Vent Located in Unconditioned Space
Vent Pipe and Condensate Drain Protection
Freezing condensate in condensate traps and drain lines may cause
cracks, and possible water damage may occur. Refer to the Maximum
Allowable Exposed Vent Lengths in Unconditioned Space limitations in
the furnace installation instructions.
Layout and Dry Fit Venting System
Layout and install the venting and/or combustion-air inlet system(s) as
follows:
1. Determine the best location for kit components. They should be
installed as close to furnace as possible (see Fig. 4 through Fig. 8
for examples).
2. Size the venting system per the instructions provided with the
furnace.
3. Dry-fit and assemble vent/exhaust and/or combustion-air inlet
piping per the instructions provided with the furnace, except that
the Trap Kit is placed at the lowest point of the vent/exhaust and/or
combustion-air inlet piping system (see Fig. 4 through Fig. 8 for
examples).
4. Cut section of vent/exhaust pipe to attach the trap-tee fitting, using
the examples in Fig. 1 , Fig. 2 and Fig. 2 through Fig. 8 .
NOTE: Position vent-tee fitting such that curved portion is as shown in
Fig. 1 and Fig. 2 to ensure proper vent/exhaust and/or combustion-air
inlet pipe draining.
5. Dry fit the trap-tee fitting into the venting and/or combustion-air
inlet piping system.
6. Verify the proper slope of the entire vent/exhaust and/or
combustion-air inlet piping system to the trap-tee(s). ALL
vent/exhaust piping between the furnace and the Trap Kit should be
sloped DOWN and AWAY from the furnace.
7. Cement all vent and/or combustion-air inlet piping in place, per the
instructions provided with the furnace.
Drainage System Layout and Installation
The furnace, indoor coil, and humidifier drains may be combined and
drained together. The indoor coil drain must have an external,
field-supplied trap prior to the furnace drain connection, and/or spill into
an open stand pipe (see Fig. 1 & Fig. 2 ). All drain connections (furnace,
indoor coil, or humidifier) must be terminated into an open or vented
drain as close to the respective equipment as possible to prevent
siphoning of the other equipments’ drains. See equipment installation
instructions for more information.
Outdoor draining of the furnace is permissible if allowed by local codes.
Use the accessory acid neutralizer kit as required by the application (to
protect shrubs, etc.), or as required by local codes.
Condensate is not to be drained onto crawlspace floor from furnace or
external trap. Installations must comply with regulations of local
building, heating, plumbing, or other codes in effect in area where
installation is made.
Complete the installation of the drainage system as follows:
1. Dry fit the external condensate drain trap supplied with the kit into
the vent trap-tee fitting. Apply field-supplied fittings as required if
the 2-in. (50mm) trap-tee supplied with the kit was not used.
2. Position the external condensate drain trap as required to match to
the condensate drainage piping system.
CAUTION
!
UNIT OPERATIONAL HAZARD
Failure to follow this caution may result in intermittent unit operation.
The combustion-air inlet piping system must not have any sections
where moisture may collect and block the flow of combustion air
through the piping system. If water does block the inlet pipes, the
furnace will not operate, or operate intermittently.
CAUTION
!
UNIT OPERATIONAL HAZARD
Failure to follow this caution may result in intermittent unit operation.
Unit must not be installed, operated, and then turned off and left in an
unoccupied structure during cold weather when temperature drops to
32°F (0°C) and below unless drain traps and drain lines have adequate
freeze protection. See Service and Maintenance Instructions for
winterizing procedure.
CAUTION
!
UNIT OPERATIONAL AND PROPERTY DAMAGE
HAZARD
Failure to follow this caution may result in intermittent unit operation,
and may cause frozen and/or burst indoor plumbing and property
damage.
Caution should be taken to prevent condensate trap(s) and drain line(s)
from freezing. Ambient temperatures below 32°F (0°C) may freeze
drain pipe and prohibit draining. If freeze protection is required, use a
self-regulating, shielded, and waterproof heat tape rated at 3 to 6 watt
per ft. (10 to 20 watt per meter) at 120v and 40°F (4°C). See Installation
Instructions supplied with accessory condensate trap heater, accessory
heat tape, or heat tape manufacturer’s recommendations.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution could result in intermittent unit operation.
The inducer housing may fill with condensate if any of the vent piping
that is external to the furnace is sloped toward the furnace.
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.
CAUTION
!
PERSONAL INJURY OR PROPERTY DAMAGE
HAZARD
Failure to follow this caution may result in personal injury or property
damage.
Caution should be taken to prevent draining where slippery conditions
may cause personal injuries.
Excessive condensate drainage in open areas may cause saturated soil
conditions which may result in damage to plants and building
foundations.
