Apologies in advance if this does not make sense however I am quite confused with some info I have rec'd from my oil co. Last Oct (2011) I had a new Pensotti oil boiler with a Riello burner installed in my utility room (8x12 size room) . I also had a new indirect SuperStore hotwater heater installed and my chimney re-lined with a stainless steel insert. Given the size of the utility room I had a fresh air intake installed as well - 4" duct work that runs from the outside of my house directly into the burner. I had my annual system tune up last week and I informed the tech I noticed some soot towards the back of the boiler - not a ton. After he cleaned out the boiler he informed me that I needed more air in the utility room. I was a bit confused when I rec'd this info as my oil co. did the install & I asked them if the fresh air intake was enough when they did the install. They told me based on the size of the room and the fresh air intake I would be fine. Now the tech tells me I'm short air and need to cut a hole in my wall and add a grate/vent, keep the utility door 1/2 open or change the door to a louvered door. The wife really doesn't want to cut a hole in the wall nor does she want to take out the solid pine door we currently have. (Finished basement)
I don't mind adding another fresh air intake if that will fix the problem. I looked on the Field Controls w/s and they have a fan in the can product - but I don't know if that will resolve the issue, if it's needed or if it's even feasible given I already have a fresh air intake into the burner already. I did leave the door 1/2 open since the tune up and it looks like a little soot came back. My co2 detector in the utlitly room has never gone off.
Any thoughts/comments would be greatly appreciated. I just want to ensure everything is working the way it should and I feel like each time I speak with someone I get a different answer.
