c. Plug the pipes with the insulation material.
d. Secure the oven heater baffle to the oven wall with the four Torx screws in the tabs.
The tab adjustment screws should be loose. Carefully center the oven heater baffle
inside of the oven. Be sure that the center hole in the oven heater baffle screen is
centered over the blower motor shaft. The tolerance is very small. The oven heater
baffle will not move left or right, nor up or down more than a couple of millimeters.
However, be sure that it is centered in the oven over the blower wheel. This will
ensure that whenever the GC is turned on, the blower wheel will not be touching the
heater element mounted to the oven heater baffle.
