This pipe may only be shortened if an elbow is used to connect the
PVC vent extension tube to field-installed vent pipe. Securely at­
tach the PVC vent extension pipe to the vent fitting with the clamp.
This configuration allows left side venting from the furnace. If right
side venting is required, the combustion blower must be relocated
on the plastic transition box. Loosen the four(4) screws that se-
NOTE: For right side venting, the vent fitting MUST be installed
with the airflow marking arrow pointed toward the vent pipe, with
the drain stub at a 5° to 10° downward slope. (See
Figure 9)
Plug the upper drain stub on the vent fitting with the yellow plastic
cap.
Connect the PVC vent extension pipe to the vent fitting. This pipe
has a built-in channel to assist vent condensate disposal.
Align the arrow on the PVC pipe with the airflow marking arrow on
the vent fitting. See label on the PVC pipe for proper installation.

blower 180° and secure with the four(4) screws. Note that some
combustion blowers have plastic spacers on the mounting legs of
the blower located at the

and
1 2
o'clock positions (blower snout
to the left or right) that are required for proper fit up of the blower to
the transition. Use caution to not over tighten the screws to pre­
vent stripping out of the plastic mounting holes.
For left side mounted condensate trap, connect the ^/

ber hose with the 90° bend to the large drain stub on the conden­
sate trap and secure with a

Route the hose to the drain stub on the bottom of the plastic transi­
tion box. Cut off excess hose and discard. Connect the hose to the
drain stub on the transition and secure with a ^/

Route the hose to the large drain stub on the condensate trap. Cut
off excess hose and discard. Connect the hose to the drain stub
on the condensate trap and secure with a

For left or right side mounted condensate trap, the pressure
tap on the condensate trap MUST be connected to the unused
pressure tap located on the upper right hand corner of the plastic
transition box. Remove the plastic caps from the pressure taps on
the condensate trap and the plastic transition and connect with

Connect the S/g ' OD rubber hose with the 90° bend to the lower
drain stub on the vent fitting and secure with a ®/g" clamp.
Route the hose to the small drain stub on the condensate trap. Cut
off excess hose and discard. Connect the hose to the drain stub
on the trap and secure with a ®/g" clamp.
NOTE: Route hoses to the condensate trap with no kinking or
binding for proper condensate drainage.
