Gas boiler burner flame too big/yellow
We have an American Standard gas boiler thats been a reliable heater, but I think the flame is set too high now. The air shutter adjustment doesn't make much of a difference, I think there is too much gas being sent to the burner. How can I turn it down so the flame is the normal blue with just a tiny bit of yellow? The control is a Robertshaw control, it looks like the Millivolt models on their web site.
