    Proper setting for pressure controls

    I currently have a 245,000 BTU Burnham gas steam boiler. I have 2 pressure controllers. One is L404F1367. The other is L4079B1033(high limit). I would like to find out the correct psi settings on each of these controllers so the boiler runs properly. Currently the settings are as follows: L404F1367- main 3.5 psi, diff 1.5 psi L4079B1033- main 9 psi Thanks.

    It depends on the system requirements and how much steam you need to fill the system. In general terms, without a system description of the sytem, your setting sound high. Some very big systems run on very little steam pressure. I generally use .5 cut in with a differencial of 1 for a 1.5 cut out. High limit should not be set higher than the rating of your vents or you will be changing them often. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"
