I own a 2 family house with basement. Replaced old gas steam boiler with Burnham Independence KIN8S (245000 BTU INPUT) 644SQ. FT Steam. The boiler is cycling approximately every 30 sec0nds ON/OFF from pressuretrol settings.My pressuretrol(L404F)Main setting position indicator set @ below 2.0PSI @ Diff. position set below 0.5PSI. Verified CUT OUT & CUT IN pressure using pressure gauge on boiler (0-5PSI range). Cut out pressure measured 2.4PSI & Cut In pressure measured 1.5PSI. This calculated a subtractive differential of 0.9PSI. My question:
Is my boiler is OVERSIZED for my house causing cycling? Does Burnham sell conversion Kits to reduce boiler output? Is my pressuretrol working correctly? I cannot adjust the CUT OUT pressure less than 2.4PSI. Is the pressuretrol the correct model for my boiler?
Any help is greatly appreciated
