The on-site conversion of the gas type may only
be carried out by authorised, qualified technicians.
Prior to the conversion, the country-specific
requirements must be fulfilled.
The kit for conversion from natural gas to liquid gas
is described in the following.
Kit scope:
■
Calibrated diaphragm
■
Ignition flame nozzle
■
Notice sticker "Unit converted to..."
After completion of settings, replace notice
sticker "Unit set to ..." with the supplied sticker
"Unit converted to ...".
Proceed as follows for the conversion:
■
Disconnect power supply of the unit at all poles
■
Carefully insert the calibrated diaphragm between
gas valve and Venturi tube
■
Carefully replace ignition nozzle
If the burner is in operation and working at high
output, check:
1) that the pressure at the inlet to the gas valve
corresponds to the prescribed value for
the respective gas type.
2) that the CO
2
content corresponds to the prescribed
values for the gas type.
If the measured value deviates, it must be adjusted
with the CO
2
regulating screw.
If it is screwed in, the CO
2
value is reduced.
If it is unscrewed, the CO
2
value is increased.
Check the leakage integrity of the gas circuit again.
We reserve the right to modify the dimensions and design as part of the ongoing technical development process.

NOTE
Adjustment and maintenance work may only be
carried out by authorised and qualified technicians.
CAUTION
The fan-assisted heater supplied for operation
with liquid gas is adjusted for the gas G31.
When operating with G30 the CO
2
must
be checked and possibly adjusted.
■
Re-connect the power supply of the unit and
prepare the unit to start
■
Make sure during the ignition process that no gas
emerges at the copper pipe connection to the nozzle
