Page 4: About Your Water Heater
Solar heated water can reach temperatures up to 70°C to 80°C for a Vulcan solar direct or indirect pumped system and possibly higher for some other models of solar water heaters. The in-series gas booster operates automatically. - Page 5 We recommend and it may be required by regulations that an approved temperature limiting device be fitted into the hot water piping to the bathroom and ensuite when a 244 series water heater is installed. This will keep the water temperature below 50°C at the bathroom and ensuite. The risk of scald injury will be reduced and if the preset outlet temperature setting has not been adjusted below 55°C, still allow hotter water to the...
- Page 6 Warning: For continued safety of this water heater it must be installed, operated and maintained in accordance with the Owner‟s Guide and Installation Instructions. The Vulcan warranty may not cover faults if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
- Page 7 ABOUT YOUR WATER HEATER PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the water heater must be installed over 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 8 ABOUT YOUR WATER HEATER TO TURN OFF THE WATER HEATER If it is necessary to turn off the water heater: Switch off the electrical supply at the power outlet to the water heater if there is no risk of freezing conditions occurring (refer to note below).
- Page 9 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 the Vulcan warranty (refer to “Terms of the Vulcan Warranty”...
- Page 10 Warning: Temperature controllers must not be fitted to this water heater (244 series) if it is installed as an in-series gas booster with a solar water heater system or if a Water Star water heater is installed because water at a temperature much higher than the controller setting can be delivered.

Page 11: Water Supplies
In a corrosive water supply, the water can attack copper parts and cause them to fail. Where the saturation index is less than –1.0, the water is very corrosive and the Vulcan warranty does not apply to a copper heat exchanger in a continuous flow water heater. -
Page 12: Save A Service Call
Check the items below before making a service call. You will be charged for attending to any condition or fault, which is not related to manufacture or failure of a part (refer to “Terms of the Vulcan Warranty” page 35). - Page 13 Collector area is too small For most installations, the number of solar collectors recommended in Vulcan literature has been proven to provide the required solar energy to meet the average family needs. However, in some circumstances, it may be necessary to install an additional solar collector.
- Page 14 SAVE A SERVICE CALL CLOUDS OF WHITE ‘VAPOUR’ FROM THE FLUE TERMINAL During the heating cycle, it is not unusual to see water vapour clouds steaming from the flue terminal, particularly on cold days. This is normal operation of the water heater. PRESSURE RELIEF VALVE DISCHARGING A pressure relief valve is incorporated into the water heater controls.

- Page 17 Damage to the water heater caused by freezing of the pipe work to or from the water heater is not covered under the Vulcan warranty. Refer to AS/NZS 3500.4 for precautions to be taken for installations in frost prone areas. The water heater is not suitable for installation in areas where the ambient temperature falls below - 20ºC (including wind chill factor).
- Page 18 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 a 244 series water heater and the hot water outlets in any ablution and public areas such as a bathroom, ensuite or public amenities, to reduce the risk of scalding.
- Page 19 In-series gas booster for a Solar Water Heater The temperature limiting device used with a 244 series in-series gas booster as part of a solar water heater installation must have the additional capability of receiving a hot water supply temperature of up to 99°C if the solar water heater does not have an over temperature protection system to limit the water to no greater than 90°C.
- Page 20 CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A Vulcan 244 series continuous flow water heater can be installed as part of a circulated hot water flow and return system in a building. Notes: the preset outlet temperature setting of the water heater must be set to at least 60°C.

Page 27: Commissioning
COMMISSIONING All water heaters are tested and adjusted before dispatch from the factory, however further adjustments may become necessary because of local conditions. TO TURN ON THE WATER HEATER Open all of the hot taps in the house (don‟t forget the shower). Open the cold water isolation valve fully at the inlet to the water heater. - Page 28 COMMISSIONING Gas Inlet Test Point Pressure To check the gas inlet pressure: Close any hot taps and ensure the burners are not operating. Close the gas isolation valve at the gas inlet to the water heater. Locate the gas inlet test point on the gas connection to the water heater.
- Page 29 Warning: The removal of the front panel will expose 240 volt wiring. Take care not to touch wiring terminals. Note: If a 244 series model is installed as an in-series gas booster for a solar water heater, then during this procedure the temperature of the water entering the in-series gas booster must be below 58°C. Otherwise the gas burners will not ignite and the operational gas pressures cannot be measured.
