Bradford-White Corp ULTRA HIGH EFFICIENCY COMMERCIAL GAS WATER HEATER Manual De Usuario

The usage of water softening equipment greatly reduces the hardness of the water. However, this equipment does not
always remove all of the hardness (lime). For this reason it is recommended that a regular schedule of deliming be
maintained.
The depth of the buildup should be measured periodically. Water heaters will have about 3 inches of lime buildup when
the level of lime has reached the bottom of the cleanout opening or about 1 inch of lime buildup if it has reached the drain
valve opening. A schedule for deliming should be set up, based on the amount of time it would take for a 1/2 inch buildup
of lime.
Example 1: Initial inspection shows ½ an inch of lime accumulation. Therefore, the water heater can be delimed once a
year.

To remove sediment and lime scale:
1. Drain the heater. Refer to DRAINING THE WATER instructions in this section.
2. Remove outer cover plate from lower side of water heater jacket.
3. Remove cover and gasket from cleanout opening.
4. Remove lime, scale or sediment using care not to damage the glass-lining.

ANODE INSPECTION AND REPLACEMENT
This water heater is equipped with multiple sacrificial anodes. Anodes protect the glass-lined tank from corrosion by
sacrificing themselves through electrolysis. When the anode material is consumed, there is no more protection and
corrosion of the tank accelerates.
Inspection of the anode every 6 months allows you to identify the rate of anode degradation. The anode should be
replaced when its diameter is 3/8 of an inch, or annually whichever is first. Aggressive, very hot and softened water
causes rapid consumption of the anode requiring frequent inspections. The replacement anodes rods are available from
your Bradford White distributor.
To inspect or replace an anode:
The anodes on this water heater are easily accessible from the top of the water heater making replacement simple and
quick. Use the following procedure to remove and inspect the anodes.
