Checking the pilot light
When correctly adjusted, the pilot light flame will com-
pletely surround the thermocouple and will not flicker.
Checking the primary air
The appliance can be adjusted. Air volume flow is cor-
rect when there is sufficient protection against the fla-
me rising when the burner is cold or light-back when it
is hot. Position the ring at measurement “A” (Fig. 1) in-
dicated in table 1 for type of gas.
Checking the functions
- Start the appliance in accordance with the instructions;
- Check the gas tubes for leaks;
- Check that the flame on the main burner lights
properly and is correctly formed, even on low;
- Check that the pilot light is correctly regulated;
- Draw up a servicing and maintenance contract.
Note for the installer
- Explain and demonstrate to the user how the machi-
ne works according to the instructions, and hand him
this manual.
- Remind the user that any structural alterations to the
room housing the appliance may affect the combu-
stion air supply. Once the alterations have been com-
pleted, the appliance and its functions should be tho-
roughly checked.
Running the appliance on other types
of gas
When changing to another type of gas, e.g. from natural
to LP, or to another gas group, consult the “TECHNICAL
DATA” table to determine the correct nozzles to use.
The nozzles for the main burners and pilot light for diffe-
rent types of gas, marked in 100ths of mm, are in a ca-
se supplied with the appliance.
When the appliance has been transformed or adapted,

Main burner injector replacement
(Fig. 1)
To replace the injector (30) dismount the front panel.
Dismount the holding injector collector unscrewing the nut
31 and the nut 32 on the gas cock. With a 12 spanner un-
screw the holding injector and replace them with new one
(see schedule “technical data”). Reassemble in the rever-
se order.
Pilot injector replacement (Fig. 2)
To replace the pilot injector (36) dismantle the front panel
with a screwdriver and unscrew the screw nut (35), now the
injector can be reached inside the body pilot, replace it
with a new one (see technical data) when finished screw
again the screw nut (35).
Adjusting the low flame (Fig. 3)
Referring to the “TECHNICAL DATA” table, set the low fla-
me screw (2) as follows:
- if the appliance is to run on LP gas, tighten the low flame
screw as far as it will go;
- if the appliance is to run on natural gas, turn the low fla-
me screw while simultaneously adjusting the primary air:
- read off the setting in It/min which corresponds to the
heat value (calculated by the “Volumetric Method”) in
the Gas Flow Setting Table (2); start the appliance up
according to the instructions;
- after allowing the appliance to run for same mins., turn
the knob to low and set minimum gas flow by turning
screw (2) (to the right = gas flow decreases; to the left =
gas flow increases).
MAINTENANCE
The following maintenance programme should be carried
out at least once a year:
- Check that all the safety and setting devices are working
properly;
- Check that the burners are working properly with regard
to:
- ignition
- combustion safety;
- Check the functions of the appliance as described in pa-
ragraph "Checking the functions".
