rack support allowing the burner rack assembly to swing down
(See FIGURE 4).

assembly up and out of the manifold support brackets. The
burner rack assembly should now be completely removed

You may have to remove a factory-installed air baffle from the
burner rack. Visually inspect the burner rack to determine if it is
equipped with either of the air baffles illustrated in FIGURE 5.
Not all heaters are equipped with an air baffle. If your burner
rack is factory-equipped with an air baffle, remove and discard
the air baffle. FIGURE 5 indicates which screws to remove.
