and their frequencies, including any not listed in the following paragraphs.

The purpose of the magnesium anode is to reduce the damaging effects of aggressive water on the wa- ter heater. Aggressive water will cause the anode to erode.

The anode must be inspected at least annually to de- termine whether a new anode should be installed.

Severe or rapid deterioration of the anode indicates very aggressive water. If this occurs, have the water tested to verify whether it is within the limits given under “Operating restrictions,” page 3.

Failure to inspect the anode regularly and replace if necessary could result in damage to the water heater, causing possible severe personal injury, death or substantial property damage.

Inspect anode and water heater interior

1.Close domestic water isolation valves.

2.Drain the water heater completely and allow it to cool off.

3.Remove the inspection hatch cover (Figure 24, page 39, item 8).

a.The temperature control bulb will have to be pulled out of the immersion well, located in the inspection plate.

4.After the water heater has drained and cooled, remove the inspec- tion plate (Figure 22, page 26, item 2).

There will be some water remaining in the bottom of the water heater. This can be siphoned off or removed with a wet/dry vacuum.

a.Partially unscrew the M8 hex nut (Figure 22, page 26, item 5) while holding the bracket (Figure 22, page 26, item 6). DO NOT completely remove the nut.

b.Hold and turn the bracket 90 degrees, being careful not to drop the inspection plate inside the tank.

c.Remove the inspection plate.

5.Use a work light or flash light to inspect the interior of the tank.

6.Use a plastic scraper if needed to remove any accumulation on the coil. DO NOT use abrasives or metallic objects.

7.Remove as much sediment as possible through the inspection opening.

8.Rinse the bottom and remove remainder with a wet/dry shop vacuum.

9.Remove the magnesium anode cover and anode (Figure 24, page 39, items 10 and 1).

10.Inspect the anode and replace if needed with part list in (Fig- ure 24, page 39). See WARNING above.

11.Replace the inspection plate gasket if necessary. Then re-install the inspection plate. Align the gasket carefully. DO NOT over-tighten the bolt. This could damage or extrude the gasket, or distort the plate.

12.Re-install the access cover hatch and tighten the four M8 Phillips-head screws. Do not over-tighten the screws.

13.Refill the water heater and restore to operation.

14.Verify operation of boiler and water heater.

Drain the water heater if necessary during shutdown periods

1.Drain the water heater if it will be shut off and exposed to freezing temperatures. Freezing water will expand and may damage water heater.

a.If boiler water contains sufficient antifreeze, then only the domestic water needs to be drained.

b.If boiler water does not contain sufficient antifreeze, then the boiler water and the domestic water must be drained.
