Figure 2-5: Condensate Drain Connection Location
A sample condensate trap installation is shown in Figure 2-6. 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 2-6) 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 boiler installation
site.
2. At the condensate trap outlet, install a 3/4" NPT nipple.
3. Connect a length of 1" 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 an
appropriate drain location. The maximum condensate flow rate is 30 GPH. The condensate drain trap,
associated fittings and drain line must be removable for routine maintenance.
Use PVC, stainless steel, aluminum or polypropylene for
condensate drain piping (Figure 2-6). DO NOT use carbon or
copper components.
