2.6 CONDENSATE DRAIN AND PIPING
The Benchmark 2.0LN 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 pipe located on the exhaust manifold (Figure 2-4) must be connected to a
condensate trap which is packed separately within the unit’s shipping container.
The procedure to install and connect the condensate drain is provided in paragraph 2.6.1.
