8.8 CONDENSATE DRAIN TRAP
All Benchmark boilers contain a condensate trap (P/N 24441), located external to the unit,
attached to the exhaust manifold’s drain at the rear of the unit.
This trap must be inspected for leaks and blockages, cleaned to ensure that the float is free to
move, and condensate flows normally, and the O-Ring (P/N 84017 included in all 24 Month
Maintenance Kits) replaced if it is worn or damaged. In addition, you must ensure the vent
(under the removable cover) is free and clear of obstructions.

If your system includes a condensate neutralizer, the active ingredient must be replaced
periodically.
