pane gas or propane gas to natural gas shall be installed
by a qualified service agency in accordance with the
manufacturer's instructions and all applicable codes and
requirements of the authority having jurisdiction. If the
information in these instructions is not followed exactly,
a fire, explosion, or production of carbon monoxide may
result causing property damage, personal injury, or loss of
life. The qualified service agency is responsible for the
proper installation of this furnace with these instructions.
The installation is not proper and complete until the
operation of the converted appliance is checked as
specified in these manufacturer's instructions.
AVERTISSEMENT: La conversion du gaz naturel au
gaz propane ou du gaz propane au gaz naturel doit être
effectuée par une agence de service qualifiée conformé-
ment aux instructions du fabricant et à tous les codes et à
toutes les exigences applicables de l'autorité compétente.
Si ces instructions ne sont pas observées exactement, il
peut en résulter un incendie, une explosion ou une
production d'oxyde de carbone pouvant résulter en dom-
mages matériels, lésions corporelles ou mort. L'agence de
service qualifiée est responsable d'installer correctement
cette
fournaise
conforément
L'installation n'est ni correcte ni complète tant que le
fonctionnement de l'appareil converti n'a pas été vérifié
de la manière précisée dans ces instructions du fabricant.
For accessory installation details, refer to applicable installation
literature.
APPLICATIONS
I. GENERAL
A downflow furnace application is where furnace blower is located
above combustion and controls section of furnace, and conditioned
air is discharged downwards.
Some assembly and modifications are required for furnaces
installed in either applications shown in Fig. 4 or 5. All drain and
pressure tubes must be connected as shown in Fig. 4 or 5.
Attach adhesive pouch containing literature packet and gas con-
version parts to side of furnace for use at a later date. (See Fig. 3.)
CAUTION: When installing the air conditioning coil
casing or when servicing air conditioning, caution must
be taken to ensure furnace will not fall forward. (See Fig.
7.)
CAUTION: To prevent damage during transportation of
the home, coil casing must be secured to the floor,
furnace and coil casing must be fastened together, and
furnace must be secured to wall of the structure. When a
coil casing is not used, an accessory floor base is
required. (See furnace rating plate or clearance label for
special accessory floor base part number.) Secure floor
base to structure and attach furnace to floor base.
RECOMMENDED METHODS OF SECURING FOR TYPI-
CAL INSTALLATION. (SEE FIG. 3.) ALL MOUNTING
HARDWARE IS FIELD SUPPLIED.
1. Secure coil casing to floor.
a. Secure coil casing to floor of structure using 5/16-in. lag
screws (one each side) through lower inside flanges of
coil casing.

b. Alternate method: Attach right angle mounting brackets
or pipe strap (bent 90 degrees) to coil casing using No.
10 self tapping screws. Attach other end of
brackets/strap to floor of structure using 5/16-in. lag
screws. If coil is present in casing, be careful not to
damage condensate pan with tip of screw or remove coil
from casing.
2. Fasten furnace to coil casing.
a. Secure furnace to coil casing using 2 No. 10 self tapping
screws (one on each side of burner enclosure) through
cell panel flange, lower furnace casing plate, and coil
casing top flange.
b. Alternate method: Attach pipe strap to both furnace
casing and coil casing (one each side). If coil is present
in coil casing, be careful not to damage it with tip of
screw.
1. Secure furnace to structure.
a. Attach pipe strap to top of furnace casing using No. 10
self tapping screws. Angle strap down and away from
back of furnace, remove all slack, and fasten to wall stud
of structure using 5/16-in. lag screws. Typical both sides
of furnace.
b. Alternate method: Secure furnace to wall stud using
1/8-in. thick right-angle brackets. Attach brackets to
furnace using No. 10 self tapping screws, and to wall
stud using 5/16-in. lag screws.
WHEN COIL CASING IS NOT INSTALLED (NOT SHOWN)
1. Accessory floor base MUST be used. Review floor base
Installation Instructions before installation.
2. Secure accessory floor base to structure using 5/16-in. lag
screws.
3. Fasten furnace to accessory floor base using No. 10 self
tapping screws through tabs on both sides of base (two each
side).
II. CONDENSATE TRAP INSTALLATION
1. Select condensate trap location from 1 shown in either Fig.
4 or 5.
2. If casing hole filler cap is installed in casing hole selected
for trap location, remove cap and install it in unused trap
location hole.
3. Install condensate trap (located in factory-supplied loose
parts bag) into selected location casing hole by inserting
tabs at top of trap onto upper edge of hole and rotating trap
until lower tabs fit into hole. Then allow trap to slide down
slightly and lock into position. (See Fig. 6.)
4. Connect collector box drain tube to condensate trap.
NOTE: See Fig. 4, 5, or tube routing label on main furnace door
to check for proper tube connections.
a. Condensate trap located on left-hand side of casing. (See
Fig. 4.)
(1.) Remove smooth collector box extension tube and
coupling from corrugated collector box tube and
discard.
(2.) Connect corrugated collector box tube to conden-
sate trap.
