ABOUT YOUR WATER HEATER

WATER HEATER APPLICATION

This water heater is designed for use in a single family domestic dwelling for
the purpose of heating potable water. Its use in an application other than this
may shorten its life.

MODEL TYPE

The Rheem

®

water heater model you have

chosen is suitable for outdoor installation only.
The model is a high efficiency, quick recovery
8A0 series Rheem Stellar

™ 330 stainless

steel water heater.

Water  is  stored  in  a  stainless  steel  cylinder
and heated by a gas burner located under the
cylinder.  The  heat  produced  by  the  burner  is
transferred to the water through the base, top
and side walls of the storage cylinder with flue
baffle  rings  capturing  heat  to  improve
efficiency.  The  gas  supply  to  the  burner  is
controlled  by  the  thermostat  so  the  water  is
heated to a constant temperature.

Automatic  safety  controls  are  fitted  to  the  water  heater  to  provide  safe  and
efficient operation.

HOW HOT SHOULD THE WATER BE?

The  water  heater  features  a  user  adjustable
thermostat,  which  allows  you  to  personally
choose the most suitable temperature for your
hot  water  needs.  Refer  to

“Temperature

Adjustment”

on page 7.

To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.

Note:

AS 3498 requires that a water heater

provides  the  means  to  inhibit  the  growth  of
Legionella  bacteria  in  potable  water.  This
water  heater  can  satisfy  this  AS 3498
requirement  provided  it  is  operating  and  the
thermostat setting is 60°C or higher, including
when  it  is  used  as  an  in-series  booster  water
heater for a solar water heater.
