When the gas control cancels the fault message, the alarm is also cancelled. If the reset fails, the
alarm will activate again. This may be due to one of the following problems:
•
No gas supply: check that the manual gas shutoff valve is open
•
Insufficient gas pressure or incorrect gas type: Refer to Section 3.4 on page 9
•
Faulty ignition spark plug: replace
To cancel the alarm without igniting the heater, switch off the machine by pressing the STOP
button.

If the temperature sensor is faulty, or is not connected, or if it detects a temperature above 210
◦

Programming Parameters
Some parameters, which normally need not be modified by the user, can be programmed by a
special procedure:
1. Temperature measurement unit (
◦
C or
◦
F)
2. Maximum preset temperature (Tmax)
3. Operating temperature (TF)
4. Temperature regulation hysteresis (H)
5. Temperature for automatic shut-down (TA)
6. Heating type (Electric, Gas, or Steam)
7. Number of resistor groups installed (1 or 2)
To enter the parameter setting mode, simultaneously press the STOP and START buttons and
power the machine on.
