Page 15: General Installation Requirements
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. - Page 16 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.
- Page 17 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.
