SECTION IV
PRE-INSTALLATION
UNPACKING
INSPECT SHIPMENT carefully for any signs of damage. If
damage is noted, do not install the product. Contact the
shipper or manufacturer. All equipment is carefully
manufactured, inspected, and packed. Our responsibility
ceases upon delivery of the packaged water heater to the
carrier in good condition.
NOTE: Any claims for damage or shortage in shipment must
be filed immediately against the carrier by the consignee.
This water heater MUST be installed indoors out of the
wind and weather.
IMPORTANT DECISIONS REQUIRED BEFORE
INSTALLATION
SIZING
1. Boiler DOE Heating Capacity – The indirect-fired
water heater will provide the rated performance only if
used in conjunction with a heat source with a DOE
heating capacity (Heat Output) at least as much as
the minimum noted in Table 3. If the heat source has
less capacity, the output of the tank will be reduced.
To determine the approximate reduction in output
from the tank use the following formula:
New Rating = (maximum continuous draw rating) x
Actual Output of Heat Source
Minimum Output of Heat Source
For example, what would the continuous draw rating be
if a 52-gallon indirect-fired water heater were installed
with a heat source having a DOE heating capacity of
85,000 BTU/h?
Answer:
New Rating
= 165 gal/hr x (85,000 BTU/h)/(113,000 BTU/h)
= 165 gal/hr x 0.752 = 124 gal/hr
