Concentric Vent Termination
Easy to install and saves. A lot of time versus putting one together yourself.

quality is terrible
the Y fitting is not at any workable angle, not a 45 or a 22.5 therefore numerous other fittings are required. Also the 90 for the top at the roof is not schedule 40 and will not fit the vent section , so here we are chasing something to fit. I would not recommend to anyone.

How long can venting pipes be
todd on Jul 24, 2016
BEST ANSWER: The longest venting pipe CPO retails is 36in. The pipe length can vary depending on where if exhaust is in the roof, or through an exterior wall
The Rheem SP20245 Concentric Vent Termination Kit shows a 90° joint; where does that belong on a roof install?

BEST ANSWER: For technical support, please contact a local installer or Rheem directly (866-720-2076)
Water heater in crawlspace mounted on foundation. Venting is on outside wall, not through roof. Venting needs to come out of heater, then a 90' right angle to go out exterior wall, then 90" right angle straight up.

Do I have to cut two holes through my exterior wall and then attach this vent on the outside?

Or is there a way to attach this vent in the crawlspace and add two 90" right angles to it.
