2. Inducer Housing Drain Tube
a Remove fhctoryoinstalled cap and clamp from LOWER
inducer housing drain connection.
b. Remove and discard UPPER (molded) inducer housing
drain robe which was previously connected to condensate
trap.
c. Install cap and clamp on UPPER inducer housing &ain
connection where molded &ain robe was removed.
d. Use inducer housing &ain extension tube (violet label and
factory-supplied in loose parts bag) to connect LOWER
inducer housing &ain connection to condensate trap.
e. Detem_ine appropriate length, cuL and connect robe to
condensate trap.
f\ Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section for connection
procedure.

Refer to Condensate Drain section %r recommendations and
procedures
PRESSURE SWITCH TUBING
One collector box pressure tube (pink label) is f'_ctory connected to
the pressnre switch fbr use when furnace is installed in UPFLOW
applications This tube MUST be disconnected and used for the
condensate trap relief port robe. The other collector box pressnre
robe (green label) which was fSctory connected to the condensate
trap relief port connection MUST be connected to the pressure
switch in DOWNFLOW or HORIZONTAL RIGHT applications
NOTE: See Fig. 12 or tube routing label on main filrnace door to
check for proper connections Relocate tubes as described below
1. Disconnect collector box pressure tube (pink label) attached to
pressure switch.
2. Extend collector box pressure tube (green label) which was
previously connected to condensate trap relief porq_connection
by splicing to small diameter robe (factov-supptied in loose
parts bag).
3. Route extended collector box pressure robe behind inducer
motor bracket then between inducer motor and pressure
switch,
4. Connect collector box pressm'e tube (green label) to pressure
switch connection labeled COLLE(TOR BOX.
5. Use remaining smaller diameter tube (gtctoryosupplied in
loose parts bag) to extend collector box pressure robe (pink
label) which was previously connected to pressure switch.
d. Route this extended robe (pink label) to condensate trap relief
port connection.
7. Detem_ine appropriate length, cut, and connect robe.
8. Clamp robe to relief port connection.

UNIT MAY NOT OPERATE
Failure to [bllow this caution may result in intem_ittent unit
operation.
The condensate trap MUST be installed below furnace See
Fig. 5 for dimensions. The drain connection to condensate
trap must also be properly sloped to an open drain.
NOTE: (ombustionoair and vent pipes are restricted to a mini-
mun_ length of 5 ft. (See Table 7.)
NOTE: A 12oin. mininmm of_;et pipe section is recommended
with short (5 to 8 ft) vent systems. This recomn_endation is to
reduce excessive condensate droplets fi'om exiting the vent pipe.
(See Fig. 11 or 34.)
LOCATION
Step t--General
This furnace must
* be installed so the electrical components are protected from
water
not be installed directly on any combustible material other than
wood flooring (refer to SAFETY CONSIDERATIONS).
* be located so combustion-air and vent pipe n_aximum lengths
are not exceeded. Re[_r to Table 7.
* be located where available electric power and gas supplies meet
specifications on the furnace rating plate.
* be attached to an air distribution system and be located as close
to the center of the distribution system as possible. Re['cr to Air
Ducts section.
* be provided with ample space fbr servicing and cleaning.
Always comply with nainimun_ fire protection clearances
shown on the furnace clearance-toocombustibles label.
This fi_rnace may be located in a confined space without special
provisions fbr dilution or ventilation air.
When a fm'nace is installed so that supply/lucts caro- air circulated
by d_e ftm_ace to areas outside the space containing the f'umace.
the return air shall also be handled by ducts sealed to filrnace
casing. The &lcts terminate outside the space containing the
ft_rnace to ensure there will not be a negative pressure condition
within equipment room or space.
NOTE: For upflowidownflow applications install furnace so that
it is level or pitched [brward within 1i2oin. for proper furnace
operation. For horizontal applications pitch 1/4-in. minimtml to
1i2oin. maxinmnl forward to ensure proper condensate &ainage
from secondary heat exchangers. (See Fig. 13.)
