Fig. 2 -- Upflow Furnace Right--Side Outlet with External
Condensate Trap and Trap Kit for Vent Above Floor
CARBON MONOXIDE POISONING HAZARD AND
UNIT DAMAGE HAZARD
Failure to follow this warning could result in personal
injury, death and unit damage.
After completing installation, vent pipe must be installed
and fully seated against inducer housing internal stop.
Coupling clamp screw(s) must be tightened to 30 in./--lb of
torque to prevent disassembly of vent from furnace, and to
prevent vent gas and condensate leakage.

WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
Failure to use a properly constructed trap or NOT priming
trap before operating furnace may allow positive pressure
flue gases to enter the structure through drain tube. Flue
gases contain carbon monoxide which is tasteless and
odorless.

WARNING
FOR VENT LOCATED IN UNHEATED
SPACE
Step 1 — Condensate Drain Protection
Freezing condensate in condensate trap and drain line may cause
cracks, and possible water damage may occur (See Table 3). If
freeze protection is required, use condensate freeze protection
accessory or equivalent 3 to 6 watt per ft. at 120v and 40

F (4
_
C) self--regulating, shielded, and waterproof heat tape. See
Installation Instructions supplied with accessory or heat tape
manufacturer’s recommendations.
1. Fold heat tape in half and wrap on itself three times.
2. Locate heat tape between sides of condensate trap back.
3. Use wire ties to secure heat tape in place. Wire can be
positioned in notches of condensate trap sides.
4. Wrap field drain pipe with remaining heat tape,
approximately one wrap per ft.
5. When using field--supplied heat tape, follow heat tape
manufacturer’s instructions for all other installation
guidelines.
Caution should be taken to prevent condensate trap and drain line
from freezing. Ambient temperatures below 32

freeze drain pipe and prohibit draining.
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

trap and drain line have adequate freeze protection. See
Service and Maintenance Instructions for winterizing
procedure.
CAUTION
!
Step 2 — Application
The furnace, A/C, and humidifier drains may be combined and
drained together. The A/C drain must have an external,
field--supplied trap prior to the furnace drain connection. All
drain connections (furnace, A/C, or humidifier) must be
terminated into an open or vented drain as close to the respective
equipment as possible to prevent siphoning of the equipment’s
drain.
Outdoor draining of the furnace is permissible if allowed by local
codes.
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Caution should be taken to prevent draining where slippery
conditions may cause personal injuries.
Excessive condensate draining may cause saturated soil
conditions which may result in damage to plants.
CAUTION
!
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.
