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 tables (pag. 37, 38). 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. 21, 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. 21, 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. 22 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. 23 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.
REGULATIONS AND SUBSTITUTION FOR USING A
DIFFERENT GAS THAN THE TYPE PROVIDED FOR
Functioning with different gas than the type provided for.
For changing to another type of gas it is necessary to substitute the nozzle in the main burners and
in the pilot burner, following the indications given in the following paragraphs. The type of nozzle
to install can be found in tables 2-3-4-5-6 (pag. 23-24). The nozzles for the main burner, marked
with the relative diameter in hundredths, and the ones for the pilot burner, marked with a number,
can be found in a transparent packet attached to the instruction booklet. When the conversion is
completed, check the tightness of the pipe fittings and also that the ignition and functioning of both
pilot burner and main burner, at both minimum and maximum, are correct. It may be necessary to
check the output (power).
Then, modify the technical sheet (fig. 5, page 4) and place in the position H the sheet relevant to the
new gas delivered as standard equipment.
