Chimney & venting
Types Of Chimneys
The chimney is one of the most important, yet most neglected and misunderstood portions of any solid fuel burning stove installation. Do not connect this stove to a chimney flue serving another heating de- vice.
THE STOVE MUST BE CONNECTED TO ITS OWN
UNDER NO CIRCUMSTANCES SHOULD A MANUAL FLUE DAMPER BE INSTALLED IN THE SMOKE PIPE BETWEEN THE STOVE AND THE CHIMNEY.
NO DAMPER, HEAT SAVER OR AUTOMATIC VENT DAMPER DEVICE SHOULD BE INSTALLED IN OR ON THE SMOKE PIPE.
CAUTION: THE CHIMNEY MUST BE A CLASS “A” CHIMNEY, IN GOOD OPERATING AND CLEAN CONDITION.
NOTE: THE USE OF ALUMINUM TYPE “B” GAS VENT FOR SOLID FUELS IS UNSAFE AND PRO- HIBITED BY THE NATIONAL FIRE PROTECTION AGENCY CODE.
There are three types of class “A” chimneys:
1.Masonry with tile liner, to include brick or stone. It must be supported on grade level foundation.
2.Insulated, manufactured chimney, listed or certified by a national test agency.
3.
If your masonry chimney has not been used for some time, have it inspected by a qualified person. If a listed or certified manufactured chimney is to be used, make certain it is installed in accordance with the manufac- turer’s instructions and all local and state codes.
The minimum recommended height for solid fuel chimneys is 16 feet from the stove collar. The chimney must be two feet higher than anything within ten feet. It also must extend three feet above the point where it intersects or exits the roof line.
The three foot, two foot, ten foot rule
In order to have a properly operating solid fuel heat- ing system, the chimney must be capable of provid- ing the necessary draft. The minimum required draft is .06 inches of water column (W.C.). This must be measured using a draft gauge. If the chimney cannot supply this constant draft, the stove will not operate properly. A barometric damper may be used and prop- erly adjusted to compensate for excessive draft only.
IMPORTANT: When you measure the the draft, the stove must be operating with sufficient time given for the stove and chimney to warm. Burn for at least thirty minutes. The draft reading is best taken 18” up from the center of the flue outlet, in the connector pipe. Drill a hole in the pipe for the meter tube, and fill it with a screw or silicone when done with the test.
IMPORTANT: The connector pipe must be 24 gauge or thicker.
When connecting the flue pipe to the stove, the first section should be installed inside the stove collar. It should be secured to the collar with, at least, three screws or rivets.
Do not pass the connector pipe through a wall or ceiling without first checking with your local codes. If allowed, use only approved
NOTE: All horizontal runs of venting should have a 1/4 inch of rise per foot of length.
Use no more than two 90° elbows in the connector. If a barometric damper is needed, to compensate for excessive draft, install it only in a vertical section of vent pipe.
