IWH-1.5-13.5 Instantaneous Gas Water Heater

Installation and Operating Instructions

Part Numbers: 051460 (Black Door); 051459 (White Door)

The IWH-1.5-13.5 instantaneous gas water heater is designed in accordance to the Australian

Standards for installation in recreational vehicles. This water heater is not for use in houses, space

heating or marine application.

This water heater is designed to produce water with a temperature rise of 37°C above ambient, at a

flow rate of 5 litres per minute. Exceeding the flow rate will result in cooler water. If the ambient

temperature is very low (i.e. close to freezing), the water in the supply tank will be cold, resulting in

cooler than expected water.

WARNING: If the information in these instructions is not followed exactly, a fire or explosion may result

causing property damage, personal injury or loss of life.

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any

other appliance.

WHAT TO DO IF YOU SMELL GAS

 Evacuate all persons from the caravan or RV.

 Shut off the gas supply at the gas container or source.

 DO NOT touch any electrical switch or use any phone or radio in the vehicle.

 DO NOT start the vehicle’s engine or electric generator.

 Contact the nearest gas supplier or qualified service technician for repairs.

 If you cannot reach a gas supplier or qualified service technician, contact the nearest fire

station or emergency services.

 DO NOT turn on the gas supply until the gas leak(s) has been repaired.

Installation, commissioning and service must be performed by a licensed gas fitter, service agency,

OEM or the gas supplier. Failure to do so will void the warranty.

WARNING:

To avoid scalding, water supplied to the shower and hand basin must pass

through a tempering valve to restrict the water temperature to 50 degrees C. We

recommend the John Guest tempering valve 12mm – code 042586.

WARNING: Installation of this product must comply with the requirements of the

Plumbing Code of Australia (PCA)

WARNING:

Do not block any pressure relief valves if fitted when installing this Hot

Water System.

Connection Water of the Supply and Hot Water Outlet The cold water inlet and the hot water outlet are connected via 2 standard ½” male fitting. Use a rubber seal or other removable sealants. Piping and components connected to the heater shall be suitable for use with potable water. When tightening water connections to the water line, be sure to back up the fittings with a wrench as to not damage the copper water tubing. Re-tighten the compressions nuts on the water fittings.

Connection Electrical Supply and Remote Control The water heater is designed for 12 VDC (10…15V, negative ground). The power leads are on the back of the heater and should be connected via a breaking switch to the 12 V system of the RV. The red wire is positive (+) and the black wire is negative (see sticker). A breaking switch is recommended for safety reasons, so the water heater could be switched of separately.

Operating Instructions and first operation test Note to installer: You must test the operation of this appliance after installation. 1. 2. 3. 4. 5. Pressurize the water system by turning on pump or city water pressure. Purge all air from system by turning on the taps until a steady stream of water flows from the taps. Turn off taps. Turn on the 12 VDC power supply. A testing sequence on the remote starts and after a few seconds, the display shows the last selected temperature.

6. 7. When the hot water tap is turned off, the heater will shut off and remain in “stand-by mode”. With the ON/OFF button of the remote control, you can switch off the water heater so the burner is not activated via the water flow. Troubleshooting The IWH-1.5-13.5 is equipped with a microprocessor based self-diagnostics system. Possible errors are displayed on the LED display of the remote control. Failure code shown in the display E1 Burner flame did not ignite within 10 seconds.

6. 7. 8. Be sure the gas valve at the tank is “On” and there is gas in the tank. Be sure that the water flow is at least 1.5 l/minute. If you have changed the gas bottle, it takes a while until the gas lines are filled with gas and the gas reaches the water heater. If E1 is displayed, there is no flame detection. Close the water tap for a few seconds and open it again. Depending on the length of the gas line, it may take several attempts until you have ignition.

The water system can be filled with RV, non-toxic anti-freeze, which doesn’t affect copper and brass. When you see the anti-freeze coming from the hot water tap, the heater is protected.
