Blue Johson Control as you asked. Everything appears to be in order. Nat Gas for oriface...

was pilot 8" long before new gas valve? sounds like pilot way out of adjusment or pilot orfice missing. get rid of
P O S johnson blue box install 53L90 kit.
Was thinking of that, I know there have been a few updates since the install... heh, heh. Yes, the pilot did that when I went to adjust it from the original valve, I concluded the valve was bad... when I installed the new valve pilot did same thing and pilot adjustment doesn't make a diff. Going to test the incoming pressure as it still has that damn 1/2 psi regulator just before the gas valve. Wondering if that regulator isn't throwing things off... I know it can be eliminated.
kc you changed the gas valve cleaned pilot the orfice is the right one and you have to lite the pilot by hand
the middle tube of hx is yellow flame and the pilot is still 8ins and yellow to.you pulled the blower and hx is good the inducer is working correctly. something is wrong with this picture. know if one tube is burning yelow with the blower off the tube is clodged or burner is clodged one or the other if the tube were you would have roll out and safety would trip.gas pressure does not sound like a problem cause the burners lite and work properly from what you have said. two gas valves doing the same thing not to common and the pilot burner you cleaned twice and made sure the orfice is correct. the sparker wont lite the pilot but a lighter will. ok now lets stop over thinking this and go back to the begining first thing is change the pilot burner it is defective if this is rely happening.
i have been a service teck for lonox since 82 and have never come across this on a g23. if nthe flame on the pilot is yelow and 8 inches long i cant see the flame get the proper flame recifacation to being on the burners and you sould have a biuld up of soot on the heat exchanger.
change the pilot burner with the correct one from lenox for the g23 and you should be fine
He's probably got the thing going now.
8" pilot flame would be rather large. Exaggeration? But still too big.
I jumper R + W, again the pilot won't light
I wonder what the voltage was at the gas valve? And also what the incoming gas pressure is? 2 things that should be checked with the symptoms he mentioned.
"Blue Johson Control as you asked"
Used to be if you saw them on a no heat= test them
Then it became= suspect them, they are intermittant
and then= Change them whenever you see them, working or not. About a hundred now or a hundred and emerg call later.
check the pilot orfice size. 8" pilot flame is too high. can you adjust pilot flame? also checked around inducer housing make sure it is sealed and not pulling pilot flame. I have experiece it where leakage around inducer will prevent pilot lighting.
