SSI30 Wood Insert

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 ue 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 5
4. The chimney connector shall not pass through an attic,
roof space, closet, concealed space, oor, ceiling, wall
or any partition of combustible construction.
5. The minimum overall height of your chimney should be
15' (5 m) from the oor.
6. Do not use makeshift compromises during
installation.

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 signicant 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 re.
Failure to keep the chimney and connector system clean
can result in a serious chimney re.
The conditions for a chimney re 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 ue of a slow burning re. As a result
creosote residue accumulates on the ue lining. Creosote
is a ammable and, when ignited, make an extremely hot
re within the ue 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 res rather than large smoldering ones.
You can never be too safe. Contact your local re authority
for information on what to do in the event of a chimney
re, and have a clearly understood plan on how to handle
one.
Maintaining a clean chimney is important. Chimneys should
be inspected regularly for creosote buildup. A straight
chimney is easier to clean than one with 45 or 90 degree
bends. A bend requires the pipe to be removed for cleaning.
The insert bafe must be removed when cleaning the
chimney. Page 18. Chimney sweepings will build up on top
of bafe causing a blocked ue and/or a re hazard.
Most factory made “Class A” steel chimneys have a layer
of insulation around the inner ue. This insulation keeps
the smoke warm and protects the surrounding structure
from the high ue temperatures. Because the insulation is
less dense than masonry, the inner steel liner warms up
more quickly than masonry chimney; this makes the steel
chimney support a good draft more quickly than masonry
does.
Because the chimney’s function is to keep the smoke
warm, it is best to locate it inside the house. This location
uses the house as insulation for the ue and allows some
radiant heat release form the ue into the home. Since an
interior chimney doesn’t continuously lose its heat to the
outdoors, less heat from the insert is required to get it warm
and keep it warm.
The ue size for a controlled-combustion appliance should
be based on the cross-sectional volume of the insert ue
outlet. In this case, more is denitely not better. Hot gases
lose heat through expansion; if a insert with a six-inch ue
collar (28 square inch area) is vented into a 10" x 10" ue,
the gases will expand to over three times their original
volume. As gases cool with expansion, draft strength
decreases. If the oversized ue is also outside the house,
the heat it absorbs will be conducted to the outdoor air and
the ue will remain relatively cool.
