Mounting Your Furnace
To obtain adequate clearance for fastening the furnace or to install
gas supply fittings, it may be necessary to remove the burner and
control assembly as follows:
CAUTION: Be careful not to damage burner pan
gasket when removing burner and control assembly.
1. Lay the furnace on its back for the following steps.
Remove burner compartment door by pulling the door top out
and up.

a. Remove the screws holding the ignition control unit and the
cover to the casing.
b. Remove (3) screws „A‟ holding the burner pan to the upper
heating element support (Page 17, Fig. 22). Rotate the
burner pan toward the front until the (3) pins „B‟ disengage
from the upper heating element support.
c. Remove necessary wiring to free the control module from
its mounting location. Mark or tag each wire removed for its
exact reconnection (Page 17, Fig. 23).
d. Remove the burner and control assembly from furnace.
MODELS: 4007732, 6007732

the (2) screws and disconnecting the wire at the back of
the igniter.

from the gas valve.
c. Remove the (3) screws „A‟ holding burner pan to the upper
heating element support (Page 17, Fig. 22). Rotate the
burner toward the front until the (3) pins „B‟ disengage from
the upper heating element support slots.
d. Remove the burner and control assembly from furnace.
NOTE: Attach vent tubes BEFORE mounting the furnace. See
Pages 14 & 15.
2. If furnace is recessed in the wall, clear the recess of all debris.
3. Be sure the gas is shut off at the meter.
4. Before placing the furnace in position, remove the gas piping
stub if necessary to locate the furnace.
5. After installing the vent tubes, carefully move the furnace into
position, being sure not to bend the vent tubes.
FASTEN FURNACE BOTTOM
(SURFACE AND RECESSED MOUNT)
NOTE: Fasteners are not furnished because of different
requirements of various types of wall construction.
Fasten the furnace to the floor through the holes provided in the
furnace bottom. If you have concrete flooring, use an alternate
fastening method. See Page 17, Fig. 21.
If the burner and control assembly were removed, replace them
by reversing steps 1a through 1d.
IMPORTANT: When replacing the burner and control assembly,
be sure that pins “B” all enter the slots in the upper heating
element support. To prevent damage to wiring, be careful not to
pinch them between furnace components and route them away
from the burner pan surface.
