FAILURE TO PREVENT PRODUCTS
OF COMBUSTION FROM BEING CIR-
CULATED INTO THE LIVING SPACE
CAN CREATE POTENTIALLY HAZ-
ARDOUS CONDITIONS, INCLUDING
CARBON MONOXIDE POISONING
THAT COULD RESULT IN PERSONAL
INJURY OR DEATH.
DO NOT, UNDER ANY CIRCUM-
STANCES, CONNECT RETURN OR
SUPPLY DUCTWORK TO OR FROM
ANY OTHER HEAT PRODUCING
DEVICE SUCH AS A FIREPLACE
INSERT, STOVE, ETC. DOING SO
MAY RESULT IN FIRE, CARBON
MONOXIDE POISONING, EXPLO-
SION, PERSONAL INJURY OR PROP-
ERTY DAMAGE.
WARNING
BLOWER AND BURNERS MUST
NEVER BE OPERATED WITHOUT
THE BLOWER DOOR IN PLACE. THIS
IS TO PREVENT DRAWING GAS
FUMES (WHICH COULD CONTAIN
HAZARDOUS CARBON MONOXIDE)
INTO THE HOME THAT COULD
RESULT IN PERSONAL INJURY OR
DEATH.
UPFLOW UNITS
1. Set furnace in place and connect the
return duct or return air cabinet to
unit. Make the connection air-tight to
prevent entraining combustion gases
from any adjacent fuel-burning appli-
ances. Unit return air may be con-
nected on the sides or bottom of the
return air compartment.
a. Openings in the side must be cut
out the full width of the knockouts
on the unit. If using side return air,
THE BOTTOM base plate must be
installed.
NOTE: Where the maximum airflow
is 1800 CFM or more, both sides or
the bottom must be used for return
air.
b. If using bottom return air, place fur-
nace over return air plenum and
seal furnace bottom to return air
plenum.
WARNING
A SOLID METAL BASE PLATE, (SEE
TABLE 1) MUST BE IN PLACE WHEN
THE FURNACE IS INSTALLED WITH
SIDE AIR RETURN DUCTS. FAILURE
TO INSTALL A BASE PLATE COULD
CAUSE PRODUCTS OF COMBUS-
TION TO BE CIRCULATED INTO THE
LIVING SPACE AND CREATE POTEN-
TIALLY HAZARDOUS CONDITIONS,
INCLUDING CARBON MONOXIDE
POISONING OR DEATH.

2. If summer air conditioning is desired,
position the indoor coil on the supply
air side of the furnace. Insure that no
air can bypass this coil.
3. Connect the supply air plenum to the
furnace plenum opening, or indoor
coil.
NOTE: The RGLE has louvers to cool
the inducer motor bearings.
DOWNFLOW UNITS
WARNING
THE DOWNFLOW FURNACE DESIGN
IS CERTIFIED FOR INSTALLATION
ON A NON-COMBUSTIBLE FLOOR.
IF INSTALLED ON A COMBUSTIBLE
FLOOR, USE THE SPECIAL BASE
SPECIFIED ON THE FURNACE
CLEARANCE LABEL. FAILURE TO
INSTALL THE SPECIAL BASE MAY
RESULT IN FIRE, PROPERTY DAM-
AGE, PERSONAL INJURY OR
DEATH. THIS SPECIAL BASE IS
SHIPPED FROM THE FACTORY AS
AN ACCESSORY.

COMBUSTIBLE FLOOR BASE (RXGC-B17, -B21, -B24)
1. Position the unit over the supply
air plenum and connect.
a. If installing on a combustible
floor and not using an evapo-
rator coil box, install the spe-
cial combustible floor base. See
Figure 5.
b. If summer air conditioning is
desired, position the indoor coil
on the supply air side. Insure
that no air can bypass this coil.
2. Connect the return air ducting to
the return air opening at the top of
the unit. Make the connection air
tight to prevent entraining com-
BASE
bustion gases from an adjacent

1. Unit can be mounted left or right
side airflow configuration.
2. Position the unit on adequate
supports or by using support
brackets (see Figure 2) and con-
nect supply plenum and return.
3. If summer air conditioning is
desired, position the indoor coil
on the supply air side of the unit.
Insure that no air can bypass this
coil.
4. Secure the four angle brackets
shipped with the unit to the return
air opening. See Figure 6.
Connect the return air ducting to
the return air opening at the top of
the unit. Make the connection air
tight to prevent entraining com-
bustion gases from an adjacent
fuel-burning appliance.
NOTE: Do not block furnace access
with support rods. Maintain clear-
ances recommended in Figure 3.
Allow enough space for proper ser-
vice maintenance or replacement of
the heat exchanger and blower
assembly.
