4.
LPG gas will not flow as readily if the outside temperature is very low, i.e. below
freezing. There is not much you can do about this condition until the propane
cylinder locker warms up.
5.
Ignition System Fails to Spark
1.
Check that the ignition lead is connected to the spark plug.
2.
Inspect the ignition lead from the valve to the spark plug, ensuring that the lead is not
shorting out before reaching the spark plug.
3.
Clean the spark plug electrode to ensure a strong spark is evident. Brass wool or light
grit sandpaper work well.
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.
6.
Once your heater is completely reassembled and connected, mix some liquid soap and
water and perform the standard test for leaks with your fuel system. Test in a well
ventilated area, with no open flames.
