Bradford-White Corp MAGNUM Series Commercial Electric Booster manual Important Safety Information

IMPORTANT SAFETY INFORMATION

Read the following important safety information before using this equipment to avoid serious injury or death and to avoid damage to equipment or property.

WARNING

ELECTRIC SHOCK HAZARD:

• This unit must be installed by qualified, trained installers. Installation must conform to all local electrical and plumbing codes. Check with your local plumbing and electrical inspectors for proper procedures and codes.

• Turn power OFF at disconnect switch/circuit breaker and allow unit to cool before performing any maintenance or cleaning.

• Consult a licensed electrical contractor for proper electrical installation conforming to local electrical codes and the National Electrical Code (N.E.C.).

• Unit is not weatherproof. Locate unit indoors where ambient air temperature is a minimum of 70°F (21°C).

• Do not place aftermarket covers on or over booster water heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock.

• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.

• Use only Genuine Bradford White Replacement Parts when service is required. Failure to use Genuine Bradford White Replacement Parts will void all warranties and may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn. Genuine Bradford White Replacement Parts are specified to operate safely in the environments in which they are used. Some aftermarket or generic replacement parts do not have the characteristics that will allow them to operate safely in Bradford White equipment.

EXPLOSION HAZARD: Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.

Bradford White has always endorsed the use of safety equipment when using an booster water heater or storage- type water heater. Bradford White booster water heaters are shipped with a temperature/pressure relief valve at no extra charge. This valve must be installed into the marked opening provided in the tank. Valves supplied with this booster water heater are designed for high temperature commercial operation. Do not substitute these valves with valves designed for domestic water heaters.

Temperature/pressure protective equipment should not be less than a combination temperature/pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of this equipment and meets the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-1979. The temperature/pressure relief valve must be marked with a minimum set pressure not to exceed the marked hydrostatic test pressure of the booster heater as noted on the unit specifications.

Do not connect an expansion tank of any type to booster water heater lines.

Form No. EBOOSTERBWM-1009 1

WARNING

FOR INSTALLING COMBINATION TEMPERATURE/ PRESSURE RELIEF VALVES IN ACCORDANCE WITH AMERICAN NATIONAL STD. Z21.22-1979. Combination temperature/pressure relief valves with extension thermostats must be installed so that the temperature- sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed either in the hot outlet service line or directly in a tank tapping. Combination temperature/pressure relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from the flue gas heat or other ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9144 mm), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

Inspect combination temperature/pressure relief valve at least once every two to four years, depending on local water conditions. Contact a licensed plumber or qualified service technician for inspection. Replace valve, if necessary. DO NOT attempt to self-inspect valve.

Use only plumbing material suitable for a minimum water temperature of 200°F (93°C). Materials used must meet National Sanitation Foundation (NSF) specifications and all local plumbing codes and regulations.

Install booster water heater in horizontal position with base parallel to the floor and inlet connection at the lowest point. If installing with legs, mount on floor. If installing with slide brackets, mount under dish table. DO NOT mount on walls or in ceiling. Unit must be accessible for service. Improper installation could create an unsafe condition.

Valves supplied with this booster water heater are designed for high temperature commercial operation. Do not substitute these valves with valves designed for domestic water heaters.
