INTRODUCTION
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
Do not use this kit with variable- -speed furnaces.
Variable- -speed inducer pressure could force water out of
this trap and permit vent gas to leak into living space.
This instruction covers installation of the vent/exhaust pipe
external trap kit P/N KGAET101ETK in all fixed- -capacity,
multipoise condensing gas furnaces listed in Table 1.

DESCRIPTION AND USAGE
Use this vent/exhaust pipe external trap kit to reduce gurgle noise
concerns and/or to improve condensate draining in vent/exhaust
pipe.
This vent/exhaust pipe external trap kit contains the following
items:
Condensate trap
Tee vent fitting (2-in. (51 mm) PVC)
Bushing vent fitting (2 x 1-1/2-in. (51 x 38 mm) PVC)
Adapter fitting (1-1/2 (38 mm) male x 1-1/2 (38 mm)
female)
INSTALLATION
These instructions are written assuming kit is installed after
furnace and vent system have been installed and is operational.
Kit components and alternate methods of condensate plumbing
are shown in Fig. 1. If installing kit during initial installation,
install as shown in Fig. 2 through 9.
NOTE: This kit is designed for use with 2- -in. (51 mm) PVC
vent/exhaust pipe applications. Additional pipe diameters are
usable when field- -supplied PVC fittings are used with
condensate trap and bushing supplied in kit.
Drain pipe and fittings must conform to ANSI standards and
ASTM D1785 or D2846. CPVC or PVC cement and primer must
conform to ASTM D2564 or F493. See section for Special
Venting Requirements for installations in Canada for pipe,
fittings, cement, and primer material requirements for Canadian
installations.
WARNING
!
FIRE HAZARD
Failure to follow this warning could result in personal
injury, death or property damage.
Solvent cements are combustible. keep away from heat,
sparks and open flame. Use only in well- -ventilated areas.
Avoid breathing in vapor or allowing contact with skin or
eyes.
NOTE: Slope combustion- -air and vent pipes a minimum of 1/4- -
in. (6 mm) per linear ft. with no sags between hangers.
CAUTION
!
UNIT OPERATIONAL HAZARD
Failure to follow this caution may result in intermittent unit
operation.
This kit is intended to be located at the lowest point in the
vent system and no more than 24 in. (610 mm) horizontally
from where the vent exits the furnace to achieve proper
drainage.
