If this happens:
• check the type of gas/pressure used: it must correspond to that indicated on the appliance plate;
• check for any shifting of the burner parts (flame divider, cap), due to assembly of the appliance.
If the problem persists, contact Technical Assistance.

6. Ventilation

This appliance is not connected to a device for the evacuation of the combust products. Therefore, it must
be connected in compliance with the installation standards in force. Pay particular attention to that envis-
aged by local legislation on the matter of ventilation ad aeration.
Specifically (UNI 7131), the room where the appliance is installed:
• must be fitted with a system to take the combustion fumes outside, through a hood or electric fan
which starts operating automatically every time the appliance is switched on;
• it must have a system which allows the air flow necessary for proper combustion (at least 2 m3/h for
each kW of installed power). This can be obtained by taking the air directly from outside (section of at
least 100 cm2, in order to prevent it becoming accidentally blocked), or indirectly from adjacent rooms
(not bedrooms or rooms where there is a risk of explosion) which are directly ventilated and connected
to the former by permanent openings.
The appliance is fed by LPG (liquid petroleum gas). LPG is heavier than air, so it settles downwards. Conse-
quently LPG bottles must have an opening towards the outside to allow low-level evacuation of any gas
leaks. Empty or partially full LPG bottles must not be installed or kept in rooms or areas that are below
ground level (cellars, etc.).
Gas bottles that are being used may be kept in the same rooms/area, in a position where they are not sub-
ject to the direct action of sources of heat (50°C).

7. Adjustments and transformations

No adjustment is necessary:
• the burners are fixed primary air burners;
• as the only power supply is LPG (in compliance with that indicated on the plate on the underside of the
appliance), the minimum levels have already been set in the factory. The valve by-pass screw has al-
ready been fully tightened. Should an inadequate flame be found in the Minimum position during use,
intervention on the by-pass valve screw is forbidden. Check the conditions of the system (any narrowing
of the connections; the appliance supply pressure is stated on the plate) or of the pressure regulator fit-
ted to the gas bottle.
WARNING! The appliance is in category one (I3+ or I3B/P), so no transformation for use with
other types of gas is possible. The dismantling of the injectors for switching to other types of gas
is not allowed.
