NEW INTERLOCK REQUIREMENTS FOR ENCLOSED ALFRESSCO BARBECUES

The standard for commercial and residential gas installations in Australia AS5601.1.2013 was amended in May of this year with many new requirements.

One significant change which will affect some gas barbecue installations is a new clause 6.10.1.15. This clause requires that an appliance approved for commercial use, installed in residential premises, be fitted with an interlock to the gas supply so that the installed extraction system must be in operation before gas will flow to the appliance.

In Western Australia many Alfresco areas are being enclosed or semi enclosed meaning that appliances approved for outdoor use can no longer be fitted in the area. Energy Safety will accept appliances approved for commercial use being installed providing certain conditions are met. Energy Safety have issued this information sheet

In general terms the main conditions are,

1. The appliance is approved for commercial use by an Independent Type A gas appliance Inspector or an approved Certifying Body.
2. A flame failure system is fitted
3. The appliance is installed under a compliant extraction system/range hood
4. The extraction system/range hood is interlocked to the gas supply
