COPPER BRUTE II (500 - 2000) USER'S MANUAL

SECTION 1 Caring For Your

Copper Brute ll

Your Copper Brute ll will require very little

Maintenance. However, as with any ne appliance

there are certain steps that should be taken to ensure

continuing optimum performance.

1.A General Care

Keep the area around the Copper Brute ll clean

and free from combustible materials, gasoline and

other ammable liquids and vapors.

The Copper Brute ll must be completely isolated

and protected from any source of corrosive chemical

fumes such as trichlorethylene, perchlorethylene,

chlorine, etc.

Keep grille openings on the boiler free for proper

ventilation of interior components.

Do not obstruct or block a free ow of air to the

boiler to ensure proper ventilation.

If desired, clean the jacket surfaces with a damp

cloth and mild detergent. Do not use ammable

cleaning materials.

If sidewall vented, keep the vent terminal clear

of obstructions — do not pile snow against the vent

terminal. Clean the air lter(s) often, and then develop

an appropriate maintenance schedule.

1.B Annual Inspection of Flue and Vents

Visually inspect the vent pipe once a year. Should

any deterioration exist, have the affected parts replaced

by a qualied service person.

1.C In the Event of a Power Failure

The Copper Brute ll can not be operated during

an electrical power outage. If there is an extended

power outage with danger from freezing, then the

Copper Brute ll (and all other water systems) should

be drained completely. When draining the boiler, turn

off main electrical disconnect switch. When placing

back in service, refer to start-up instructions in the

Installation and Operation Manual for lling and

purging. Draining and lling shall only be done by a

qualied service person.

1.D Full Service Every Three (3) Years

In addition to the annual visual inspections, a

qualied service agency should conduct a detailed

inspection of all ue product carrying areas of the

boiler and its venting system.

WARNING

Do not use this boiler if any part has been

under water. Immediately call a qualied

service technician to inspect the boiler and to

replace any part of the control system and any

gas control which has been under water.

WARNING

Should overheating occur or the gas supply

fail to shut off, do not turn off or disconnect the

electrical supply to the pump. Instead, shut

off the gas supply at a location external to the

boiler.

FOR SERVICE

Contact your installing contractor, gas utility,

Bradford White dealer, or call Bradford White

for the nearest authorized representative in

your area.
