• Changing the pilot nozzle (19):

inserting it and the small pilot connecting pipe in the nozzle holder together.
Check that there are no gas leaks by using a soapy water solution.
• Regulating the minimum flame:

until you get the minimum flame required.
Adjustment of minimum (Fig.2): (machines set up to use LPG and changed over to
natural gas)
Remove the knob (8) from the cock and use a screwdriver on the adjustment screw (7)
to tighten it all the way down.
• Supply pressure:
it must be that specified on the appliance’s data plate and in the instruction handbook
(see the Technical Data table). Check the supply pressure by inserting a rubber pipe,
with a water gauge or similar, in the pressure tap (10) welded on the gas shaft (9)
removing the screw (11). After it has been checked, tighten the screw. If the supply
pressure is different to that specified, find the cause and correct it.
