I built my own Gas. boiler , after alot reserch did all sizeing myself, and after 4 test runs think I got air adjust good now. I can adjust air in both chambers top and bottom of first chamber and secondary, and get a yellow to orange to purpel to hot blue flame in secondary, and it is HOT! I have a 3/8 steel rod that the tip is in second chamber [use it to slide panel] it is white hot, the 2 1/2 inch fire brick are glowing red hot, have to be 2000 degrees?
Is there a thing as to hot?
