2.7 Threaded Model FPD350.T4.E2 with Thin Wall Duct Mounting Plates (Option DF1)

Install the Torbar as follows:
1. Select the required insertion position and mark the pipe.
2. Drill a 6 mm (0.24 in) pilot hole at the marked position,
then drill to 28 mm (1.1 in).
3. Align the thin wall duct mounting plate and gasket
concentrically with the hole, ensuring the Torbar can pass
cleanly through the plate's threaded fitting and into the
pipe.
4. Drill through the thin wall duct mounting plate fixing holes
and gasket into the pipe. Do not separate the gasket from
the mounting plate.
5. Secure the thin wall duct mounting plate and gasket to the
pipe with rivets.
6. Measure exactly 180° around the pipe circumference and
mark the pipe.
7. Repeat steps 2 to 5.
8. Slide the compression-fitting assembly onto the Torbar.
9. Insert the Torbar through the threaded fitting into the pipe
until it enters the opposite fitting.
10. Apply appropriate sealant to the threads of the support
plug.

12. Apply appropriate sealant to the threads of the
compression fitting.
13. Screw the compression fitting into the threaded fitting until
hand-tight.
14. Turn the Torbar until the indentation marks on the head are
positioned downstream of the flow – see Fig. 2.1, page 3.
15. Holding the head of the Torbar with a wrench to maintain
correct orientation, use a long wrench to tighten the
compression fitting until approximately one thread is left
exposed under the nut, ensuring the Torbar does not turn.
16. Check that the Torbar is installed correctly and aligned.
