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. 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 cla rap.

cure the blower to the transition approximately 112". Rotate the 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 6 and 12 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 3/4" OU rub- ber hose with the 90 ° bend to the large drain stub on the conden- sate trap and secure with a 3/4" clamp.

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 3/4" clamp.

For right side mounted condensate trap, connect the 3/4" OD rub- ber hose with the 90 ° bend to the bottom of the plastic transition box and secure with a 3/4" clamp.

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 3/4" clamp.

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 the 5/16" OD rubber hose. (See Figure 8 and Figure 9)

Connect the 5/8" OD rubber hose with the 90 ° bend to the lower

drain stub on the vent fitting and secure with a 5/8" 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 5/8" clamp.

NOTE: Route hoses to the condensate trap with no kinking or binding for proper condensate drainage.
