Horizontal Vent Termination Kit

This horizontal vent termination kit is designed for Rheem tankless water heaters and provides a complete termination point for exhaust gases. It is intended for installers and homeowners who need a code-compliant horizontal vent exit.

Vent Connection Size 2 Inches

The single specification that determines compatibility is the 2-inch vent connection size, which must match the heater’s exhaust outlet exactly. A mismatch would prevent a proper seal and could allow combustion products to enter the living space.

Plastic Construction Under Heat

The kit is made from plastic rated for the exhaust temperatures produced by Rheem tankless heaters during continuous operation. It resists deformation and maintains its seal over long heating cycles without softening or cracking.
