PIPE WORK: Copper tubing to BS EN 1057:1996 is recommended for water pipes. Jointing should be either with capillary soldered or compression fittings. Where possible pipes should have a gradient to ensure air is carried naturally to air release points and water flows naturally to drain taps. The appliance has a built-in automatic air release valve, however it should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air. Except where providing u

FLUE SYSTEM 2.9 FLUE CONNECTIONS The provision for satisfactory flue termination must be made in accordance with BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outside air. The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across it at all times. The terminal should be located with due regard for the damage or discolouration that might occur

In addition, it is also possible to use a split (twin pipe) system by fitting a special adaptor to the flue connector and using the aperture for the air vent intake located on the top part of the combustion chamber. To utilise the air intake it is necessary to: 1. Remove the bottom of the air intake by cutting it with a suitable knife (see FIG. 2.7); 2. Insert the elbow into the air intake until it reaches the lower end. (There is no need to use gaskets or sealing compounds). FIG. 2.7 Ø 80 mm F

3.2 DOMESTIC HOT WATER PRIORITY KIT The microSYSTEM is able to be connected to a specially designed Boiler microSYSTEM microSYSTEM 21 RFFI 28 RFFI kit for the management of D.H.W. production. This kit gives priority to Cylinder production of D.H.W. unlike traditional systems where the boiler power is split between C.H. and D.H.W. This generally enables a Contract STI 125 Indirect smaller storage cylinder to be chosen as the boiler’s full output will be channelled into the cylinder allowin

When the installation and filling are completed turn on the central heating system (section 4.4) and run it until the temperature has reached the boiler operating temperature. The system must then be immediately flushed through. The flushing procedure must be in line with BS 7593:1992 code of practice for treatment of water in domestic hot water central heating systems. During this operation, we highly recommend the use of a central heating flushing detergent (Fernox Superfloc or equivalent), wh

4.6 FUME DISCHARGE MONITORING In the boiler, it is possible to monitor the correct operation of the flue exhaust/air intake, checking for a loss of general pressure in the system. Through the use of a differential manometer connected to the test points of the combustion chamber, it is possible to detect the ∆ P of operation of the air pressure switch. The value detected should not be less than 0.55 mbar under conditions of maximum thermal power in order for the boiler to function properly and wi
