| 1.12 Boiler Clearances Refer to diagram 1.3. This boiler must be positioned so that at least the minimum operational and servicing clearances are provided. Additional clearances may be required for installation. If fixtures are positioned next to the boiler they should be made removable for access to pipework. At least a minimum clearance of 500mm must be left in front of the boiler for servicing, see diagram 1.3. 1.13 Room Ventilation The boiler is room sealed and does not require the room or space containing it to have permanent air vents. 1.14 Boilers in a Compartment Where the installation of the boiler will be in an unusual position, special requirements are needed, the current issue of BS6798 gives detailed guidance on these requirements. A compartment used to enclose the boiler must be designed and constructed specifically for this purpose. An existing cupboard or compartment modified for the purpose may be used. Details of essential requirements for cupboard or compartment design are given in the current issue of BS6798. The doorway opening should be of sufficient size to allow for easy removal of the boiler. Where the boiler is fitted in a cupboard or compartment, permanent high and low level ventilation must be provided. The minimum ventilation areas required are given in Table 2. 1.15 Timber Frame Building If the boiler is to be installed in a timber frame building it should be fitted in accordance with the Institute of Gas Engineers document IGE/UP/7/1998. If in doubt seek advice from the local gas undertaking or Hepworth Heating Ltd. 1.16 Heating System Controls The heating system should have installed: a programmer and room thermostat controlling the boiler. Thermostatic radiator valves maybe installed, however they must not be fitted in a room where the room thermostat is located.
