FUEL LIMIT SETTINGS
Fuel Valve Max Position – This is the maximum position the fuel valve will ever be
allowed to reach.
Fuel Valve at Ignition – This is the valve position used when attempting to ignite.
Typically, it takes more fuel to establish a flame than to maintain it after ignition.
Default setting is 15%.
Min Fuel Valve During Run
–
Some gas must flow through the main butterfly valve even
at low fire to maintain a flame. This minimum gas valve position is set here. A setting of
10% is normal for most applications.
Automatic Low Fire Enable/Disable – Automatic Low Fire adjusts the low fire position
based on the airflow through the burner. Higher airflow requires a higher minimum
valve position to maintain the flame, while in lower airflow the flame can be maintained
with less fuel. Disabled by default.
