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 Drain Installation Instructions
1. Connect the condensate trap inlet to the exhaust manifold drain connection using the
appropriate piping components (nipples, reducers, elbows, etc.) for the 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
40 gallons (151 liters) per hour
.
The condensate drain trap, associated fittings and drain line must be removable for routine maintenance.
WARNING!
Use PVC, stainless steel, aluminum or polypropylene for condensate drain piping. DO
NOT
use carbon or copper components.
