Recently I been experiencing a weird problem with my oil burner. Whenever the oil tank has approximately 1/4 left, the oil line will get air inside the line between heat cycles. I will have to bleed the air out in order for it to fire. Once the thermostat is satisfied, the boiler shuts off and the next time the thermostat calls for heat, I have to go and bleed again.
This does not happen when I have more oil in the tank. What could be the problem?
