First off I heat mainly with wood. I have only used 75 gallons of heating oil so far this winter. I am in CT and it has been brutally cold. The furnance is mainly used when the wood stove cant keep up or I am away on the weekend etc. Basically I dont use it much.
Bought my house last summer and It had a brand new Carrier oil fired furnace. It ran like shit so I decided to tune it up myself. I bought some basic tools like draft gauge, pump pressure tester, etc.
I tuned it up myself. It was pretty easy. I found tons of stuff wrong with it. Oversized nozzle, too high pump pressure, draft wrong etc.
I set everything at the factory settings. Pulled it apart and cleaned the heat exchanger and flue pipe spotless. I then changed the nozzle, cleaned the pump strainer, changed the filter. Draft was set to specs.
By the book I am supposed to do a smoke test and then using an combustion analyzer make adjustments to the head air setting. I set it to base factory setting and had a bit of smoke. Turned the air up a hair and its been running with just about zero smoke. I cleaned the flue pip that goes into my chimney spotless and there has been to smoke residue on it. Also, when its running looking through the barometric damper there is no visible smoke. Appears to be running extremely clean. Flame looks great based on online research. Duct temp rise is right at spec as well as flue temps.
The only thing I cant do myself is adjust the CO and 02 readings. Are these more for perfect efficiency? I am burning clean and right at specs. Since I don't use much oil if its off by a slight bit it will equate to very little since I dont use it much. I could see if you were using 900 gallons a winter where you would want absolute efficiency.
I do have a security system with co and smoke detectors. I also have battery back up detectors as well.
Any HVAC or Oil burner techs out there have any insight?
