2.7 CONDENSATE DRAIN & PIPING
The Benchmark 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 located on the exhaust manifold (Figure 2-5) must be connected to
the condensate trap (part no. 24060) which is packed separately within the unit’s shipping
container. The condensate trap inlet and outlet connections contain tapped 3/4” NPT ports.
Figure2-5: 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.
