RECOMMENDATIONS FOR GAS CONNECTION
Essential recommendations for safety
•
The gas connection must comply with all applicable local standards and regulations,
and the circuit will be equipped with a gas pressure regulator as required.
•
Do not check for gas leaks with an open flame. Use a gas detection device or
bubble test.
•
The gas burners are factory preset for use with natural gas [equivalent to G20].
Do not adjust or attempt to measure gas valve outlet pressure. The gas valve is
factory-set for the correct outlet pressure and requires no field adjustment.
•
The natural gas to propane conversion or the reverse is not authorized in certain
countries such as Belgium. Refer to the table of gas categories in the technical
characteristics of this manual.
•
The gas orifice installed on the boiler must never be modified or replaced with a
different size orifice, except in the case of a gas conversion process, which shall be
performed according to the provided procedure and requirements.
•
The CO
2
, gas flow rate, air flow rate and air/gas supply parameters are factory-
preset and may not be modified
in Belgium
, except for type I 2E(R)B boilers.
•
Do not change the OFFSET (A) setting of the gas valve: it is factory-preset and sealed.
Essential recommendations for the correct operation of the appliance
•
Refer to the technical characteristics of this manual or to the burner
documentation to know the connection diameters.
•
Bleed the gas duct and check thoroughly if all the boiler tubes, both internal and
external, are tight.
•
Check that the gas type and pressure from the distribution network are compatible
with the appliance settings. Refer to the product type plate.
•
Check the boiler electrical connection, the boiler room air vent system, the
tightness of flue gas outlet pipes and of the burner chamber plate.
•
Control the gas pressure and consumption at appliance start up.
•
Check the boiler CO

adjustment (refer to the adjustment procedure and the
technical data).
