ExamPlES oF CoRRECt CoNNECtIoN to thE ChImNEy
In the presence of type B gas appliances with intermittent operation not intended for heating, they must have their own aeration and/or
ventilation opening.
The air inlets must meet the following requirements:
they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
they must be made so as to make the maintenance operations possible;
positioned so that they cannot be obstructed;
The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and
ventilation), as long as the flow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a fire hazard, bathroom,
bedroom or common room of the building.
flue gas eXhaust
The heat generator works in depression and is equipped with an outlet fan for flue gas extraction. There must be a single exhaust system for
the generator. Using a flue that is shared with other devices is not allowed.
The components of the flue gas exhaust system must be chosen in relation to the type of appliance to be installed in compliance with:
UNI/ TS 11278 in the event of metal chimneys, with particular attention to that stated in the specification;
UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, UNI EN 1806 in the event of non-metallic chimneys.
The length of the horizontal section must be minimal and, in any case, no longer than 3 metres, with a minimum upward slope of 3%
There must not be more than 4 direction changes including the one due to the use of the "T" element.
A “T” fitting with a condensation collection cap must be provided at the base of the vertical section.
If the exhaust is not inserted in an existing flue, a vertical section with a windproof end piece is required (UNI 10683).
The vertical duct can be inside or outside the building. If the smoke duct is inserted in an existing flue, it must be certified for solid fuel.
If the smoke duct is outside the building, it must always be insulated.
The smoke ducts must have at least one airtight inlet for flue gas sampling.
All the sections of the flue gas duct must be accessible to inspection.
Inspection openings must be provided for cleaning.
If the generator has a fume temperature lower than 160°C+ ambient temperature caused by the high yield (contact technicians) it
MUST be resistant to humidity.
ChImneY Cap
The chimney caps must meet the following requirements:
they must have a useful outlet section no less than double that of the chimney/ducted system on which it is installed;
they must be adapted in order to prevent the penetration of rain and snow in the chimney/ducted system;
they must be built so that, in the event of winds coming from all directions and from any angle, the expulsion of combustion products
is in any case ensured;

ConneCtIon to the maIns eleCtrIC supplY
The generator is supplied with an electric power cable to be plugged into a 230V 50 Hz socket, possibly with a circuit breaker switch. The
socket must be easily accessible.
The electrical system must be compliant with standards. The efficiency of the earthing circuit must be checked. Unsuitable earthing of the
system can cause malfunctioning for which the manufacturer will not be held liable.
Power supply variations beyond 10% can cause faulty operation of the product.
