11. Plastic Drain Pan Application
D O NOT USE THE COIL PAN SHIPPED WITH THE UNIT ON OIL FURNACES
OR ANY APPLICATION WHERE THE TEMPERATURE OF THE DRAIN PAN MAY
EXCEED 300°F. A HIGH TEMPERATURE DRAIN PAN SUCH AS KITS HTP-A,
-B, -C
AND -D FOR NORMAL CABINET WIDTHS OF 14, 17.5, 21 AND
24.5
INCHES , RESPECTIVELY , SHOULD BE USED FOR APPLICATIONS WHERE
THE TEMPERATURE EXCEEDS 300°F AND BELOW 450°F. A FIELD
FABRICATED METAL DRAIN PAN CAN ALSO BE USED FOR APPLICATIONS
WHERE TEMPERATURE EXCEEDS 300°F.
F
AILURE TO FOLLOW THIS WARNING MAY RESULT IN PROPERTY DAMAGE
AND / OR PERSONAL INJURY .
If the uncased coil is to be installed on top of a gas furnace, allow
enough space between the top to the furnace and the bottom of
the plastic coil drain pan to have a free flow of air.
A minimum of 2.0" distance from the top of the furnace and the
bottom of the coil pan is required.
NOTE: The coil must be installed with the line set and drain open-
ings to the front of the furnace.

NOTE: Water coming from the secondary line means the coil pri-
mary drain is plugged and needs immediate attention.
Install a trap in the drain line below the bottom of the drain pan
(Figure 5). If using a copper drain line, solder a short piece of
pipe, minimum 6” length, to the connector before installing a drain
fitting.
DO NOT over torque the 3/4” copper connector to the plastic drain
connection. Using a wet rag or heatsink material on the short
piece to protect the plastic drain pan, complete the drain line
installation. Use Figure 6 as a template for typical drain pipe
routing. This figure shows how to avoid interference with vent
piping.

DO NOT TERMINATE THE RETURN DUCTWORK IN AN AREA
THAT CAN INTRODUCE TOXIC OR OBJECTIONABLE FUMES/
ODORS INTO THE DUCTWORK.
13. Sealing Along The Panel Gap
IMPORTANT NOTE: To prevent cabinet sweating and
airflow leak, apply field provided insulation tape along
all joining surfaces between the coil, gas furnace, duct
work and panels. See Figure 7.
