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. 20, 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. 21 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. 22 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. 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. 3- pag.4) and place in the position H the sheet relevant to the
new gas delivered as standard equipment.
Substituting the burner nozzle (figg.11, 12 – pag.5)
To substitute the nozzle of the burner, first of all it is necessary to remove the knob (1), the drip
pan (2), and the control panel (3). After clearing the work area, loosen the screw which blocks the
primary air regulating bush (5) and open it completely; unscrew the nozzle (6) with a spanner and
substitute it with a suitable nozzle for the type of gas used, shown in tables 2, 3, 4, 5, 6. Reassemble
the nozzle,, tightening it well and proceed with regulating the primary air, as indicated in the next
paragraph. When all this is done, replace the parts removed previously.
Regulating the primary air of the burner (fig. 12 – pag.5)
After having substituted the burner nozzle, the primary air must be regulated; to do this, loosen the
screw (4) which fixes the bush (5), bring value X to the correct measurement, referring to tables 2,
3, 4, 5, 6, tighten the screw (4) and check the accuracy of value X.
