LOCATING THE NEW WATER HEATER

Facts to Consider About the Location

Carefully choose a location for the new water heater. The placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance.

Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed. The water heater must be located:

1.On a level surface. Shim the channel type skid base as necessary if levelling is required.

2.Near a floor drain. The heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the heater or to lower floors of the structure.

When such locations cannot be avoided, a suitable drain pan should be installed under the heater.

The pan should be at least 2 inches deep, have a minimum length and width of at least 2 inches greater than the dimensions of the water heater and should be piped to an adequate drain.

The discharge opening of the relief valve should always be piped to an open drain.

3.Close to the point of major hot water usage and the power supply.

Hot water piping and branch circuit wiring should be as short as possible.

Insulate hot and cold water piping where heat loss and condensation may be a problem.

Heater construction permits installation, maintenance, and service work to be performed through the front and right side openings.

Suggested clearances from adjacent surfaces are 12 inches on top, 30 inches in front and 24 inches on right side for access to the unit.

The heater may be installed on or against combustible surfaces. The left side and back may be placed flush against adjacent surfaces. Be sure to place the cover plates over the rear crating couplings before locating vertical model heaters. The heater may be installed in a confined space if adequate ventilation is provided.

The temperature of the space in which the water heater is installed must not go below 32°F or above 122°F.

INSTALLATION

REQUIRED ABILITY

INSTALLATION AND SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A QUALIFIED AGENCY (PAGE 2) IN THE FIELD INVOLVED. PLUMBING AND ELECTRICAL WORK IS REQUIRED.

general

The installation must conform to these instructions and the local code authority having jurisdiction. Grounding and electrical wiring connected to the water heater must also conform to the National Electrical Code, NFPA 70. This publication is available from The National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

Do NOT test electrical system before heater is filled with water, follow the START UP procedure in the OPERATION section of this manual.

The principal components of the heater are identified in the Features and Components illustrations on pages 6 and 7.

dish washing, cleaning and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/developmentally disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a maximum water temperature at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a MIXING VALVE, should be used at the hot water taps used by these people or at the water heater.

MIXING VALVES for reducing point of use temperature are available. Consult a qualified installer or service agency. Follow all manufac- turer’s Instructions for installation of these valves. Before chang- ing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual, see Page 14.

MIXING VALVE USAGE:

Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing,

Chemical Vapor Corrosion

This water heater shall not be connected to any heating system(s) or component(s) used with a non-potable water heating appliance.

Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.

Water heater corrosion and component failure can be caused by the heating and breakdown of air borne chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioning
