11.6 Gas rates
The supply from the governed meter must be of adequate size
to provide a steady inlet working pressure of 20mbar (8in wg) at
the boiler.
• On completion, test the gas installation for tightness using
the pressure drop method and suitable leak detection fl uid,
purge in accordance with the above standard.
Due to the modulating operation of the boiler and the
need to check the gas inlet pressure and measure
the gas rate at maximum rate, it will be necessary to
force it to maximum.
• Activate the test mode "P.01" and set the value to 100 in
order to force the burner at P. max. See chapter "Specifi c
