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 90

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 2

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

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 35

C and 65

C it recommended that the optimal

temperature is 40

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

general once a year should be regarded as a minimum, even if only occasional usage has occurred. It is a legal

requirement that any service work MUST be carried out by a registered engineer.

Before leaving the factory the heater is pre-set in accordance with the information on the data plate. No adjustment is

necessary and under no circumstances should any of the seals be broken. This includes the removal of the front case

which can only be done by a qualified technician.

19. CLEANING

In addition to routine servicing carried out by a qualified technician it is recommended that the outer case be cleaned

periodically. This should be done with a soft dry cloth. Care should be taken not to damage the LCD control panel.

Periodically the flue terminal should be checked to ensure that it is clean and free of debris. A visual inspection is

recommended and if debris is noticed the appliance should be turned off and the terminal dismantled and cleaned. When

replacing the terminal ensure that it is correctly fitted – refer to section 12 of this manual.

20. SAFETY

It is essential that these instructions are strictly followed for the safe and economical operation of this appliance.

The appliance is a fan-assisted room sealed gas water heater and therefore the flue terminal MUST NOT BE

OBSTRUCTED under any circumstances. If it is damaged, turn off the appliance and consult your installer, or service

engineer. If it is known or suspected that a fault exists on the appliance it MUST NOT be used until the fault has been

rectified by a competent person.

21. PRECAUTIONS AGAINST FREEZING DURING WINTER STORAGE
