WATER ODOR/SACRIFICIAL ANODE
Your storage tank has been equipped with one magnesium
anode that will slowly deplete while protecting the glass-lined
tank thus prolonging its life. Certain water conditions may
cause a reaction between the anode and the water. The most
common complaint associated with the anode is a “rotten egg
smell” produced by the presence of sulfur. Do not remove
this anode permanently as it will void any warranties, stated
or implied. An aluminum anode may reduce if not eliminate
water odor problems. The water supply system may require
special
fi
ltration equipment from a water conditioning company
to successfully eliminate all water odor problems. Arti
fi
cially
softened water is exceedingly corrosive because the process
substitutes sodium ions for magnesium and calcium ions. The
use of a water softener may decrease the life of the water
heater tank. The anode should be inspected periodically. If
the anode is more than 50% depleted, the anode should be
replaced.
ANODE MAINTENANCE
•
Flammable hydrogen gases may
be present.
•
Keep all ignition sources away
from faucet when turning on hot
water.
Explosion Hazard
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot
water system that has not been used for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
fl
ammable and explosive. To prevent the possibility of injury
under these conditions, we recommend the hot water faucet,
located farthest away, be opened for several minutes before
any electrical appliances which are connected to the hot water
system are used (such as a dishwasher or washing machine).
If hydrogen gas is present, there will probably be an unusual
sound similar to air escaping through the pipe as the hot water
faucet is opened. There must be no smoking or open
fl
ame
near the faucet at the time it is open.
1. Turn "OFF" the electrical supply to the tank.
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 gal.) as directed in the "Draining and Flushing" section.
5. Using an adjustable pipe wrench, remove the anode
and inspect it. The surface may be rough, full of pits and
crevices, but this is normal. If it is less than approximately
6mm (1/4 in.) in diameter, or the inner steel core is
exposed, the anode should be replaced.
6. Apply
Teflon
TM
tape or sealing compounds approved for
use with potable water, to the threads of the anode and
install into the tank top.
7. Open the cold water supply valve and open a nearby hot
water faucet to purge air from the tank as directed in the
"Filling" section.
8. Check for leaks, repair as required, and re-test.
9. Turn "ON" the electrical supply to the tank.
