i recently converted 3 boilers from oiled fired to gas fired using the ez carlins gas bruners on 2 of the boilers( both well mcclains) and a G3B burner on a utica boiler Starfire 3 model. The 2 ez carlins are running fine but i have received a question regarding gas usage on the utica. While the 2 ez carlins installs showed a 2/3rds increase in gas useage, the utica gas usage has tripled if not 4X creating a massive gas bill. Any thoughts on why or if there is some solutions. All boilers are steam boilers and were all cleaned and soot vacced.
it needs more static air pressure than the G3B can produce. That's why the original Beckett burner on these boilers is an AFG rather than an AF- the AF doesn't produce the static air pressure that the AFG can.
Swap the G3B for an EZ-Gas, with the proper air tube for that boiler, and it'll run much better.
