Gas saver valve and method using the same

A method for regulating flow of a gaseous fluid, comprising the steps of:

• placing a gas saver valve in communication with a supply of a gaseous fluid and a heat generating device, the gas saver valve including a regulator to adjust a gas pressure of the gaseous fluid and a control member calibrated with a plurality of marked settings each corresponding to a value of the gas pressure;
• selecting a gas pressure to flow through the regulator by adjusting the control member to a calibrated marked setting of one or more of the marked settings in a range of gas pressure less than a reference gas pressure in operating the heat generating device, the reference gas pressure and the range of gas pressure generating a temperature in an operational range of the heat generating device;
• indicating by an indicator the selected calibrated value of the gas pressure to flow through the regulator corresponding to the selected marked setting of the control member;
• and
• adjusting the gas pressure of the gaseous fluid by the regulator to the selected calibrated value as indicated by the indicator in the range of gas pressure less than the reference gas pressure in operating the heat generating device.
