B+S NC Series - Combustible Surfaces

7
The appliance shall be installed with an exhaust system comprising a hood and duct system. The hood shall be made
of a material which is impervious to fat, grease and vapour. It shall be constructed so it can be readily and efficiently
cleaned. Its inside faces shall be smooth and free of obstructions and all joints shall be grease tight.
The hood shall be located so as to effectively ventilate the noodle cooker and shall extend at least 150 mm beyond
the perimeter of the unit. The exhaust duct system shall be adequately sized and shall not get connected to any
other ventilating or exhaust system.
As suitable grease trap shall be provided to prevent grease vapour entering the exhaust system and shall be located
to avoid constituting a fire hazard and be readily accessible for regular cleaning.
(please refer to AS/NZS 5601 clause 6.10.2.2 to verify clearances for ventilation.)
B&S units can be installed in a domestic environment provided the installation is strictly in accordance with
the manufacturer’s instructions and as per the AS/NZS5601.1 (please refer to the latest version when
released). The installation of the unit must comply with clauses 6.2.4, 6.10.2 and 6.10.1.15 and an exhaust
system shall be installed according to AS1668.1 and AS1668.2 interlocked to the gas supply. B&S shall not
be responsible for any unauthorized and/or non-compliant installations and will void the warranty.
Combustible Surfaces
Clearances to combustible surfaces must be in accordance with AS/NZ 5601- Gas Installations, clause 5.12.4.5.
Install on a flat/level, solid, fire resistance floor. Where the floor is not fire resistant, a fire resistant material shall be put
under the appliance which shall have a fire resistance rating at least equal to that of 10mm millboard. The material
shall extend at least 50mm beyond the edge of the appliance.
Leave a clearance of at least 200mm between the appliance and any combustible surface.
Leave clearance of at least 500mm from the front of the noodle cooker for services.
Please refer to table 6.9 and 6.10 in AS 5601.1. clause 6.10.2.2 and 6.10.2.3. Table 6.10 (2013 version) is given
below. (Please refer to the latest version when released)
MINIMUM CLEARANCE AROUND COOKING SURFACE AREA
The clearance to combustible surfaces from commercial catering equipment shall be as specified in the appliance
manufacturer’s instructions and shall not be less than the clearance specified in the table below.
Cooking surface area
Minimum clearance in mm
A
Above the cooking surface of a gas appliance
600
B
Subject to C from a cooking surface area having an open
flame cooking appliance and no means of preventing
cooking vessels from overhanging the edge of the gas
appliance
250
C
From the side of a cooking appliance where the
combustible surface is at least 100mm below a cooking
surface area
50
D
From a gas appliance flue way or rear of the gas appliance
with a splashback
50
E
From the rear or side of a gas appliance which is not an
open flame gas cooking appliance
50
Notes:
1. The cooking surface area is defined as being that part of the gas appliance where cooking normally takes
place and does not include those parts of the gas appliance containing control knobs.
2. These clearances do not apply where an adjacent surface is of a non-combustible material or is combustible
but protected with a fire-resistant material. The fire-resistant material may be covered by ceramic tiles or
stainless steel to meet appropriate requirements relating to health protection.
3. Care should be taken where a combustible surface is covered by a non-combustible material for example,
covering a combustible surface with stainless steel will not prevent heat transfer, and in some circumstances
hazardous situation could arise.
