Condensate Disposal
The condensate drain must be  lled and unobstructed to allow  ow of condensate. The condensate should not
be subjected to conditions where freezing could occur. If the condensate is subjected to freezing or obstruction, it
can leak, resulting in potential water damage to the unit and surrounding area.
The drain line material must be a material approved by the authority having jurisdiction. In absence of such
authority, PVC and CPVC piping must comply with ASTM D1785 or D2846. This pipe must be connected to the
port at the side panel. The end of the pipe should drain to a laundry tub or to a
 oor drain.
Over time, blockage of the trap by debris may occur; when the condensate cannot be released, the unit will go into
error and will shut down. When this occurs, the trap must be cleaned.
CLEANING OUT THE TRAP
The condensate trap must be  lled with water prior to using the water heater.
Pour water down the exhaust collar until water visibly
 ows out of condensate drain before  rst use.
Eternal water heater will typically produce a condensate that is considered slightly acidic with a Ph content of
approximately 3-4. Install a neutralizing
 lter if required by authority having jurisdiction (See  gure 2).
Direct to drain from the unit.
Drain through neutralizer from the unit.
Drain to laundry tub from the unit, in this case the unit must be above the height of the laundry tub.
When installing a condensate pump, ensure the pump is approved for use with condensing appliance.
The pump should be equipped with an over
 ow switch to prevent property damage from potential condensate
spillage.
