Weil Mclean Boiler and Becket Burner problems

I had my boiler replaced last year with a Weil Mclean Gold series oil fired boiler. I had it serviced for the first time this year. It has been nothing but trouble since it was serviced. It makes a big bang when it fires up and then after it runs a few seconds it missfires; that is it stops firing then starts again, Sort of like the fire goes out for a secnd or two. The pump runs while this is happening. Anyone know what's going on? I'm having the guy come back, but I'm a bit dissapointed in this system. It's new and should be such a pain.

oil? that was your first mistake , i hear its going to go over 4 dollars a gallon this winter , especially in new england , propane , must cleaner and easier to service ,
sounds like your "servicing" technician , got something wrong i could tell you what to look for , but since you have to ask what is wrong you probably shouldnt be dicking with it , huge fire danger or soot problem , you could potentially makes things much worse
id look for another competent oil tech ,

Oil wasn't a mistake, it was what I have always had. The town won't put a natural gas line. I don't know about Propane; seems like it could be a hassle if it becomes unavailable. As far as the oil prices, I can afford them. I'm more concerned about the misfiring oil burner etc. Maybe I got a bad batch of oil? Also, although the burner seems to have problems, I don't see any soot forming anywhere. This system runs extremely clean. Anyway, the tech is going to come back and take alook at it.

I doubt the problem is the equipment as much as the service tech. There are many things he could have done wrong so get him back to correct it.

Is the guy servicing your equipment from the original installing dealer? Don't be so quick to blame the equipment, it can't help it if it gets serviced by a nimrod.

The servicing guy is the original installer. He had to come back twice this year to try differerent nozzle types because the burner ran lousey. My old sytem was a junky old coal converted boiler with a Beckett Burner. I never once had a problem with that Becket. Now I have a new sytem with a Beckett and it sounds like a rocket engine when it starts up.
I also noticed another interesting thing. When I turn up the thermostat, the burner fires up right away. If I let it run a few seconds (about 30 seconds) and I turn the thermotstat down the burner shuts down immediately. My old system never did that. On my old system, if I turned the thermostat down, it would run a while before it shut down. Is this normal?

The thermostat tells the circulator pump to go on. The circulating water goes below the low temperature setting of the internal aquastat and that tells the burner to go on. Generally, if the turn you thermostat down, the circulator will stop running, but the burner will continue running and heating the water until the aquastat reaches the upper limit. The burner will shut down when the reservoir of water in the boiler is at proper temperature. If you have a new high efficiency boiler, there may be some new circuitry involved that would shut the burner down rather than keep the reservoir hot all the time. .
You need a new installer in any case if he has not figured it out by now. .
