Burner Does not Stay Lit

1. Check to make sure the pilot is still on. If it has been accidentally extinguished,

voltage will no longer be generated, and the valve will have snapped back to the

closed position by the stainless steel spring.

2. There could be a problem with the thermocouple. The small bulb-like attachment

protruding into the pilot flame is one end of the thermocouple.

3. Check first that the thermocouple is screwed into the valve tightly enough. A loose

connection will not transfer the 1.5 millivolt. If it has been tightened too much, the

insulating washer will have been crushed, shorting out the thermocouple, and so will

not generate the 1.5 millivolt. It must, therefore, be replaced.

4. Heaters are tested at the factory and thermocouple failure problems should be very,

very rare. If necessary, however, remove the valve end of the thermocouple from the

valve as described on the following page. Lightly sand the end which has been

removed from the valve with very fine sandpaper. Replace in the valve and test. If

this does not work, the thermocouple must have failed and will have to be replaced

5. The electromagnet (solenoid) inside the valve may have failed and will have to be

replaced.

General Information

1. Thermocouples are made out of two dissimilar metals. One end of each metal is

fastened together. When this connection is heated up, a small amount of electricity is

created (1.5 millivolt) and can be measured between the other two ends of these wires.

2. The outside of the thermocouple is a copper tube, which acts as a conductor and the

inside is an insulated nickel wire, which at the other end, is separated from the copper

wire by a very small insulating washer. This end of the thermocouple screws into the gas

valve, which contains an electromagnet(solenoid).
