SOURCE: Vulcan Ilec central heater main burners turn off after few second

Flame rollout sensors, overheat thermistor, air proving switch, bad earthing, blocked flue. Any of these things can cause your problem. If its a permanent pilot, is it clean burning?? If electronic ignition, is the flame rod clean i.e. no carbon or rust etc.. Safest bet is a qualified gasfitter take a look at it.

SOURCE: I had a vulcan central heating unit that was made

Hi Rob, The number you have listed AUW230A may be the model number. You say its a central heat so, If it is a package unit, the model, serial, and all of the ratings would be on the unit near the elect box on a package unit.I do know by the # you gave me it is a Vulcan 3000 watt thermostatically controlled Immersion heater. Here is a link I can give you, they deal with this heater for parts Ect. that maybe of help to you, it is www.grainger.com. There are many model # and I believe this is it, AUW230A. I hope this helps Rob, Sincerely,
Shastalaker7

The pilot light takes a long time to light, once lit it barely has but a small blue flame, what is the problem?


Ensure that the unit receives the standard gas pressure as rated on its nameplate.
Pilot orifice may be partially plugged or has some dirt on it, You have to dismantle the whole pilot assembly to gain access in cleaning the pilot orifice. Be careful not to enlarge the orifice bore in cleaning for that will only result to poor pilot flame quality.
The thermopile must be free of soot or soot form of dirt in order to detect the right amount of heat from the pilot flame so that it could also, in turn generate the right amount of voltage needed by the gas valve for pilot and burner operation.

Regards.

Hi, the lights on my circiut board are flashing the one on the left is on all the time and the one to the right of it flashes two times and then waits and then flashes two times again


Error Codes
A green LED indicates system faults
Steady On: System OK
Steady OFF: Board control fault or no power applied
1 Flash: Ignition failure (control in one-hour lockout)
2 Flashes: Pressure switch fault, fails open (switch is
stuck open)
3 Flashes: Limit switch open (main or auxiliary)
4 Flashes: Pressure switch fault, fails closed (switch is
stuck closed)
A yellow LED indicates flame status
Steady on: Normal flame is sensed
Flashes: As flame weakens, frequency of LED flashes
increases

hope this is helpful.

I have the same problem, heating unit will not ignite, it trips out, i go into the roof cavity and remove the top of the unit (4 screws) and there is a motherboard, it has a Green light flashing what tells you the type of fault it has, mine has 3 Flashes telling me it a combustion air pressure system failure, ithen push the reset switch and it starts to initiate, a red light comes on and then it ignites and it will work for about 30 minutes to an hour and a half.

Hope this helps
