24.Fasten the capillary tube(s) by squeezing the retaining clip together, then tighten the screw.

25.Feed the two brown wires through the top hole on the left side until the conduit elbow is against the jacket.

26.Fasten the conduit by sliding the retaining nut over the two brown wires (inside the control compartment) then screwing it down finger-tight on the conduit elbow.

27.Straighten the capillary tubing and fasten it to the side of the heater under the channel. Use the self- tapping screws to fasten the channel to the jacket.

28.Feed the two white wires into the control compartment. Attach one wire to the terminal in the manual reset hi-limit switch. If one is not installed, attach it to terminal No. 1. Connect the other wire to the red wire attached to the fuse holder.

29.Attach the two brown wires to terminals No. 5 and 6 on the terminal strip. Keep all wiring away from surfaces that will get hot during heater operation.

30.Replace the gap closures and tighten the screws securely.

31.Replace the three grommets and the cap.

32.Reinstall the drain plug and drain valves.

33.Slip the flue collector assembly back down inside the enclosure.

34.Carefully slip a hand inside to make sure there are no gaps between the heat exchanger and the flue collector.

35.Check to make sure the wiring is not pinched against sharp edges, or resting on the collector assembly.

36.Replace the two flue collector holddown clamps.

37.Replace the top assembly and fasten it with the hex-head screws.

38.Replace the front cover.

39.Reinstall the vent cap or drafthood if one was removed.

40.On indoor installations (sizes 175-250), insert the draft hood switch plug into the receptacle on the left side of the heater.

2.6.2 Water Chemistry

Bradford White equipment is designed to be used in a variety of water conditions. With the proper pump, the water velocity in the heat exchanger tubes is kept high enough to prevent scaling from hard water, yet low enough to avoid erosion by soft water.

NOTE: It is possible to have hard and soft water in the same city. Check with the local water companies.

If an installer sees damage to any water handling equipment at the installation site, it should be repaired as soon as possible to help reduce maintenance costs. If there is erosion, resize the pump to reduce water velocity before the tube ruptures. If scaling is bad, set up a heat exchanger tube-cleaning maintenance schedule to prevent heat exchanger tube cracking and wear. Not fixing the condition will mean serious damage to the heater and the water system.

NOTES:

In areas where the water supply is soft or corrosive, the heater must have cupronickel tubes in the heat exchanger.

Bradford White does not warrant heat exchangers damaged by scaling, corrosion, or erosion.

2.6.3 Freeze Protection

Although Copper Brute heaters are design certified for outdoor installations, such installations are not recommended in areas subject to freezing temperatures unless proper precautions are taken. Consult the local factory representative or Bradford White for additional information.

2.6.4 Water Hardness

Consider the water hardness when selecting a pump for the heater (see Table 3). Hard water needs a pump which can provide high flow to prevent scaling, while soft water needs low flow to prevent erosion.

2.6.5 Pump Requirements

The Copper Brute heater has a factory installed pump which is for heater-to-tank circulation only. Pump performance is shown in Table 4.

The pump that is mounted on the heater is sized for the heat exchanger and 30 feet (9.1m) of 1-1/2" pipe, including six (6) 90° elbows. If more piping is needed, contact Bradford White for options.

The water temperature entering the Copper Brute must be at least 110°F (43°C).

Figures 20, 21 and 22 show typical piping arrangements. For assistance with other piping methods, contact Bradford White.
