Hi, First post thanks in advance for any suggestions!
I have a Rudd Multi-Tube boiler ser 480-01974 model CB576C for 6 small apartments and 2 commercial units. Guessing it is 1974 or earlier model.(maybe 60's, building is 100 yrs plus)
Pump--->Flow Switch--->Boiler--->Air Tank/auto fill--->Pressure/Temp--->Level Control---Honeywell Control.
max input btu 576000
pump in return 2" Armstrong 1/6th HP Pump Motor P/N 817025-005
Boiler piping 2" to 3" to 1.5"
Limit control set at 175 degrees
Pressure is 16PSI
The problem is that the boiler is on for <5 min and temp gauge says 140 degrees when it stops
Temp Gauge reaches 120 Degrees after 12 mins and the cycle starts again.
Pump only operates when there is a call for heat.
Outside temp today is 3 degrees Celsius = 37.4 degrees Fahrenheit
Basement has no rads but it sure is a sweat shop, all units very warm too. The thermostat is on the second floor hallway.
