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.
D. Ex isting F ireplace Installation:
If using a short run of venting, whether flex or rigid,
through the damper and into the chimney flue The
amper must be removed or locked in the open
position and sealed with a plate constructed of steel or
other non-combustible material.
aowool, 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 urisdiction 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.
