Specifications

If there is no existing chimney then either a prefabricated block chimney in accordance

with Building Regulations Approved Document J or a twin walled insulated stainless steel

flue to BS 4543 can be used. These chimneys must be fitted in accordance with the

manufacturer’s instructions and Building Regulations.

The liner diameter must not be less than 6”. If the draw on the chimney is excessive, a

flue draught stabiliser will help to slow this down. An excessive draw may cause over

firing and thus cause the internal components of the stove to wear out quicker.

Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends

should not be used. Adequate provision e.g. easily accessible soot door or doors must

be provided for sweeping the chimney and connecting fluepipe.
