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 of delivery:
■
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 replace ignition nozzle
■
Carefully insert the calibrated
diaphragm between gas valve
and Venturi tube
■
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
If the burner is in operation and
working at high output, check:
1) that the pressure at the input
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.

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.
ATTENTION
We reserve the right to modify the dimensions and constructional design as part of the ongoing technical development process.
Adjustment and maintenance
work may only be conducted
by authorised service
technicians.
