Thank you Dan for this new site. I am amazed to find this new site, i haven.t been on the site since early December when i was trying to learn about Iron Fireman burners.I want to thank the ones who helped me it was a great help. I had a long winter and picked up a few thing on these commercial burners.Just like the residential world ,i had my hands full with draft issues. Right now i am dealing with one old smith dry base cast iron boiler with an iron fireman burner,slowly being replaced with Aerco condensing boilers (hydronic system) a honeywell controll system a two types of DDC systems getting married. I will be seeking HELP.
