The Story

The Ariston 45° Coaxial Flue Elbow Pack (Part No. 3318076) contains two 45-degree bends for the standard Ø60/100 mm coaxial flue system, compatible with Ariston's E-Combi EVO, E-Combi ONE, Clas ONE, Genus ONE, and Alteas ONE boiler ranges. Two 45° bends combine to achieve the same directional change as a single 90° elbow but with a gentler, lower-resistance flue path and a smaller effective flue-length deduction — making them preferable where the maximum permissible flue run is limited. All connections are push-fit with integral lip seal; no tools or clamps are required to join the components.

ℹ Lower Flow Resistance Than 90° Elbows: Two 45° bends in series produce the same 90° direction change as a single 90° elbow but with a smoother flue gas flow path. This typically results in a smaller deduction from the maximum permissible flue length — beneficial on installations close to the maximum run limit. Check your boiler's installation manual for the exact reduction factor for 45° vs 90° bends.

Frequently Asked Questions
Why buy a 45° bend pack instead of a single 90° elbow?
Two 45° bends offer a shallower change in direction which reduces flue gas turbulence and resistance compared to a sharp 90° turn. This means a smaller effective deduction from the maximum permissible flue run, giving the installer more flexibility on installations with longer or more complex routes. Two 45° bends can also be used independently for separate 45° changes of direction.
Are both bends in the pack identical?
Yes — both bends in Part No. 3318076 are identical 45° coaxial elbows. They can be used together to make a 90° turn (with a short straight section between if required) or used individually in separate locations on the same flue run.
Is there a silver version to match the Alteas ONE NET?
Yes. For installations where the flue pipework is visible and the silver Alteas ONE NET aesthetic is preferred, the equivalent silver 45° elbow pack is Part No. 3319168. This is mechanically identical to 3318076 — the difference is colour only.
Do I need any sealant or clamps when fitting these elbows?
No sealant or clamps are required. Ensure the lip seal is correctly positioned in the socket before pushing the elbow onto the adjacent flue piece. The push-fit connection is gas-tight when fully engaged. Support brackets (Part No. 3318015) should be used at regular intervals along the flue run.
