9.1) TUBE COUPLING DETAILS
Join the tube sections together and secure with tube couplings as described below. Note: The heater tube section
should be provided a slope of 0.25 degree up to the fan.
1.
Place the compression coupling over the end of the tube.
2. Use the small hole at the centerline of the coupling to check that the coupling is inserted correctly.
3. Partially tighten the bolt nearest the end of the tube (approximately half closed).

4.
Slide the next tube into the coupling.
5. Make sure both tube ends are butted together.
6. Finish tightening both bolts to 54-80 N·m torque to ensure a complete seal.
NOTE: Tighten the Torctite Coupling bolts alternately while continually checking for slackness of the joint.
7. Use the two self-drilling screws through the pre-punched holes to secure the tubes in the coupling.
