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.

Figure 3

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.

4.3What 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.

4.4Chimney 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.
