ChImNEY & vENTINg

Possible causes of insufficient draft;

A.  Chimney  Leaks  - Air  leaking  in  around  a  loose  fitting 

cleanout door, flue pipe joints and/or seams not secured, 

improper plug openings or defective masonry.
B. Chimney Too Short - The general rule for chimneys; 16 

feet tall, three feet above the roof exit, and two feet taller 

than anything within ten feet.
C.  Blocked  Chimney  -  Have  the  chimney  cleaned  and 

inspected  prior  to  installation  and  before  each  heating 

season. 
D. Trees Or Other Topographical Barriers - Impeding on the 

chimney’s operation or causing a down draft situation. This 

can also be caused by adjacent buildings or another roof 

of the same structure giving air currents a downward swirl.
NOTE: The chimney on the illustrated house is too low, it 

should be raised to compensate for down draft potential.

 

Wind direction

The most common cause of poor draft is an improperly sized 

flue liner. It is recommended that the inside dimensions of 

the  liner  be  at  least  as  large  as  the  appliance  flue  outlet 

and no larger than 125% of the collar for a round flue. An 

example,  a  8”  flue  collar  is  50  square  inches.  Increased 

by 25% would be 63 square inches, or approximately a 9” 

round flue. In general for round liners, it is recommended 

that they not be increased by more than one inch from that 

of the stove collar. This will help ensure proper draft with the 

lower flue temperatures. 

REMEMBER; 

A solid fuel burning stove can only perform 

as well as its venting system will allow it to.
THE MOST IMPORTANT THING TO REMEMBER ABOUT 

CHIMNEYS  IS  THEIR  NEED  FOR  MAINTENANCE 

AND  CLEANING.  IF A  CHIMNEY  IS  NOT  CLEANED  ON 

A  FREQUENT  BASIS,  IT  WILL  AFFECT  THE  DRAFT 

AS  WELL  AS  BEING  A  CONTRIBUTING  CAUSE  TO  A 

POSSIBLE CHIMNEY FIRE.

IF YOu hAvE A ChImNEY FIrE:

1.  GET EVERYONE OUT OF THE HOUSE.
2.  CALL THE FIRE DEPARTMENT.
3.  CLOSE  THE  DRAFT  CONTROL  KNOBS  ON  THE 

STOVE.

DO  NOT  USE  THE  CHIMNEY  UNTIL  IT  HAS  BEEN 

THOROUGHLY  CLEANED  AND  INSPECTED  BY  A 

QUALIFIED PERSON.

E. Chimney Size - The chimney can not be smaller than the 

flue exit from the appliance. Too large of a chimney could 

stay too cool to promote adequate draft.
F. Chimney Offsets - Offset chimneys should be avoided. 

The offset area can collect debris and cause a blockage.
G. Elbow restrictions - There should be no more than two 

90° elbows or the equivalent used in connecting the stove 

to the chimney flue.
H. Shared Flue - No more than one appliance shall vent into 

a single flue.
