Type B Gas Appliance Design

What is Type B compliance?

Type B appliances are commonly found in industrial sites and are defined in AS/NZS 5601.1 as an appliance with gas consumption in excess of 10 MJ/hour for which a certification scheme doesn’t exist.

Examples of Type B gas appliances

Industrial boilers

Incinerators

Gas-fired turbines

Engine powered appliances used in power generation

Certification may differ from state to state

To operate a Type B appliance legally in all states and territories of Australia, the appliance must be certified, these requirements may differ from state to state, however.
