Gas burner systems and methods for calibrating gas burner systems

A gas burner system comprising:

• a gas burner through which an air-gas mixture is conducted;
• a variable-speed forced-air device that forces air through the gas burner;
• a control valve that controls a supply of gas for mixture with the air to thereby form the air-gas mixture;
• an electrode configured to ignite the air-gas mixture and produce a flame, wherein the electrode is further configured to measure an actual flame strength of the flame;
• and
• a controller and an input device for inputting a calibration command to the controller, wherein upon receipt of the calibration command, the controller is configured to automatically calibrate and save a target flame strength setpoint, and thereafter automatically regulate a speed of the variable-speed forced-air device to cause the actual flame strength to achieve the target flame strength setpoint;
• wherein the controller is configured to calibrate the target flame strength set point by first determining a peak flame strength for the gas burner system and then calculating the target flame strength set point based on the peak flame strength.
