2.7 FLUE LENGTHS
Flue length = 0.75 m (not including the terminal, which is supplied with the boiler)
Note: Additional flues (of the same length) are available.
Length of Flue Required:-
Rear Flue = wall thi195 mm
Side Flue = wall thi distance between wall and side of X mm (L/H side X = 140, R/H side X = 380)
Vertical Flue = distance from top of boiler side panel to required roof position minus 1 m for vertical terminal assembly
Maximum flue length = 4 m horizontal or 4 m vertical.
Each additional 90° Bend is equivalent to 1 m of flue length.
Each 45° Bend is equivalent to 0.5 m of flue length.
The Vertical Flue terminal assembly is equivalent to 1 m of flue length.
