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. 56)
This keeps the orifices aligned with the tubes inside
burner. Failure to do so could affect the flame appear-
ance and performance of the unit.
