5. Loosen the screw securing the red wire from the
quick disconnect fitting to the bottom left corner
of the power supply pilot relay. Detach the wire
from the relay.
6. Disconnect the quick-disconnect double white

power supply).
7. Disconnect the gas line from the elbow fitting on
the quick-disconnect fitting.
