E.6.1.5Gas pressure regulator
• The section of the gas supply line must be sufficient to
ensure the gas flow necessary for full operation of all the
appliances connected to the system.
If the gas pressure is higher than that specified or is difficult to
regulate (not stable), install a gas pressure regulator (acces-
sory code927225) in an easily accessed position ahead of the
appliance. The pressure regulator should preferably be fitted
horizontally, to ensure the right outlet pressure:
1 connection side gas from mains
2 pressure regulator
3 connection side gas towards the appliance
The arrow on the regulator ( ) indicates the gas flow
direction.
C CA AU UT TIIO ON N
These models are designed and certified
for use with natural or propane gas. For
natural gas, the pressure regulator on the
header is set to 8” w.c. (20 mbar).
A AU US ST TR RA AL LIIA A: the gas pressure regulator supplied with the
appliance must be fitted to the appliance inlet. Adjust the test
point pressure with one burner operating at maximum setting
as follow:
• 0.74 KPa for Natural gas
• 1.50 KPa for Propane gas.
E.6.1.6Conversion to another type of gas
Nozzle Table “B“ (see handbook Appendix) gives the type of
nozzles to be used when replacing those installed by the
manufacturer (the number is stamped on the nozzle body).
At the end of the procedure, carry out the following check-list:
C Ch he ecckk O Okk
burner nozzle/s replacement
correct adjustment of primary air supply to
burner/s
pilot nozzle/s replacement
minimum flame screw/s replacement
correct adjustment pilot/s if necessary
correct adjustment of supply pressure (see
technical data/gas nozzles table)
apply sticker (supplied) with data of new
gas type used

E.6.2.1Supply pressure check (all versions)
Make sure the appliance is suitable for the type of gas
available, according to that given on the dataplate (otherwise,
follow the instructions given in E.6.1.6 Conversion to another
type of gas paragraph of this section).
The supply pressure must be measured with the appliance
operating, using a pressure gauge (min. 0.1 mbar).
• Remove the control panel.
• Remove screw “A“ from the pressure point and connect the
pressure gauge “O“.
• Compare the value read on the pressure gauge with that
given in Table “B“ (see handbook Appendix).
• If the pressure gauge gives a reading outside the range of
values in Table “B“ , do not switch the appliance on. Consult
the gas company.
E.6.2.2Gas valve outlet pressure adjustment
Refer to the picture above
• Remove the retaining screw from pressure point “B“ and
connect the pressure gauge tube.
• Feed the appliance with the correct nominal gas pressure
as specified in the paragraph E.6.2.1 Supply pressure
check (all versions).
• Start the fryer as indicated in the chapter F instruction for
the user.
• Turn gas valve “D“ outlet pressure adjustment screw
clockwise to increase the pressure and anticlockwise to
decrease it, adjusting the pressure as specified in the
nozzle table “B“ (see handbook Appendix).
E.6.2.3Checking the primary air supply
When the primary air supply is correctly adjusted, the flame
does not “float“ with burner cold and there is no flareback with
burner hot.
• Undo screw “A“ and position aerator “E“ at distance “H“
given on the Table “B“ (see handbook Appendix).
