I. Condensate Removal System
NOTE:
Check with your local gas company to determine if
combustion condensate disposal is permitted in your area. In
the state of Massachusetts, condensate must be neutralized
before entering a drain.
This boiler is a high efficiency appliance, and therefore produces
condensate: a by-product of the combustion process. A
condensate collection system with an internal float switch
monitors condensate level to prevent it from backing up into the
combustion system. There is a flexible line that must be piped to
a drain or condensate pump.
Condensate from the boiler is slightly acidic with a pH of 3.2
- 4.5. To avoid long term damage to the drainage system and
to meet local code requirements, Westinghouse recommends
neutralizing condensate with a Condensate Neutralizer Kit (Part
# 7450P-212 for EL-80/110/150/220/299/301, Part # 7350P-611
for EL-399). The neutralizer kit connects to the drain system
and contains limestone chips that neutralize the pH level of the
condensate. The neutralizer kit should be checked annually and
the limestone chips replenished if necessary. When replacing
the limestone chips, take care to ensure chips are no smaller
than ½” to avoid blockage in condensate piping (refer to Figure
26 for piping of the condensate neutralizer.)
