NOTE: The Chimney on the house
illustrated  is  too  low.  It  should  be
raised to compensate for drafts.

E. Chimney Size - Chimney is not
properly  sized  to  adequately  vent
the appliance. It is either too small
or too large.

F. Chimney  Offsets -  Chimneys
with  offsets  should  not  be  used.
They  cause  an  obstruction  to  draft
as well as a place for debris to col-
lect.

G. Elbow  Restrictions -  The  flue
pipe  is  connected  to  the  chimney
with too many elbows, reducing the
draft the chimney can provide.

H. Multiple Venting - No more than
one device shall vent into the same
chimney flue.

THE  MOST  IMPORTANT  THING
TO  REMEMBER  ABOUT  CHIM-
NEYS IS THEIR NEED FOR MAIN-
TENANCE  AND  CLEANING.  IF
CHIMNEYS ARE NOT CLEANED
ON A FREQUENT BASIS, IT WILL
AFFECT  THE  DRAFT,  AS  WELL
AS  BEING  A  CONTRIBUTING
CAUSE TO A CHIMNEY FIRE.

CAUTION

ANYTIME  YOU  HAVE  A  CHIM-
NEY  FIRE  THE  FOLLOWING
POINTS 

SHOULD 

BE

OBSERVED:

1. BE SURE EVERYONE IS OUT
OF THE HOUSE.

2. CALL  THE  FIRE  DEPA RT-
MENT.

3. CLOSE 

DOWN 

DRAFT

DAMPER ON STOVE.

AFTER  THE  FIRE  IS  EXTIN-
GUISHED,  DO  NOT  USE  THE
CHIMNEY  UNTIL  A  QUALIFIED
PERSON HAS INSPECTED YOUR
CHIMNEY.

4.3 What To Do When You 

Have A Problem

A. Smoke Puffs From Your 

Stove:

1. Check the chimney draft. With a
good  fire  burning,  the  chimney
should supply .06" updraft.

2. Check draft controls for proper
operation.

3. Check  the  smoke  pipe  and  be
sure it is clean.

4. Chimney  may  be  too  low.
Increase the height. Make sure the
chimney is structurally sound.

5. Add more air to the room. Your
home  may  be  so  airtight  that  not
enough oxygen is reaching the fire.

6. REMEMBER,  open  the  draft
controls  and  crack  the  fire  door
slightly  before  recharging  the  fire

chamber or checking the fire.

SPECIAL  WARNING:  NEVER
OPERATE  YOUR  STOVE  WITH
THE FIRE OR ASH DOOR OPEN!

7. Check  the  smoke  pipe  and
make certain each joint is tight and
the  connections  to  the  stove  and
chimney are airtight.

8. Check  the  ashes.  Ashpan  and
f i re  compartment  may  be  over-
loaded with ashes.

9. Check  type  of  wood  being
burned. If too green or wet wood is
being used, it may cause excessive
smoking and creosote.

10. Check  your  chimney  for  down
drafts. This is caused by air currents
being  deflected  down  the  chimney
from  higher  objects,  such  as  trees,
building and hills. This problem can
usually be corrected with an open-
vented chimney cap.

11. Make  sure  the  chimney  clean-
out door is tightly closed and sealed.

12. If other fuel-burning devices are
connected to the chimney they may
be  causing  draft  problems.  This
must  be  corrected  by  your  heating
contractor.

4.4 Chimney Details

Chimney Liners -  Most  of  the  cus-
tomer  inquiries  received  are  prob-
lems  caused  by  poor,  or  in  some
cases,  excessive  draft.  A  result  of
poor draft could be creosote, back-
puffing,  and  smoky  firebox  when
loading.  Indications  of  excessive
draft are burning too much fuel and
high stack temperatures.
