First of all, I'm assuming that your heater has a pilot and not self ignition.You will need a jumper wire ( 16" of wire with an alligator clip on each end)attach one end to the terminal on the gas valve that the red wire from the pilot generator is connected to ( pilot gen. is the thing the pilot flame touches).
Now attach the other end of the jumper to the terminal where the wire from the connects to the knob where you set the water temp).
NOTE:
JUMPING BYPASSES ALL BUILT IN SAFETY DEVICES AND IS FOR TEST LEAVE THE JUMPER CONNECTED TO RUN THE HEATER FOR HEATING PURPOSES!!!!
