To terminate calibration without memorising the set values either:
a) set the function selector to (OFF-unblock)
b) turn off the power supply.
Calibration is completed automatically, without memorising the
minimum or maximum values, 15 minutes after activation.
The function is also terminated automatically in the event
of a shutdown or permanent block. Again, values are NOT
memorised.
NOTE: to calibrate only the maximum heating value, remove jumper
JP2 (to memorise the maximum value) and then exit the function
without memorising the minimum value by setting the function selector
to OFF or by turning the boiler off at the mains.
After any intervention on the gas valve adjustment component,
seal with sealing paint.
4.9 Converting from one gas type to another
The boiler is supplied to operate with natural gas according to the
specifications on the technical data plate.
However, it may be converted from one type of gas to another by using
the special kits available on request.
- Natural gas conversion kit
- LPG conversion kit.
This conversion procedure must only be carried out by the
Technical Assistance Service or by personnel authorised, also
once the boiler has been installed.
For information on assembly, please refer to the instructions
supplied with the kit.
After converting the boiler, it must be adjusted again. Follow
the instructions in the relevant paragraph and apply the new
identification data plate supplied in the kit.
