REGULATORY INFORMATION Your Dux Endurance Continuous Flow Water Heater has been certified by the Australian Gas Association. The A.G.A. Certification Number is shown on the data plate. This Appliance must be installed correctly by an authorised person. The installation of gas, water, and electricity must conform to local regulations. The installation must also comply with the instructions supplied by Dux. All dimensions referred to in these instructions are in millimetres, unless otherwise specified.
FEATURES AND BENEFITS Congratulations on purchasing the latest technology temperature controlled Dux ® Endurance Continuous Flow Water Heating system. • The Dux Endurance Continuous Flow Water Heater products NEVER RUN OUT of hot water. Whilst electricity, water and gas supplies are connected, hot water is available whenever hot water taps are open. • Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the hot water supplied.
IMPORTANT INFORMATION OFF! Always check water temperature carefully before use. Refer to the WARNING ABOUT HOT WATER on "page 1" of this manual for important safety information. At low water flows, the hot water unit may extinguish without warning. Opening the tap further will restart the appliance. HOT! Do Not touch the unit cover or the flue outlet. Do Not insert objects into the flue outlet. Keep flammable materials, spray cans, fuel containers, pool chemicals, trees, shrubs, etc.
IMPORTANT INFORMATION S O L V E N T Max. 43°C Whilst hot water outlets are open the set temperature may be lowered. However they cannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible. These are safety features. To clean your water controller(s) use a soft damp cloth with a mild detergent. Do Not use solvents! 49°C 50°C There is no need to turn the water controller(s) off after use.
OPERATION WITHOUT CONTROLLERS Dux Endurance Continuous Flow Water Heater products do not use a pilot light. When installed and operated without water controllers, 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.
GENERAL WATER CONTROL INFORMATION MAXIMUM DELIVERY TEMPERATURES Dux Endurance Continuous Flow Water Heaters are factory pre-set to various maximum delivery temperatures depending on model and their intended application. For the majority of applications, the factory pre-set temperature is appropriate. In the unlikely event this is not the case this setting can be increased or decreased by an authorised person such as a licensed plumber. NOTE This does not apply to “50 degree compliant” models.
GENERAL WATER CONTROL INFORMATION Water controllers allow precise temperature control by the user. When used correctly, the hot water unit will deliver the selected temperature, even when the water flow is varied, or more than one tap is in use. Each water controller can be individually programmed, however the water heater can only deliver one set temperature at any time.

IF NO: (You have three water controllers or fewer), go to Question 2.
WATER CONTROLLER INSTALLATION CONNECTING COMMUNICATION CABLES TO THE WATER HEATER Communication cables connect the water heater to water controllers and operate at an extra low voltage (12 Volts DC) which is supplied from the water heater. Communication cables are supplied with the water controllers (15m) and are fitted with spade terminals for connection to water heater. Up to two cables can be connected directly to the water heater. Extension cables are available from Dux.
COMMISSIONING TESTING 1. Before final connection of the water heater purge gas, hot water and cold water supply lines. Swarf in either the gas or water supplies may cause damage. 2. Turn on gas and cold water supplies. 3. Test for water leaks and gas escapes near the unit. 4. Isolate gas supply. Remove test point screw located on the gas inlet connection and attach pressure gauge. 5. Turn the power 'on' at the power point socket and turn on gas. 6.
COMMISSIONING GAS PRESSURE SETTING The regulator is electronically controlled and factory pre-set. Under normal circumstances it does not require adjustment during installation. Make adjustments only if the unit is not operating correctly and all other possible causes for incorrect operation have been eliminated. Instructions for Gas Pressure Setting are to be found in the instruction pocket located inside the appliance front cover.
