1 General
1.5 Gas Supply
The gas installation must be in accordance with the current issue of BS6891.
The supply from the governed meter must be of adequate size to provide a steady inlet working pressure of 20mbar (8in wg) at the boiler.
On completion, test the gas installation for soundness using the pressure drop method and a suitable leak detection fluid, purge in accordance with the above standard.
1.6 Electrical Supply
WARNING. This boiler must be earthed.
All system components shall be of the approved type and be wired and connected in accordance with the requirements of the current issue of BS7671 and any applicable local regulations.
Connection of the boiler and system controls to the mains supply must be through a common isolator and must be fused 3A maximum. This method of connection should be, preferably, by a double pole isolating switch, provided it has a minimum contact separation of 3mm on both poles. This should be readily accessible and preferably adjacent to the appliance. It should supply the appliance only and be easily identifiable as so doing.
Alternatively, an unswitched shuttered socket outlet and 3A fused 3 pin plug both to the current issue of BS1363 may be used, provided that they are not used in a room containing a bath or shower.
Wiring to the boiler must be PVC insulated type to the current issue of BS6500 Table 16.
1.7 Condensate
The boiler condensate should, if possible, be discharged into the household internal draining system, that is, sink or washing machine drain. If this is not practicable, discharge can be external, into the household drainage system or a purpose designed soakaway
The boiler is fitted with a safety device to prevent the boiler from working if the condensate pipe gets blocked by either ice or debris.
It is, therefore, recommended that any external condensate drain pipe is insulated to prevent it freezing up.
Alternatively, a larger diameter pipe can be used and insulated.
The condensate drain pipe should be checked during any servicing and any debris found removed.
Refer to the British Gas publication “Guidance Note for the Installation of Domestic Condensing Boilers” for further information.
1.8 Heating System Controls
The heating system should have installed: a programmer and room thermostat controlling the boiler.
Thermostatic radiator valves may be installed in addition to the room thermostat.
Note: For further information, see The Building Regulations 1991 - Conservation of fuel and power, 1995 edition - Appendix G, table 4b.
