Fig. 3 – Condensate Trap Plumbing Options for Combustion Air Pipe (ONLY) Above Furnace
INSTALLATION
In this application, ALL vent piping MUST be sloped toward the
External Vent Trap Kit. The Internal Drain Trap Plug MUST be installed
in the vent/high-pressure side of the collector box trap connection in the
furnace (see Fig. 3 ). The Trap Kit MUST be installed at the lowest point
in the venting system.
Example Trap Kit component installations are shown in Fig. 1 . Install as
shown in Fig. 3 through Fig. 7 .
NOTE: NOTE: This kit is designed for use with 2-in. (50 mm)
PVC/ABS DWV vent/exhaust pipe applications. Additional pipe
diameters are usable when field-supplied PVC fittings are used with the
condensate trap supplied in kit (see Fig. 9 ) for proper placement of pipe
diameter transitions.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in personal injury or
death.
The Internal Drain Trap Plug MUST BE APPLIED to the vent side of
the collector box trap connection of the furnace when the trap kit is
applied to the vent/exhaust piping system. Failure to do this may result
in vent gasses being released into the living space.
Failure to use a properly constructed trap(s) or NOT water-priming
trap(s) before operating furnace may allow positive pressure vent gases
to enter the structure through drain tube. Vent gases contain carbon
monoxide which is tasteless and odorless.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution could result in intermittent unit operation.
When the Internal Drain Trap Plug is used, the inducer housing may fill
with condensate if any of the vent piping that is external to the furnace
is sloped toward the furnace.
NOTICE
!
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 Table 2 ). See section for Special Venting
Requirements in the furnace installation instructions Venting section 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 and primers 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.
