2.9 CONDENSATE DRAIN & PIPING
The Innovation Hot Water Boiler 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 packed within
the unit's shipping container. The Condensate Trap inlet and outlet connections contain tapped
3/4" (1.91 cm) NPT ports.

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:
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.
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 10 Gallons (37.85 L) per hour. The
condensate drain trap, associated fittings and drain line must be removable for routine
maintenance.
