NOTE: All gaskets and seals must be in place for sealed combus-
tion applications.
For both right and left side vent, remove the 90 ° street elbow
from the vent fitting by loosening the clamp on the vent fitting.
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 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 secure
the blower to the transition approximately1/2 ". Rotate the blower
180 ° and secure with the four(4) screws. Note that some combus-
tion blowers have plastic spacers on the mounting legs ofthe blow-
er 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 transi-
tion. 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 pips
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 plas-
tic 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.
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 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 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.
For left side or right side mounted condensate trap, the pres-
sure tap on the condensate trap MUST be connected to the unused
pressure tap located on the top of the plastic transition box. Re-
move the plastic caps from the pressure tap on the condensate trap
and the plastic transition and connect the 5/16" OD rubber hose.
(See Figure 5)
NOTE: Route hoses to the condensate trap with no kinking or bind-
ing for proper condensate drainage.
