Vent Installation
• All vent sections and elbows utilize twist lock 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.
