I disabled my main gas valve to move my dryer hookup and upon reconnecting it I am unable to get my boiler to go. Pressure sits around 15psi, gas is definitely on (tried bleeding via a screw on the valve), and electricity is on (when switch is flipped the transformer flips). I've made sure the thermostat is talking to the system and when it kicks on and the boiler mostly acts like it's working (vent opens, boiler clicks) but no flame is present. I've tried both the on and pilot settings on the valve to no avail. My setup: New Yorker CG-D natural gas boiler Honeywell VR8200 valve Honeywell L 4080 B 1436 aquastat Any ideas? What other info can I provide? Thanks in advance.

My basement and 3rd floor heating stop deliver heat. I first try to bleed those pipes, no water come out. I thought this mean there is a airlock and move on to purge pipes using street pressure by bypassing feeder. Water and bubbles start to come out between 25-30 psi. However, I let the water run for more than 10 gal, and bubbles are still come out and problem cannot be solved. Any clue?
