Figure 12C - Examples of Configurations with the Tail Pipe Adjacent to a Straight Heat Exchanger Tube
To install turbulator:
1) Attach the tail pipe to the straight
pipe.
2) Insert a turbulator section into the
tail pipe.
3) Interlock turbulator sections as
they are inserted (See Figure
12B).
4) Continue until all required sec-
tions are in place.
Figure 12D - Examples of Configurations that require more than three turbulator
strips and have the tail pipe adjacent to an "L" or "U" heat exchanger tube
To install turbulator:
1) Before attaching the "U" or "L" tube,
insert two interlocked turbulator sec-
tions (See Figure 12B) into the last
straight tube.
2) Attach the "U" or "L" heat exchanger
tube to the straight tube.
3) Attach the tail pipe to the "U" or "L"
tube.
4) Insert three interlocked turbulator
sections into the tail pipe.
4) Level the System and Close "S" Hooks
Tubes must be level. Use a spirit level and adjust the turnbuckles or chain links. Close all "S" hooks being careful not to change the chain length. When
the system is level, re-check to be sure that all bolts connecting the tubes are tightened securely.
Straight systems should be straight; systems with "L" tubes should be at right angles; and "U" shaped systems should be parallel.
