Losing prime on oil boiler

Bruce McCaffrey Jr.

I would like to send out a thank you to those helped my problem. I have vacuumed check the lines and I conclude that the line is kinked. So I installed a new tigerloop and it seems to be taking the slack.

Thank you for the help

Oil Boiler losing Prime.

I have a small commercial application with a New Yorker boiler using a Beckett oil burner. About a week ago my company received the call of no heat. At first arrival the problem seemed to be simple and the nozzle and oil filter were changed. The burner ran under normal operation for about a day, with that a weak spark was indicated and an electronic-ignitor was installed. The operation ran for about another day and at this time the pump was changed due to an indication of low oil flow, and at the same time the oil line was blown out. Now this burner was a two pipe system which a tiger loop was installed in its place by a previous contractor. I am still experiencing a loss of oil flow to the burner after about 30 to 60 minuted of burn time. In addition I was notified by the building owner that the maintainance workers have been pushing the reset button and the oil lines leading to the in ground tank where asphalted in some places recently. I feel as if the line is sucking air and if anyone could help please reply.

Thank You,

What happens....

if you put a hand pump on the supply line? Are you pulling up air or oil? Also, how about some vacuum reading on that supply line.What are those numbers? Can you isolate the line into sections and vacuum test to try to narrow down where the air leak may be? Bad fittings? Pinholes? compression fittings? Is the tank above the burner even though its underground? Or is the level of oil below the burner? Can you switch to the now abandoned return line and see what happens? Maybe the return can fuction as the supply temporarily provided its immersed sufficiently in oil. The tiger loop is a clear indication that you have inherited someone elses problem. Find the air leak. You may have to dig if the pavers broke the fuel line. Get some vacuum readings first.

install a suntec

filter with o.s.v. and vacuum gage ahead of the tigerloop...
if you have problems abandon that line as any vacuum leak you cannot see is an EPA violation waiting to happen.

I hope you replaced the kinked oil line? That would be the only cure for your problem, all others would be a band aid.
