Gas, Steam, Intermittent ignition operates erratically...
Steam Boiler - Dunkirk Radiator Corp. M-PS52, S-52820093, 124,000.Btu/hr
Intermittent Pilot Module S86G
Honeywell gas valve M?
McDonnell-Miller water level SO812

Boiler does not cycle overnight 7:00am Tstat reads 58F calling for 62F. It seems to be in Lockout and when Reset starts the cycle. Sometimes the gas valve "clicks" on and lights in 5 seconds, sometimes as long as 90 and sometimes not at all.
I suspect the gas valve.
