Condensate Drain Connection Location
2.6.1 Exhaust Manifold Condensate
Drain
Refer to Figure 2-5, View A – A and install as
follows:
1. Connect a length of 1 inch I.D. hose (part no.
91030) to the drain on the connecting manifold
and secure it in place with a hose clamp.
2. Route the hose to a nearby floor drain.
2.6.2 Connecting Manifold Condensate
Drain
The connecting manifold drain pipe shown in
Figure 2-5, View B – B must be connected to a
separate condensate drain trap external to the
unit. Refer to Figure 2-6 and install the trap as
follows:
NOTE
The condensate trap described in the
following steps can be installed on the
floor behind the unit as shown in Figure 2-
6. There will be sufficient downward slope
from the drain pipe to the trap inlet to
drain the condensate by gravity. Ensure
that the outlet hose from the trap slopes
away (down) from the trap.
1. Position the supplied condensate trap (part no.
24060) on the floor at the rear of the unit.
2. Install 3/4” NPT nipples in the tapped inlet
and outlet of the condensate trap.
3. Attach a length of 1½” I.D. hose (part no.
GM-123352) between the connecting
manifold drain pipe and the inlet side of the
condensate trap (Figure 2-6). Secure both
ends of the hose with clamps.
4. Connect a second length of 1” I.D.
polypropylene hose to the outlet side of the
condensate trap and route it to a nearby
floor drain.
If desired, a Tee fitting may be used to connect
the two drain hoses from the exhaust manifold
and the
outlet side
of the of the condensate trap
connected in
If a floor drain is not available, a condensate pump
can be used to remove the condensate to drain.
The maximum condensate flow rate is 20 GPH.
The condensate drain trap, associated fittings and
drain lines must be removable for routine
maintenance; therefore, DO NOT hard pipe.
