NG position when arrow is close to blue screw. It will
not “snap” at LP (Red) position. (Fig. 61)
19. Insure manifold pressure remains between 3.2”
- 3.5” w.c. for NG and 9,5” - 10” w.c. for LP. To adjust
the manifold pressure, for NG, using a torque #10
key turn the blue screw clockwise to increase the
manifold pressure. Turn the screw counterclockwise

21. 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. 62) This keeps the orifices aligned with the
tubes inside burner. Failure to do so could affect the
flame appearance and performance of the unit.
