Ensure that the vent fitting is securely attached to the combustion blower using the rubber coupling and clamps. 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 attach the PVC vent extension pipe to the vent fitting with the cla rap. 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 secure the blower to the transition approximately 1/2". 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 prevent stripping out of the plastic mounting holes. NOTE: 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. 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 attach the PVC vent extension pipe to the vent fitting with the cla rap. Remove the pressure switch hose from the upper stub on the plastic transition box. Relocate the plastic caps on the stubs of the plastic transition box from the lower stubs to the upper stubs and secure tightly with the clamps. Route the pressure switch hose to the lower stub on the plastic transition box. Cut off excess hose and discard. Connect the pressure switch hose to the lower stub on the plastic transition box. NOTE: Failure to correctly install the pressure switch hose to the transition box can adversely affect the safety control operation. Connect the 3/4" OD rubber hose with the 90 ° bend to the drain stub on 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...
