faultY chiMneY and/or draft ProbleMs -
causes and cures

A  sound  chimney  system  is  imperative,  especially  when  burning
wood. Indoor chimneys, either masonry or type "HT" metal chim-
neys  are  best.  Because  warm  air  rises,  a  warm  chimney  allows
the smoke and other by-products of combustion a natural exit up
and out the chimney. Outdoor chimneys should be your last choice.
Cold air naturally falls right down the cold chimney. Until the heat
from  the  furnace  warms  the  chimney,  there  is  no  natural  draft  to
allow the smoke and by-products of combustion to rise naturally up
the chimney. Outdoor class "A" triple wall is not acceptable because
their  thermo-siphon  design  will  not  allow  the  chimney  to  heat  up,
causing heavy creosote build-up and possible chimney fires.

If you know your chimney is sound and you still have downdraft
problems such as smoke or smell in the room in which the furnace
is located, your chimney may not be operating properly. One or
more of the following suggestions may be necessary.

1. Barometric draft control- This control must be set at .03.

This is just a guide. It must be set with a draft gauge to
prove that the chimney is drawing .03.

2. Combustion air -You must have outdoor combustion air

introduced into the room where the furnace resides in the
manner described on page 17. This method supplies air
for combustion as well as replacing air that is drawn out
by the chimney. Leaky doors and windows will not provide
acceptable results.

3. Cold outdoor chimney -Sometimes in the spring or fall, or

if you live in a mild climate, your heat demands are small
and your chimney just does not heat up enough to induce
a natural exit up draft, you may want to consider a power
vent to force a draft up the chimney. A Model D-3 or AD-1
power venter is available from Tjurnland Manufacturing
Co. in White Bear Lake, Minnesota or Model D1-2 is avail-
able from Field Controls Co., Kinston, North Carolina.

4. Chimney not tall enough -Your chimney must terminate

at least 2 feet above the peak of the roof. Adding more
chimney height sometimes cures the problem. (See Fig.
12, page 14)

5. Home located on side of hill- When the wind blows over a

hill toward your home, the wind will fall. This could cause
a downdraft into your chimney. Some common solutions
to correct downdrafts are to add a chimney cap with a
weather vane, add height to the chimney or add a power
venter.

6. Tall trees near your home -If you have trees that are near

and higher than your home, a downdraft can occur when
the wind blows. Correct the same way as if you live on the
side of a hill or in a valley.

7. Chimney too large -Your chimney should not be more

than 8 inches in diameter or the equivalent. If too large,
the  sides  of  the  chimney  may  not  heat  up  to  create  a
natural  draft.  When  this  happens,  the  smoke  and  gases
cool. They become heavy and other gases from the fire
try to penetrate this heavy column of cool air. This results
in  back  puffing,  poor  combustion  or  burning  and  may
cause odors in your home. The solution is to improve your
chimney or line it with 8-inch type 304 stainless steel flue
liner.  If  your  large  chimney  is  outside  masonry,  insulate
between the masonry and 8-inch flue pipe.
