Pre-‐installation Considerations
Inspect shipment carefully for signs of damage. All equipment is carefully inspected and packed.
Heat-‐Flo’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:
Choose the water heater model based on the expected water usage for the given site.
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.
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 cannot be avoided, a suitable drain pan must be installed
under the water heater, and the drain pan must be connected to a drain. The drain pan depth
must be suitable for draining and collecting water. The piping to drain must be at least 3/4”
diameter and be pitched for proper drainage.
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
1”
Front
1”
Top
6”
The minimum clearances for service are:
Bottom
0”
Left, Right, and Rear Sides
3”
Front
30”
Top
6”
