6.5. Testing – User Controls
Check all external time and temperature controls are fully operational and give the expected response to
user operation. Check the operations of the on/off and reset switch on the boiler.
When the burner is lit, the dot D1 will be on constant and the digital display will indicate the boiler flow
temperature.
A fault is indicated by flashing dot 'D2' and the fault code is displayed on the digital display. To reset press
'Set/Reset' button S1.
6.6. Frost Protection
The boiler has frost protection built into its operation programme but requires the gas and electricity to be
switched on. This programme operates the burner and system pump if the temperature inside the boiler falls
o
below 4 C. This device is designed to protect the boiler and any other exposed area of the system should be
protected separately by a frost thermostat.
6.7. Instruct the User
A demonstration of the lighting procedure and advise of safe and efficient operation should be given to the
user. The use and operation of the heating system controls should also be demonstrated to the user along
with the use and maintenance of any other equipment e.g. scale reducers that may be fitted to the system.
Advise that to continue with safe and efficient operation of the boiler it is recommended that the boiler is
checked and serviced at a regular interval of a minimum of once a year.
Advise that like all condensing boilers this appliance will produce a plume from the flue terminal in cold
weather and this is normal for a high efficiency boiler.
Advise of the user of the precautions necessary to prevent damage by frost and freezing conditions if the
system is out of use. Along with a need to keep the electrical and gas supplies switched on to enable the
automatic frost protection to work.
Draw attention to the law that any servicing should be carried out only by a competent person and if
applicable to the current issue of the Gas Safety (Installation & Use) Regulations, Section 35, which imposes
a duty of care on all persons who let out any property containing a gas appliance.
