Resumen del manual
Location of Boiler The installation of the 1001 must be on a suitable non-combustible load bearing wall which will provide an adequate fixing for the boiler mounting bracket assembly. The location should be in an area where the water pipes will not be subjected to frost conditions. In siting the combination boiler the following limitations must be observed: The combination boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the current, i.e. wiring regulations and in Scotland the electrical provisions of the building regulations applicable in Scotland, with respect to the installation of the combination boiler in a room or internal space containing a bath or shower. Where a room sealed appliance is installed in a room containing a bath or shower any electrical switch or appliance control utilising mains electricity, should be so situated that it cannot be touched by a person using the bath or shower. Terminal Position POSITION MINIMUM SPACING (fig. 3) mm A Directly below an openable window, air vent, or any other ventilation opening 300 B Below gutters, soil pipes or drainpipes 75 C Below Eaves 100 D Below a Balcony 100 E From vertical drainpipes or soilpipes 75 F From internal or external corners 100 G Above adjacent ground or balcony level 100 H From a surface facing the terminal 600 I Facing another terminal 1,200 J From opening (door/window) in carport into dwelling 1,200 K Vertically from a terminal on the same wall 300 L Horizontally from a terminal on the same wall 300 N Below carport 600 A Quinnel Barrat and Quinnel guard (part. No. C2) should be screwed to the wall centrally over the terminal, when the distance is less than 2 m from the outside floor. Air Supply The room, cupboard or compartment in which the boiler is installed does not require a purpose provided vent. 1001 Terminal Position Fig. 3 Minimum Clearance mm Fig. 5 NOTES * Access to the front of the boiler must be available for maintenance (min. 600 mm). 1001 Flue system The boiler allows the flue outlet to be taken from the rear of the boiler or from either side. A standard flue length of 0.75 metres is provided. Alternative lengths of two or three metres can be supplied (equivalent to wall thicknesses of up to 565, 1815 and 2815 mm for rear flues and deduct 91 mm plus distance from side wall for side outlet flues). It is absolutely essential, to ensure that products of combustion discharging from the terminal cannot re-enter the building, or enter any adjacent building, through ventilators, windows, doors, natural air infiltration, or forced ventilation/ air conditioning. Gas Supply If necessary the local Gas Region should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas. An existing service pipe must not be used without prior consultation with the Local Gas Region. A gas meter can only be connected by the Local Gas Region, or by a Local Gas Region's Contractor. Installation pipes should be fitted in accordance with BS6891-1988. Appliance inlet working pressure must be 20 mbar MINIMUM. Pipework from the meter to the combination boiler must be of an adequate size. The boiler requires 3.3 m3/h (116 ft3/h) of natural gas. Do not use pipes of a smaller size than the combination boiler inlet gas connection. The complete installation must be tested for gas soundness and purged as described in BS6981-1988. All pipework must be adequately supported. An isolating gas valve is provided and should be fitted on the manifold assembly. Water System Central Heating It must be a sealed system. Detailed recommendations are given in BS6798, BS5449, BS6700 and CP342 Part. 2. Pipework not forming part of the useful heating surface should be insulated to prevent any heat losses or possible freezing (i.e. in roof spaces or ventilated underfloor spaces). Drain taps should be positioned at the lowest point of the system in accessible locations to permit the whole system to be drained down. The drain taps should be in accordance with BS2879. Copper tubing to BS2871, Part. 1 is recommended for water carrying pipework. Pipework in horizontal runs should have a gradient where possible to facilitate the removal of air. It should be ensured that the boiler heat exchanger is not a natural point for collecting air. A typical heating system with domestic hot water circuit is illustrated in fig. 6. Important -A bypass must be fitted to ensure a minimum flow rate through the boiler of 6 l/min. The bypass should be fitted as far as possible from the boiler if thermostatic radiator valves are fitted throughout. Make up Water Provision must be made for replacing water lost from sealed system. Reference should be made to BS6798, for methods of filling and making up sealed systems. There must be no direct connection between the boiler's central heating system and the mains water supply. The use of mains water to charge and pressurise the syste...
