Checking the pilot light
When correctly adjusted, the pilot light flame will comple-
tely surround the thermocouple and will not flicker; if it
does, make sure that the nozzle is the correct one for the
type of gas used.
Checking the primary air
The plates, whether smooth or grooved, can be adjusted.
The air flow is correctly adjusted when there is adequate
protection against the flame rising when the burner is cold
or flareback when it is hot.
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 machine
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 combustion
air supply. Once the alterations have been completed,
the appliance and its functions should be thoroughly
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” 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 case
supplied with the appliance (the pilot burner nozzles are
marked with a code number).
When the appliance has been transformed or adapted,
recheck its functions as described in paragraph
"Checking the functions".
Replacing the main burner nozzle
To change nozzle (30), pull out the fat tray and loosen the
fixing screws holding the control panel in place.
Remove the panel. Unscrew the nozzle from the nozzle
holder with an adjustable spanner; replace with a new
nozzle (see “TECHNICAL DATA” table).
To make changing the nozzle easier, loosen screw (39) to
push the air adjustment sleeve back.
After fitting the nozzle, reset primary air distance “A” (see
“TECHNICAL DATA” table).
Replacing the pilot burner nozzle
(Fig. 5)
To get at the pilot burner, slide out the fat tray and remove
the control panel (as previously described).
The pilot burner has a fixed gas supply.
To change to another type of gas, replace the nozzle on
burner (36) according to the type of gas used, by loosen-
ing hose (35) (see “TECHNICAL DATA” table).
Adjusting the low flame (Fig. 3)
Referring to the “TECHNICAL DATA” table, set the low
flame screw (36) 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
flame 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
