Please note: All HVAC equipment must be installed by a licensed or otherwise qualified HVAC dealer or contractor; and also must be installed in accordance with the manufacturer's installation instructions and in compliance with applicable codes.

External flue extensions can be used to provide additional clearance between the flue and your roof. This can be helpful in areas with heavy snowfall, as accumulated snow can have adverse effects on the flue.

Key Features:

• Bottom Flue Connections: 5-3/8" (Inner) and 8-3/8" (Outer)
• Top Flue Connections: 5-1/2" (Inner) and 8-1/2" (Outer)
