Lubricating the gas cocks

turn and get blocked. Clean them internally and
replace the lubrication grease.
Gas types and Countries
It is possible to identify the available gas types based on the country the appliance is to be installed
in. Refer to the heading number to identify the correct values in the “Burner and nozzle characteristics
tables".
Burner and nozzle characteristics tables
Following adjustment to a gas other
than the one originally set in the factory,
replace the gas setting label on the
appliance with the one corresponding
to the new gas. The label is inserted
inside the nozzle pack (where present).
Lubrication of the gas cocks should be
performed by a specialised technician.
