Connection With Natural Gas - Lotus CP-94G Operation & Maintenance Instructions Manual

Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.

Connection with natural gas

The connection pressure for natural gas is 1.74 kPa.
THIS APPLIANCE IS EQUIPPED FOR NATURAL (PROPANE) (LP) GAS
This appliance is equipped with orifices sized for operation with natural (PROPANE) (LP) gas.
For conversion to LP (propane) (natural) gas see instruction plate on the appliance.
Orifices necessary for LP (propane) (natural) conversion are provided .*
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.

RULES FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS
Our appliances are tested and regulated with liquid gas (see data plate).
The conversion or adaptation to another type of gas must be carried out by a specialised technician. The nozzles for the
various types of gas are supplied in a packet and are marked in hundredths of mm (see "burners" technical data table).
SUBSTITUTING THE NOZZLE IN THE MAIN BURNER
• Remove the front fixing screws from the panel, remove the start-up cable from the piezoelectric ignition device
• Using a suitable spanner, unscrew the nozzle and substitute it with the right one (see the technical data table).
SUBSTITUTING THE NOZZLE IN THE PILOT BURNER
The flame of the pilot burner has fixed air.
The only operation necessary is the substitution of the nozzle according to the type of gas.
It is therefore necessary to unscrew the screws as specified in the previous point; with a suitable spanner unscrew the
fitting and substitute the nozzle with a suitable one. With the right nozzle, the flame must lap the thermocouple.
Important!
After having carried out the conversion to another type of gas, it is necessary to update the data plate, indicating the
type of gas for which the appliance has been converted.
• The appliance contains the instructions necessary for use.
• Check the appliances for gas leaks.
