Fume duct material:
The tubing must consist of 0,5 mm thick rigid stainless steel,
with fastening joints 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 may damage the unit.
Output “T-tube”:
Always attach a regulator "T-tube" to the output of the boiler.
Windproof terminal:
A windproof terminal must always be installed to avoid the
backflow of fumes.
Chimney draught:
The figures below show three standard diagrams, specifying
adequate lengths and diameters. Any other type of installation must guarantee a
draught of 10 Pa (0,10 mbars) measured when hot and at the maximum power.
Ventilation:
To ensure the boiler's optimum operation,
the installation location
should be fitted with an air vent, with a minimum cross-section of 100 cm
2
,
preferably close to the unit's back panel. The boiler includes a circular pipe
(Ø 50mm) that may be routed to the exterior of the house.
If there is an air extraction system in the home (kitchen extractor), it will be
necessary to have a ventilation section that is larger and better sized than
the various pieces of equipment that extract air from the home.
Placing the boiler in places where kitchen extractors or gas extractors are
installed may affect the proper operation of the boiler.
SZM A PLUS range boilers must not be operated in condensing conditions.
