Gas BBQ interlocking Systems

Indoor Barbeques -What you need to know!

I came across this article from Atco Gas which explains a lot about the rules and regs for indoor Barbeques, especially interlocking systems and how they work.

ADDITIONAL INFORMATION:

BBQ to be re-certified:

• Re-certification must be undertaken by an approved Type A Gas Appliance Inspector
• See list of Independent Inspectors on Energy Safety website

Some outdoor BBQs already have a flame failure system (additional safety feature) fitted which makes re-testing and certification to AS4563 simpler and cheaper.
Having a flame failure system retrofitted is costly and the appliance will still need to be tested and approved

Note: the inspector who re-certifies the appliance must be independent and cannot also undertake any of the other installation work (appliance, ventilation or interlock).
  

Extraction Fan:

• A commercial style range hood/extraction canopy must be fitted above the appliance to provide adequate ventilation as Standard AS/NZS 5601 dictates.
• The extraction fan filter must not be closer than 1,200mm to the cooking surface.
• The fan must move at least 2,000m3 of air per hour. ATCO recommends the use of a 2 motor fan to achieve this flow rate.
• Not only will the fan remove any harmful products of combustion, but it will also stop grease and smoke from damaging the alfresco walls and ceiling.
 

Interlock system to be installed:

• The re-certification process means that the appliance is now considered a ‘commercial’ appliance – for domestic use.
This requires the appliance to have an interlock installed, so that the extraction fan is operating before gas will flow to the appliance. Ref: AS/NZS 5601.1:2013 Clause 6.10.1.15
