Non-Catalytic Convection Heater

Fireplace Installations -
Through the Fireplace
The Convection heater may be installed either without
legs* as a ireplace insert, or with standard legs at-
tached - depending on the safety regulations that apply
to your situation, the height of the ireplace opening and
your own preference. For either situation, the chimney
connector/positive connection kit extends back from the
stove, enters the ireplace cavity, and turns upward. It
then passes through the ireplace damper opening and
smoke chamber and connects to the chimney lue.
In such installations, a “positive connection” must be
made to the chimney lue with a special kit available
from your local dealer. Also, special clearance and loor
protection provisions must be observed. These provi-
sions are discussed in the Clearance and Floor Protec-
tion sections respectively.
Wall Pass-Throughs
Whenever possible, design your installation so the con-
nector does not pass through a combustible wall. If you
must use a wall pass-through in your installation, check
with your building inspector before you begin and con-
struct it in accordance with local building codes. Also
check with the chimney connector manufacturer for any
speciic requirements.
Accessories are available for use as wall pass-
throughs. If using one of these, make sure it has been
tested and listed for use as a wall pass-through.
All combustible material in the wall is cut away a sufi-
cient distance from the single-wall connector to provide
the required 12” (305 mm) clearance for the connector.
Any material used to close up the opening must be non-
combustible.
The following wall pass-through methods may be ap-
proved in your area:
• Use a section of listed factory-built chimney with a
nine-inch clearance to combustibles.
• Place a chimney connector pipe inside a ventilated
thimble, which is then separated from combustibles
by 6” (152 mm) of iberglass insulating material.
•
If the stove is installed without legs, we recommend
the use of noncombustible tiles or pavers as shims to
allow air low into the convection air inlets under the
stove. Make sure not to block air slots instove bottom
with shims or remove fan cover.
• Place a chimney connector pipe inside a section of
listed solid-insulated, factory-built chimney, with an
inside diameter 2” (51 mm) larger than the chimney
connector and having 1” (25 mm) or more of insula-
tion and maintaining a minimum 2 inch air space
between the outer wall of the chimney and combus-
tibles.
In Canada:
The Canadian Standards Association has
established different guidelines. Figure 11 shows one
method, in which all combustible material in the wall is
cut away to provide the required 18” (450 mm) clear-
ance for the connector. The resulting space must
remain empty.
