Our take
The best thing about the GASLAND 3" Stainless Vent Pipe Kit is 3" stainless horizontal venting. No buyer reviews yet, so this GASLAND vent kit has to win you over on paper. The catch with the GASLAND: no word on the exact models it fits. We'd pick it if your heater manual lists this exact vent system; otherwise, put it next to the Rheem RTG20280-1 Vent Termination Kit first.
Before you order the GASLAND 3" Stainless Vent Pipe Kit, check your heater's vent list: it is 3" pipe, and only the vent parts your heater's manual approves are safe.
This is 3" pipe. Only the vent components your heater's manual approves are safe. Same diameter is not enough.
Distance to windows, doors and the ground is set by the manual and local code. Our installation guide covers the questions to ask.
Venting carries exhaust out of the house: a licensed plumber or gas fitter signs it off.
