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 EQUIRED

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?
