4.1Types of Chimneys

The chimney is one of the most important, yet most neglected and misunderstood portion of any solid fuel burning installation. We do not recommend that the stove be con- nected to a chimney with other heating devices.

THE STOVE MUST BE CON- NECTED TO ITS OWN TILE- LINED FLUE. A MINIMUM FLUE SIZE OF 8" X 8" IS NECESSARY FOR PROPER OPERATION AND APPROVED FOR ALL FUELS.

UNDER NO CIRCUMSTANCES SHOULD A MANUAL FLUE DAMPER BE INSTALLED IN THE SMOKE PIPE BETWEEN STOVE AND CHIMNEY!

No damper, heat saver, or automat- ic vent damper device should be installed in or on the smoke pipe.

N O O T H E R A P P L I A N C E S SHOULD BE VENTED TO THIS FLUE!

CAUTION: THE CHIMNEY MUST BE A CLASS “A” CHIMNEY IN GOOD OPERATION CONDITION.

NOTE: THE USE OF ALUMINUM TYPE “B” GAS VENT FOR SOLID FUELS IS UNSAFE AND PROHIB- ITED BY THE NATIONAL FIRE PROTECTION ASSOCIATION CODE.

There are three types of class “A” chimneys:

A. Masonry with tile liner to include brick or stone. It must be supported on grade level founda- tion.

B.Insulated Class “A” manufac- tured chimney, listed or certified by a national test agency.

C.Triple Wall Metal Class “A” chimney, listed or certified by a national test agency.

If your masonry chimney has not been used for some time, have it inspected by a qualified person (building inspector, fire department personnel, etc.). If a listed or certi- fied manufactured chimney is to be used, make certain it is installed in accordance with the manufacturer’s instructions and all local and state codes. See Figure No. 1 of Manufactured Chimney Installations and Figure No. 2 of masonry Chimney (note roof clearance) in accordance with NFPA 211.

In order to have a proper operating solid fuel heating system, the chim- ney must be capable of providing the draft required.

The minimum required draft is .06 inches W.C. (water column). This must be measured using a draft gauge.

If the chimney cannot supply this constant draft, the unit will not operate properly.

In some installations, a barometric draft regulator may be used and properly adjusted to compensate for excessive draft.

IMPORTANT!

Whenever you measure the draft, the stove must be operating and suf- ficient time given for the chimney and stove to warm up. This should take a minimum of thirty minutes.

The draft reading is taken 18" up from the center of the stove flue outlet in the smoke pipe.

REASONS for insufficient draft readings:

A.Leaky Chimney - Air leaking in around a loose fitting clean-out door, flue pipes not tight at the joints, improper plug openings or defective masonry.

B.Chimney Improper Height - Chimney does not extend through the roof to a sufficient height to pro- mote sufficient draft or causes a down drafting condition to take place. (See Figure No. 3)

C.Obstructions in the chimney. Check prior to using by holding a mirror in chimney clean-out door. This will give a view of the chimney.

D.Trees or Other Topographical Barriers - Impeding the chimneys operation or causing a down draft condition to exist. This can also be caused by adjacent buildings or the roof of the same structure where the chimney is not high enough. (See Figure No. 3)
