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 listed on rating plate. All equipment is carefully
manufactured, inspected, and packed. Our responsibility ceases
upon delivery of the packaged 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.
IMPORTANT DECISIONS REQUIRED
BEFORE INSTALLATION
SIZING
1. Boiler DOE Heating Capacity – The Single-wall
Indirect water heater will provide the rated performance
only if used in conjunction with a boiler with a DOE
heating capacity (Boiler Output) at least as much as the
minimum noted in Table 3. If the boiler 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 first hour rating) x
Actual Boiler Output Capacity
Minimum Boiler Output Capacity
For example, what would the 140°F first hour rating be
if model SW-2-50-L was installed with a boiler having a
DOE heating capacity of 180,000 BTU/h?
