• Welded seam of combustion tube facing downward
(in the bottom hemisphere)
2. Slide tube coupler on to combustion tube
(past the rivet hole in tube)

next tube and locking the joint using the Torctite coupler. SEE FIGURE 9.
NOTE: For the 3rd and following tubes in the system: DO NOT install the welded seam facing
downward along the length of the system after the first two tubes. Welded seams should ran-
domly face toward one side or the other (3 or 9 o’clock), 90° up from bottom (6 o’clock).
