Canadian Fire Hearth Rigid Vent System
Vent Installation
• All Rigid vent sections and elbows utilize slip type joints.
• Each joint should be secured by three screws.
• High temperature sealant is recommended at the connection start of the
venting on the appliance end. Use high-temperature silicone or Mill-
Pac©.
• If for any reason the venting must be disassembled upon re-assembly
all vent joints must create a tight fit. If in doubt apply high-temperature
sealant to ill fitting sections.
• Horizontal venting runs will require non-combustible supports such as
metal strapping. Generally every six feet is preferable.
• Co-Axial 2 ply flexible chimney liner must be secured to appliance
with a minimum of three screws for both 5” exhaust and 8” air intake
sections
.• High temperature sealant is recommended at the connection start at
the appliance. Use high temperature silicone or Mill-Pac©.
• It is important to support lengths of flexible chimney liner with non
combustible strapping at three foot intervals to prevent the venting
system from dropping or sagging
. Failure to maintain a level or
horizontal rise will lead to improper combustion and can be a
safety hazard.
