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 50-
gallon indirect-fired water heater were installed with a heat
source having a DOE heating capacity of 55,000 BTU/h?
Answer:
New Rating
= 98 gal/hr x (55,000 BTU/h)/(65,000 BTU/h)
= 98 gal/hr x 0.846 =
83 gal/hr
