Chimney
Existing flue

The chimney must comply with the Current Building Regulations. If in doubt, consult your
Dealer or local Building Inspector.

The flue must be in good condition and must provide sufficient draught (refer to technical
details p.

The flue must be suitable for the installation of solid fuel
burning appliances and comply with the Current Building
Regulations.
-
The flue must be clean. It should be swept to remove soot and
dislodge tar deposits.

The flue must be well insulated. If the flue inner wall surfaces
are cold, a good thermal draw is impossible causing
condensation problems (tar formation etc) to occur.

-
The chimney must be at least 4.5 m (15 ft high).
-
In case of a flat roof or when the roof gradient is lower than 15°, the stack must be 1,2 m (4
feet) high at least.
-
If the chimney has any down draught tendency, due to its position in relation to nearby
obstacles, then an anti-down draught cowl must be installed on the chimney or the chimney
height must be increased.
-
If the decompression in the chimney is excessive, a draught stabiliser must
be installed.
