Failure to comply with these requirements may prevent the correct operation of the
unit. Follow all the instructions presented on the diagrams.
The Alpes and Douro units operate with the combustion chamber in vacuum, so it is
absolutely necessary to have a fume exhaust pipe to extract combustion gases properly.
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 to the output of the unit a "T-tube" with a regulator.
Windproof terminal:
A windproof terminal must always be installed to avoid the
backflow of fumes.
Draught in the chimney:
The figures below show three standard diagrams, specifying
adequate lengths and diameters. Any other type of installation must guarantee a draught
of 12 Pa (0.12mbars) measured when hot and at the maximum power.
Ventilation:
To get the optimum operation of the unit it is necessary that the installation
location has an air inlet with a minimum section of 100cm
2
, preferably near the back
panel of the unit. The free standing pellet fire unit has a circular pipe (
50mm) that may
be connected to the exterior of the house.
If the residence has an air exhaust system installed (e.g. kitchen extractor fan), a
top ventilation section must be installed, suitable to accommodate the different air
exhaust units systems that exist in the house.
The installation of the unit on locations near kitchen exhaust fans or fume
extractors may prevent the unit from operating properly.
