RECESSED WALL MOUNT INSTALLATION

Recessed wall mount installation on models:
C255H / C256H / C355H / C356H / C505H / C506H
The maximum recess depth from rear of furnace forward
is 4 1/2-inches.
FIND THE STUDS AND CEILING JOINTS
Use a stud locater or small finishing nails. Repeatedly drive and
remove a nail into the wall in the area of the stud until it is located.
Then find the inside edge of the stud. Leave the nail at this location.
The other stud should be about 14 1/2-inches from the one found.
Drive finishing nails on the inside of this stud. Draw wall cutout to
required size as shown in Figure 5. If wall studs are not on 16-inch
centers. See "CLOSE OFF STUD SPACE." Figure 6
CUT WALL OPENING
Cut wall opening 14"-inches wide and 66"-inches high measured
from the top of the floor plate. Figure 5. All corners must be square.
INSTALLATION OF REAR OUTLET REGISTER
The optional rear outlet register may be installed when the furnace
is recessed into the wall. In new construction, install the rear outlet
plaster ground at the same time you install the header plate. For
existing construction, make the necessary cutout and install the
plaster ground before you install the furnace. See instructions packed
with accessory and Figure 5.
Do not allow wall finish material to project into the
furnace recess.
Do not install rear outlet register where grille may be blocked by a
door, curtains or any other obstruction.
GAS SUPPLY OPENING
A hole must be drilled for the gas line. Decide whether the gas line
will come through the floor or wall. Drill a 1 1/2-inch hole through the
floor or wall as needed. Figure 5.
CAUTION: Be careful not to damage any furnace components
while making any alternate hole.
