O N L I N E V E R S I O N J Section 0: General guidance Introduction to the provisions 0.1 This Approved Document gives guidance on how to satisfy the requirements of Part J. Although Part J applies to the accommodation of any combustion installation and liquid fuel storage system within the Limits on Application, the guidance in this Approved Document has been prepared mainly with domestic installations in mind, such as those comprising space and water heating systems and cookers and their flues, and their attendant oil and liquefied petroleum gas (LPG) fuel storage systems.
Part J does not include specific provisions relating to the storage of solid fuel (including solid biofuel) but the relevant guidance in Approved Document B should be followed. 2. A balanced compartment is a method of installing an open-flued appliance into a compartment which is sealed from the remainder of the building and whose ventilation is so arranged in conjunction with the appliance flue as to achieve a balanced flue effect. 3.
A balanced flue appliance is a type of room- sealed appliance which draws its combustion air from a point outside the building adjacent to the point at which the combustion products are discharged, the inlet and outlet being so disposed that wind effects are substantially balanced. Balanced flues may run vertically, but in the most common configuration they discharge horizontally through the external wall against which the appliance is situated. 0.2 The guidance applies to combustion installations having power ratings and fuel storage capacities up to the limits shown in a) to c) below. Guidance which applies generally is given in this section and Section 1.
More specific guidance is then given in: 4. The boundary is the boundary of the land or buildings belonging to and under the control of the building owner. Depending upon the paragraphs of this Approved Document to which it applies, it may be drawn only around the perimeter of the land in question or extended to the centreline of adjacent routes or waterways as shown in Diagram 1. a. Section 2 for solid fuel installations of up to 45kW rated output; b. Section 3 for gas installations of up to 70kW c. Section 4 for oil installations of up to 45kW net (77.7kW gross) rated input; Diagram 1 Boundaries in this Approved Document rated heat output .
Section 5 gives guidance on requirement J5 for heating oil storage installations with capacities up to 3500 litres and LPG storage installations with capacities up to 1.1 tonne, although there is no size limit on the application of requirement J5. Section 5 also gives guidance on requirement J6, which is limited to installations where the capacity of the oil storage tank is 3500 litres or less, serving buildings used wholly or mainly as private dwellings. 0.3 For installations subject to the requirements of part J but outside the scope of this Approved Document, such as incinerators or installations with higher ratings than those mentioned above, specialist guidance may be necessary.
However, some larger installations may be shown to comply by adopting the relevant recommendations to be found in the CIBSE Guide B and practice standards produced by BSI and IGEM. Explanation of terms used 0.4 The following definitions have been adopted solely for the purposes of providing clarity in this Approved Document. 5. A Building Control Body is a body that carries out checks for compliance with the Building Regulations on plans of building work and on the building work itself. The Building Control Body may be either the local authority or an Approved Inspector. For further details, see the manual to the Building Regulations. 1.
An appliance compartment is an enclosure specifically constructed or adapted to accommodate one or more combustion appliances. 6. The capacity of an oil tank is its nominal capacity as stated by the manufacturer. It is usually 95 per cent of the volume of liquid required to fill it to the brim. 10 Combustion appliances and fuel storage systems Approved Document J O N L I N E V E R S I O N
