The challenge

Three ovens in a working factory hall needed new flues, and the old flue had to come out first.

The install was planned in three phases, with a weekend day allowed for.

Each oven outlet needed its own bespoke adaptor.

What we did

We surveyed the hall and drew the routes in CAD.

We stripped out the existing flue and fitted three new Ø150 twin wall insulated flues.

Three bespoke adaptors connect the flues to the ovens.

The runs cross the hall at high level on the building steel, then rise through the roof to mesh terminals.

The result

The last oven was connected on 9 December 2024, after we moved a section of ductwork to make room for its horizontal.

Brackets tight and capped, and the site swept and left tidy.

Certificate of conformity issued on 10 December 2024.
