding objects within 30 feet.
Remove.

Replace loose bricks and mortar.
If all other causes have been
eliminated a new chimney may have
to be built.
Replace loose bricks or mortar.
Remove.
Have chimney cleaned.
Clean out.
Straighten or lengthen offset.
Furnace ideally should have its own
flue. If this is not possible, smoke pipe
should be connected as shown in
Figure 23.
Make flush with inside of chimney.
Cement joints, shorten and eliminate
elbows.
Seal openings permanently.
Seal openings, close door tightly.
Allow 2 to 4 weeks to dry.
Open barometric damper.
CORRECTION OF POOR CHIMNEY DRAFT CONDITIONS
FIGURE 24. CHIMNEY PROBLEMS
FIGURE 25.
Pipe pushed too far
inside elbow, as shown, interferes
with draft.
FIGURE 26.
If chimney ends only a
short distance below point where
flue enters, make a “toothpick joint”
as shown. Remove soot from below
regularly.
FIGURE 27.
If it is necessary to
connect more than one heating
appliance to the same chimney,
connect furnace flue pipe as “B.”
Connect lower BTU appliance pipe
as “A.”
