What it delivers
The Rheem SP20897 Concentric Vent Kit is a concentric vent kit.
Vent parts must be the ones the heater's installation manual lists for that model, in the lengths and fittings it allows.
Order vent parts by the heater's model: the manual names the vent material and brand, the maximum length and number of elbows, and the clearances from windows and doors.
Also on the listing: features: Durable Stainless Steel Construction, Concentric Venting; material: Plastic; model: SP20897.
The listing gives dimensions of 8.25 in (W) x 42 in (H) and hardware and instructions when applicable in the box.
