Type B appliances are commonly found in industrial sites. These appliances are defined in AS/NZS 5601.1 as an appliance with gas consumption exceeding 10 MJ/hour, for which a certification scheme doesn’t exist.
To operate a Type B appliance legally in all states and territories of Australia, the appliance must be certified. However, these
requirements may differ from state to state.
The Type B technical submission (or Appendix A) incorporates all items downstream of and including the appliance manual shut-off valve.
