CLOSE OFF STUD SPACE (IF REQUIRED)
If studs are not on 16-inch centers, cut the hole for the
furnace next to an existing stud and frame in the other
side using a 2 x 4 and spacer blocks as required. Figure 6

CEILING PLATE OPENING
Cut away the ceiling plate between the studs where the furnace is to
be installed. Work from the top in the attic. If there is no access to the
top, remove the wall covering between the two wall studs all the way
to the ceiling. Work through this opening. Cut out the entire plate
so the plate edges will be even with the inner face of the
2 x 4 studs. Figure 7
INSTALL VENT BASE PLATE (HOLD-DOWN PLATE)
Position base plate on top of header plate and fasten with screws.
Note: Hold down plate is not included.
HEADER PLATE (VENT SUPPORT)
Measure upward 62¼-inches from the top of the floor plate. Place a
mark on each stud at this distance. Figure 5. Place the header plate
between the studs with the lower edges even with marks on the
studs. Make sure header plate is level.
Locate rear edge of nailing tabs at back of the header. Nail header
plate to the 2 x 4 studs which will center the vent collar in the wall.
Figure 5
INSTALL CEILING PLATE SPACER
Nail the ceiling plate spacers either across or in between the cut out
section of ceiling plate. If nailed between, ends must be bent at 90
degrees. They must be fastened along each long edge of the ceiling
plate hole to hold the oval vent pipe in the center of the hole. Ceiling
plate spacers preserve structural strength and position oval vent pipe
in the center of the cut out opening. Ceiling plate spacers are not
included. Figure 7

SURFACE MOUNT INSTALLATION

The use of the optional Free Standing Accessory No. 4901 allows
single-sided furnaces to be surface mounted instead of recessed
into a wall. This is ideal for remodeling existing masonry wall
construction or when studding is substandard. This kit drastically
cuts installation time and eliminates the expense of cutting into the
walls and ceiling plates. Be sure this accessory is of the type and
design required for the use with your furnace.
NOTE: After picking a location that meets the requirements, check
the wall, attic, and roof to make sure there are no obstructions
such as pipes, electrical wiring, etc., which could interfere with the
installation of the furnace or vent pipe. If required, move them or
pick a new location.
FIND THE WALL STUDS OR CEILING JOISTS
Find two studs or joists at the spot where the furnace is to be
located. Use a stud locater or small finishing nails. Repeatedly
drive and remove a nail into the wall or ceiling in the area of the
stud or joust until you find it. Then find the its side and leave the
nail there. Drive another nail just on the other side other the same
stud or joist.
The inside of the next stud or joist should be about 14 1/2 inches
from the first one found. Drive a nail on the inside of this stud or joist.
Using the nails as a guide, draw two lines down the side of
the wall from the ceiling to locate the furnace and ceiling
hole cutout for venting.
