Modine 6" Vertical Concentric Vent Kit for PTX/BTX 250-400

The 77793 Modine vent kit is a 6-inch vertical concentric kit, a specialized venting solution for Modine gas-fired unit heaters.

This kit streamlines the venting process by allowing a single wall penetration for exhaust and intake, making installation more efficient and aesthetically pleasing.

It’s engineered to accommodate 6″ vent piping for both intake and exhaust, with the exhaust pipe passing through the larger 8" fresh air intake pipe. This concentric design maximizes efficiency while minimizing external penetrations.

Includes:

• Concentric Vent Adapter Box
• Combustion Air Inlet Terminal
• Outlet Vent Termination Cap

Compatibility: This kit is specifically designed for vertical installations and is compatible with a wide range of Modine unit heaters, including:

• PTX series (250, 300, 350, 400)
• BTX series (250, 300, 350, 400)
