Hot Water Performance Data
**Performance based on 200° EWT, 20° T.D., 60° E.A.T. Performance at 10° & 30° T.D. is also shown. For capacities at other conditions, use the correction multipliers in the
tables on page 17.
*Speed controller option is required for reduced ratings.

EXAMPLE:
UNIT SIZE _________________042
Entering Water Temp. _____160°F
Entering Air Temp. ________ 40°F
Water Temperature Drop ____ 10°F
I. CAPACITY @ 20° TD:
A. For 200° EWT, 60° EAT
Read output directly from Table 35 & Table 36,
22,700 BTU/HR (Ref., Std. 042, p. 12).
B. For EWT and/or EAT above or below
Standard
Multiply output from Table 35 & Table 36 by factor from
Table 38.
22,700 x .878 = 19,931 BTU/HR.
II. CAPACITY AT OTHER TD's
A. For TD's from 5 to 60°F
Multiply output obtained in IA. or IB.
(above) by appropriate factor from Table 39
IA - 22,700 x 1.15 = 26,105 BTU/HR.
-OR-
IB - 19,931 x 1.15 = 22,921 BTU/HR.
III. GPM AT OTHER TD's
A. For TD's from 5 to 60°F
Multiply GPM of unit for 20° TD, from Table 35 & Table 36
by appropriate factor from Table 39
2.34 x 2.30 = 5.38 GPM (Applies only
to units with. Std. 200° EWT, 60° EAT.)
For all others calculate using formula -
GPM = BTU/500 x TD
IV. PRESSURE LOSS AT OTHER TD's
A.ForTD's from 5 to 60°F
Multiply P.D. of unit for 20° TD, from Table 35 & Table 36
by appropriate factor from Table 39
.06 x 5.00 = .30 Ft. H
