Hi I am a new member here and I want to say hello and thanks for any info you give me.
I have a miller mobile home furnace that is about 12 years old and still in great shape. I want to lean how to tune it up myself and change the oil jet. I am hoping some one can tell me how to do it or show me where I can find some step by step instructions with photos. Thank you very much for the help.
To actually tune a oil furnace.
You need a combustion tester/annalyzer.
Setting up the flame by eye ball(exspecially if you don't work on 1,000 plus oil burners a year) will usually cause smoke production of 3 to 4.
Which means what ever efficiency it had after you "tuned" it.
Is gone in a month or so.
Atleast one state has a law, that if the nozzle is changed, it must have an combustion efficiency test done.
Don't know if your in that state or not.
Combustion test kits/annalyzers start at about 500 bucks.
On average, it takes a tech close to 2 years to get good at setting up oil burners using a kit/annalyzer.
