2.8 CONDENSATE DRAIN and 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 is located on the exhaust manifold (Figure 2-8) at the rear of the unit.
This drain port must be connected to the condensate trap (P/N
24441
), which is packed
separately within the unit’s shipping container. The condensate trap outlet connection features a
tapped 3/4” NPT drain port.

2-8: Condensate Drain Connection Location
A sample condensate trap installation is shown in Figure 2-9. However, the actual installation
details for the trap will vary depending on the available clearances, housekeeping pad height
and 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 2-9) must be level with, or lower than the exhaust manifold
condensate drain port.
•
The base of the condensate trap must be supported to ensure that it is level (horizontal).
