(Kit# 91-53500)
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
will attach to the back of the stove. When using the
outside air kit, install the Hearthstone’s Kit #91-99400
to attach the heater to the structure.
The International Residential Code (IRC) does not
allow the outside air duct to terminate higher than the
appliance. Some building officials also do not like to
see any 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.
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.
Dampers allowing 100% closure should be sourced
in air intakes which are directly connected to the
outdoors (Canada).

ONFIGURATION REQUIREMENTS
•
WARNING: DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE USED BY ANOTHER APPLIANCE
•
WARNING: THE CHIMNEY AND REQUIRED
CHIMNEY CONNECTOR MUST BE IN GOOD
CONDITION AND KEPT CLEAN.
•
Single wall connector that is 24 MSG or 25 MSG
blued steel stovepipe.
•
Double wall connector (close clearance pipe)
which is used with a listed, factory-built “Type HT"
chimney or with a masonry chimney to reduce
clearances, is available from several
manufacturers, your dealer can help you choose.
Some air insulated connector pipe models
available are Simpson Dura Vent DVL and
Metalbestos DS. Security, GSW and Ameritec
also have acceptable close clearance connector
pipe.
•
When used in a mobile home, a spark arrester is
required. (See page 29)
•
The chimney connector cannot pass through a
floor or ceiling, nor any attic or roof space, closet
or similar concealed space. Where venting
requires passage through a wall or partition of
combustible construction, the installation must
conform to NFPA Code 211 or CAN/CSA - B365.
•
It is very important to follow minimum clearances
for chimney connectors to combustibles such as
walls and ceilings when installing the stove.
Typical chimney connector clearances are
outlined below. The single wall clearances are
generic; the double wall clearances shown are for
Simpson DuraVent DVL.
•
The chimney must be a type suitable for solid fuel.
•
CHECK THE SPECIFICATIONS FROM THE
MANUFACTURER OF YOUR CONNECTOR.

The complete venting system consists of several
components: chimney connector, wall thimble, wall
pass-through, chimney, and liner. It is
absolutely
necessary
that you install all of these components
and maintain the clearances to combustibles
discussed earlier to ensure a safe stove installation.
To protect against the possibility of a house fire, you
must properly install and constantly maintain the
venting system
. Upon inspection, immediately
replace rusted, cracked, or broken components.
•
The
chimney connector
is the stovepipe from the
woodstove to the chimney. The chimney
connector stovepipe is 6" (152 mm) diameter, 24
MSG or 25 MSG blued steel connector pipe.
Do
not use aluminum or galvanized steel pipe
- they
cannot withstand the extreme temperatures of a
wood fire.
•
The
thimble
is a manufactured (or site-
constructed) device installed in combustible walls
through which the chimney connector passes to
the chimney. It keeps the walls from igniting. You
must use a wall thimble when installing a chimney
connector through a combustible wall to the
chimney.
