Note 1	Height minimum 2 meters above roof surface and any roof of any buildings in a distance of 100 meter or according to local requirements. For gas combustion these recommendations can often be less restrictive.
Note 2	Chimney should be supported sufficiently at bottom and at top based on strength calculations performed. Insulation thickness (2 x) according to local requirements, to be added the necessary diameter "B".
Note 3	Flue pas piping to be as short as possible, and bends as few as possible - preferable maximum two bends in the flue gas piping. Angel of bends to be minimum 120° everywhere.
Note 4	Above heat capacities are net output, based on AB&CO high standard efficiencies. Diameters given are approximate value. In case of doubts, use a size higher.
