90% of the time, this problem is caused by either a clogged gas orifice on the pilot light's gas line, or by dust/debris in the pilot air intake, as stated by tradesman1. Start by blowing compressed air through the pilot air intake, both directions. If that doesn't solve the problem, remove the pilot assembly, then the pilot orifice, and blow compressed air backwards through the small orifice. The bottom line is that anything that causes the pilot flame to reduce in size will trigger the oxygen depletion system and that will result in the unit shutting itself off. This is a safety measure. Other possible causes: insufficient gas pressure to the unit, high altitude, defective thermocouple.

Does the pilot light stay lit if you continually depress the control valve?
If the pilot light stays lit as long as you keep the valve depressed, then the problem is the thermocouple is bad. The pilot light makes enough electricity via the thermocouple to hold open the gas valve that feeds the burners. If the thermocouple fails to produce that electricity, the gas valve will shut down and switch off the gas flow to the whole unit.

Have a 20yr + old vulcan gas heater and I cannot turn pilot off


Hi, If you are talking about the knob on a gas valve that you use to light the pilot and turn it off also, you have to turn the knob either ccw or cw to turn it off. To light the pilot is when you turn the knob to pilot and push down and hold it, light the pilot while you continue to push it down for a minute, and then slowly release it and pilot will stay lite. So, if this is the type you have just turn knob one way or the other and it will shut off. If you do not have this type set up, just turn off the gas to the furnace at the flex line as there should be a hand valve by code and by law that supplys gas to you're furnace. You can shut it off there and the pilot will also shut off.
Sincerely,
Shastalaker7
PS If you don't have either one of these shut off's, on the main gas valve it self, you should have a place marked pilot adjustment. Pop the small chrome cap and insert a very small screw driver to turn it cw to shut off pilot.This would be you're last choice.

How do you shut down


the pilot light always stays on, its designed to allow your heater to turn on by itself without you needing to light a match every time. if the pilot light is burning you have nothing to worry about. its when the pilot light goes out that a small amount of gas leaks into the room. and by small i mean smaller than a hand held lighter... if you still want to shut the entire thing down you could turn off the gas line feeding the heater or possibly the whole house, otherwise the pilot light will stay on. as far as the actual heater turning off, thats probably controlled by some sort of thermostat somewhere. if you set the temp to very cold it should stay off. if that doesn't work then you may need a new thermostat.

Pilot light lights but when turnd on it does not get hot and shuts off in 1or2 minuts


This is normally caused by the thermocouple. This is the part the pilot light heats up to let the heater know the gas is on and the pilot light is lit. The heater will shut off if it thinks the pilot light is not lit for safety reasons. You will need to change the thermocouple for it to work again correctly.

Gas log will not stay lit for more than 5 minutes


Sounds like the gas regulator has failed.

There will be sufficient gas flow to light the pilot and get a flame prove, then the main burner lights, you will probably see the pilot flame reduce somewhat, and no longer fully surround the flame prove sensor.

When the unit is relighted, the complete sequence starts all over again.

Have the gas regulator checked and adjusted (if adjustable) or replaced by a qualified technician.
