8.3
Checking the magnesium anode
The magnesium anode is a sacrificial anode, which
is consumed by its use during the operation of the
DHW tank. Check the magnesium anode diameter
annually.
Warranty claims for the DHW tank will not be
accepted if the magnesium anode is not serviced on
an annual basis.
z Check magnesium anode (Fig. 18, Item 1) for decay.
Replace the magnesium anode if the diameter has
become reduced to approx. 1/2" to 3/4".
USER NOTE
Never bring the magnesium anode surface
into contact with oil or grease. Keep
everything clean.

ground wire eyelet (Fig. 18, Item 8).
z Remove M8 nut (Fig. 18, Item 7).
z Remove the manual access cover (Fig. 18, Item 3)
from the magnesiumanode (Fig. 18, Item 1).
