I have a Weil Mclain CGi boiler about 8 years old. It fires up great, But after about 3-5 minutes the ignition starts again while the flame is ON. I hear the clicking of the ignition and the blue flame gives a puff of yellow/orange for a few seconds. This continues for the doration of the run. The flame is not going out, just acting up when the ignition starts up. Could this be a flame sensor issue? Could it be that the sensor is not sensing the flame and thinking it is out, thus trying to start again? The unit looks and sounds great except for this one issue.
Any help would be greatly appreciated
