Before using or operating your water heater Ensure the installer talks to you about the use and care of this appliance and that you understand these instructions. The installer also needs to complete: • their installer details (p. 27) • the Commissioning Checklist (verifies the water heater has been installed and commissioned correctly) supplied with the appliance The installer needs to leave the checklist and operation manual with you. Read these instructions for an overview on what is detailed in this manual about the use, care and servicing of your Rinnai continuous flow water heater. Important The Rinnai Infinity water heater requires power to prevent damage in freezing conditions. DO NOT disconnect the power if there is a likelihood of freezing without draining the water heater. Instructions for draining can be found at the back of this manual. Principle of operation The opening of any hot water tap will automatically start the appliance. Once water is flowing through the appliance the burner will be ignited by electronic ignition. When the hot water tap is closed and water flowing through the appliance has stopped the burner flame will extinguish. OFF! OFF! COLD COLD COLD COLD OFF! OFF!

Page 6: Warning About Hot Water
Warning about hot water Excessively hot water is dangerous. Rinnai continuous flow water heaters through the use of water controllers allow you to control the temperature of hot water to safe levels. Water temperatures above 55 °C can cause instant severe burns, such as scalding and may even result in death. Those most at risk; children, disabled, elderly, and the sick. Hot water at 65 °C (a common water temperature in New Zealand) can severely burn a child in less than half a second. At 55 °C (preset temperature for domestic Rinnai continuous flow water heaters) it takes a half minute. Always • Test the water temperature with your elbow before placing your child in the bath and feel the water yourself before bathing or showering • Supervise children whenever they are in the bathroom • Make sure the hot water tap is turned off Consider Installing child proof tap covers or child resistant taps, both will prevent a child being able to turn on the tap. Never Leave a toddler in the care of another child. They may not understand the need to have the water temperature set at a safe level. General safety Do not: Keep flammable materials, • Touch the unit spray cans, fuel cover or the containers, pool flue outlet chemicals, trees, shrubs etc. well HOT! • Insert objects clear of the flue into the flue outlet. -
Page 7: General Information
The colour of the flue outlet may change colour over time due to condensate in the exhaust gases. This is normal. Flue outlet This discolouration will not damage the unit and will not affect the performance of the water heater. Frost kits Frost protection is fitted as standard on all models. Frost protection operates automatically (as required) whenever the appliance is connected to the electric power supply. If power has failed and there is a risk of damage from frost, turn off the gas supply to the unit and open a tap slightly to allow flow through the unit. This may prevent damage from freezing. If the appliance is not going to be used for an extended period and the electric power supply is disconnected, turn off the water and gas supplies and arrange for your plumber to drain all water from the appliance to prevent frost damage. If for practical reasons a plumber is unable to drain your system we have an instruction sheet on how to drain the unit at the back of this manual. Turn Water Off Filter Drain Turn Gas Off Valve Drain Water Cold Installation by a licensed tradesperson Improper installation, adjustment, service or maintenance can cause serious injury, property damage or death. Please ensure your installation is completed by a licensed tradesperson.

- Page 9 General information Servicing Rinnai has a service and spare parts network with personnel who are fully trained and equipped to give the best advice on your Rinnai appliance. If your appliance needs servicing, please call Rinnai (0800 746 624) from a land line and select option one for a service centre in your area. For reliable operation Rinnai continuous flow water heaters in domestic applications should be serviced every two years (including inspection of the flue system if installed). A service record has been provided at the back of this manual. For commercial applications Rinnai has a recommended Commercial Maintenance and Servicing Schedule. This is available on request or via our website - www.rinnai.co.nz. Regular servicing is not covered by the Rinnai warranty. Do not attempt to carry out any service work other than that mentioned in the troubleshooting section. If you have any other faults or problems, please refer to your installer or contact Rinnai. Solar installations There is a recommended system layout for Rinnai continuous flow water heaters used in solar installations. It is important your installer configures your solar system correctly as water heaters in solar installations produce higher than normal temperatures. Rinnai water controllers cannot be used with Rinnai continuous flow water heaters in solar installations as the hot water does not always pass through the continuous flow unit. Temperature limit - factory preset The Rinnai continuous flow water heaters are factory preset to a temperature limit of 55 °C (excluding one commercial model - Infinity HD200 external). Temperature controllers are available to allow precise digital temperature control—a great safety feature if you have young children. Controllers can be fitted at any time (except in solar installations) after installation of the hot water unit. Water flow The flow will vary slightly depending on the incoming water temperature 43°C and temperature selected. For example the water flow will be higher at 43 °C than at 55 °C. There is also a minimum flow rate required for the continuous flow unit to start. So if a hot water tap is only opened a fraction there may not be enough flow to start the unit.

If water is flowing before a controller is turned on, the water heater will not heat the water. Turn off the tap for a few seconds then turn on again. Ignition problems If the water heater fails to ignite, the ‘In Use’ indicator will not illuminate. The water heater will not attempt re-ignition until water flow is stopped for a few seconds and then re-started. When gas bottles have been changed or the gas supply is disrupted (controller may display error code 11 or 12) ignition may fail and the ‘In Use’ indicator won’t be on. The water flow may need to be stopped and re-started several times before the appliance will remain alight. Rinnai New Zealand Ltd Continuous Flow Water Heater Operation Manual 03-11...
