NOTE:Allgasketsandsealsmustbein place for sealed combus-

tion applications.

Remove the 90 ° elbow and vent fitting from the combustion blow- er by loosening the clamps on the vent fitting. Connect the 90 ° el-

bow to the combustion blower using the rubber coupling and cla raps. Note for proper alignment of the vent pipe through the fur- nace, the 90 ° elbow must be installed with the "HORIZONTAL" lettering on the 90 °elbow facing out. Connect the vent fitting to the end of the 90 ° elbow using the clamp.

NOTE: The 90 ° elbow is approved for use inside the furnace ONLY.

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 at- tach the PVC vent extension pipe to the vent fitting with the clamp.

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 pres- sure switch hose to the lower stub on the plastic transition box. Ensure that the hose is routed above the stub on the transition box sothat condensate does not collect in the hose. NOTE: Failure to correctly install the pressure switch hose to the transition can ad- versely affect the safety control operation.

Connect the 3/4" OD rubber hose with the 90 ° bend to the large drain stub on the condensate trap and secure with a 3/4" clamp.

Route the hose to the drain stub on the bottom of the plastic tran- sition box. Cut off excess hose and discard. Connect the hose to

the drain stub on the transition and secure with a 3/4" clamp. 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 smaller 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.
