Instruction Manual – Model AFG Oil Burner

Prepare burner & site

Check/adjust "Z" dimension - "L1" head

Check/adjust "Z" dimension - "V1" head

Figure 3 — “L1” heads (see Table 3 and Figure 2 for dimensions)

1.See Figure 3.￿The important "Z" dimension is the distance from the leading edge of the head to the end of the air tube.￿This distance for L1 heads is 1 ³⁄₈" if the tube has a straight shroud (1 ³⁄₄" if the air tube has a conic shroud).￿The "Z" dimension is factory set for burners shipped with the air tube installed.￿Even if factory set, verify that the "Z" dimension has not been changed.

2.Use the following procedure to adjust the "Z" dimension, if it is not correct:

•Turn off power to the burner.

•Disconnect the oil connector tube from the nozzle line.

•See Figure 3.￿Loosen the splined nut from the nozzle line.￿Loosen the hex head screw securing the escutcheon plate to the burner housing.

•Place the end of a ruler at the leading edge of the head and, using a straight edge across the end of the tube, measure the distance to the

￿end of the air tube.￿(A Beckett T500 gauge may also be used.)

Slide the nozzle line forward or back until this dimension is 1 ³⁄₈" for L1 heads if the air tube has a straight shroud (1 ³⁄₄" if the air tube has a conic shroud).

•Tighten the hex head screw to secure the escutcheon plate to the burner chassis.￿Then tighten the splined nut and attach the oil connector tube.

3.Recheck the "Z" dimension periodically when servicing to ensure the es- cutcheon plate has not been moved.￿You will need to reset the "Z" dimen- sion if you replace the air tube or nozzle line assembly.

Figure 4 — “V1” heads (see Table 3 and Figure 2 for dimensions)

1.See Figure 4.￿The important "Z" dimension is the distance from the leading edge of the head to the end of the air tube.￿This distance for V1 heads is 1 ³⁄₄". The "Z" dimension is factory set for burners shipped with the air tube installed.￿Even if factory set, verify that the "Z" dimension has not been changed.

2.Use the following procedure to adjust the "Z" dimension, if it is not correct:

•Turn off power to the burner.

•Disconnect the oil connector tube from the nozzle line.

•See Figure 4.￿Loosen the splined nut from the nozzle line.￿Loosen the hex head screw securing the escutcheon plate to the burner housing.

•Loosen the acorn nut.￿Move the head adjusting plate until the "0" lines up with the reference indicator on the housing, and retighten the hex head screw.￿Place the end of a ruler at the leading edge of the head and, using a straight edge across the end of the tube, measure the distance to the end of the air tube.￿Or use a Beckett T500 gauge.￿Slide the nozzle line forward or back until this dimension is 1 ³⁄₄" for V1 heads.￿Tighten the acorn nut.

•Tighten the hex head screw to secure the escutcheon plate to the burner chassis.￿Then tighten the splined nut and attach the oil connector tube.

3.Recheck the "Z" dimension periodically when servicing to ensure the es- cutcheon plate has not been moved.￿You will need to reset the "Z" dimen- sion if you replace the air tube or nozzle line assembly.

Set head position adjusting plate (“V1” head only)

1. After setting “Z” dimension, loosen head adjusting plate hex head screw and

2. Tighten the hex head screw and splined nut. (DO NOT loosen the acorn nut when setting head position.) Refer to the Beckett OEM Specification Guide or manufacturer's instructions for OEM settings.

3. The position of the head affects air flow volume and pattern. For most applications, the burner will perform satisfactorily with the air adjustment plate setting of Table 3.

4. If combustion results indicate the need for change, adjust the head position adjusting plate forward or back one position at a time to optimize combustion.
