III. Place tubes over the hanger brackets with the welded seam facing down toward the ground. Failure to
assemble the tube with the seam facing down will void the manufacturer's warranty.
IV. Secure the tubes to each support/hanger bracket using U-bolt clamps and 5/16-18 nuts provided. See
Fig. 22 for required U-bolt tightening sequence.
4. Raise the tube section up to the suspension chain (or other methods), using "S" hooks to attach the tube
support brackets (close "S" hooks after they are attached to the hanger brackets). Hang each tube section
individually. DO NOT attach all of the heater tube sections together on the ground and attempt to hang the
entire system.
5. Suspend the hanger brackets for the remaining section of tube, raise the tubes into position and join the
tube sections together using Torctite couplings as described in Section 10.2 "Tube Coupling Details". Fasten
the tubes to the hanger bracket. See figures 22a, 22b and 22c for details of the assembly sequence and
hanger bracket attachment method. Refer to section 8.0 for the dimensions of the hanger bracket spacing.
