Page 4: About Your Water Heater
MODEL TYPE ® Congratulations for choosing a Raypak water heater. The model you have chosen is suitable for either indoor or outdoor installation depending on use of the appropriate installation kit. - Page 5 Raypak distributor, qualified installer, or Rheem Service agent. The Raypak warranty can become void if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
- Page 6 ABOUT YOUR WATER HEATER TO TURN ON THE WATER HEATER WARNING! If you smell gas do not attempt to turn on the water heater. Fill the system with water (refer to “To Fill the Water Heater” on page 29) Open the gas isolation valve fully at the inlet to the water heater. Plug in the power supply cord at the power outlet.

Page 7: How Your Water Heater Works
HOW YOUR WATER HEATER WORKS The water heater consists of a gas burner, a combustion chamber lined with refractory tiles and a heat-exchanger made of finned copper tubes. Hot flue gases from the burner pass between the fins on the heat exchanger tubes and heat is transferred first to the fins and then by conduction into the water. - Page 8 HOW YOUR WATER HEATER WORKS BURNER IGNITION 147 Hi/Lo Models The water heater utilises an automatic burner ignition system, which lights the main burner gas when the thermostat registers a need for heating. A hot surface igniter (HSI) heats up when there is a call for heating. When the HSI probe is up to temperature, a valve opens allowing gas to the main burner and this is ignited by the HSI probe.

WARNING: Hotter water increases the risk of scald injury. 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. - Page 10 SAVE A SERVICE CALL BURNER WILL NOT LIGHT Is there gas to the water heater? Check the gas isolation valve on the gas supply line is open. Is there a normal gas supply to the rest of the premises? Try lighting another gas appliance. If there is no gas call your gas provider. Is the ignition system ‘locked out’? Try resetting the water heater.

INSTALLATION THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING INSTALLATION STANDARDS The water heater must be installed: by a qualified person, and in accordance the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS 5601 or AS/NZS 5601.1, as applicable under local regulations, and all local codes and regulatory authority requirements. - Page 13 INSTALLATION SAFE TRAY Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and regulatory authority requirements.
- Page 14 INSTALLATION OUTDOOR INSTALLATION For servicing allow at least 750 mm in front of the water heater for burner removal and 450 mm on the water connections side for heat exchanger servicing. The water heater must NOT be installed inside any roofed structure or under eaves, roof overhangs, or pool decks.
- Page 15 INSTALLATION COLD WATER SUPPLY Water Heating Applications Where the cold water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 18). Mechanical/Process Heating Applications A cold water feed regulator (Pressure Reducing Valve) should be installed on the cold water make up line.
- Page 16 INSTALLATION HOT WATER DELIVERY (WATER HEATING APPLICATIONS) This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the water heating system and the hot water outlets in any ablution and public areas such as bathrooms, ensuites or public amenities, to reduce the risk of scalding.

CONNECTIONS – PLUMBING IMPORTANT: When installing a new water heater to an old or existing system, it is a requirement that the system and its equipment be thoroughly inspected and if necessary, drained and flushed with clean fresh water, before the new water heater is connected. - Page 19 CONNECTIONS - PLUMBING The table below provides indicative pipe and pump sizes for typical installations Minimum Manifold Header Model Pump Branch Size Size Required (mm) Speed inches Series Unit Units Units Units 20-60N PUMP SELECTION In order to obtain the best possible water flow in the system a correctly sized pump must be installed. Refer to the Flow Rate and Pressure Drop table below and allow for the system head pressure when sizing the pump.
- Page 20 CONNECTIONS - PLUMBING MECHANICAL HEATING All high points of a mechanical heating system should be provided with manual bleed points or fitted with automatic air vents. The design of the system must be such that the water heater is provided with adequate water flow and pressure at all times (refer to „Pump Selection‟...

CONNECTIONS – ELECTRICAL All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the 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. - Page 22 CONNECTIONS - ELECTRICAL WIRING A POWER FLUED SYSTEM TO THE WATER HEATER An indoor model can be wired to a power flued system. A power flued system must be designed by a qualified person to suit the particular installation. The power flue system must be interlocked with the water heater(s) to prevent the water heater(s) from operating if the power flue is not working.
