MightyVent 5″ UL Insulated Tee with Clean-Out Cap

$195.00

The MightyVent AF 5″ insulated tee with clean-out cap makes the 90° turn from the pipe coming through your wall to the vertical chimney outside. It gives your MightyVent 5″ chimney system an easy clean-out at the bottom.

  • Wall exit made simple. Connects the horizontal through-wall pipe to the vertical section of chimney.
  • Easy clean-out. The bottom of the tee is closed with an insulated cap that comes off, so you can sweep the chimney from below without taking the stack apart.
  • Built-in drain. The cap has a 3/4″ threaded drain fitting with a 304 stainless plug.
  • Same build as the pipe. 304 stainless steel inner and outer walls with 1.18″ of ceramic fiber insulation.
  • Easy installation. 6-tooth twist-lock connections with included clamps for the tee and the cap.

The MightyVent 5″ Insulated Tee Bracket (sold separately) is required when mounting to a wall.

Description

What a tee does

On a wall exit, the pipe passes horizontally through a wall thimble into the side of the tee, and the chimney continues straight up from the top. The bottom of the tee rests on the tee bracket and is capped, which gives you an easy clean-out.

What makes MightyVent different

  • Fully insulated junction. Ceramic fiber surrounds the flue through the whole tee, including the branch.
  • Insulated clean-out cap with drain. The cap is insulated too, comes off for sweeping, and has a 3/4″ NPT threaded drain with a stainless plug.
  • 304 stainless inside and out. The inner wall stands up to flue-gas moisture and creosote, and the polished outer wall stands up to weather.
  • Clamps included. The tee and the cap each come with a clamp, so assembly is quick and the cap comes off easily for cleaning.
  • UL listed. Part of the MightyVent UL 103 Type HT chimney system.
