The nozzle kit consists of various components which you must identify and check as described in the following 

sections.
The 

Nozzle Installation Kit

 contains the materials listed below. Use 

Figure 5

 below to help identify each component.

IMPORTANT:

You will need to supply eight 5/8” studs with two nuts each (for 2” 150# flanges, 2” 300# flange or

3” 150# flanges), or 3/4” studs with two nuts each (for 3”, 300# flanges).

Figure 5: Components for Nozzle Installation Kit

Check the marking on the cylindrical surface of the welding boss. The pipe OD and the mounting angle are engraved 

on the boss as shown below.

• 2 Nozzles (if purchased)

• 2 Welding bosses

• 1 Jig

• 1 Threaded rod (1 in. diameter), washer and nut
