1. GENERAL INFORMATION This manual is an integral and essential part of the product. It should be kept with the appliance so that it can be consulted by the user and our authorised personnel. Please carefully read the instructions and notices about the unit contained in this manual, as they provide important infor mation regarding the safe installation, use and maintenance of the product. For operating instructions please consult the separate User’s Manual. CO034A 1.
5 - If called for by point. 3, dismantling and cleaning of the combustion chamber. 6 - If called for by point. 4, dismantling and cleaning of the burner jets. 7 - Visual check of the primary heat exchanger: - check for overheating in the blade assembly; - clean the exhaust fan if needed. 8 - Adjustment of the flow rate of the gas: flow rate for lighting, partial load and full load. 9 - Check of the heating safety systems: - safety device for maximum temperature; - safety device for maximum pressure.
2. INSTALLATION The technical information and instructions provided herein below are intended for the installer so that the unit may be installed correctly and safely. 2.1 REFERENCE STANDARDS The installation and initial start up of the boiler must be by a CORGI Approved Installer in compliance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e.. CORGI .
2.3 OVERALL DIMENSIONS LEGEND: A = Central Heating Flow (3/4”) B = Domestic Hot Water Outlet (1/2”) C = Gas Inlet (3/4”) D = Domestic Cold Water Inlet (1/2”) E = Central Heating Return (3/4”) 2.4 CLEARANCES In order to allow for access to the interior of the boiler for maintenance pur poses, the boiler must be installed in compliance with the minimum clearances indicated in FIG. 2.2 FIG. 2.1 QT002A 2.
marked “L”. Note: The diagrams for the electrical system are indicated in section 2.11. Warning, this appliance must be earthed. External wiring to the appliance must be carried out by a qualified technician and be in accordance with the current I.E.E. Regulations and applicable local regulations. The Genus range of boilers are supplied for connection to a 230 V~ 50 Hz supply. The supply must be fused at 3 A.
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.
2.9 FLUE SYSTEM The provision for satisfactory flue termination must be made as described in BS 5440-1. The appliance must be installed so that the flue terminal is exposed to outdoor 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 on buildings in the vicinity.
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. 2.8); 2. Insert the elbow into the air intake until it reaches the lower end. (There is no need to use gaskets or sealing componds).

In calculating the lengths of the pipes, the maximum length “L” must also take into consideration the values for the exhaust/air intake end terminals, as well as 90° elbows for coaxial systems. The C52 types must comply with the following requirements: 1 - The exhaust/ air intake pipes must have the same diameter of ø 80 mm.

3.4. INITIAL START-UP THE CHECKS TO BE RUN BEFORE INITIAL START-UP ARE AS FOLLOWS: 1.
3.6 The flue connector has two apertures, readings can be COMBUSTION ANALYSIS taken for the temperature of the combustion by-products and of the combustion air, as well as of the concentrations of O2 and CO2, etc. . To access these intakes it is necessary to unscrew the front screw and remove the metal plate with sealing gasket.
5. ANTI-FROST DEVICE: The boiler is equipped with a device that, in the event of the water temperature going below 5°C, the 3-way diverter valve switches to domestic hot water and the burner ignites at the minimum power until the boiler water reaches a temperature of about 50°C. This device operates only if the boiler is functioning perfectly and: - the system pressure is sufficient; - the boiler is powered electrically; - the gas is distributed.
