For Combination Gas/Oil Burners–Initial Adjustment (see
Figure 3.2):
1. Adjust the oil gun position by loosening gland "A".
2. Align the conical faces of the oil and gas guns.
3. Once both guns are aligned, tighten gland "A" on the oil gun.
Note:
After this initial adjustment, all subsequent adjustments for
combination gas/oil burners require that both guns be moved as
a single unit.
For Combination Gas/Oil Burners–Subsequent Adjustments
(see Figure 3.2):
1. Adjust the entire gas/oil gun assembly by loosening gland "B".
2. Move the entire gun assembly until the oil nose cone aligns with
the small diameter of the throat cone.
3. Once both cones are aligned and the gas gun is centered in
relation to the throat cone, tighten gland "B".
For Oil Only Burners (see Figure 3.2):
1. Adjust the oil gun position so that the end of the oil nose cone
aligns with the small diameter of the throat cone as shown at left.
2. Verify that the oil gun is centered in relation to the throat cone;
once verified, tighten the large gland nuts.
Note:
Failure to center the gun in the burner throat will cause uneven
air flow and flame instability. The gun should be centered with
+/- 1/8".
