REDUCING HEAT LOSSES
The cold water line to and the hot water line from the water heater must be
insulated in accordance with the requirements of AS/NZS 3500.4. The insulation
must be weatherproof and UV resistant if exposed.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the
Rheem warranty when the total dissolved solids (TDS) content in the water is
less than 2500 mg/L and when the correct colour coded anode is used. If an
incorrect colour coded anode is used in the water heater, any resultant faults will
not be covered by the Rheem warranty. In addition, the use of an incorrect colour
coded anode may shorten the life of the water heater cylinder.
The correct colour coded anode for the water supply being used must be
selected and fitted to the water heater for the Rheem warranty to apply to the
water heater cylinder (refer to
Selection chart
on page 19). The black anode is typically fitted as standard.

If the water supply has a TDS greater than 150 mg/L and a green anode has not
been changed to a black anode, or if the TDS is greater than 600 mg/L and the
anode has not been changed to a blue anode, there is the possibility the anode
may become overactive and hydrogen gas could accumulate in the top of the
water heater during long periods of no use. In areas where this is likely to occur,
the installer should instruct the householder on how to dissipate the gas safely
"Caution"
(refer to
SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the
water heater jacket, we recommend the use of self-drilling screws with a
maximum length of 13 mm. Should pre drilling be required, extreme caution must
be observed when penetrating the jacket of the water heater.
Note: If the cylinder is damaged as a result of attaching pipe clips or
saddles to the jacket, any resultant faults will not be covered by the Rheem
warranty.
