1. Cut a 2 ⁄ " diameter hole in sole plate, header or stud directly
2
in line with opening of inlet bracket fitting. Note Figures 6
and 4 for center line dimensions.
2. Refer to Figure 7. Measure length of tubing needed to
connect inlet to trunk line. Allow approximately
for inserting into fittings.
3. Refer to Figure 8. Cut tubing, keeping cut square.
4. Refer to Figure 9. Remove burrs from both inside and
outside of tubing.
5. Before cementing, pre-assemble section to inlet fitting,
check for proper length.
6. Refer to Figure 10. Apply cement to outside of tubing.
Coat tubing approximately 1" back. Take care to keep
cement from inside of tube.
7. Refer to Figure 11. Insert tubing into fitting with a twisting
motion to evenly spread cement. Be sure tubing is firmly
seated in fitting.
8. If fittings have been attached to tubing at the end opposite
the inlet bracket, be sure alignment is proper before
cement sets.
9. Refer to Figure 12. Low voltage wiring should be completed
as tubing is installed. Tape wire to tubing to hold in place
and insert through hole in inlet bracket.
NAIL PLATE INSTALLATION
CAUTION: When tubing is run through the wall stud, sole
plate, headers - or anywhere that building materials will
be attached - place a nail plate over that area (on both
sides if necessary) to prevent nails from piercing tubing.
