the valve and holds the valve open. If the flame is accidentally extinguished, the
thermocouple cools, causing the electromagnet to spring back and closes the valve,
therefore, no flow of gas.
4. If the thermocouple is not holding the valve open, check first that it is screwed into the
valve tightly enough, as a loose connection will not transfer the 1.5 millivolt. If it has
been tightened too much, the insulating washer will be crushed, shorting out the
thermocouple, and so it will not generate the 1.5 millivolt, and must therefore be
replaced.
Replacement Instructions
1. Turn off the gas supply. Remove the main gas supply line to the heater. using 2
wrenches (5/8" & 3/4", or 16mm & 19mm). Take the heater off the bulkhead.
2. Loosen the 1/2" (13mm) compression nut on the valve which connects the copper line
leading to the pilot flame assembly. Remove line from valve.
3. Remove the 2 phillips screws on the outside of the heater which hold the pilot
assembly.
4. Now carefully pull out the pilot flame assembly so that you can undo the screws
which hold the thermocouple in place. Remove the other end of the thermocouple
from the valve (5/16", 8mm, crescent wrench), and you have the thermocouple out.
5. Replace the thermocouple, reversing the above procedure, but being extremely careful
when you first put the end of the thermocouple into the valve. If you tighten too
much, you will crush the insulating washer and need another new thermocouple.
Finger tight plus a 1/4 turn with a wrench is enough.
compression fitting on the pilot fuel line, tighten firmly with the wrench. Be careful
not to over-tighten.
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.
To Replace the Electromagnet (Solenoid)
When you remove the thermocouple from the control valve, remove the larger nut with a
9/16" (14mm) wrench. The electromagnet should fall out - if not, push the valve stem
where the knob should be and it will come out easily. Install the new electromagnet, with
the spring end first. Replace the nut, and re-install the thermocouple back into the control
valve.
