USER GUIDE
1.1
GENERAL REQUIREMENTS
This equipment must be installed by a competent person, registered with a H.S.E. approved
body. All installations must conform to the relevant Gas Safety and Building regulations. Health
& safety requirements must also be taken into account when installing any equipment.
A competent person must also undertake any alterations that require the gas train or flue system
to be broken.
Any interference with a sealed component is forbidden.
Failure to comply with the above may lead to prosecution.
Incorrect use may result in injury and will also invalidate the warranty
The area around the viewing window may become hot during operation. Care should be used to
prevent direct contact with the viewing window and its immediate surroundings.
1.2
PROCEDURE FOR LIGHTING
1.
Ensure that the gas-inlet appliance isolating valve is in the "off" position.
2.
Press the power rocker switch, positioned on the front of the appliance next to the control thermostat, to
bring the equipment on.
3.
Set the control thermostat to a value above that of the stored water.
4.
The combustion fan should start and purge the combustion chamber. The spark generator should
create a spark and the gas solenoid should open. As the gas-inlet appliance isolating valve is closed the
appliance should go to a flame failure condition within 10 seconds this will be indicated by a red lock-out
light on the control panel.
5.
If the above occurs correctly, open the gas-inlet appliance isolating valve and reset the unit by
depressing the red lock-out light on the control panel and a new ignition cycle will begin.
6.
The combustion fan will repeat the pre-purge procedure and attempt to light. Once a flame is
established, the green 'Burner On' lamp, located on the control panel, will illuminate.
1.3
PROCEDURE FOR SHUTTING DOWN
To take the appliance out of service, the power rocker switch should be switched to the off position. If the
appliance in to be shut down for a long period of time, the gas supply should be isolated at the gas-inlet appliance
isolating valve.
1.4
TEMPERATURE ADJUSTMENT PROCEDURE
The setpoint can be adjusted using the dial thermostat on the control panel and monitored using the temperature
gauge.
The setpoint should be adjusted to ensure that the water is stored at 60°C and distributed at 50°C within 1 (one)
minute at all outlets. Care is needed to avoid much higher temperatures because of the risk of scalding. At 50°C
the risk of scalding is small for most people, but the risk increases rapidly with higher temperatures and for longer
exposure times. The risk to young children and to those with a sensory or mobility loss will be greater. Where a
significant scalding risk has been identified, the use of thermostatic mixing valves on baths and showers should be
considered to reduce temperature, these need to be placed as close to the point of use as possible.
