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.

10. Preventive 
Maintenance 
Instructions

10.1 Periodic and Normal 

Everyday Maintenance

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.
