When the MANABLOC includes a
divider plate, also mark the location
of the ports directly above and
b
elow the divider plate onto both
studs.
6. Detach the MANABLOC from its
Mounting Straps (or 1 x 4s) 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 1-5/8" 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).
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 1-5/8"
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 Drill
Guide with the center line of the
ports above the divider plate (B).
Tap the nail into the stud to hold
the Drill Guide in place.
If the MANABLOC does not have
a divider plate, push the nail into
the printed center line of the
b
ottom most port (E) and on into
the corresponding mark on the
stud. Tap the nail into the stud
to hold the drill guide in place.
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. Carefully remove the
Drill Guide. If the MANABLOC
does not have a divider plate, go
to step 13.
12. Marking port locations below a
divider plate: Put the top nail in the
Drill Guide (D) on the cross
formed by the center line of the
first port below the divider plate
and the 1-5/8" measurement from
the back of the stud. Tap the nail
into the stud to hold the drill guide
in place. Push another nail (E)
through th center line on the Drill
Guide which corresponds to the
bottom port of the MANABLOC.
Then place the nail at the point on
the stud where the bottom port
center line intersects with the
1-5/8" measurement. Tap the nail
into the stud to hold the drill guide
in place. With a nail or awl (F), tap
and mark the stud at each center
line between the two nails.
13. Carefully remove the Drill Guide
and repeat the marking procedure
on the adjacent stud.
14. Drill 3/4" holes through both studs
at each marked location. Be sure
to hold the drill level and
perpendicular to the stud to
prevent drilling holes at an angle.
Remove any splinters or burrs
made during drilling.
15. Mark and drill any holes for main
water supply and hot water
supply/return lines at this time.
An 1-1/4" bit will provide adequate
clearance for 3/4" or 1" tubing.
The tubing shall enter and/or exit
the MANABLOC in a straight line
Drill 3/4" holes
for distribution
lines; 1-1/4"
holes for
supply lines.
