• A set of water inlet and outlet and gas inlet accessories, which make it easier to connect the heater to the main water and gas supplies. OPERATION Once the appliance has been turned on following the indications given in section A.2.3. “Instructions for starting up the appliance” gas is supplied to the burner whenever a hot water tap is turned on.
• COMBUSTION GAS REMOVAL Flue: A draught diverter is fitted to the top of the water heater. The nominal flue size is 90 mm. (D61B, D61E) and 110 mm. (G11E). In exposed situations, twinwalled flue pipe should be used. A minimum length of vertically rising flue of 600 mm. must be provided to ensure the water heater’s produts of combustion are completely evacuated. If single wall flue pipe is being used which has to pass through combustible materials, provide a metal sleeve of 115 mm.
Fixed ventilation should be provided to avoid draughts as far as possible without impairing the free area of ventilation, even in adverse weather conditions. All permanent openings for ventilation should be designed to prevent the entry of vermin. Where screens are provided, they should not have apertures of less than 6 mm. or greater than 9 mm. in any direction, and they should be accessible for cleaning. Fine mesh screens should be avoided as they are liable to become blocked with dust.
