TUBING INSTALLATION
1. Cut a 2 1 ⁄
2
" diameter hole in sole plate, header or stud directly
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 3 ⁄ 4 " of tubing
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 (Model 379) 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 (Model 376) 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 (Model 378) over that area
(on both sides if necessary) to prevent nails from piercing
tubing.
