5.2 Selection of appliance
5.2.1 Factors affecting selection
NOTE The servE ceabilit’ and safety of a heating appliance depend upon careful selection to enable It to match its working environment as well as the characteristics of the appliance itself
The manner In which appliances are used varies from building to building and this should be taken into account when a heating appliance is selected. The operating factors listed in 5.2.2 should be ascertained and used In the selection of the appliance.
5.2.2 Operating factors
5.2.2.1 The required gross capacity of the heating appliance should be determined on the basis of the following factors
a) the preferred room temperature;
b) the design winter temperature;
c) the structural and ventilation heat losses per °C;
d) the degree of continuity of heating required by the user;
e) the extent to which space and water heating are to be coupled; and
1) the preferred form of user control or programming.
5.2.2.2 The rated output of the appliance should he able to meet the calculated space and water heating demand.
NOTE correct selection of system controls can avoid the need for a margin of extra capacity.
5.2.2.3 The low load requirements of the system should also be taken into account, particularly when space and water heating are to be combined.
NOTE 1 Where these requirements are likely to be exceeded at the lowest limit of the turn down run,gc of an appliance then a multi stage burner and controls is preferred.
NOTE 2 Guidance on the design of space and water heating systems is gEver in BS EN 12828 and the CIBSE Domestic Heating – Design Guide IN I.
5.2.2.4 Heating systems served by fully automatic liquid fuel fired appliances should be of the fully pumped circulation type with their electrical controls arranged to prevent the burner short cycling. NOTE Attention is drawn to the Building Regulations f4J. (51.161 with regard to heating system control.
5.3 Siting of appliance
5.3.1 General
The appliance should be sited so as to reduce risks, especially the risk of fire, to a minimum. If possible, the appliance should be installed at ground floor or basement level, preferably in a boiler room, utility area or kitchen. The appliance should be Installed on a floor or above a surface which is impervious to liquid fuel. Minor spillages from the burner or its connections occurring during installation or maintenance should be contained within the appliance or within a separate containment tray. The appliance should not be positioned where accidental spillage would be able to soak into combustible material such as wood or carpeting. Fuel pipework within the building or structure should be kept to a minimum.
NOTE 1 Alternatively, floor standing or wall mounted appliances designed specifically for external locations may be installed.
Where a liquid fuelled appliance is located inside a building or structure or within a restricted area externally, a carbon monoxide detector alarm conforming to HS EN 50291.1 should be installed in accordance with the manufacturer’s instructions.
The need to avoid noise and vibration nuisance to building occupants and neighbours should be taken into account.
The following should also be taken into account:
a) any constraint imposed under 5.2.2:
b) the manufacturer’s installation instructions with respect to the provision of space around the appliance to allow:
1) sufficient circulation of air for combustion and cooling and the operation of a draught diverter if required;
2) sufficient access and clearance for maintenance and servicing (see also 5.6.10);
c) environmental conditions, and need for combustion and ventilation air in accordance with 5.4;
d) heat emission from the appliance casing and the manufacturer’s instructions with respect to provision of protei-tion of the floor or wall on which the appliance is to be mounted;
e) the recommendations given in Clause 10 regarding flues and chimneys: and
f) the fact that open-Hued appliances should not be installed in bathrooms, bedrooms or bedsitting rooms because of the possible increased risk of carbon monoxide poisoning.
NOTE 3 ThepI size of the appliance might determine whether it can be accommodated in a habitable room or whether gt needs to be separately housed.
If an appliance is intended to be built-in, so that it is adjacent to combustible material, an appliance classified as suitable for this purpose should be selected.
