Box 'F' - Single Skin Square Fluebox

Our Box 'F' is a single skin gas flue box designed to be fitted into an existing fireplace back panel opening and comes with a flange around the face to allow the box to be sealed to the back panel.

All our flue boxes are manufactured to BS715  2005 and suitable  for fires complying with BS 7977-1  2002

It comes as standard with our specially designed easy fix collar so a standard 5" flexible flue liner can be attached after fixing the box in situe. It also incorporates wire fixing tabs at the rear for use with fires that have wire fixings.

As this box is designed to be fitted to an existing fireplace or after an installation you are advised to check our technical drawings against the fires specification data as the inside dimensions are reduced in this model compared to our other boxes.

All our flue boxes and components are designed by our own Gas Safe and Hetas registered installers with a combined experience of over 70 years and who use these boxes themselves every day.
