● gas supply pressure
● secondary pressure
● the volume of gas to be fired
● type of gas
If the gas inlet pressure is higher than the Pmax. value given in burner’s technical
data or PI diagram, reduce the gas inlet pressure in the regulating assembly. If the
pressure regulator is not equipped with a safety relief valve and safety shut-off valve,
install these valves according to the instructions given by the manufacturer. Also any
impulse tubes must be installed according to the instructions given by the regulator
manufacturer.
If the gas inlet pressure is not stable, stabilize the pressure with the
pressure regulator.
