: I have a large cast iron sectional boiler (650,000)
: Whatever the temperature is outside the boiler runs for 2 min. and is off for 2 min. This can not be how it was desigend to operate.
+++ No, it wasn't designed to operate that way. Steam boilers were invented to use a steady fire over a whole hour all day, with the fire varied with more or less wood. The burner fire should imitate that. Your observation points to having too large a burner input.
The boiler cuts in at two pounds and off at four pounds. I was told that 5# is to high of a pressure to run at? Thank for any help.
+++ 5 lbs is too high for a residential boiler. 2 lbs is sufficient. Vents are often damaged at over 3 psig.
