5.1 ENERGY SAVING TIPS
•
During extended periods of non use, turn the boiler off.
•
Set up a regular program of preventative maintenance for the boiler. Check heat exchanger,
controls, burner operation etc.
•
For areas where there is a danger of freezing, water should circulate through your boiler even
if the heating is off.
5.2 MAINTENANCE
•
It is recommended that the following items are professionally checked at least every six
months and at the beginning of every heating season.
•
Examine the balanced flue or indoor draught diverter. Make sure there are no obstructions to
the flow of air to, or flue products from, the appliance.
•
Visually check the main burner and pilot flames. If the flame appears yellow, the burner
should be cleaned by a qualified service technician.
•
Keep the boiler area clear and free of combustibles and flammable liquids. Chlorine should
not be stored in the vicinity of the boiler. Chlorine vapours, when drawn through a boiler,
can rapidly cause corrosion of the heat exchanger.
•
Keep the boiler area free from garden refuse and debris. This will help prevent insects
nesting in the unit and ensure extended life and reliability of your boiler.
5.3 CONTROL SYSTEMS
5.3.1 DESCRIPTION
The sophisticated digital thermostat provides temperature read out, set point temperature and
operating status of the boiler. The electronic display indicates the operational status of the boiler
and any fault conditions.
5.3.2 TEMPERATURE DISPLAY
•
The temperature display indicates water temperature in the outlet (flow) of the boiler.
Therefore the pump must be operating for an accurate water temperature to be displayed.
•
Water temperature can be set between 55˚C to 90˚C. (35˚C to 55˚C floor heat). To select
your desired water temperature press the up or down button repeatedly until the desired
temperature is reached.
•
Fitting of an external switch allows temperature set-back via two adjustable set points. (See
