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. Tank sizing.
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 and other references.
2. Locating the water heater.
The water heater should be located in an area where water leakage from the tank or connections will not result in damage
to areas adjacent to the water heater or to lower floors of the structure. When such a location can not be avoided, a
suitable drain pan must be installed under the water heater, and the drain pan must be connected to a drain.
The water heater should be installed as close to the boiler as is practical for easy access for service. The unit is designed
for installation on combustible flooring and in alcoves, closets, etc.
The minimum clearances from combustible surfaces are:
Bottom -------------------------------- 0”
Left, right, and rear sides ---------- 0.5”
Front -------------------------------- 0.5”
Top ------------------------------------ 6”
The minimum clearances for service are:
Bottom -------------------------------- 0”
Left, right, and rear sides ------------ 3”
Front ----------------------------------- 6”
Top ------------------------------------ 6”
