no heat in one zone- all baseboards
I have a burnham seriese 2 model 204NCL LEI223 CGA 4.9.1969 boiler.
Problems: No heat out of one zone- all baseboards cold
Checked thermostats- all work and valves make noise when turned up, switches in each zone make contact.
Took head of and verified that valve body turns loosely.
Gauge reads 192 degreess and at 18 psi
Question: when thermostat calls for heat and switch makes contact, how long does furnace remain on. When calling for heat it
only stayed on for a few minutes- 5 minutes. Is this normal?
Question: recirculation pump- comes on approximately every two - three minutes and stays on for 8 seconds, cycles through again
Is this normal?
4 zone system
one upstairs- 3 bedrooms
one upstairs- living room and dining room
one downstairs- west
one downstairs- east
all eat baseboards cold ( checked with infrared )
Question: if all thermostats are on shouldn't the furnace burners be on for quite a while until all pipes heat up?
Question: If i close all thermostats, and turn one one, how soon will it call for heat ( i.e. ) should the burners fire up
and stay on until temperature is reached.
Main Problem: east downstairs, pipe is cold above zone valve, all baseboards are cold?
I have included a diagram, if i need to shut down boiler in order to get water into it or reset system could you show me using hte diagram how i would do that
