Carbon monoxide
testing courses
for Victorian
plumbers
By Enzo Alfonsetti, Manager, Type A
Gas Appliance and Component Safety
Master Plumbers, in partnership with
Energy Safe Victoria and the Victorian
Building Authority, is pleased to present
Carbon Monoxide testing courses for
Victorian plumbers.
The training course will provide Victorian
plumbers with the skills and knowledge to use
carbon monoxide (CO) testing equipment and
complete the practical procedure to test gas
appliances for CO emissions.
The course will cover the process you
should follow to identify situations that could
result in CO spillage within a residence.
Gas Technical Information Sheets
The courses will reference the following

Using hose assemblies
in commercial kitchens
By Jason Treseder, Senior Gas Engineer
The most frequent, non-compliance issue we
find during commercial kitchen inspections
involves using hose assemblies to connect
appliances.
While working with Standards Australia to
amend AS/NZS 5601.1:2013 Part 1 to provide
clearer guidance, ESV is also providing its
interpretation of commercial kitchen installation
requirements. This includes the requirement
to buffer an appliance and using a restraint to
limit how much it can move. Listed below are
a number of our quick guides.
Appliances on castors, rollers or wheels
Any appliance on castors, rollers or wheels
must be:
» » connected to a consumer pipe with a hose
assembly
» » able to be isolated and disconnected from
the consumer pipe isolation valve
» » attached to a wall with a restraint shorter than
the hose assembly and strong enough to hold

This is a timely reminder to all gasfitters that
when being called out to complete a service
on any open flue gas heater, you ensure
that as part of the service you follow the
abovementioned sheets, particularly No. 38.

Installing a buffer (or spacer) behind an
appliance helps prevent strain, abrasion or kinking
when the appliance is moved back into position.
Given the mobility of the appliance, ensuring
that nearby combustibles are protected or
manufacturer’s clearances are maintained is a
must that may also require the use of buffers.
it, without breaking or the hose assembly
being damaged if the appliance is moved.
Connecting hose assemblies
A hose assembly should be as short as
practicable and must not be exposed to higher
temperatures than the hose manufacturer’s
specified maximum, or subjected to strain,
abrasion, or kinking when the appliance is
moved in or out of position.
At the inlet end, the hose assembly’s
connection can be a manual shut-off valve and
union, or a quick-connect device that automatically
shuts off the gas when disconnected.
However, it must be a manual shut-off valve
if a quick-connect is fitted at the appliance end.
Important notes about restraints and buffers
A restraint (a chain or cable) must be short
enough to ensure the hose is not subjected to
strain or kinking when the appliance is moved.
A restraint should also be used when the
appliance regulator cannot be accessed without
moving the appliance.
Compliant example: ensure cleareance between
a hose assembly’s bottom loop and the floor,
it must be at least 50mm.
