DuraVent 4" PelletVent Pro 90° Elbow

Turn your 4" pellet vent run a full 90° — horizontal to vertical, or around a corner.

The 90° elbow changes the run's direction, most often where the pipe leaves the stove or a tee and turns up an outside wall, or where a vertical run turns out through the wall. Each bend adds resistance and counts toward your stove's maximum equivalent vent length, so use as few as the layout allows. Factory-sealed seams; Black or Galvalume finish.

Pair it with DuraVent 4" PelletVent Pro pipe lengths and the 4" clean-out tee.

About PelletVent Pro: DuraVent PelletVent Pro is double-wall Type L/PL pellet vent — a stainless steel inner wall inside a Galvalume outer wall, listed to UL 641 with 1" clearance to combustibles in the USA and rated for continuous flue temperatures up to 570°F. It is made for stoves and inserts burning wood pellets, corn and other biofuels, or oil. DuraVent parts use a twist-lock joint that connects only to other DuraVent PelletVent Pro components — they will not join another brand's pellet vent, so build the whole run from PelletVent Pro.

3" or 4"? ComfortBilt notes that 4" venting allows longer runs than 3", and recommends 4" on its stoves when the flue height is over 12 ft, above 5,000 ft elevation, or when the layout goes past the 3" vent-length limit. Your stove's manual sets the size it requires. Stepping up from a 3" flue collar? Start with the DuraVent 3" to 4" PelletVent Pro increaser. Shop all pellet stoves.
