7.9 CONDENSATE DRAIN TRAP
The Benchmark Boiler contains a condensate trap as shown in Chapter 2, Figure 2-7. The trap is
located external to the unit and attached to the drain pipe from the exhaust manifold. This trap
should be inspected and cleaned in accordance with the maintenance schedule shown in Table
7-1 to ensure proper operation. To inspect and clean the trap, proceed as follows:
Condensate Drain Trap Maintenance Procedure
1. Disconnect the external condensate trap from the exhaust manifold by loosening the
thumb screw on the trap inlet shown in Figure 7-10.
2. Remove the connection on the outlet side of the condensate trap.
3. Loosen the four (4) thumbscrews securing the cover on the condensate trap. Remove the
cover.
4. Remove the float and float guide from the condensate trap.
5. Remove the O-ring from the trap. AERCO recommends that this O-ring be replaced
annually.
6. Thoroughly clean the trap and float. Also inspect the drain piping for blockage. If the trap
cannot be thoroughly cleaned, replace the trap.
7. After the above items have been inspected and thoroughly cleaned, replace the O-ring
(84017) with a new part.
8. Reassemble all piping and hose connections to the condensate trap outlet. Reconnect trap
to exhaust manifold drain by tightening the thumbscrew on the trap inlet.
