WARNING: check that
• A (NB: the gas orifi ce diameter is shown in hundredths of a millimetre)
• the sensors are completely inserted in their sheaths.
• The electric connections are perfectly made and connected.
• All terminals and connections are correctly fi tted to their respective plugs.
• Any new gas valve setting and/or pressure adjustment (note: the G20 adjustment is done
by the manufacturer) has been carried out.
The gas supply pressure, measured at the inlet pressure take-off using a pressure gauge, and
specifi cally indicated on the valve
must have a value as shown in Table B

Important: the manufacturer declines all re-
sponsibility for heaters that have undergo-
ne a transformation as concerns the type of
gas in use.
For all types of gas, NATURAL and LIQUID, the “slow ignition” adjustment device on the gas
valve is adjusted by the manufacturer:
