7.3 Nozzle replacement
Changing over to a different gas type
Only authorised specialists are permitted to
change over to a different gas type.
The nozzles needed for the gas type to be set
are available as a conversion kit. Please specify the
appliance type and the required gas type.
Nozzles can be replaced without having to open
the housing.
Loads for all gases
For all gas types and pressures, the rated load
is achieved by installing the high and low setting
nozzles for the required gas type (see nozzle
table).
The low setting nozzle is screwed in fully at the
works, and so the lowest quantity is set.
Replacing the low-setting nozzle 1
Proceed as follows:
– Disconnect the appliance from the power
supply!
– Remove the cover from the underside of the
appliance under the gas valves.
The low-setting nozzle 1 is located in the gas
valve and is screwed in from below. (see Fig. 8)
– Unscrew the nozzle and insert the new nozzle as
specified in the low-setting nozzle table. The
nozzle must be screwed in fully. Fit the cover
cap again.
If it should be necessary to correct the low-setting
nozzle 1 as the result of deviating gas types and
pressure, the flow rate can be increased by turning
to the left.
