that of a vacuum cleaner with a hole in the hose. In some
extreme instances, the other appliances can even impose
a negative draft and result in a dangerous draft reversal.
ChIMNEY
Refer to chimney and chimney connector manufacturer’s
instructions.
Contact your local building authority for approved methods
of installation
1. This appliance requires a masonry or pre-manufactured
chimney listed to ULCS629 (Canada) and UL 103 HT
(USA) sized correctly.
2. If a masonry chimney is used it is advisable to have your
chimney inspected for cracks and check the general
condition before you install your unit. Re-lining may
be required to reduce flue diameter to the appropriate
functional size.
3. The chimney should extend at least 3' (914 mm) above
the highest point where it passes through the roof, and
at least 2' (610 mm) higher than any portion of a building
within 10' (3 m).
Figure 2
4. The chimney connector shall not pass through an attic,
roof space, closet, concealed space, floor, ceiling, wall
or any partition of combustible construction.
5. The minimum overall height of your chimney should be
15' (5 m) from the floor.
6. Do not use makeshift compromises during
installation.

The 2'-3'-10' Chimney Rule
At the very least, inspect the chimney connector and
chimney at least once every two months during the heating
season to determine if a buildup of creosote or soot has
occurred. If a significant layer of creosote has accumulated
(1/8" (3 mm) or more], or if soot has accumulated, either
should be removed to reduce the risk of a chimney fire.
Failure to keep the chimney and connector system clean
can result in a serious chimney fire.
The conditions for a chimney fire develop as follows: 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 relatively
cool chimney flue of a slow burning fire. As a result
creosote residue accumulates on the flue lining. Creosote
is a flammable and, when ignited, make an extremely hot
fire within the flue system which can damage the chimney
and overheat adjacent combustible material.
To reduce the amount of creosote that may form, remember
to provide adequate air for combustion and to strive for
small, intense fires rather than large smoldering ones.
You can never be too safe. Contact your local fire authority
for information on what to do in the event of a chimney
fire, and have a clearly understood plan on how to handle
one.
ChIMNEY CONNECTOR guIdElINES
Chimney connector is the double-wall or single-wall pipe
that connects the stove to the chimney. The chimney is a
masonry or prefabricated structure that encloses the flue.
Chimney connectors are used only to make the connection
from the stove to the chimney.
Double-wall chimney connectors must be tested and
listed for use with solid-fuel burning appliances. Single-
wall chimney connectors should be made of 24 gauge or
heavier steel, and should be 6” (150 mm) in diameter. Do
not use galvanized connector; it cannot withstand the high
temperatures that can be reached by smoke and gases,
and may release toxic fumes under high heat.
If possible, do not pass the chimney connector through a
combustible wall or ceiling. If passage through a combus-
tible wall is unavoidable, refer to the section following on
Wall Pass-Throughs. Do not pass the chimney connector
through an attic, a closet, or any similar concealed space.
The whole connector should be exposed and accessible
for inspection and cleaning.
In horizontal runs of single-wall chimney connector without
protective shields, maintain a clearance of at least 26” (660
mm) from the ceiling. For information on reduced clear-
ances using shields on single-wall chimney connector or
using double-wall connectors, see the clearance chart on
Page 15
.
Keep the horizontal run of chimney connector as short
and direct as possible, with no more than two 90° turns.
Slope horizontal runs of connector upward 1/4” per foot
(20 mm per m) going from the stove toward the chimney.
The recommended maximum length of a horizontal run is
3’ (914 mm). The recommended total length of chimney
connector is 8’ (2.4 m).
In cathedral ceiling installations, extend the prefabricated
chimney down to within 8’ (2.4 m) of the stove.
