•Black water can be an indication of organic contami- nates in the water supply. This can be problematic in areas where the water is obtained from surface or cont- aminated sources. Organic particles can develop bacte- rial growth, causing potential health hazards.

•Contact your water supplier for proper filtration or water conditioning equipment.

•For bacterial problems contact your local health author- ity. See also “Hot Water Odour”.

•A sudden appearance of rust-coloured water may indi- cate that the anode(s) has been depleted. Once deplet- ed, the anode’s inner steel core becomes exposed causing it to corrode and release iron particles into the water. See also “Anode Maintenance”.

Anode Maintenance

A new anode is about 20mm (13/16 in.) to 22mm (7/8 in.) diameter and has a steel wire core approximately 3mm (1/8 in.) diameter in the center. If the anode is less than approx- imately 10mm (3/8 in.) in diameter, or the inner steel core is exposed, the anode(s) should be replaced. Operating a water heater without an actively working anode(s) will void the warranty.

To check/replace the anode:

1.Turn "OFF" the electrical supply to the water heater.

2.Close the cold water supply valve.

3.Open a nearby hot water faucet served by the system to depressurize the system.

4.Connect a hose to the drain valve and drain 22 litres (6 USG.) as directed in “Draining, Flushing and Sediment Removal”.

CAUTION! The water being drained can be extremely

hot! The drain hose should be rated for at least 93°C (200°F). If the drain hose does not have this rating, open the cold water supply valve and a nearby hot water faucet served by the system until the water flow is no longer hot. Close the cold water supply valve and resume.

5.Remove the anode cover, or, on JWF657, Rear and Combination flue models, remove top cover, insulation and flue top cover.

NOTE: The anode(s) has been factory installed using a power tool. It may be necessary for a second person to sta- bilize the heater. A few sharp blows on the handle of the socket wrench should loosen the anode nut. If an impact wrench (power drive) is available, this is an easier way to remove an anode.

6.Using a 1 1/16" socket (certain models require 1-5/16”) , remove the anode(s) and inspect it. The surface may be rough, full of pits and crevices, but this is normal. If it is less than approximately 10mm (3/8 in.) in diameter, or the inner steel core exposed, the anode(s) should be replaced.

7.Apply Teflon® tape, or sealing compounds approved for use with potable water, to the threads of the anode(s) and install into the tank top.

8.Open the cold water supply valve and open a nearby hot water faucet to purge air from the water tank as directed in “Filling the Water Heater”.

9.Check for leaks. Repair as required, and re-test. 10.Replace the covers and insulation and turn the electrical

supply to the heater “ON”.

Cleaning Instructions, Flue Passages Of The JWF657 Heater

Refer to Figure 13 for components of the heater.

1.Remove the casing top and lift if off completely. It is nec- essary to disconnect the hot and cold water lines and move them out of the way. Do not remove the nipples from the tank.

2.Lift off the flue collector. The flue collector has a lip on the outer edge which will allow a hook to grab the edge to help lift it up.

3.Remove the flue baffles (4).

4.With a 76mm (3 in.) diameter wire brush, 1.2m (4 ft.) long, remove any soot build-up which may be on the top head or inside the flue collector.

5.Reassemble in reverse order. It may be necessary to replace the gaskets around the nipples to seal them at the flue collector. Replace the insulation and the casing top.

6.Reconnect the plumbing lines.
