Step 14
A. With the control valve and pilot assembly out, on the back of the control valve there is a nut with wire on it. Using a #8mm open end
wrench, remove this nut and the pilot assembly will be free from the control valve.
B. You now will need to remove the tip switch from the tip switch bracket. There are two small screws and nuts. Remove these and your
pilot will be free.
Note: When installing a new pilot, you need to make sure the tip switch is mounted to the tip switch bracket. While reconnecting the nut
with wire to the back of the control valve, tighten it only finger tight plus a 1/4 turn. If you do not have to replace the control valve, follow
the instructions in reverse and reassemble the control valve and pilot assembly to the heater.
Note: when reconnecting the pilot to the pilot supply tube and the burner supply tube to the control valve, do not over tighten.
CAUTION: it is possible to crack the nut.
C. Once assembled, a leak check on these connectiosn and the regulator hose assembly must be performed.
