Checking the power
Normally, it is sufficient to check that the nozzles installed are the right ones and that the burners
function properly. If desired, further check the power absorbed by using the "Volumetric Method".
With the help of a chronometer and a counter, it is possible to read the volume of gas output to the
appliance in time units. The right comparison volume [E] can be obtained with the formula shown
overleaf in litres per hour (l/h) or in litres per minutes (l/min), by dividing the nominal and
minimum outputs (power) shown in the table of burner features for the lowest heat capacity of the
type of gas foreseen for use with the appliance. This value can be found in the norm tables or can be
provided by the local gas supply company.

Heat capacity
The reading must be done when the appliance is already in function.
Checking pilot burner
Check the flame of the pilot burner, which must be neither too short nor too high but must lap the
thermocouple and have a sharp form; otherwise, it is necessary to check the size of the nozzle
depending on the pilot version, as specified in the following paragraphs.
Checking regulation of primary air
All the main burners are provided with primary air regulation. Checking must be done observing the
values shown in the air regulation column of the burner features table. To regulate the primary air,
proceed as illustrated in the following paragraphs.
ATTENTION! All the parts, protected and sealed by manufacturer may not be regulated by
the installer if not specifically indicated
Joining appliances
Once the levelling and connection operations have been completed, the appliances can then be
joined together. Unroll the sealing strip (1), which is included in the joining the kit inside the
appliance, and stick it to the end of the work surface, about 2-3 mm from the edge (fig. 19, p. 7).
Once this has been done, place the units together, remove the instrument panels by unscrewing the
two fixing screws and then insert an M6 screw, together with a washer (provided with the joining
kit), into the threaded hole (2) (fig. 19, p. 7). Tighten the screw well using a suitable key.
Then check the level (3) along the back edge of the units, as shown in fig. 20 on page 7 place the
joining plate (4) on the raised part of the unit tops and fix the M6 screws with an Allen key (6)
(supplied with the provided kit).
Once the joining plate (4) has been fixed to the appliances, fine adjustment of the joint can then be
made with the grub screw (7), located on the joining strip. This should be tightened well with an
Allen key (8), as shown in fig. 21 on page 7.
Once the joining operation has been completed, position the stainless steel joining plate cover (9)
and fix it in place with an M4 screw (10) using a Phillips screwdriver (11).
Remove any traces of trimming that can be seen between the devices with a scraper.
