BS5410:1 1997
Code of Practice for Oil Firing
Part 1: Installations up to 45 kW output capacity for space heating and hot water supply purposes


The text herein is not a a full reproduction of the British Standard. It is summary based upon interpretation of the original text and not intended as a replacement for the full text. It should be used for general guidance only.

Minimum recommendations for the installation of all types of oil burning equipment are required so that equipment manufacturers, suppliers, installers and users may have a common basis on which to work. This is a summary of the British Standard which is presented as a Code of Practice but it should be considered as specification requirements. 

Part 1 of BS5410 covers oil burning installations up to 45 kW output capacity for space heating and hot water supply purposes and associated oil tanks of capacity up to 3 500 l. They are typically intended to be used in a family home or other building of similar scale for example a farm house or small farm building. The code can also be of guidance in the installation and operation of oil fired cookers, with or without boilers.

Liquid fuels

  • Standard grade kerosene (class C2) and industrial gas oil (class D) should be used in oil fired appliances.
  • Standard grade kerosene, known as 28 second burning oil, should be used for domestic heating.

Appliances and burners

  • Appliances described in this standard include freestanding, wall mounted and hearth type heating and combination boilers.
  • They are designed to be connected to a flue pipe, chimney or integral flue discharging flue gas into the open air.
  • Heating boilers, cookers and burner types are described in the full standard.

Installation of oil fired appliances

  • The location of the appliance and its method of installation will depend on the disposition of the outlets from it, a tidy layout of pipes, cables and ductwork, connection to a satisfactory flue and provision of combustion and ventilation air. Installation work should be undertaken by competent technicians.
  • Factors affecting selection are described in the full standard.
  • The siting of the appliance should be undertaken with great care to reduce hazards such as fire risk to a minimum.
  • Provision of air for combustion and ventilation should be considered.
  • Protection from freezing and corrosion are required.
  • For open vented systems, an open safety vent pipe should be provided. For sealed systems an expansion vessel should be provided.
  • A safety valve is not necessary for an open vented system, but a safety valve should be fitted in a sealed system.
  • If it is not possible to install the appliance at ground floor or basement level, preferably in a kitchen or utility area or the heating appliance room, some alternative types of installation can be considered. Special specifications for those housed in airing cupboards, understairs cupboards, fireplaces, bathrooms, bedrooms, siting rooms, garages and roof spaces are given in the full standard.
  • Special specifications for external installations are given in the full standard.

Oil storage tanks and equipment

  • Storage tanks should be made of carbon steel, pressed sectional steel, medium density polyethylene or glass reinforced plastic. Sectional tanks should only be used where there is no alternative.
  • The minimum net capacity of oil storage tanks should be not less than 1 250 l and should also be sufficient to accommodate the usual quantity ordered with a two week reserve.
  • The type of oil level indicator used will depend on the accuracy required.
  • It is recommended that an overfilling alarm system be installed on tanks.
  • Filling pipes should be in accordance with BS 799:5.

The full standard also includes information on:

  • Oil storage tanks and equipment
  • Accommodation for oil storage tanks for single family dwellings
  • Tank installations
  • Oil system for storage tank to burner
  • Flues and chimneys - specifications and installation
  • Room sealed appliances
  • Electrical and control recommendations
  • Commissioning
  • Maintenance
  • Refurbishment and conversions of existing appliances.

A British Standard nor this summary does not, necessarily, include all the necessary information for correct implementation of the Standard to any specific application. This is purely the responsibility of the user. Standards are updated by either amendment or revision. Users should ensure that they are using the latest version.
