Be sure to hold wire perfectly horizontal so that
both interior and exterior holes line up with one
another. Check for inner wall obstructions by
bending short length of coat hanger wire at a
right angle and twirling this right angle piece
inside the wall.
Drill a 2 1/4" (5.7cm) hole horizontally through
both sides of wall.
Make the hole in the exterior wall surface into
the same shape opening as described previ-
ously in
STEP 1 - (Installing Inlet Valves) (Fig. 4).
From inside closet, cut 2-1/4" (5.7cm) hole
through floor, either directly below opening in
wall or at convenient spot. (Caution: - Make
pilot hole as in STEP 1 previously.) Run low-
voltage wire through 2-1/4" (5.7cm) hole in
floor, and through wall to exterior of closet.
Pass low-voltage wire through the wire guide
hole of the
inner wall closet assembly
(Fig.
15) and tape low-voltage wire to this assembly
immediately behind the metal bracket.
Attach wires to low-voltage terminals at rear of
inlet
valve.
Place inner wall assembly lengthwise through
wall opening and arrange assembly so that
metal bracket is flush with inside surface of
wall. Screw inlet to wall as described previous-
ly in STEP 1, then complete as per (Fig. 16).
f) Wall Valve Installation—New Construction
Select a probable location for inlet valve and
drill a pilot hole in the floor. Go below to check
that tubing path is clear of present,
or future
,
obstructions such as floor joists, heating ducts,
plumbing, wires, etc.
At intended inlet valve location, drill a 2-1/4"
(5.7cm) diameter hole through sole plate. To
pinpoint center of hole, measure over 2"
(5.1cm) from side of stud and 2" (5.1cm) from
front of sole plate (Fig. 17).
Glue a length of tubing into a stud-mounting
bracket assembly. Cut a length of low-voltage
wiring, bring approximately 6" (15.24cm)
through top wire guide hole in stud bracket
assembly and double it back into elbow hole.
Tape wire to tubing at assembly elbow and
again close to end, and tuck remaining wire
into bottom of tubing.
