4. Once all connections have been made, a careful check
of all fi ttings for leaks and function needs to be made. Use

Fuse Update on Main PCB in GCM 2010
NOTE
Depending on version at time of purchase
or other updates some GCM 2010 units may
not need to have the fuses updated. It will be
necessary to verify this. One way to do that is
by removing the cover and inspecting the two
fuses at F14 and F15. The following explains
how to do that and update the two fuses.
WARNINGS
Disconnect primary power at the source before
starting the procedure.
Use caution when handling the printed circuit
board as damage can result from improper
handling or from electrostatic discharge. Wear
appropriate static-handling equipment and
grounding strap while performing this replace-
ment procedure.
1. Remove the screws securing the cover panel to the gas
control module. Save the hardware for re-use.
2. Carefully remove the cover from the module noting
the attached ground wire. Remove the ground wire if
needed.
