Why does my gas Burnham boiler turn off after a few minutes?

Gas Boiler will not 
Start using only the thermostat 
Need to put match to pilot light 

When it does ignite 
It stays burning for only a few minutes 
Dirty Hot water blows out of the “ bleeder faucets “ and 
The flame goes out 

We tightened the bleeder valves 
We have three zones 
All three valve controls are 
Open 
All the water lines are open 

When the machine runs 
The pipes below the 
Valve controls are hot 
But above they are not 

We have an argo control panel 
Three green lights on top 
Three red lights  below

    Bad circulator? Where are you located?

    It sounds like multiple issues.

    ”Match under pilot.” That sounds like a bad thermalcouple.

    ”Pipes hot below, but not above.” That could be a bad circulator as Steamhead mentioned. Or it’s air bound. Or the static fill pressure is too low.

    Looks like the ball valve before the pressure reducing valve is closed. (No backflow preventer visible in the typical location either')
