Viessmann 60/100 45 Degree Flue Bend Pair | 7373227

Description

The Viessmann 60/100mm 45° Flue Bend is supplied as a matched pair, giving installers the flexibility to offset a flue run around an obstruction or to angle a horizontal terminal away from an awkward wall position — without resorting to a full 87° elbow.

Used in combination, the two 45° bends let the flue path step sideways or vertically while keeping the overall run within the maximum permitted length for the connected Vitodens boiler.

🛈

Please Note: This flue system has been tested and CE-designated as one structural unit with the Vitodens boiler range in accordance with DVGW-VP 113. Only this flue system may be used together with compatible Vitodens boilers, and mixing components from other manufacturers' flue systems is not permitted.

Sold as a matched pair

Two 45° bends are supplied together, letting the flue offset and return to line around a single obstruction.

60/100mm concentric diameter

Matches the standard Vitodens balanced flue diameter, so it integrates directly with horizontal and vertical flue kits in the same range.

Rigid, durable construction

Manufactured to the same specification as the rest of the Vitodens flue range for a long service life in both horizontal and vertical installations.

Flexible routing

Ideal for routing a flue around joists, beams or structural obstructions where a straight run isn't possible.

Reduces total elbow count

Two 45° bends can often replace a pair of 87° elbows in an offset run, helping to preserve available flue length.

Simple push-fit assembly

Connects using the same push-fit jointing method as the rest of the concentric flue range for quick, reliable assembly.

Why would I choose two 45° bends instead of one 87° elbow?

A pair of 45° bends allows the flue to offset sideways and then return parallel to its original direction — useful for stepping around a joist or beam — whereas a single 87° elbow only changes direction once.

Does using bends reduce the maximum permitted flue length?

Yes. Each bend has an equivalent length that counts against the maximum permissible flue run for the specific Vitodens boiler model — check the boiler's installation manual for the exact allowance.

Can this be used on both horizontal and vertical flue runs?

Yes, 45° bends of this diameter are used across both horizontal and vertical Vitodens flue configurations wherever a directional change is needed.
