Alpha InTec² 20SE and 30SE
2 OPERATING THE BOILER
1 INTRODUCTION
Please read these instructions carefully before operating your boiler.
The Alpha InTec range of high efficiency condensing boilers incorporate the latest technology in boiler design. With improved
burner efficiency and reduced electrical consumption together with high quality and reliability.
The boiler output will automatically adjust according to the requirements of the system.
The InTec range are designed to work with most central heating controls however we recommend the Alpha two channel
versions of built in clock or Comfort RF external thermostat programmer.
Alternatively with the use of the Alpha system diverter kit the enhanced Alpha Climatic boiler energy manager can be used
to increase comfort and efficiency. When using the Climatic control unit the efficiency can be further enhanced with the use
of the outside sensor to enable the boiler's built in weather compensation feature.
The boilers will provide both central heating and hot water when required according to the times and temperatures set by the
controls fitted. Hot water cylinder heating will take priority over heating. Simultaneous heating and hot water can be achieved
when using a mid position Y-plan valve or S-plan system.
Fig. 1
Make sure the heating system is filled and the needle on the pressure gauge (item 7 in Fig. 1) is in the green band. If
incorrect refer to Section 4.
The boiler controls are located on the control panel located behind a drop down flap.
* The summer hot water mode and hot water temperature selector switch will only function when using the Alpha System Diverter kit in conjunction
with a hot water cylinder. When using a standard Y or S plan system the boiler must be left in winter mode and only the Heating thermostat used.
