INSTALLATION INSTRUCTIONS
FLUE SYSTEM
The stove must be connected to a suitable and efficient flue that provides a good updraught to safely take the products of combustion (fumes) from the stove outlet to the outside air. To ensure a good updraught it is important that the flue gases are kept warm and that the flue size suits the stove.
The termination of the outlet at the top of the flue also needs to comply with the Building Regulations. The minimum effective height of the chimney must be at least 3 metres and when warm the flue draught should be between 0.05 and 6mb (0.5mm to 6mm water gauge).
The stove requires a minimum flue size of 125mm (5 inches). The stove can be fitted to a sound conventional solid fuel burning chimney system (Class 1) provided it is swept.
If the chimney is not sound or the chimney has an internal flue size greater than 225mm (9 inches) diameter or 200 x 200mm square, a 125mm (5 inches) diameter stainless steel flexible flue liner complying with BS 715 should be installed in the flue.
If a new chimney is being provided it should fully comply with the relevant Building Regulation Requirements and BS 5440: Part 1. Suitable types of chimney include the following.
•Masonry chimney built with clay or concrete lin- ers, or a chimney block system meeting Building Regulations.
•Precast concrete gas flue block complying with BS 1289: Part 1
Factory made metal chimney complying with BS 715 (often called "Twin wall Class 2 chimney") or Factory made metal insulated chimney comply- ing with BS 4543: Part 2 (often called "Class 1 pre- fabricated metal chimney"). To ensure the flue gases are kept warm an insulated chimney system should be used if the chimney is positioned outside the building.
The flue must be terminated with a suitable chimney pot or cowl and the chimney or flue shall be swept prior to installation unless the chimney is clean and unobstructed.
The flue and chimney installation must be carefully checked by a competent person before fitting the stove to ensure it is suitable and will work safely. The flue must also pass a Flue flow test (smoke test) to BS 5440: Part 1.
