screwdriver to pry the wall plate latch arm away from the thermostat chassis to release

Installation in
Existing
Construction
Concealed Piping
Solid or Semisolid Walls—If the wall in which the thermostat is to be located is solid, or
the terminal leads cannot be "snaked" through the wall, a portion of the wall must be
removed to accept the terminal and tubing. Generally, the wall box Kit No. 192-478 or
192-480 is more suitable for this type of installation.
Hollow Walls -- Many types of wall construction are sufficiently hollow so that the
thermostat terminal can be installed without damaging the finished surface, Generally,
the tubing Kit No. 192-481 is best suited for this installation. Other tubing kits suitable for
finished wall installation may also be used.
