PROBABLE CAUSE
located.
• Defective main bearings
• There is an oily film that
remained on the steel after
the manufacturing process.
Firing the furnace has raised
the temperature of the fire-
box to a level that is suffi-
cient to vaporize the resi-
due.
• Furnace is not connected
to return air and is drawing
smoke fumes from the flue.
• Excessively long run of
stove pipe from furnace to
flue.
• Too many elbows.
• Insufficient flue size.
• Cast iron damper in
"CLOSED" position.
• Flue has a cold spot which
inhibits exhaust discharge
from rising properly. This
SUGGESTED REMEDY
an acceptable balance. If you
are unsuccessful, contact
your supplier.
Return the blower to your
supplier for replacement.
This odor should disappear
after a few hours of usage.
Connect to return air duct
system.
Relocate the furnace so that
the horizontal run does not
exceed five feet (5’) and
has a two inch (2")
rise per foot.
The run should not contain
more than two (2) elbows.
Replace with a larger flue pro-
viding a minimum of 50 (fifty)
square inches of draft area
but not more than 100
square inches of draft area.
If flue is within these specifi-
cations, check the draft with
a gauge. Your flue should
provide a minimum of .08
water column inches.
Open damper.
Check entire flue for struc-
tural integrity and leakage.
Correct or repair as needed.
