1. INTRODUCTION
The WIDNEY RSW10KL is a wall hung, room sealed, fan assisted, microprocessor controlled fully modulating gas water
heater for providing domestic hot water. It is particularly suitable for Caravan Holiday Home and Park Home use. (Product
details can be found on the data label located on the side of the appliance)
Your water heater will operate and control the water to your taps and showers completely automatically.
The RSW10KL is designed for the modern home and has built in features to ensure safe and reliable operation with minimum
maintenance. It is recommended that the water heater is service annually in accordance with the requirements as detailed in
these instructions; failure to correctly maintain the water heater may invalidate the warranty. If service is required or in the
unlikely event of a fault occurring please in the first instance refer to the fault diagnostic table in this document. The table will
advise on the correct course of action. In most cases the fault diagnostic chart will indicate the problem and by reviewing the
actions in most cases any faults are easily and quickly rectified.
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 please refer to the fault diagnostic table in the document. If rectification is required the
appliance MUST NOT be used until the fault has been rectified by a registered person.
2. PRECAUTIONS AGAINST FREEZING DURING WINTER STORAGE
During cold periods and if the water heater is situated in a place liable to freeze, the water must be completely drained from
the water heater as follows:
1. Turn off the cold water Supply.
2. Open all the hot water outlet taps on the installation.
3. Release the drain plugs fitted at the lowest point of the pipe work.
4. Open the bleed valve on the side of the water inlet fitting a few turns to allow air into the system.
NOTE: There is no drain plug fitted to the hot water heater side of the water heater.
When the operation is finished, close the hot water outlet taps and replace the drain plug and tighten the bleed valve on the
side of the water inlet fitting.
To put the water heater back into service, open the cold water supply.
NOTE: In a Caravan Holiday Home installation there may be a drain cock on the cold inlet under the van directly
below the water heater which may be used.

USING YOUR WATER HEATER
3. 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 model, 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 symbols
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.
Operation of the water heater
To operate the water heater turn on the power from the mains then switch on the water heater via
the on—off switch on the control panel (NOTE: the control panel on power up will light up and display the number 18 which
will then go off). 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
4. 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 or 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 for the water heater to heat the water up to
the set temperature. If this happens then the water flow switch should be set to the
winter position. Always return the switch to the summer position when the air
temperature is above freezing.
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.
If an outlet is too restrictive it will slow down the flow rate and increase the
temperature. For example the shower - ensure the head is free from blockages caused by scale.
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.
If a tap or shower head is too restrictive due to a fault or blockage, the flow rate will be
reduced to below the rate at which the water heater is able to control the temperature
of the water, this may result in the appliance shutting down and an error code being
displayed on the LCD display.
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.
6. 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 a registered service engineer should be
contacted.
