Need some information regarding my 2 year old V-8 series Burnham oil fired Riello burner. Last tune-up 9 months ago.
Is it normal for the burner to turn on for 20 seconds, then shut down for a few seconds, accompanied by noise-the sound of rushing air or hissing , followed by the burner turning on for 20 seconds. This might occur for 10 cycles before the burner shuts down. Thanks in advance.
