Mark the centers of the top and bottom
ManaBloc ports (A, B)
5. Standing in front of the wall, using a framing square
or straight edge, mark the center line position of
the top and bottom ports onto both studs. (See
illustration.)
6. Detach the ManaBloc from its mounting straps (or
1x4s) and remove it from the installation area to
prevent wood chips or other debris from falling into
the unit.
7. Transfer the port location marks made in Step 5
to the insides of the stud cavity using a square
and pencil.
8. Measure 1⅝" from the mounting surface. Draw a
vertical line on the studs that passes through each
of the horizontal port center lines marked in Step 7.
(See illustration below.) Be sure to mark the inside
of both studs.
9. Push a small nail through the printed center line at
one end of the Drill Guide (A). Push the nail into the
cross formed where the top port mark intersects
with the 1⅝" mark. Tap the nail into the stud to
hold the Drill Guide in place.
10. Push a small nail through the printed center line on
the lower end of the Drill Guide with the center line
of the port (B). Tap the nail into the stud to hold
the Drill Guide in place.
1⅝"
11. Using an awl, nail or other pointed tool (C), mark
the stud by tapping through the Drill Guide at each
printed center line between the two nails.
12. Carefully remove the Drill Guide and repeat the
marking procedure on the adjacent stud.
13. Drill ¾" holes through both studs at each
marked location. Be sure to hold the drill level
perpendicular to the stud to prevent drilling holes
at an angle. Remove any splinters or burrs made
during drilling.
14. Mark and drill any holes for main water supply
and hot water supply/return lines at this time. A
1¼" bit will provide adequate clearance for ¾" or
1" tubing. The tubing shall enter and/or exit the
ManaBloc in a straight line so as not to induce
bending stress on the ManaBloc. Necessary
elbows, couplings and tees are allowed in the main
water supply lines.
