SHOULD YOU MOVE HOUSE, PLEASE HAND THEM OVER TO THE NEXT OCCUPIER. 1. Introduction The Halogen Boiler is a wall-mounted appliance, suitable for installation onto small sealed heating systems. It incorporates all the components for sealed system requirements, these include, pressure gauge, pressure relief valve, expansion vessel, circulating pump and manual reset overheat thermostat. A manual air vent is also located on the appliance. There are two controls on the appliance, one adjusts the water flow temperature, and the other is an on/off switch. A 2 m long electrical flex with integral plug enables the appliance to be connected into a standard 13A ring main socket or via the 24 hour plug in timer supplied. 2.

Installation Requirements Statutory Requirements The installation should also be in accordance with the relevant recommendations in the current editions of the following British Standards: BS 7074: Pt 1 Expansion vessels and ancillary equipment for sealed water systems BS 5449 Forced circulation hot water systems for domestic premises BS 7671 Requirements for Electrical Installations. IEE Wiring Regulations. BS 4814 Expansion Vessels using an internal diaphragm for sealed hot water systems. BS 6798 Installation of gas fired boilers of rated input not exceeding 70 kW Net. BS 6759: Pt 1 Safety valves BS 1362 General purpose fuse links for domestic & similar purposes. (Primarily for use in plugs). BS 5376 Code of Practice for selection & installation of gas space heating Boiler Location The boiler is not suitable for external installation. The position selected must be within the building unless protected by a suitable enclosure. There must be adequate space for installation, servicing and operation of the boiler as well as adequate air circulation. Page 3 of 13 If the boiler is to be placed in a cupboard this cupboard should not be used as a storage cupboard. Ventilation should be provided as detailed below. Ventilation This boiler does not require a purpose provided air ventilation in the room, however it does require room air to circulate through the boiler to ensure the convection heat output performance is maintained. If the boiler is installed in an enclosure or small cupboard, there must be an equivalent ventilation free area in the enclosure or small cupboard to that of the boiler. Upper Ventilation Free Area These should be the same or larger than in the appliance case mm2 Lower Ventilation Free Area As above Electrical Supply This appliance must be earthed The appliance is supplied with a 2 m electrical flex with integral fused plug, which requires a standard 220 240V ~ 50Hz supply via a normal ring main socket. If required, the plug connection can be made via the 24 hour plug in timer supplied. All fuses must be ASTA approved to BS 1362 In the event of an electrical fault after installation of the boiler, preliminary electrical system checks must be carried out. i.e. earth continuity, short circuit, polarity and resistance to earth. Central Heating Systems This boiler is designed specifically for use in small, pressuris ed, sealed system installations. The installation must comply with BS 6798. Safety Valve – The safety valve, which is pre-set at a maximum of 3 bar is an integral part of the boiler and cannot be adjusted. Its relief outlet must be piped to a suitable outside position. Pressure Gauge This indicates the system fill pressure. It will show a higher pressure when the system is hot. Circulating Pump The circulating pump is located inside the boiler case. Its performance is suitable for all systems to which the boiler should be connected. Expansion Vessel The expansion vessel, which is located inside the boiler case, has a capacity of 2.0 L, with a pre -charge of 0.5 bar. The maximum heating system water content using this integral expansion vessel is 2 4.0 L. This is with a cold fill of 0.5 bar. Should the system volume be in excess of that specified, a second expansion vessel must be connected to the heating system. BS 5449 gives further guidance for expansion vessel sizing.
