9.5 Condensate Trap and Condensate Tee
The condensate trap assembly (optional) (P/N
01327001), should be installed on the inlet side of the
EP-200 Series pump assembly, See Page 18, Figure
17.
It is possible to eliminate the condensate trap
assembly on the pump if the one-inch threaded hole
is plugged. This arrangement will permit drainage of
condensate through the pump and outside via
horizontal (pitched) discharge line.
The condensate trap assembly in the discharge line
can be eliminated if the discharge line is horizontal
through the wall and pitched down at least one inch
per foot. A condensate trap on the discharge side is
required if there is a vertical rise in the discharge line.
9.5.1 Condensate Neutralization Tube (optional)
If a condensate neutralization tube is specified to be
used with the heating system, follow the steps below
to choose the proper condensate neutralization tube.
See Page 20, Figure 19.
Step 1: Condensate flow (gal/h) per 100,000 Btu/h
installed
Yo u will need to know the tailpipe length per flow unit
and the total input (Btu/h) on the heating system.
Please refer to the following chart to determine the
condensate flow (gal/h) per 100,000 Btu/h installed:
Step 2: Total condensate
Determine the total condensate (gal/h) using the
follow calculation:
Total condensate (gal/h) = Total Input (Btu/h) /
100,000 (Btu/h) x condensate flow (gal/h)
Step 3: Choose the condensate neutralization
tube
Choose the condensate neutralization tube which is
closest to and higher than the calculated gal/h value.
Example:
CORAYVAC
®
system has a total input of 600,000
Btu/h. The radiant tube length and tailpipe are set-up
according to the RECOMMENDED specifications.
Step 1: Condensate flow (gal/h) per 100,000
Btu/h installed
Select 0.3 from the Condensate flow chart.
Step 2: Total condensate
Multiply the total input Btu/h / 100,000 by the
condensate flow (gal/h) per 100,000 (Btu/h)
(600,000/100,000) x 0.3 = 1.8 (gal/h)
