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')
