Instructions for the installer
11.INSTALLATION
The appliance connection point shall be accessible with the appliance installed.
11.1 Clearances above and around domestic appliances
Extract from AS5601
REQUIREMENTS
1 Overhead clearances – (Measurement A) Range hoods and exhaust fans shall be installed in
accordance with the manufacturer’s instructions. However, in no case shall the clearance between
the highest part of the hob of the cooking appliance and a range hood be less than 600 mm or, for an
overhead exhaust fan, 750 mm. Any other downward facing combustible surface less than 600 mm
above the highest part of the hob shall be protected for the full width and depth of the cooking surface
area in accordance with Clause 5.12.1.2. However, in no case shall this clearance to any surface be
less than 450 mm.
2 Side clearances – (Measurements B & C) Where B, measured from the periphery of the nearest
burner to any vertical combustible surface, is less than 200 mm, the surface shall be protected in
accordance with Clause 5.12.1.2 to a height C of not less than 150 mm above the hob for the full
dimension (width or depth) of the cooking surface area. Where the cooking appliance is fitted with a
‘splashback’, protection of the rear wall is not required.
3 Additional requirements for Freestanding and Elevated Cooking Appliaces – (Measurements
D & E) Where D, the distance from the periphery of the nearest burner to a horizontal combustible
surface is less than 200 mm, then E shall be 10 mm or more, or the horizontal surface shall be above
the trivet. See insets above.
NOTES
1 Requirement 3 does not apply to a freestanding or elevated cooking appliance which is designed to
prevent flames or the cooking vessels from extending beyond the periphery of the appliance.
2 The ‘cooking surface area’ is defined as that part of the appliance where cooking normally takes
place and does not include those parts of the appliance containing control knobs.
3 For definition of hob, see Clause 1.4.64.
4 For definition of trivet, see Clause 1.4.109.
5 Consideration is to be given to window treatments when located near cooking appliances. See
Clause 5.3.4.
11.2 Combustion gas discharge
Combustion gases may be discharged by means of hoods connected to a flue with reliable natural
draught, or a fan extraction system. An effective extraction system requires careful design by an
authorised specialist, and must comply with the regulation distances and positions. After installation, the
engineer must issue a certificate of compliance.
