for horizontal installation.
Remove the existing condensate
trap with the unit in the upright
position.
2. Remove the burner compartment
door from the unit.
3. Remove the two screws from the
right side of the furnace jacket
which support the trap mounting
bracket . Remove the two
plastic plugs on either side of the
trap outlet hole and discard.
4. Remove the (L-shaped) clear
vinyl drain tube from the top of
the existing trap .
Do not disconnect the short end
from the furnace collector box.

from the existing trap
exhaust transition . Discard this
tube. Retain the clamps for future
use. Additional clamps are
provided in the parts bag if any
clamps are damaged during

from inside the jacket. Use two
screws provided. Screw down
into the two "ears" molded into
either side of the trap. Snug the
trap assembly against the
furnace jacket compressing the
gasket slightly to eliminate any
air leaks. Do not overtighten!
