CHIMNEY REQUIREMENTS

A fireclay lined masonry or Class A 103HT All-Fuel Metal

Insulated Chimney must be used in all airtight wood fur-

nace installations. The minimum recommended flue size

for the model 1602 is 6 inches, inside diameter. When mak-

ing new chimney installations, always follow the chimney

manufacturer’s instructions.

If at all possible, use the factory built, class A 103HT chim-

ney mentioned above. They are safer and perform better

than traditional masonry chimneys. If a masonry chimney

is a must, be certain it has a fire clay liner and that it is

intact, clean and recently inspected. And remember,

masonry chimneys are far more prone to the formation of

hazardous creosote.

1. The furnace should be the only heating using the

chimney flue . One furnace per flue outlet.

2. A masonry chimney should have a tile or stainless steel

liner.

3. The masonry chimney should not have any missing

mortar or loose bricks.

4. There should be no mortar or parts of the chimney

blocking the chimney flue.

5. There should be a two inch clearance between any

chimney (masonry or metal) and combustibles. (such

as the house)

6. The chimney should extend at least 2 foot above the

highest point of the house, or 2 foot above the point at

which the chimney is 10 foot from the roof.

7. The chimney should be relatively straight and vertical.
8. The portion of an all-fuel metal chimney that extends

above the roof should be well secured.

9. A masonry chimney should be built on footings and

not attached to the house.

10. A rain cap, complete with an animal or bird screen,

should be installed on top of the chimney.

CREOSOTE - FORMATION AND NEED

FOR REMOVAL

When wood is burned slowly, it produces tar and other

organic vapors, which combine with expelled moisture to

form creosote. The creosote vapors condense in the rela-

tively cool chimney flue of a slow-burning fire. As a result,

creosote residue accumulates on the flue lining. When

ignited, this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected

at least twice monthly during the heating season to deter-

mine if a creosote build-up has occurred. If creosote has

accumulated, it should be removed to reduce the risk of

a chimney fire.

SMOKE PIPE INSTALLATION

Clearances to combustible materials (i.e. paneling, ceil-

ing tile, sheet rock, plaster, draperies, casements or wood

trim, etc.) will vary with the type of flue connection used.

Be sure to maintain the specified clearances for your type

of installation.

According to NFPA standards, single wall stove pipes

can be within 9” of combustibles provided an approved

fire retardant material covered with 28 gauge sheet

metal, spaced out 1” on non-combustible spacers, is

utilized. See illustration.

When using a Class A or double wall flue pipe connection,

follow the manufacturer’s instructions.
When constructing a single wall smoke pipe, the following

guidelines must be observed.

1. The connector pipe should be 24 gauge or heavier

stainless steel or black pipe.

2. Secure all joints with three #8 screws.
3. If the connector pipe must pass through a wall, an ap-

proved insulated or ventilated thimble, at least three

times the diameter of the smoke pipe must be used.

(i.e. a 6” diameter smoke pipe needs an 18” thimble).

The connector pipe should never be used as a chimney.
