Reassemble the shutter to allow the rear injector air
inlet to close from a minimum 1/2" opening to fully

to find the correct air shutter opening for best results
depending on your altitude.

9. Refasten the two nuts and assemble the burner into
the unit by sliding the burner in at an angle with the
left side lower than the right side. Slide the left side
onto the injectors. Lower the right hand side down
into place. Make sure the burner is as far left as pos-
sible 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. 41) This keeps the orifices aligned with tubes
on the inside of the burner. Failure to do so could
affect the flame appearance and performance of the
unit.
