Side view of the installation without chimney, example of the inspection point
Fume duct material: the tubing to be used for this installation must consist of 0,5 mm thick
rigid stainless steel, with fitting bindings attaching the different sections and accessories.
Insulation: the fume ducts must be double-walled and insulated to make sure that fumes do
not cool down going outwards, which would cause an inadequate circulation and condensation
that might damage the unit.
Output T connection: always attach a "T-tube" with damper to the output of the unit.
Swing type check valve: always install this system to avoid fumes backflow.
Draught in the chimney: the figure below shows three standard diagrams, specifying the
adequate lengths and diameters. Any other type of installation must guarantee a draught of
12 Pa (0,12 mbars) measured when hot and at the maximum power.
