9.1.1 Condensate Neutralization Tube (optional)
If a condensate ne u tralization t u be is specified to be
u sed w ith the heating system, follo w the steps belo w
to choose the proper condensate ne u tralization t u be.
See Page 37, Figure 17 .
Step 1: Condensate flow ( g al/h) per 100,000 Btu/h
installed
Yo u w ill need to kno w the tailpipe length per flo w u nit
and the total inp u t (Bt u /h) on the heating system.
Please refer to the follo w ing chart to determine the
condensate flo w (gal/h) per 100,000 Bt u /h installed:
Step 2: Total condensate
Determine the total condensate (gal/h) u sing the
follo w calc u lation:
Total condensate ( g al/h) = Total Input (Btu/h) /
100,000 (Btu/h) x condensate flow ( g al/h)
Step 3: Choose the condensate neutralization
tube
Choose the condensate ne u tralization t u be w hich is
closest to and higher than the calc u lated gal/h v al u e.
Example:
CORAYVAC ® system has a total inp u t of 600,000
Bt u /h. The radiant t u be length and tailpipe are set- u p
according to the RECOMMENDED specifications.
Step 1: Condensate flow ( g al/h) per 100,000
Btu/h installed
Select 0.3 from the Condensate flo w chart.
Step 2: Total condensate
M u ltiply the total inp u t Bt u /h / 100,000 by the
condensate flo w (gal/h) per 100,000 (Bt u /h)
(600,000/100,000) x 0.3 = 1.8 (gal/h)
Step 3: Choose the condensate neutralization
tube
Choose the condensate ne u tralization t u be w hich is
closest to and higher than the calc u lated gal/h v al u e.
For this example, the total condensate is 1.8 (gal/h),
the condensate ne
u tralization t u be w hich is closest
to and higher than the calc u lated gal/h v al u e is P/N
01327002.
NOTE: Condensate ne u tralization t u bes m u st be
replaced yearly (e v ery 2000 operating ho u rs) or
check condensate w ater pH le v el. If it is belo w pH 6,
replace t u be.
