4. Depending on the version of the controller, the minimum flame height of the main burner can be
set at the factory by the manufacturer or can be adjusted by the installer.
If, despite the adjustment, the desired pressure was not achieved, check the pressure of the gas sup-
plied using a gauge connected to the measurement point of the input pressure. If the inlet pressure is
within the normal range, replace the controller; otherwise take the necessary steps to ensure proper
gas pressure.
