Kitchen ventilation
The air flow into the room where the appliance is installed
must equal the quantity of air that is required for regular
combustion of the gas and for ventilating the same room.
Air must be taken in naturally through permanent apertures
made in the outside walls of the room or through single or
branching collective ventilation ducts in compliance with the
standards in force. The air must be taken directly from the
outside, from an area far from sources of pollution. The
ventilation aperture must have the following characteristics
(fig.3A):
· total free cross section of passage of at least 6 cm² for
every kW of rated heating capacity of the appliance, with
a minimum of 100 cm² (the heating capacity is indicated
on the rating plate);
· it must be made in such a way that the aperture, both on
the inside and outside of the wall, cannot be obstructed;
· it must be protected, e.g. with grills, wire mesh, etc. in such
a way that the above-mentioned free section is not reduced;
· it must be situated as near to floor level as possible.

permanently ventilated rooms in compliance with provisions
laid down by current regulations and standards. The following
requirements must be observed:
• The appliance must discharge combustion products into a
special hood, which must be connected to a chimney, flue
pipe or directly to the outside (fig.2).
• If it is impossible to fit a hood, the use of an electric fan is
permitted, either installed on a window or on an external
wall, which must be switched on at the same time as the

It may occur that the cooktop does not function or does not
function properly. Before calling customer service for
assistance, lets see what can be done.
First of all, check to see that there are no interruptions in the
gas and electrical supplies, and, in particular, that the gas
valves for the mains are open.
The burner does not light or the flame is not uniform
around the burner.
Check to make sure that:
• The gas holes on the burner are not clogged;
• All of the movable parts that make up the burner are
mounted correctly;
• There are no draughts around the cooking surface.
The flame does not stay lighted on the model with the
safety device.
Check to make sure that:
• You press the knob all the way in;
• You keep the knob pressed in long enough to activate
the safety device.
• The gas holes are not clogged in the area corresponding
to the safety device.
The burner does not remain on when set to "Low".
Check to make sure that:
• The gas holes are not clogged.
• There are no draughts near the cooking surface.
• The minimum has been adjusted correctly (see the
section entitled, "Minimum Regulation").
The cookware is not stable.
Check to make sure that:
• The bottom of the cookware is perfectly flat.
• The cookware is centered correctly on the burner or
electric hot plate.
• The support grids have not been inverted.
If, despite all of these checks, the cooktop does not function
properly and problem persists, call the nearest Merloni Elet-
trodomestici Customer Service Centre, informing them of:
- The type of problem.
- The abbreviation used to identify the model (Mod. ...) as
indicated on the warranty.
Never call upon technicians not authorized by the
