tube.
Upflow Specific Steps – Offset Installation
1. Trap Offset Adapter Accessory Kit (purchased separately) is
required. Instead of installing the trap to the adapter plate, screw the
trap offset adapter to the adapter plate (see
2. Screw the trap to the trap offset adapter (see
3. Screw the trap adapter plate to the casing using the supplied sheet
metal screw (see
Fig.
16).
4. Remove factory-installed collector box cap. Run tube from port on
upper left of the collector box to the relief port on the trap adapter
(Fig 19). If the tube is too long, cut any extra length from the tube.
Horizontal Specific Steps
1. Accessory Horizontal Installation Kit (trap grommet) is required for
all direct-vent horizontal installations (only). The kit contains a
rubber casing grommet designed to seal between the furnace casing
and the condensate trap. (see
Fig. 20 – Horizontal Right - Trap Assembly Aid
2. Install the grommet in the casing when required for direct-vent
horizontal applications.
3. Allow for 6-3/8" (162 mm) of clearance underneath the furnace for
the condensate trap and drain line. It is recommended to leave an
additional 1" clearance under the trap for service (see
4. Remove appropriate collector box drain plug (see
5. Attach trap to collector box using provided machine screw
(Fig.
20).
6. For horizontal right side down:
a. Remove factory-installed collector box cap.
b. Remove the factory-installed cap from the relief port on the trap
and run tube from port on the collector box corner opposite of the
trap to the relief port on the trap (see
long, cut any extra length from the tube. In the installed position,
the transducer tubing should be in the lower pressure port and the
relief tubing should be in the higher port.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

(Note: Drain line can be run horizontally or vertically)
NOTE: Field Supplied Drain can be routed horizontally from the trap,
allow at least 1/4-in. per foot of slope down.
Extra water in transducer pressure tubing may inhibit furnace operation
because of incorrect pressure readings.

7. For horizontal left side down:
a. Remove factory-installed collector box cap.
b. Remove the factory-installed cap from the relief port on the trap
and run tube from port on the collector box corner opposite of the
trap to the relief port on the trap (see
removing the transducer pressure tubing from the
factory-installed position. If the tube is too long, cut any extra
length from the tube.
c. Install transducer pressure tubing on the collector box port
closest to the trap where the factory-installed collector box cap
was installed (see
length ensuring no traps of loops for extra water collections. In
the installed position, the transducer tubing should be in the
lower pressure port and the relief tubing should be in the higher
port.
It is permissible to run the trap up to 5 ft. away from the furnace to an
area with the required trap clearance provided the following steps and
conditions are followed.
