The power supply cord and plug must be replaced with a genuine replacement part available from Rheem.
- Page 6 HOW LONG WILL THE WATER HEATER LAST? There are a number of factors that will affect the length of service the water heater will provide. These include the water quality, the water pressure, temperature (inlet and outlet) and the water usage pattern. However, your water heater is supported by a comprehensive warranty (refer to page 41).

Page 7: How Your Water Heater Works
Baffles are placed between the tubes to control the flow of the hot flue gases and ensure efficient operation of the water heater. The refractory tiles insulate the combustion chamber to minimise loss of heat and protect the surroundings from the temperature of the burner flames. - Page 8 There is no need to switch the water heater off when it is not in use. The thermostat is fully automatic and only allows the gas control to open when the burner requires gas for heating. To adjust the thermostat settings refer to “Temperature Control”...

• Water heater size Do you have the correct size water heater for your requirements? The sizing guide in the Raypak sales literature and on the Rheem website (www.rheem.com.au) suggests average sizes that may be needed. WATER HEATER NOT OPERATING The ignition system may have ‘locked out’. - Page 10 EXPANSION CONTROL VALVE RUNNING If an expansion control valve is fitted in the cold water line to the water heater (refer to page 19) it may discharge a small quantity of water instead of the pressure relief valve on the water heater. The benefit is that energy is conserved as the discharged water is cooler.

Page 11: Regular Care
PRESSURE RELIEF VALVE This valve is located in the in/out header of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume. -
Page 12: Installation
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING Check the water heater is suitable for the gas type available. The gas type is marked on the side panel near the gas connection entry and shown on the rating label. - Page 13 Ceiling The normal water heater design is with the water pipe entry from the left hand side on 109 models and the rear for 147 models. For servicing purposes allow at least 750mm in front of the water heater for burner tray removal.
- Page 14 The following distances extracted from the Australian Gas Installations Standard AS 5601 must be observed: • At least 500 mm between the top of the flue terminal and the eaves.
- Page 15 HIGH WIND CONDITIONS In areas where high winds frequently occur, it WILL be necessary to: • Locate the water heater a minimum of one (1) metre away from high vertical walls. • Install a wind break to protect the water heater from the prevailing winds.

GAS INLET The gas connection is made at the right hand end of the water heater for 109 Models and at the inlet of the gas control for 147 models. The pipe work must be cleared of foreign matter before connection and purged before attempting to light the water heater. - Page 20 RELIEF VALVE DRAIN A copper drain line must be fitted to the relief valve to carry the discharge clear of the water heater. Connect the drain line to the relief valve using a disconnection union. The pipe work from the relief valve to the drain should be as short as possible and fall all the way from the water heater with no restrictions.

Wiring Rules AS/NZS 3000 and local authority requirements. The water heater is supplied with a 1.8 metre lead and plug and requires a 240 V 50 Hz general purpose outlet (GPO) to be located within 1.0 metre of the installation. NOTE: For outdoor installations the GPO must be weatherproof. - Page 23 For applications requiring connection to a building management system, an optional BMS kit suitable for 147 On/Off models ONLY must be fitted to the water heater to provide ‘run’ and ‘fail’ status. 109 and 147 Hi/Lo models cannot be connected to a building management system.

Page 33: Burner Pressure Adjustment
Natural Gas - 1.13 kPa If this minimum cannot be achieved, it may indicate the meter or the gas line to the water heater is undersized. It is important to ensure that an adequate gas supply pressure is available to the water heater when other gas burning appliances, on the same gas supply, are operating. - Page 34 Hi/Lo Models To adjust the burner pressure on a water heater with a White Rodgers 36E20 Type 301 Hi/Lo gas control, proceed as follows: 109 Hi/Lo Models • Remove the screw and washer from the burner feed pipe pressure tap.

Page 35: Temperature Control
The installing plumber may have a legal obligation to ensure the installation of this water heater meets the delivery water temperature requirements of AS/NZS 3500.4 so that scalding water temperatures are not delivered to a bathroom, ensuite, or other ablution or public area. - Page 36 • Wait 12 seconds, The current temperature in the water heater will now be displayed and programming complete. The recommended set points for SE.1 and SE.2 are 82°C and 75°C respectively for a heating system. However, it may be necessary to increase SE.2 if there is an unacceptable variation in room temperature.
- Page 37 (pocket) fitted in the outlet header and senses the temperature of the water leaving the water heater. The high limit temperature setting is adjusted by removing the front cover (loosen one Phillips-head screw) and turning the adjuster.
