4.3 Drilling Tubing Holes

14 of 40
If support crosses can be easily removed, take them out to clear bays
for easier installation of the plates and Traks. If crosses are unable to be
removed, DO NOT drop tubing below them and resume on the other side;
install both plates and tubing above crosses so that no area is lost. Nails
must also be removed from bays. Whether you cut them, grind them,
or carefully bend them over, be careful not to damage the finished floor
above. (When cutting nails, be sure to wear safety glasses.)
Determine where the manifold will be located, then from there, decide
which end of the bays the tubing will be returning down. Use a right
angle drill with a 1¼" bit to drill a series of holes through each floor joist.
Be sure to keep holes at least 3" from the subfloor to avoid floor nails,
although having the holes centered would be the best for structural
strength.
Map out the circuits and determine which bays go to which circuits. Be
careful not to exceed maximum circuit length for the size of tubing you
are using (⅜" - 300 ft., ½" - 400 ft.).
Be sure to check with local building codes to ensure no
structural damage will occur with drilling the joists.
