Gas Governor Setting
If the gas supply pressure is over 3.3kPa (330mmH2O) or in the case of severe gas pressure fluctuations, a gas governor is installed to supply
the gas with a constant pressure to the burner. In this case, it is necessary to correctly adjust the gas pressure suitable for the gas usage..
