D. Existing Fireplace Installation:
When using a short run of venting (flex or rigid) the damper
must be removed or locked in the open position and sealed
with a plate constructed of steel or other non-combustible
material.
Kaowool, mineral wool or other non-combustible insulation
is recommended above the plate to reduce the possibility
of condensation. You will also need to wrap the venting
section between the insert frame and the damper sealing
plate. This is to prevent overheating of the fireplace cavity,
which may cause damage to the insert's motors and other
electrical components.
The connector pipe should extend through the sealing plate
and smoke chamber and into, or beyond the first flue tile.
Be sure to design the venting so that it can be easily cleaned.
Check with your local authority having jurisdiction to
determine if this venting method is acceptable. Some
Provincial, State, or Local codes may require a full liner run
to the top of the chimney. Be sure and check your local
regulations before planning the installation. In this method,
the proper flashing and rain cap are also required.

When using single wall flex, this
section of venting must be
wrapped with non-combustible
insulation to prevent excessive
heat build-up in the cavity.
When venting in this configuration, a rain cap and proper
flashing must be installed on the top of the chimney to
prevent flooding and damage.
IN CANADA: This fireplace insert must be
installed with a continuous chimney liner
of a minimum 3" diameter extending from
the insert to the top of the chimney. The
chimney liner must conform to the Class 3
requirements of CAN/ULC-S635, Standard
for Lining Systems for Existing Masonry or
Factory Built Chimneys and Vents, or CAN/
ULC-S640, Standard for Lining Systems for
New Masonry Chimneys.
