2.3 Locating the Furnace
(Fig S202-1, Fig S202-3B)
The location of the furnace must be as close as possible to the tile-lined brick chimney,
or factory-built solid-fuel approved chimney (ULC S629). Keep in mind also the day-to-
day operation, and place for ease of fueling and cleaning. KERR recommends
installation, if possible, in a central location in relation to the outlet registers and the use
of large warm air ducts to improve heat distribution during a power failure.
It is important to provide adequate combustion air to the furnace. It may be necessary
to add a ventilator to an exterior wall of a closed furnace room or an airtight basement.
The furnace must be installed so that the clearances as shown in Figure S202-1, or
those of local authorities are met. Also if the furnace must be installed on a combustible
floor, a non-combustible base must be built as shown in Figure S202-3B. Two layers of
hollow masonry block (4” thick) are placed at right angles to each other so that the
ventilation holes of one layer are opposite to those of the other layer. Also there must
be a minimum of one layer of fireproof board and one layer of 26 galvanized metal
beneath the masonry blocks. This base must extend beyond the furnace to a minimum
distance of 18 in (457 mm) in front and 8 in. (204 mm) on all sides.
2.4 Flue Pipe and Chimney
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,
which has a flue size equal or greater than furnace smoke pipe outlet area. 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.
