(Optional Kit #96-53400)
You can connect an outside air source directly to this
stove using an optional outside air kit. The advantage
of providing outside air directly to the stove is that the
air used by the stove for combustion is taken from
outside the residence rather than from within the
room where the stove is located.
The outside air kit for this stove allows for the direct
connection of the stove's air intake to a minimum 3"
(76 mm) diameter duct (supplied by others)* which
leads to the outside of the house. When considering
placement of the duct from the outside of the house
to the hearth, keep in mind the need to avoid
structural members of the house. The outside air kit
attaches to the underside of the stove. Refer to the
instructions provided with the kit for installation.
*
An adaptor for 4” duct is available if needed. KIT #90-
53308
When using an outside air kit in Canada, the stove
must be attached to your hom
e’s floor. Use the
shipping clips that came with the stove and fasteners
long enough to attach securely to the subfloor. (The
clips and fastener heads may be painted to minimize
visibility).
Figure 7
– Outside Air Kit Detail
The International Residential Code (IRC) does not
allow the outside air duct to terminate higher than the
appliance. Some building officials restrict vertical rise
in the duct’s termination. Hearthstone recommends
the termination be at the same level, or lower than the
air intake on the stove. When using an outside air kit
in Canada, a damper allowing 100% closure shall be
installed.
Locate the termination of the duct on the outside wall
of the home in such a manner to avoid the possibility
of obstruction by snow, leaves or other material.
Screen the termination using ¼” x ¼” mesh rodent
screen and cover it with a rain/wind proof hood (flex
pipe, outside termination, mesh, and hood supplied
by others) Contact your dealer for availability.
