2.4.2 Flue Pipe and Chimney

The internal breech baffle should be inserted through the breech towards the front of the

furnace until it hits the internal baffle stop. The open slot running the length of the baffle

should be located on the top. This baffle is removed during the cleaning procedure. The

purpose of the baffle is to prevent short-circuiting of the flue gases out through the rear

breech. The flue gases are forced to fully heat the secondary heat exchanger, which will

maintain higher furnace efficiency.

The furnace must be located to meet a minimum venting distance needed between the

furnace and the flue. It should also be ducted so that there are a minimum number of

elbows used. The flue pipe must be installed with a gradual rise of ½” or more per foot

from the furnace to the flue.

NEVER ALLOW THE SMOKE PIPE TO RUN DOWNHILL TO THE FLUE!

The smoke pipe and chimney should be at least 7 inches in diameter. The flue pipe or

a chimney may be of different cross-sectional area than that of the appliance smoke

pipe, provided that sufficient draft is available at the appliance. Space must be provided

around the smoke pipe and the back of the furnace to allow easy access for the

purpose of cleaning. Smoke pipes must not be lighter than 24 gauge black steel. All

pipes must be securely fastened with at least 3 sheet metal screws at every joint, and

properly supported.

Always meet or exceed flue pipe clearance specifications - 18” clearance from flue pipe

to combustibles in all directions.

Connect the furnace only to an approved chimney suitable for solid fuel appliances and

capable of venting the products of combustion. The chimney must be installed with

proper clearances above roof and from adjacent structures and trees. If a masonry

chimney is used it must be in good condition and be equipped with a tile liner. Flue

thimble or flue pipe must not extend into the chimney flue, as it will reduce the draft.

Connect only to a flue or chimney capable of maintaining a negative draft of .05” wc at

all times and conditions.

WARNING: If this setting is exceeded it could cause a solid fuel fire to burn out of

control.

We recommend that the KERR SCOTSMAN Wood Furnace be connected to its own

chimney. However, two or more fuel fired appliances, other than fireplaces or

incinerators, may be connected to the same chimney.
