FIRE, INJURY OR DEATH HAZARD
Failure to £4tow this warning could result in electrical shocL
fire, personal injury or death.
Casing hole filler cap must be installed in blower shelf hole
when condensate trap is relocated.
4. Instal! condensate trap into right-hand side casing hole by
inserting tube connection stubs through casing hole and
rotating until tabs snap into locking position.
5. Fill unused condensate trap casing holes with plastic filler
caps (fi_ctoryosupplied in loose parts bag).
CONDENSATE TRAP TUBING
NOTE: See Fig. 13 or tube routing label on main f_./rnace door to
check for proper connections.
1. (ollector Box Drain Tube
a. Remove fitctoryoinstalled plug fiom LOWER collector box
drain robe (blue and white striped label).
b. Install removed clamp and plug into UPPER collector box
&ain tube (blue label) which was previously connected to
condensate t_ap.
c. Connect LOWER collector box drain robe (blue and white
striped label) to condensate trap. Tube does not need to be
cut.
d. (lamp robe to prevent any condensate leakage.
2. Inducer Housing Drain Tube
a. Remove fitctoryoinstalled cap and clamp from LOWER
inducer housing drain connection.
b. Remove and discard UPPER (molded) inducer housing
&ain tobe 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 robe (violet label and
factow-supplied in loose parts bag) to connect LOWER
inducer housing &ain connection to condensate trap.
e. Determine appropriate length, cut, and connect robe to
condensate trap.
£ Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section fbr connection
procedure.
CONDENSATE TRAP FIELD DRAIN ATTACHMENT
Refhr to Condensate Drain section fbr recommendations and
procedures.
PRESSURE SWITCH TUBING
One collector box pressure robe (pink label) is fi_ctory connected to
the pressure switch fbr use when i_urnace is installed in UPFLOW
or HORIZONTAL LEFT applications. This tube MUST be dis°
connected and used for the condensate trap relief port robe. The
other collector box pressure robe (green label) which was fhcto V
connected to the condensate trap relief port connection MUST be
connected to the pressure switch in DOWNFLOW or HORIZON°
TAL RIGHT applications.
NOTE: See Fig. 13 or tube routing label on main Nmace door to
check for proper connections.
Relocate tubes as described below.
1. Disconnect collector box pressure tube (pink label) attached to
pressure switch.
13
2. Extend collector box pressure robe (green label) which was
previously connected to condensate trap relief port connection
by splicing to small diameter robe (flactou-supptied in loose
parts bag).
3. (onnect collector box pressure robe (green label) to pressure
switch connection labeled COLLECTOR BOX.
4. Use remaining small diameter tube (factory-supplied in loose
parts bag) to extend collector box pressure tube (pink label)
which was previously connected to pressure switch.
5. Route this extended tube (pink label) to condensate trap relief
port connection.
6. Determine appropriate length, cut, and connect robe.
7. Clamp robe to relief port connection.
CONDENSATE TRAP FREEZE PROTECTION
Refer to Condensate Drain Protection section for recommenda-
tions and procedures.
CONSTRUCT A WORKING PLATFORM
Construct working platfbrm where all required furnace clearances
are met. (See Fig. 3 and 12.)

[NIT MAY NOT OPERATE
Failure to fbllow this caution may result in intermittent unit
operation.
The condensate trap MUST be installed below l::urnace See
Fig. 6 for dimensions. The drain connection to condensate
trap must also be properly sloped to an open drain.
NOTE: Combustionoair and vent pipes are restricted to a mini-
mun_ length of 5 ft (See Table 7.)
NOTE: A 12oin mininmnl of_;et pipe section is recommended
with short (5 to 8 ft) vent systems. This recommendation is to
reduce excessive condensate droplets fiom exiting the vent pipe.
(See Fig 12 or 35)
LOCATION
Step l--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 maximum lengths
are not exceeded. Refer to Table 7.
* be located where available electric power and gas supplies meet
specifications on the l::urnace rating plate.
* be attached to an air distribution system and be located as close
to the center of the distribution system as possible. Refer to Air
Ducts section
* be provided with ample space fbr servicing and cleaning.
Always comply with n_inimnm fire protection clearances
shown on the ft_rnace clearanceoto-combustibles label. (See
Fig. 3.)
This Nmace may be located in a confined space without special
provisions £_r dilution or ventilation air.
NOTE: For upflowidownflow applications install furnace so that
it is level or pitched fbrward within 1i2oin. for proper fitrnace
operation. For horizontal applications pitch 1i4oin. minimum to
1i2oin. maximunx forward to ensure proper condensate &ainage
from secondary heat exchangers. (See Fig. 14.)
