When the system requires water for heating at

temperatures higher than required for other uses,

an anti-scald mixing or tempering valve shall be

installed to temper the water for those uses in order

to reduce scald hazard potential.

4B.5 Freeze Protection – Water Heater

Although Copper Brute II water heaters are

design-certied for outdoor installations, such

installations are not recommended in areas subject to

freezing temperatures, unless proper precautions are

taken.

Power outage, interruption of gas supply, failure

of system components, activation of safety devices,

etc., may prevent a heater from ring. Any time a

heater is subjected to freezing conditions, and the

heater is not able to re, and/or the water is not

able to circulate, there is a risk of freezing in the

heater or in the pipes in the system. When water

freezes, it expands. This can result in bursting of pipes

in the system, or damage to the heater, which could

result in leaking or ooding conditions.

Contact the local factory representative or

Bradford White for additional information.
