Exclusions and Design Requirements for Eligibility Under the Scheme

 

Due to the structure of the Individual Type A Gas Device Approval Scheme (scheme) it is recognised that the assessment process is limited in establishing an acceptable level of safety for gas devices (appliances) that fall outside particular parameters.

 

Appliances that may provide a possible or perceived elevated level of risk are not deemed eligible to be assessed under the scheme.

 

The elevated level of risk may be in relation to the design, construction, installation or use of a particular appliance, or due to the complexity of controls or process they are beyond the scope of the test criteria.

 

The below  appliances are currently excluded from the scheme, and clarifies defining design requirements for other particular appliances to be considered eligible.

 

Excluded appliances:

 

1.            Any appliance using a fuel gas that is not of the fuel gas quality and characteristics prescribed for consumers within chapter 7 of the Petroleum and Gas (Production and Safety) Act 2004

a.            Due to the elevated risks associated with biogas, hydrogen and other substances prescribed as fuel gas appliances using any gas other than standardised LP Gas or Natural Gas are excluded from the scheme are to be considered and approved under a gas device (type B) approval scheme.

 

2.            Appliances that are fuelled or include a fuel gas canister. Including but not limited to butane canister cookers (lunch box cookers), camping heaters, and canister lamps/lights.

a.            Safety-related functions of this type of appliance can only be assured through rigorous laboratory testing. There is an elevated level of risk due to the proximity of canister to a heat source, the reliability of shut-off and ejection systems. These appliances may be eligible under the nationally recognised type test scheme.

 

3.            “Yum-Char Trolleys” – mobile food cabinet, utilised for heating/warming food through a heating medium of water or oil, and include an LP Gas cylinder within the cabinet.

a.            There is no current Australian Standard to which this style of the appliance can be tested. Safety device requirements are not defined. There is an elevated level of risk due to the proximity of the appliance to the public in crowded spaces. The proximity of the LP gas cylinder to the heat source. The mobile nature of the appliance and spillage of heated liquids.

 

4.            Gas air conditioners with the capacity to consume no more than 500MJ in an hour

a.            There is no current Australian Standard to which this style of appliance can be tested. Safety device requirements are not defined. For more information contact gassafe@dnrme.qld.gov.au

 

5.            Portable gas generators with the capacity to consume no more than 500MJ in an hour

a.            There is no current Australian Standard to which this style of appliance can be tested. Safety device requirements are not defined. For more information contact gassafe@dnrme.qld.gov.au

 

Defined Design Requirements for Eligibiity

 

Particular gas devices may be defined as a gas device (type A) or a gas device (type B) dependent on the energy rating and/or other complexities, such as controls and other process requirements.

 

1. Coffee Roaster design eligible under the scheme (type A)

 

•             Appliance burner operating pressure not exceeding;

o             LP Gas 2.75 kPa; or

o             NAT- 1.00 kPa

•             Maximum gas consumption not exceeding 150mj/hr

•             Atmospheric burners only as defined in AS5263.0

•             Burner management system to be certified to Australian requirements

•             Flame supervision system to be

o             Thermocouple; or

o             Flame rectification/ionisation.

•             Natural draft or power flue as defined in AS5263.0

•             All gas components to comply with Australian requirements

 

Note 1: Where the coffee roasting process and/or flue system includes an ‘after burner’ as part of the process the appliance is not eligible to be assessed under the scheme.

 

Note 2: Where the above criteria is not met the appliance must not be approved under the scheme and is to be considered a gas device (type B).

 

Note 3: Where there is any doubt or lack of clarity the approval application must be considered in consultation with the Chief Inspector or delegate.
