discharge lines must not be manifolded together. Each must be individually run to a suitable
discharge location.
2.9 CONDENSATE DRAIN & PIPING
The Innovation Water Heater is designed to condense water vapor from the flue products.
Therefore, the installation must have provisions for suitable condensate drainage or collection.
The condensate drain port is located on the exhaust manifold at the rear of the unit (Figure 2-6).
This drain port must be connected to the Condensate Trap (P/N
24441
) which is ordered
separately and packed within the unit’s shipping container.
The Condensate Trap inlet and
outlet connections contain tapped 3/4” (1.91 cm) NPT ports.

Figure 2-6. Condensate Drain Connection Location
A sample Condensate Trap installation is shown in Figure 2-7. However, the actual installation
details for the trap will vary depending on the available clearances, housekeeping pad height/
dimensions and other prevailing conditions at the site. The following general guidelines must be
observed to ensure proper condensate drainage:
•
The condensate trap inlet (Figure 2-7) must be level with, or lower than the exhaust
manifold drain port.
•
The base of the condensate trap must be supported to ensure that it is level (horizontal).
•
The trap must be removable for routine maintenance. AERCO recommends that a union
be utilized between the exhaust manifold condensate drain port and the trap inlet port.
While observing the above guidelines, install the condensate trap as follows:
Condensate Trap Installation
1.
Connect the condensate trap inlet to the exhaust manifold drain connection using the
appropriate piping components (nipples, reducers, elbows, etc.) for the heater installation
site
2.
At the condensate trap outlet, install a 3/4” NPT nipple.
3.
Connect a length of 1” (2.54 cm) I.D. polypropylene hose to the trap outlet and secure with
a hose clamp.
4.
Route the hose on the trap outlet to a nearby floor drain.
