The Story

The Ariston Vertical Starter (Part No. 3318079) is the boiler-connection adaptor piece required whenever a vertical coaxial flue kit is fitted to an Ariston boiler range. It connects the boiler's exhaust manifold to the vertical flue assembly above, redirecting the flue gases upward through the ceiling and roof. The Ariston Vertical Flue with Red Terminal (Part No. 3318081) is the complete 80/125 mm vertical flue terminal pipe that pairs with the vertical starter — it includes a weatherproof red terminal cap designed to be visible above the roof line for easy identification. Both parts use the standard push-fit coaxial connection common across Ariston's HE boiler flue range.

⚠ Both Parts Are Needed for Vertical Installation: For a complete vertical flue installation, you need both the Vertical Starter (3318079) and a Vertical Flue Kit (3318080 with black terminal, or 3318081 with red terminal). Neither part is functional on its own. The starter connects to the boiler; the flue kit terminates above the roof.

Frequently Asked Questions
What is the difference between the red terminal (3318081) and the black terminal (3318080) vertical flue kit?
Both kits are mechanically identical. The difference is purely aesthetic — the 3318081 has a red-coloured weatherproof terminal cap, while the 3318080 has a black cap. Red terminals are sometimes preferred for visibility on tiled roofs; black for slate or dark-toned roofing materials. There is no functional performance difference between the two.
Can the vertical flue kit be used on flat roofs?
Yes. The vertical flue kit is suitable for both flat roofs and pitched roofs. A flat roof flashing plate (Part No. 3318011) is required for flat roofs. For pitched roofs, flexible base cap flashings are available in two angle ranges — 3318009 (12–40°) and 3318010 (Red, 12–40°). These are sold separately and must be ordered in addition to the flue kit and starter.
Do I need to cut the vertical flue kit to length?
Do not cut the vertical flue kit. The terminal height above the roof line is fixed to ensure correct clearance above the flashing. Usable length variation is accommodated by the kit's design. To increase total run height, use a coaxial extension pipe between the vertical starter and the flue kit.
What diameter roof hole is required?
A 130 mm diameter hole should be cut through the ceiling and/or roof to accommodate the Ø60/100 coaxial vertical flue assembly. Mark the centre position on the ceiling based on the distance from the boiler's back wall to the centre of the flue outlet, as shown in the installation manual dimensions diagram.
