Weil McLain Ultra experts ?

KAD

New poster. I've had an Ultra 60 for maybe 8 years. It has trouble firing up. It lights , then I hear that motor boating sound , then it goes out. After so many tries I get an error . Can't remember code right now. I reset and it usually does the same thing. If I crack open the little sight glass while it is motor boating it will stay lit and then ramp up to high flame. Why would doing this let it light? I have cleaned it in the past and seemed to help. I've had this issue for years. Any ideas? Thanks

May have condensate built up in the combustion and exhaust lines...

You need a full tear down and cleaning. The condensate is backing up like John said.

and a combustion test.....

Thanks for the comments. I did a full cleaning today. A lot of crude in the bottom and wet looking from the bottom halfway up. This is a propane burner. Thanks again.

Has that hopefully resolved the problem?--NBC

Did you use the service kit? Did you run a combustion test?

Make sure to get the cleaning kit it comes with gaskets. If I were you I would leave it to a pro. Just make sure that you let them know which unit you have when you call so they get the proper kit from Weil McLain.

Water in the flue collector? I know where this is headed......
