CAUTION

The heat transfer medium must be water or other non-toxic fluid having a toxicity rating or class of 1, as listed in clinical Toxicology of Commercial Products, 5th edition.

The pressure of the heat transfer medium must be limited to a maximum of 30 psig by an approved safety or relief valve.

NOTICE

This w ater heater has a limited warranty, a copy of w hich is printed on the back of this manual. It is the responsibility of the installing contractor to see that all controls are correctly installed and are operating properly when the installation is complete.

II. Pre-Installation

Inspect shipment carefully for any sign of damage. All equipment is carefully manufactured, inspected and packed. Burnham Corporation's responsibility ceases upon delivery of water heater to the carrier in good condition. Any claim for damage or shortage in shipment must be filed immediately against the carrier by the consignee. No claims for variances or shortages will be allowed by Manufacturer, unless presented within sixty (60) days after receipt of equipment.

Installation must conform to the requirements of the authority having jurisdiction. In the absence of such requirements, installation must conform to National Plumbing Code and National Electrical Code, ANSI/NFPA No. 70, current edition.

present.

Consult Burnham for size recommendations for installation with unusual water demand.

Refer to Table 3 for water heater performance specifications.

2.Boiler DOE Heating Capacity The Alliance™ water heater will provide the rated performance only if used in conjunction with a boiler with a DOE heating capacity 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:

IMPORTANT DECISIONS REQUIRED BEFORE

INSTALLATION:

For example, what would the first hour rating be if a model AL53A were installed with a boiler having a DOE heating capacity of 120,000 BTU/h?

A.Sizing

1.Alliance™ Model - Choose the Alliance™ model based on the expected water usage of the building. The average residence with one shower or more will require a model AL40A or larger. The AL26A should only be considered for residences with minimal water demand or for commercial application where showers are not present.

Factors which dramatically increase water demand include high flow shower heads, whirlpool tubs, and the use of multiple showers at the same time. Upsize the tank size if any of these factors are

Increasing the boiler DOE heating capacity above the values listed in Table 3 will not increase the rating of the water heater.

3.Circulator Sizing - Refer to Table 3 for the minimum flow rate through the water heater coil and the corresponding pressure drop through the coil. Calculate the pressure drop of all straight pipe and fittings on the supply and return of the water heater at the minimum flow rate. Add the piping/ fitting pressure drop to the pressure drop through the water heater coil.
