Hi! I hope someone can help. We had a draft inducer (old chimney with a few turns) and fresh air kit installed in Dec. on recommendation by our oil company tech because of nozzle problems, sooting up. Chimney was cleaned in Sept. and is clear. Now, the techs have been out every 2 weeks because the burner pulsates and runs rough. They've replaced the oil pump, adj. the pressure and changed the nozzle size (per the sticker on the side of the boiler), The last tech put a coffee can(!) under the burner to help keep it tipped into the boiler because it was leaking onto our floor underneath. The efficiency has gone done considerably (they leave the printout of the stack test). Last tech was out here last Wed. & ran fine for a day then started running rough & noisy. Im a stay at home mom, so I hear it all day long. Scares me. The oil co. tech is coming out tomorrow afternoon again. I like our oil co., but this can't be profitable for them. (We have a contract).
Also, the last tech said the draft inducers safety switch isn't wired into the burner to shut down in event it doesn't run. Is this a problem? I don't want to die of CO poisoning, but he said it wouldn't affect the draft that much. Can anyone shed light on this problem? Thanks!
