TECHNICAL

The main consideration when choosing a gas fire is what is suitable to go with your existing flue provision. We can certainly help you whether your property has an existing flue, chimney or none at all, as we have choices to suit all these situations.

We therefore provide the following information complete with pictures to explain the different flue types and the alternatives available to you.

For further assistance please call, email or visit our showroom.

CLASS 1
CLASS 1
Common in older houses, earlier than 1960. The Class 1 chimney is identifiable by 7” (180mm) or greater diameter flue. The existing chimney must be structurally sound and checked before installation can be commenced.
CLASS 2
CLASS 2
This chimney type is identifiable by a 5” (130 mm) diameter flue and a steel flue terminal. Usually found in an older house where the existing chimney has been lined or a newer house with a steel flue built in.
PRE-CAST FLUE
PRE-CAST FLUE
Modern houses generally later than 1960 often have a pre-cast concrete chimney system, identifiable by a rectangular box section flue and a terminal, as illustrated in the picture.
NO FLUE
NO FLUE
Modern houses often have no chimney. You can either have an electric fire, or a Powerflue system (allowing a working gas fireplace). The Powerflue option must go an outside wall with suitable room and height.
