Upflow Installations - (Dual Certified*9MPD, *9MPT &*9MPV)(See Figure 1)
NOTE: DO NOT make connections until the hose routing and
lengths have been determined. Remove the condensate trap and
drain hoses from the furnace and secure the drain hoses to the
drain stubs on the trap with the hose clamps (position the clamps as
shown in Figure 1). Install the condensate trap/hose assembly to
the furnace casing. Hook one side of the "clamp ears" on the drain
stub through the hole in the casing and push the condensate trap
into position. Secure with the two screws. Reconnect the drain
hoses to the stubs on the vent fitting and the plastic transition and
secure with the clamps.
Mount the condensate drain trap in a vertical position to either the
left or right side of the furnace using the two screws and gasket that
are provided. If needed, remove the hole plugs from the furnace
side panel and relocate to the open set of holes in the opposite side
panel.
NOTE: All gaskets and seals must be in place for sealed combus-
tion applications.
Ensure that the vent fitting and the 90 ° street elbow are securely
attached to the combustion blower using the clamps.
Plug the upper drain stub on the vent fitting with the yellow plastic
cap.
Glue the PVC vent extension pipe to the 90 ° street elbow after
checking the fit up. (Follow the procedures outlined in the Joining
Pipe and Fittings section of this manual, page 13.) Disregard the
instruction label on the PVC vent extension pipe. The orientation of
the supplied PVC vent extension pipe is not critical in the vertical
position. The PVC pipe will extend through the top panel about
21/2". Connect the rubber coupling to the end ofthe PVC extension
pipe using the clamp.
NOTE: There will be some misalignment ofthe PVC pipe inside the
furnace. The rubber coupling will straighten outthe misalignment at
the vent pipe connection at the top of the furnace.
For left side venting, remove 90 ° street elbow from the vent fitting
by loosening the clamp on the vent fitting. Securely attach vent fit-
ting to combustion blower.
NOTE: For left 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.
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 of the blow-
er located atthe 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: 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 2)
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.
For left side mounted condensate trap, 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 ofthe 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.
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.
