• If you use a tube to allow for the combustion airflow intake from the outside, this should not have more
than 60cm long horizontally, and an internal diameter equal or greater than the unit's tube diameter. The
connection path must be straight (without bends).
• If the house is equipped with a air exhaust system (e.g. kitchen extractor fan), a top ventilation section
must be installed, suitable to accommodate the different air exhaust systems existing in the household.
• Installing the unit in locations near kitchen exhaust fans or fume extractors may prevent the correct
operation of the unit and, in certain situations, may cause the inversion of the chimney draught flow
which will expel the fumes into the room where the unit is installed.
4.2
Installing with a chimney
• As shown in the following figure, the installation of the unit brings the exhaustion tube directly onto the
chimney. If the chimney is too large, an 80 mm-wide pipe should be installed at the fume outlet.
• A T connection must be attached to the base of the tubing, to allow for periodic inspections and annual
maintenance.
• We recommend that you do not use the unit in adverse weather conditions that may seriously impact the
draught (particularly with very strong winds).
• Before lightening the fore, you must make sure that the chimney tubing is free from obstructions.
Otherwise, the fume can be blown into the room where the unit is installed.
