or component(s) previously used with a non-potable
water heating appliance.
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 Brute Deluxe water heaters are design-
certified 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 firing. Any time a
heater is subjected to freezing conditions, and the
heater is not able to fire, 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 flooding conditions.
Contact the local factory representative or
Bradford White for additional information.

Notes:
1. S = soft water (1 to 7.5 grains hardness)
2. N = normal water (7.6 to 17 grains hardness)
3. H = hard water (more than 17 grains hardness)
4. gpm = gallons per minute, lpm = liters per minute, ft = head loss in feet, m = head loss in meters
5. Head loss is for heater's heat exchanger only
