I. 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.
II. Secure the tubes to each support/hanger bracket using U-bolt clamps and 5/16-18 nuts provided. See
Details A or B of Fig. 21 and 21a 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. For models ADU 30/35 suspend the hanger bracket for the second 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 figure 21b, c and d below for installation
sequence.
