II. Pre-installation Considerations
Inspect shipment carefully for signs of damage. All equipment is carefully inspected and packed. ECR’s responsibility
ceases upon delivery of the water heater to the carrier in good condition. Any claims for damage or shortage, must
be filed immediately against the carrier by the consignee. No claims for variances or shortages will be allowed by the
Manufacturer, unless they are presented within sixty days after receipt of the equipment.
Installation must conform to the requirements of the authority having jurisdiction. In the absence of such requirements,
installation must conform to the National Plumbing Code and the National Electrical Code ANSI/NFPA No. 70, current
edition.
IMpORTANT CONSIDERATIONS bEFORE INSTAllATION
1.
Water Heater Sizing.
Choose the water heater model based on the expected water usage for the given site. The average residence with one
shower or more will require a Model 40 or larger. The Model 30 should only be considered for residences with minimal
water demand, or for commercial applications without showers. See tables on pages 20 and 21.
Consult ASHRAE sizing guides and other references.
Factors that increase water demand dramatically include high flow shower heads, hot tubs, and the use of more than one
shower at a time. Increase the tank size if these factors are present. Consult ASHRAE sizing guides or other references.
Dimensions, weights, ratings, and capacities are outlined in Tables 1 and 2.
2.
Boiler Sizing.
The water heater will provide the rated performance only if it is used with a boiler with a heating capacity of at least
as much as the capacity ratings in Table 2. If the boiler has less capacity, the water heating output will be reduced. To
determine performance with other boiler outputs, refer to the expanded capacity tables in the Appendix.
