SP20245 – CONCENTRIC VENT KIT (3″)

A concentric vent kit runs the intake and exhaust for a condensing tankless water heater through a single wall penetration — the exhaust pipe sits inside the intake pipe. This 3″ version is for Rheem condensing tankless units and makes installation simpler by only needing one hole through the wall instead of two.

Specs: 3″ diameter, concentric (intake + exhaust), for condensing tankless water heaters

Replaces: 72951, CVENT-3, SP20245

Fits: Rheem condensing tankless water heaters requiring 3″ concentric venting.
