11
than 8 inches of brickwork or equiv-
alent fireproofing material.
C. Where all combustible material
is cut out of the partition wall for a
sufficient distance to provide not
less than 18 inches clearance on all
sides of the connector. Any material
used to close this opening must be
non-combustible insulating material.
D. Where the section of connector
pipe passing through the wall is
replaced by a properly installed sec-
tion of factory-built chimney, the
chimney section must be listed for
solid fuel use and be insulated.
Where an existing chimney is used,
it must be large enough to provide a
draft adequate for exhausting the
gaseous products of combustion.
The cross-sectional area of the
chimney flue should be at least 25
percent greater than that of the
chimney connector (stovepipe). For
example, the common 8 inch by 8
inch chimney flue liner has an actu-
al interior cross-sectional area of
only 49 square inches (7" x 7") and,
thus, can only accommodate a 7"
stove connector.

Blower Motor - Oil twice yearly.
Grates - Keep ash drawer emptied.
Failure to do this may cause grates
to warp.
C A U T I O N ! BEFORE CLEANING
CHIMNEY AND SMOKE PIPE BE
SURE FIRE IS OUT AND INSIDE
OF STOVE IS COOL.
Cleaning The chimney, Smoke Pipe
and Spiral Chamber.
Avoid chimney fires. On a regular
schedule, check for creosote and
soot buildup in the chimney, smoke
pipe and spiral chamber. They must
be kept clean. Keep a professional
chimney sweep in mind if you have
access to one.
Steel brushes are the safest for
cleaning metal surfaces. Salt solu-
tions and some chemicals may dam-
age metal surfaces. Do not overfire
your stove. Do not burn anything
that combusts in seconds. Excessive
flue temperatures may result there-
by igniting creosote.
To clean the chimney, obtain a stiff
brush with an extendible handle and
insert the brush into the chimney
from the top. Continue the brushing
and sweeping downward until the
e n t i re length of the chimney is
cleaned.
After cleaning the chimney, the
debris will be at the bottom of the
chimney at the clean-out opening.
Open the clean-out door and sweep
the debris out into a metal contain-
er.
The smoke pipe from the stove to
the chimney can be cleaned with a
steel brush.
Cleaning of Spiral Chamber - To
clean spiral chamber re m o v e
cleanout plate in front of chamber
by using a 3/4" wrench to turn the
bolt counter-clockwise two turn s
and slide plate sideways about 1"
and remove. Take putty knife or
similar tool and scrape accumulated
residue from the spiral chamber.
The residue will fall down to the bot-
tom of the chamber and can be
removed from the flue opening in
back of the stove by means of a vac-
uum cleaner or a small scoop.
Figure 5: Connecting
Smokepipe (connector) to
Chimney Through Wall.
Two methods of connect-
ing a chimney connector
to a chimney flue where
the connector must pass
through a combustible par-
tition wall. Instead of the
asbestos board shown,
sheet metal may be used,
or a metal lath and plaster
finish may be applied at
that area. Use 24 gauge or
heavier metal. Clearance
needed is three times the
diameter of stovepie.
