IMPORTANT - Make sure the chimney and fi rebox are clean and free of
soot and ashes before installation begins. Failure to do so may result in
the transfer of soot into the room by way of the room air blower.
(USA only) Venting Into an Masonry Fireplace
In the USA, as a minimum the vent connector from the insert fl ue outlet
must extend a minimum of 18” above the damper and the damper area
must be sealed to prevent dilution air from entering the chimney which
will affect proper drafting of appliance. In Canada, this appliance requires
a full reline when installing into a masonry fi replace.
This pellet insert may be installed into a masonry fi replace (built to UBC
37 or ULC S628 standards) as illustrated on this page. When installing
into a masonry chimney, in the USA it is recommended that the exhaust
vent be extended to the top of the chimney as shown on Page 18 (in
Canada, this is Required). However, in the USA, if the vent pipe does
not extend to the top of the chimney, the vent must extend a minimum
of 18” above the damper. You must seal the damper area so that the air /
exhaust in the chimney cannot communicate with the air in the fi replace
fi rebox (this is a positive fl ue connection. See the following instructions
for one method of sealing fl ue).
(USA and Canada) Direct Connection / Positive Flue Connection
See the following instructions for Approved Methods of Achieving a
Positive Flue Connection.
A qualifi ed installer should evaluate the existing fi replace to determine
the best method for achieving a positive fl ue connection between the
vent pipe or liner and the existing fi replace chimney. The most common
method for achieving a positive fl ue connection in masonry fi replaces is
to secure a seal-off plate (i.e. 22-gage sheet steel) in the fi replace throat
using masonry screws. Other acceptable methods include packing non-
combustible material (i.e. rockwool) around the vent pipe or using a fl ue
adapter. Whatever “seal off” method is used must effectively seal the area
to prevent room air passage to the chimney cavity of the fi replace.

Positive Flue Connection into
a Masonry Fireplace without a
Full Reline
The Profi le 30 INS-2 does not
require a full reline (in USA
only) when installing into a
masonry fi replace, however,
it is recommended to ensure
proper drafting of the appliance.
The vent connector from the
insert must extend a minimum
of 18” above the damper and
the damper area must be sealed
to prevent dilution air from
entering the chimney which
will affect proper drafting of
appliance
The vent pipe must extend a
minimum of 18” above the
damper. The chimney must not
be corroded or damaged in any
way for this type of installation
to be permitted.
A non-combustible seal is
required at the damper area
(to prevent dilution air from
entering the chimney). See
