chips will neutralize slightly acidic condensate (p/n 7450P-212
available from Westinghouse). Follow all the installation instructions
included with the neutralizer. If a neutralizer is installed (2), periodic
replacement of the limestone (or neutralizing agent) will be required.
The rate of depletion of the limestone varies with usage of the water
heater. During the first year of water heater operation, check the
neutralizer every few months for depletion.
7. Route the drain line to a nearby floor drain (1), laundry tub (3), or
condensate pump (4). If the heater condensate outlet is lower than
the drain, you must use a condensate removal pump (kit p/n 554200
available from Westinghouse).
NOTE: If a nearby laundry tub is used as a disposal for waste water
from the washing machine, draining the condensate into this tub
allows the soapy water discharge to neutralize the acidic condensate.
8. An error will appear on the water heater display if condensate line is
blocked. The water heater will not operate with a blocked condensate
line. It is extremely important to have this condition repaired by a
qualified service technician.
The condensate trap must be filled and unobstructed to allow
unrestricted flow of condensate. The condensate should not be
subject to freezing conditions. If the condensate is subjected to
freezing or obstruction, it will result in potential water damage to
the water heater and surrounding area, and possible personal injury.
Such damages are not covered under warranty.
The condensate trap must be filled with water prior to using the
water heater. Pour water into the exhaust adaptor until it flows out
of the condensate drain before using the water heater to fill the trap.
See Figure 28.

The end of the condensate drain pipe must not be submerged
in water or blocked in any way. Take measures to prevent the
condensate drain lines from freezing (insulation, heat tape, etc.)
