Several varieties of special inlet and outlet fittings have been developed for use with these Sections. Methods of installations are:

  1. For "AX" Sections, offset inlet and outlet manifold headers may be made up utilizing tees, figure 19 of appropriate size with Z flange ells, figure 20 connecting the Sections to the headers.

  2. When using Sections submerged in a box special extension pieces are used to connect the overhead manifold and the bottom outlet can be carried through the partition by a tank nozzle.

The letter "Z" in the casting mark indicates the fitting is for use with Types AX Sections. ZNP denotes nipple port opening for push nipple application.



Fig. 19.
Z flange ell shown here is used to offset headers made up of AX cast iron tees. It is suitable for use in connecting 4", 6", or 8" tees to Types AX Sections. By offsetting the tee headers, assembly is made easier and it is possible to blank off one or more stacks for repairs while operating the balance of the installation. Casting mark ZL6-Z. Weight 50 lbs. Also furnished with nipple connections to Sections marked ZL6ZNP which is the same except for port details
