P35i Fireplace Insert
D. Existing Fireplace Installation:
If using a short run of venting, whether flex or rigid,
through the damper and into the chimney flue; The
Damper must be removed or locked in the open posi-
tion and sealed with a plate constructed of steel or
other non-combustible material.
Kaowool, mineral wool or other non-combustible insu-
lation 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.
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

Standard for Lining Systems for
Existing Masonry or Factory Built
Chimneys and Vents, or CAN/ULC-
