Installation
•
Tighten the cradle loops of the first hanger with the “J-Bolt” found in the burner box, to snugly
hold the combustion tube from rotating see Figure 12.
Note:
For all coupling joints, ensure that the tube joint is in the center of the coupling
length, and that the overlap joint of the coupling is above the centerline of the tube. Also
ensure that the weld seam on ALL tubes is facing down.
Note: In order to obtain smoothly sealed coupling liners, tighten each of the coupling
bands progressively and alternately. Tightening one band completely before the other may
result in an undesirable wrinkle in the liner (refer to
Figure 12
). Be sure not to over
torque the coupling. (Torque coupling to 15-25 lbf-ft).

•
Continue placing tubes, couplings and reflectors to complete the heater assembly. Ensure heat
exchanger sections line up straight. Couplings should be tightened as heat exchanger is placed,
since it is more difficult to do so once the reflector is in position.
