16. Replace burner. Slide the burner in at an angle
with left side lower than the right side. slide the left
side onto the injectors, making sure the burner leg
remains at a 90° angle to the base. Lower the right
hand side down in to place. Make sure the burner is
as far left as possible and the injector shoulders are
inside the burner.
NOTE: It is very critical to keep the left burner leg,
which holds the injectors, at a 90° angle to the base.
(Fig. 58) This keeps the orifices aligned with the
tubes inside the burner. Failure to do so could affect
the flame appearance and performance of the unit.
