Content

When the gas boiler is normal at a low fire and switches to a high fire, it goes out or flickers unsteadily.
Reason:
1. The air volume of the damper of the high fire is set too large.
2. The micro switch of the oil valve for high fire (the outermost group of the damper) is not set properly (set to a larger air volume than the damper for high fire).
3. The oil viscosity is too high and it is not easy to atomize (heavy oil).
