3" venting, stainless

The size the listing states. Diameter, material and termination all have to be on your heater maker's approved list; venting is the one part of a gas install nobody should improvise.

Will your heater accept it?

The listing names 3" venting, stainless steel and a horizontal termination.

Only venting on your heater maker's approved list is safe to use. Match the part number in the installation manual before you order.

Great for you if…

  • Your heater manual lists this exact vent system

Skip it if…

  • You'd rather wait for buyer reviews: none are captured for this listing yet
  • Your heater's manual names a different part number

What TIKSCIENCE promises

The seller states, word for word, in the TIKSCIENCE 3" Direct Vent Kit listing:

  • The ventilation pipe cover prevents rainwater from flowing into the water heater through the ventilation pipe when it rains or snows.
  • 3" Tankless water heater exhaust vent pipe kit is designed for household instant water heaters, it has a crimping end.

The seller's words, quoted as written; we haven't checked them. Your heater's manual decides whether it fits.

Our take

The verdict

The TIKSCIENCE 3" Direct Vent Kit is about 3" stainless horizontal venting, and it doesn't pretend to be more. No buyer reviews yet, so the TIKSCIENCE 3" Direct Vent Kit has to win you over on paper. Honestly, the catch: 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 Wosijm SP20285 Vent Termination Kit first.

The one thing we'd check first

Before the TIKSCIENCE 3" Direct Vent Kit ships, check your heater's vent list: it is 3" pipe, and only the vent parts your heater's manual approves are safe.

Before you buy

Your heater's vent list

This is 3" pipe. Only the vent components your heater's manual approves are safe. Same diameter is not enough.

Clearances

Distance to windows, doors and the ground is set by the manual and local code. Our installation guide covers the questions to ask.

Who installs it

Venting carries exhaust out of the house: a licensed plumber or gas fitter signs it off.
