Failure to comply with these requirements may prevent the correct operation of
the boiler. Follow all the instructions shown on the diagrams.
Because the boilers operate with the combustion chamber in draught it is an
absolute requirement to install a fume exhaust pipe to allow for the proper extraction
of the combustion gases.
Fume duct materials: The tubing must be made of 0.5mm thick rigid stainless steel,
use with pipe fittings to attach different sections and accessories.
Insulation: The fume ducts must be double-wall and properly insulated to make sure
that fumes do not cool down going outwards, which would cause inadequate
circulation and condensation that may damage the unit.
Out T-tube: Make sure you attach to the boiler output a fitting T-tube.
