10. SELECTING THE POSITION

Decide where the heater is to be fixed taking into account the installation requirements required under the relevant standards and sections 1, 2,3,12 of these instructions.

11. WALL MOUNTING The Water Heater can either be mounted with the flue system exiting to the rear or side of the appliance. For Wall mounting with flue to the rear refer to paragraph entitled ‘Flue installation to the rear’.

Materials around the flue system – The outer flue will reach a maximum temperature rise of 35oC. Care should be taken in ensuring that any materials touching the outer flue are capable of withstanding this temperature for extended periods. It is recommended that the rubber inner and outer seals are pushed into the wall aperture before sealing. This will ensure that the outer flue pipe fits centrally in the wall aperture.

Flue installation to the side: See diagram Bi

The water heater should be mounted on a suitable wall with sufficient structural strength to ensure adequate support.

1. Mark the position of the fixing holes and the outlet aperture in the wall as indicated in diagram Bi. Ensure that the position of the flue outlet meets with the requirements of the relevant standards and is located as detailed in section 2.

2. Cut the hole for the flue liner through the wall of the home.

3. Fix the flue system to the water heater see section 12.

4. Fix the water heater securely through the fixing brackets located at the base and top of the unit.

5. Go to section 12.

Flue installation to the rear: See diagram Biii

This method of installation requires a fixing kit part no. RSWFIX01. The fixing kit comprises of two fixing brackets to replace the fixing brackets fitted to the water heater and a wall closure plate. The water heater should be mounted on a suitable wall with sufficient structural strength to ensure adequate support.

2. Cut the hole for the flue liner through the wall of the home.

3. Align the closure plate with the hole in the inner wall and mark around the closure plate.

4. Cut out the inner section of the wall to fully recess the inner wall closure plate diagram Biii.

5. Insert the closure plate into the wall opening and fix with suitable fixings.

12. FLUE INSTALLATION Positioning:

• The water heater MUST be installed so that the terminal is exposed to the external air.

• It is important that the position of the terminal allows free passage of air across it at all times.

• It is ESSENTIAL TO ENSURE, that products of combustion discharging from the terminal cannot re-enter the

building, or vehicle, through ventilators, windows, or other sources of natural air infiltration, such as other flues etc, with the exception of doors, but not the opening windows thereof. The minimum acceptable dimensions from the terminal to obstructions and ventilation openings must be as detailed in section 2.

Installing the flue system: IMPORTANT The standard horizontal flue kit supplied with the RSW10KL is part number RSWFK1M. This kit provides for 1 meter of flue length and one 900 elbow. Note: DO NOT INSTALL THIS APPLIANCE WITH MORE THAN ONE 90

Elbow (Bend) and more than 1.0 metre of flue length. Never use a flue kit not specifically approved for use with this appliance.

NOTE: Where the home is pre-installed with the RSW10KL please consult the home manufacture for replacement part numbers.

NOTE: The inner flue pipe of the terminal must be cut accurately and must always be 100 mm longer than the outer flue in order to ensure correct location in the terminal and elbow. NOTE: The outer pipe has two holes at one end to

fix the terminal always cut the pipe at the opposite end to these two holes.

To calculate the correct length of the outer flue use the following formula and refer to diagram Ei

Formula: dimension X + Y + 20 mm (Note Dimension X is the distance between the inner wall of the home and the end of the elbow without the sealing collar attached; in the case of rear flue installation the appliance should be fitted with installation Kit RSWFIX01 if this kit is used then the dimension X = 10mm.)

For calculating the inner flue lengths use the overall length of the outer flue liner when cut to size and add 100mm.

Two sealing collars are provided to seal the external pipe against the internal and external wall.RSWSC01.

The flue assembly must be installed with a slight downwards incline of 20 towards the terminal to prevent the ingress of rain water, which may damage the heater. See diagram Eii.

Terminal Guard: if the position on the outlet terminal is less that 2 meters above ground level it is recommended that a terminal guard be fitted.

Connecting the flue system:

Refer to diagram to assist in assembly.

1. Slide the inner flue pipe into the outer flue pipe ensuring that the spacer on the inner flue pipe is evenly positioned - Note for flue lengths less than 300 mm the spacer is not required, see diagram Eii.

2. Fit the clamping rings onto the elbow. Note:

ensure that the smaller diameter of the clamping ring seal is facing the water heater outlet spigot, see diagram Eiii.

3. Connect one end of the elbow to the water heater and secure the clamping ring.

4. Slide the inner flue pipe into the elbow then slide on the inner rubber collar over the flue pipe and insert the outer flue pipe through the clamping ring and into the elbow the secure the clamping ring, see diagram Eiv.

Note: if fitting rear flue the inner rubber collar should not be fitted.

Note; the inner flue pipe must protrude 55 mm beyond the outer flue pipe, see diagram Eiv.

8. Fit the water heater to the wall by inserting the flue pipe through the hole in the wall and securing the water heater through the fixing brackets into the pre drilled holes as detailed in section 11.

5. On the outside of the home slide the outer collar over the outer flue pipe.

6. From the outside of the home locate the terminal onto the inner flue pipe ensure that the rubber seal is fitted to the terminal before fixing to the flue pipe then push the terminal over the outer flue pipe.

NOTE The maximum gap on Fig Eiv ensure that the inner flue pipe is correctly aligned in the elbow on the water heater before pushing on fully. When the terminal is in the correct position the holes in the terminal will align with the holes in the outer flue pipe. Secure the terminal to the outer flue pipe with the fixings provided.

7. If applicable slide the inner collar up to the inner wall and seal with sealant. See diagram Evi

INSTALLATION COMPLETION

13. WIRING

Observe all the usual precautions to ensure that the electricity supply is isolated before beginning any installation work. The heater should be wired as described in section 5.

Important: this appliance must be earthed.

14. GAS AND WATER CONNECTIONS

Connect the gas and water connections to the appliance using the appropriate fittings. Ensure that the pipe sizing, material and connections comply with sections 6, 7, and 8 of this manual.

SETTING AND FIRST USE

15. THE CONTROL SCREEN

The control screen displays the water temperature, fan operation, burner operation and water delivery and fault diagnostics information.

In normal operating conditions the screen will display the set water temperature and operational mode, for example if the water heater is not being used the temperature will be displayed together with a shower head. If the water heater is working then the shower head will display a water effect and the burner and fan will flash on and off.

The temperature of the water that will be delivered from the appliance is set by using the up and down buttons on the left hand side of the panel.

To operate the water heater turn on the power from the mains – (the control panel will light up and display the number 18 which confirms that PCB mode and settings are correct for this appliance, the display will then go to a non-illuminated condition), then switch on the water heater via the on—off switch on the control panel. The water heater is now in operational mode and will automatically start up when the hot water tap is used. Water temperature can be set between 350C and 650C it recommended that the optimal temperature is 400C

16. GENERAL GUIDANCE NOTES ON HOT WATER DELIVERY

The temperature of the hot water is governed by both the ambient temperature of the cold water supply and its flow rate through the water heater. The flow rate of the hot water is controlled by the hot outlet tap / shower.

Water Flow settings: The appliance is fitted with a manual water flow adjuster which should be in the summer position for normal operation; however in very cold conditions the water inlet temperature may be too low to heat the water effectively. If this happens then the water flow switch should be set to the winter position.

The water heater can theoretically supply more than one outlet simultaneously; however in practice the tap which is nearest will receive the most hot water. If the shower is in use and a kitchen tap is opened virtually all the hot water will be diverted to the kitchen as it offers the least resistance.

• Due to the restrictive nature of simple mixer showers it is wise to turn the temperature selector down on

the water heater before using the shower.

DO NOT PLACE YOUR HANDS under the tap or use the shower until this initial flow has passed.

Allow time (30 seconds) for the temperature to stabilise after making an adjustment at the tap before making further adjustments.

17. APPLIANCE SAFETY LOCK-OUT

This water heater has a fault indicator built in to it on the front display, whenever a malfunction is detected in the water heater the display panel will indicate a fault code and turn the water heater off. Please refer to the fault code section to diagnose a fault.
