Looked at a job today. Had an oil fired boiler I have never seen before. Circle Combustion.... no paperwork of course.

It had a riello burner, two piped, Three pass boiler. Certification was was from Calortencia... Europe. Had not been cleaned in awhile. LONG run to a  power venter. 25'... yuck!

Google has only an address in Jersey.

    yes your right

    They were a Pensotti boiler , instead of the Mario guy on the unit it came with a swirly emblem .... Mid 80's boiler , the cat's meow in it's day ... Then they went out of business

    Yes keep it cleaned....
    I have enough experience to know , that I dont know it all
