INSTALLATION INSTRUCTIONS_ GENERAL INSTALLATION REQUIREMENTS GAS SAFETY It is the law that all gas appliances are installed by a CORGI registered installer (you can check this by contacting corgi on 01256.372200) in accordance with the regulations listed below. Failure to install appliances correctly could lead to prosecution. It is in your own interest and that of safety to ensure that the law is complied with.
INSTALLATION INSTRUCTIONS_ FLUE POSITION IMPORTANT: THE FLUE SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH THE RECOMMENDATIONS CONTAINED IN BS 5440:1. The boiler MUST be installed so that the terminal is exposed to the external air. It is important that the position of the terminal allows free passage of air across it at all times. If the terminal discharges into a pathway or passageway check that combustion products will not cause nuisance and that the terminal will not obstruct the passageway.
INSTALLATION INSTRUCTIONS_ CENTRAL HEATING SYSTEM -Fig. 1 The boiler is designed for use in a sealed central heating system in accordance with the requirements of BS 5449 and BS 6798. The system should be designed to operate with flow temperatures of up to 82°C. When designing the system, the pump head, expansion vessel size, mean radiator temperature, etc. must all be taken into account. Refer to the pump performance table for guidelines.
INSTALLATION INSTRUCTIONS_ CONDENSATE DRAIN Termination to an internal soil and vent pipe FAILURE TO INSTALL THE CONDENSATE DISCHARGE PIPEWORK CORRECTLY WILL AFFECT THE RELIABLE OPERATION OF THE BOILER The condensate discharge pipe MUST NOT RISE at any point along its length. There MUST be a fall of AT LEAST 2.5° (50mm per metre) along the entire run. Boiler 50m m per m etre o 2 .5 ° M f p ip e inim um run fall I.
INSTALLATION INSTRUCTIONS_ BOILER INSTALLATION MINIMUM DISTANCES FOR FIXING TO WALL To allow access in the boiler for maintenance operations, the minimum distances shown below must be respected (fig. 1): To facilitate installation, the boiler is supplied with a template for advance location of connections to pipes. In this way, you may simply hook up the boiler when wall work is completed. 60 S MINIMUM DISTANCE mm. Fig.
INSTALLATION INSTRUCTIONS_ ANTI-FREEZE SYSTEM ANTI-FROST SYSTEM Radiant boilers are equipped with an AntiFreeze system which comes into operation when the temperature falls to 5° C (Heating sensor) and 4° C (Hot water sensor). To protect the internal Radiators, a room thermostat or remote control must be fitted.
INSTALLATION INSTRUCTIONS_ ELECTRICAL CONNECTIONS For qualified personnel only: the boiler works with 230 V 50 Hz AC current and has maximum input of 170 W. Connection to the electrical mains must be performed with a device having an omnipolar opening of at least 3 mm. Make sure the live and neutral connections conform to the diagram. A secure earth connection is compulsory according to national and local ragulations.
