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 35
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.
7. ROUTINE SERVICING
To ensure continued safe and efficient operation of the appliance it is recommended that it is checked and serviced at
regular intervals. The frequency of servicing will depend upon the particular installation conditions and usage but in

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
