MODEL TYPE

Congratulations for choosing a Rheem integrity electronic instantaneous gas water heater.

The model you have chosen is for outdoor installation only. The water heater operates

automatically. When a hot tap is opened, the gas burners ignite to provide immediate

heating of the water. The gas burners extinguish when the hot tap is closed.

HOW HOT SHOULD THE WATER BE?

This type of water heater operates on the principle

of heating water as it passes through the water

heater. The outlet temperature is selected by the

user at the controller (if installed). If a controller is

not installed, the water heater defaults to the preset

outlet temperature. The temperature is then kept

constant by the automatic adjustment of the burner

input and water flow rate (refer to Temperature

Control on pages 7 to 13).

Note: The preset outlet temperature setting of

this water heater cannot be adjusted by the

householder. This setting can only be adjusted

by Southcorp Water Heaters Australia or their

Accredited Service Agent.

HOTTER WATER INCREASES THE RISK

OF SCALD INJURY

We recommend, and it may also be required by

regulations, that an approved temperature limiting

device be fitted into the hot water piping to the

bathroom and ensuite. This will keep the water

temperature below 50°C at the bathroom and

ensuite. The risk of scald injury will be reduced and, if a Kitchen controller is installed, still

allow hotter water to the kitchen and laundry.

TO TURN OFF THE WATER HEATER

If it is necessary to turn off the water heater, such as when going on vacation:

●

Turn off the water heater using the “on/off” button on the controller/s (if fitted).

●

Close the gas and water isolation valves at the inlets to the water heater.

●

If the water heater does not have frost protection, switch off the electrical supply at

the power outlet to the water heater.

Note: The electrical supply should not be switched off for models fitted with frost protection,

unless the water heater is drained. Otherwise damage could result from freezing conditions

(refer to Frost Protection and Draining the Water Heater on page 6 ).

ABOUT YOUR WATER HEATER

TO TURN ON THE WATER HEATER

If the water heater has been drained, screw in the drain plugs at the cold water inlet and

hot water outlet of the water heater and open all of the hot water taps in the house (don’t

forget the shower). Open the cold water isolation valve fully at the inlet to the water

heater. Air will be forced out of the hot taps. As water flows freely from each tap, close

it. Open the gas isolation valve fully at the inlet to the water heater, plug the water heater

power lead into the electrical outlet and switch on. Turn on the water heater at the controller

(if fitted). The water heater will then operate automatically when you open a hot tap.

GENERAL MAINTENANCE

The jacket of the water heater can be cleaned with a soft cloth and warm mild soapy water.

Under no circumstances should abrasive materials or powders be used. Ensure the water

heater flue terminal and air inlet are not obstructed in any way at any time.

The water heater should be serviced annually by Southcorp Water Heaters Australia or

their Accredited Service Agent. Only genuine replacement parts should be used with this

water heater.

SAFETY INSTRUCTIONS

Propane models are designed to operate on Propane

only. The use of Propane/Butane mixture such as

automotive LPG fuel is unsafe and can cause damage

to the water heater.

Do not store or use chemicals or flammable

materials near the water heater.

Do not spray aerosols near the water heater.

Do not place anything on top of or against the

water heater, or in contact with the flue terminal.

The flue gases and the flue terminal on the water

heater are hot when the water heater is operating.

Keep clear of this area to avoid burns.

ELECTRICAL POWER

The water heater uses 240 volt AC electrical power for operation of the control systems and

the combustion fan. The power lead from the water heater must be plugged into a

weatherproof electrical outlet. Take care not to touch the power plug with wet hands.

ABOUT YOUR WATER HEATER

FROST PROTECTION

The water heater may have frost protection. Refer to the rating label on the water heater.

The frost protection system will protect the water heater from damage, by preventing ice

forming in the waterways of the water heater, in the event of freezing occurring. Models

without frost protection are not covered under warranty for damage caused by freezing.

Notes:

●

If it is necessary to switch the power off to the water heater and there is a risk of

freezing, then it is necessary to drain the water heater (refer to Draining the

Water Heater on page 6).

●

The frost protection system will be rendered inoperable if electrical power is not

available at the water heater. Damage caused by freezing due to the unavailability

of power at the water heater, is not covered by warranty.

●

Pipe work to and from the water heater must be adequately insulated to prevent

freezing.

●

The water heater is not suitable for installation in areas where the ambient

temperature falls below -20ºC (including wind chill factor).

●

Refer to Warranty Exclusions on page 28.

DRAINING THE WATER HEATER

●

Turn off the water heater (refer to Turn Off the Water Heater on page 4).

●

Open a hot tap (preferably the shower outlet).

●

Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on

the underside of the water heater. Water will drain from the water heater.

●

When water stops flowing from the water heater, close the hot tap.

Note: It is recommended not to screw the drain plugs back in, until the water heater

is to be turned on again.

ABOUT YOUR WATER HEATER

TEMPERATURE CONTROL

Rheem controllers enable the user to control the temperature of the delivered water

from the outlet of the water heater. There are three controllers suitable for installation

with this water heater. They are the Kitchen controller, Bathroom1 controller and

Bathroom2 controller. One, two or three controllers can be installed. A Bathroom2

controller can only be installed if a Bathroom1 controller is installed. Only one of

each type of controller can be connected to the water heater.

The temperature settings of each type of controller are:

Bathroom1 & 2 37oC to 46oC (in 1oC increments), 48oC, 50oC.

Kitchen 37oC to 46oC (in 1oC increments), 48oC, 50oC, 55oC, 60oC.

The installation of Bathroom controller/s only (ie. no Kitchen controller) limits the

outlet temperature of the water heater to a maximum of 50ºC, regardless of the

preset outlet temperature of the water heater. If Rheem controllers are not installed,

the water heater defaults to the preset outlet temperature. Other manufacturers’

controllers cannot be installed with this water heater.

TEMPERATURE ADJUSTMENT

●

A controller must be on and have priority to be able to adjust the temperature

setting.

●

The temperature adjustment is made by pressing the up (▲) button or down (▼)

button.

●

The maximum temperature setting for the Kitchen controller is 60oC and for the

Bathroom controllers is 50oC.
