INSTALLATION INSTRUCTIONS
WARNINGS
Installation, adjustments and maintenance of the
appliances must be done by authorized installers, in
accordance with the safety standards in force. The
manufacturer declines any responsibility if such
obligation is not observed.
INSTALLATION
Positioning
–The overall/connection dimensions and the technical
data are stated in the pages in the appendix.
–Install the appliances only in sufficiently aired rooms.
–Fryers are type “A1” appliances and for this reason
the rooms must be ventilated in accordance with the
technical standards in force.
–Position appliances at least 10 cm from the nearby
walls. Such distance can be less when the walls are
incombustible or protected by a thermal insulator.
–The appliances are not suitable for built-in
installation.
Assembly
–Remove the film which protects the external panels.
Any glue remaining on these is to be removed with a
suitable solvent.
In line union of the appliances
–Put the appliances next to each other and level them at
the same height.
–Unite the appliances using the special union joint-
coverings supplied upon request.
Connection to the gas piping
–Before carrying out the connection consult thegas
delivery body.
–Install a fast-closing cut-off cock upstream from the
appliance in an easily accessible place.
–Check if the appliance is set for the type of gas with
which it will be fed. If it is not, read paragraph
“Adaptation to another type of gas”.
–Check for any leaks in the connection points.
Oil drainage
–Oil drain cock against accidental opening during
operations. To drain oil from well press the cock
command lever downwards an at the same time pull it
forward.
–A drainage extension with bayonett clutch is foreseen.
Important: The container used for well drainage must
be large enough and of heat resistant material.
CONVERSION TO ANOTHER TYPE OF GAS
To adapt appliances to work with other types of gas
carry out all the operations stated below. Nozzles and
adhesive labels are in the bag supplied with the
appliance.
Replacement of nozzle and burner primary air
adjustment (Fig. 1)
- Remove the panel under the oven door.
- Slacken grub screw V,undo injector U and remove
together with aerator Z.
- Replace the injector with the one indicated in Table
T1 and screw down together with the aerator.
- Position aerator Z at distance A as indicated in Table
T1.
- Retighten grub screw V and seal with red paint.
Replacement of pilot burner nozzle (Fig. 2)
–Remove control panel of appliance.
–Unscrew closing plug R. Unscrew nozzle UP and
change it with the proper one indicated in Table T1.
–Screw down closing plug R.
Replacement of gas preset adhesive label
–Apply the correct adhesive label which indicates the
new type of gas for which the appliance is now set.
START-UP
Function check
–Start-up the appliance according to instructionsfor use
and check the regularity of the burner ignition, the
absence of gas leaks and the efficiency of the burnt gas
exhaust system.
–If necessary consult paragraph “Analysis of several
failures”.
Nominal heat input check
–After installation or adjustment to another type of gas
and at each maintenance intervention check the heat
input of the appliance.
–The nominal heat input is stated in the “Technical
data” Table T5.
–The appliance operates at the nominal heat input
when the nozzles assembled are suitable for the type of
gas used and the inlet pressure is the one indicated in
Table T1.
–For the measurement of the inlet pressure read
paragrah “Inlet pressure check”.
Inlet pressure check (Fig.3)
–For the measurement of the inlet pressure use a gauge
having a minimum definition of 0.2 mbar.
–Remove control panel of appliance, remove seal
screw PP from upstream pressure tapping and connect
the gauge pipe.
–Carry out the measurement with appliance on.
–If the value is not within the limits indicated in Table
T3, interrupt the operation of the appliance and contact
the gas delivery body.
Disconnect the gauge pipe and screw down seal screw
PP.
