Commercial Kitchens - Gas Installations Updated for 5601.1 2022

This instructional video covers the
various Australian standards and energy
safe Victoria gas information sheets you 
may need to consider when undertaking a
commercial kitchen installation. 

it is intended to provide general information
and guidance about the applicable
Australian standards you will need to be
familiar with when installing commercial
kitchen appliances; it is not intended to
provide comprehensive instructions on
how to complete an installation 

the applicable Australian standard is as/nzs 
5601.1 2022. the video will cover the
most important aspects of a commercial
kitchen installation 

from the perspective of this standard it will
also consider installation issues that
are most commonly the subject of
non-compliance when an installation is
inspected by Energy safe Victoria. 

the relevant Clauses covering each stage of
a kitchen installation are also featured.

standard gas installations require you
to lodge a compliance certificate with
the Victorian building authority. 

complex gas installations require you to seek
acceptance from Energy safe Victoria.

prior to commissioning you must also
submit a signed schedule 11 when you
complete the work whether it's LPG or
Natural Gas. Energy safe Victoria's
acceptance of a completed installation
is required before you can connect to
the gas supply. Energy Safe Victoria's
gas information sheet 33 will help you
identify if the installation is a
standard or a complex one.

first consider if the kitchen's
ventilation is adequate. the amount of
ventilation required depends on the type
and number of gas appliances to be
installed. this requirement is covered by
Clause 6.4 it discusses the adequacy and
quality of the Air Supply and measures
needed to ensure an adequate supply of
fresh air is available to the kitchen's
Gas Appliances inside the kitchen.

various standards apply to the
installation and connection of the
appliances. Clause 5.2.9.2 now requires the installation of
either a quarter turn isolation valve or emergency stop button and solenoid with
pressure proving where more than one commercial catering Appliance is to be
connected in the kitchen. signage clearly identifying the isolation point will
also be required. an isolation valve must connect gas appliances in a commercial
kitchen. this requirement is covered by Clauses 6.6.3 and 6.6.4 4 which discuss the
means and type of isolation to use. 

it will normally comprise a manual shut off
valve. this valve must be accessible at all times. Clause 1.3.1 defines what accessible means.

combustible walls around your gas appliances must be protected with an
approved type of facing board.  Clause 6.2.5 describes the temperature nearby
combustible surfaces are allowed to reach. 

appendix C defines the approved types of fire resistant or non-combustible material, 
various methods available to protect combustible surfaces and the specifications of fire
resistant material must meet for appliances installed on a combustible surface such as Timber floors 

refer to Clause 6.10.2.4 other aspects of the installation you must consider 

the clearance between the gas appliances and the wall behind them is important for
two main reasons - first if the installation is against an unprotected combustible wall the clearance must meet
the manufacturer's installation instructions as per Clause 6.2.2.
secondly clearance is required to avoid crushing any gas components located behind the appliance a bumper the same size or greater than the required clearance must be installed to maintain the clearance at all times. 

this is required regardless of whether the appliance is on wheels or casters and designed to be moved or if it is on legs
the minimum clearance between a gas Appliance and the extraction system's grease filter is specified in Clause
6.10.2.2 this can range from 200 millimeters for a kebab cooker to 1350 millimeters for a Target top Chinese
cooking table griddle barbecue, Char griller, Broiler or open top flare griller Broiler the minimum distance
between different gas appliances and the grease filter vary depending on the type of gas Appliance being installed. 
refer to Clause 6.10.2.2 if you are unsure sure of the minimum clearance for each Appliance. it is also important to double check the
installation instructions what's happening behind the appliance before it's installed 

there is a standard for every aspect of the plumbing fixtures fitted to support the appliances installation 

Appliance isolation is governed by clause 6.6.3 and must be accessible and able to be isolated if a hose assembly is used
to connect a gas Appliance the isolation must be located. 

in accordance with Clause 5.9.6 the hose assembly must be installed forming a u-shape and be free from any kinks or permanent deformation 

in accordance with clause 6.10.2.7 in commercial kitchen installations semi-rigid connectors can only be used in accordance with clause 6.10.2.8 

in accordance with Clause 5.9.1 the hose must be one continuous length and the clearance between the hose assembly's bottom Loop and the
floor must be at least 50 millimeters 

an appliance regulator must be fitted to each Appliance as per Clause 6.6.5. it must be installed as close as practicable to the Appliance and be
accessible for servicing and adjustment

in accordance with Clause 6.2.14 a restraint must be fitted if an appliance is connected by a hose assembly and it is more than 20
kilograms and fitted with casters rollers or wheels or can be slid out for servicing the restraint which is attached to the wall must be shorter
than the hose assembly and strong enough to not break when the appliance is moved. a bumper must be fitted to ensure the
minimum clearance between the appliance and the wall behind it is maintained at all times and to ensure the hose assembly is not damaged when the
appliance is moved back into position against the wall. this is a requirement regardless us of whether the appliance is on wheels or casters and designed to be moved or whether it is on legs fittings installed on Appliance is designed to be moved for cleaning must meet various standards in accordance with clause 6.2.13 a hose assembly must be used to connect an appliance fitted with casters rollers or Wheels.

in accordance with Clause 6.10.2.6 freestanding commercial catering equipment with a connection Point under the equipment must not use a hose assembly to connect to that point. a gas Appliance designed to be moved can only be connected to the consumer piping using a hose assembly as per Clauses 5.3.7, 5.9.5, 5.9.6, 6.10.2.7, 6.2.13 and 6.2.14. the clearance between the bottom Loop and the floor must be at least 50 millimeters. 

if an appliance weighs more than 20 kilograms an appliance restraint must be fitted. it must be shorter than the hose assembly
and strong enough to not break when the appliance is moved. 

as required by clause 6.2.14 note the position of the valve and other components behind the appliance if the appliance can be moved
this installation will be considered to be compliant. a bumper must be fitted between the appliance and the wall behind it to ensure the minimum
clearance is maintained and to make sure that components behind the assembly are not bumped kinked or damaged in any way when the appliance is back against the wall 

in accordance with Clause's 6.2.2 6.2.5 and 6.10.2.3 there must be clearances on either side of the appliance and between the appliance and any benches or other appliances installed beside it. refer to the manufacturer's installation instructions clearances must either meet the manufacturer's installation instructions, be sufficient to avoid nearby surfaces getting hotter than 65 degrees Celsius or comply with the
specifications of clause 6.10.2.3 for minimum clearances around cooking surface areas avoiding the use of combustible materials in benches is a
key requirement in a commercial kitchen installation non-combustible bench materials enable an efficient use of space as zero clearances to appliances are often allowable depending on the appliance manufacturer's requirements and they do not present a fire risk. 

ensuring each stage of a job complies with the relevant Australian standard is the most cost effective approach to a commercial kitchen installation and the safest rework to meet the standards compliance requirements will cost you time and money and you may incur a fine
from Energy safe Victoria if your work fails more than one inspection. even greater cost may be to your business when loss of reputation is considered. 

by following these guidelines and improving your knowledge of the applicable Australian standards, your installation is more likely to be deemed compliant on first inspection.
