Typical Type B Gasfitting Advanced work

Gas appliances can vary in size, operating pressure and complexity, ranging from small domestic gas space heaters to large industrial steam boilers or industrial furnaces. Victoria's Gas Safety Act 1997 defines gas appliances as either Type A or Type B.

Gasfitting work with these two types differs in nature, complexity and risk. For this reason, gasfitters need to be qualified for and experienced with the type of appliance with which they are working.

Experienced Type B Gasfitting Advanced plumbers typically do the following work with Type B appliances:

  • analysing and interpreting design specifications for Type B gas appliances
  • installing and testing Type B gas appliances and components, including undertaking gas and electrical safety checks, and completing and recording isolation procedures
  • installing and commissioning Type B gas appliances and components that use LPG, natural gas, combination fuels or tempered liquefied petroleum gas
  • testing flue gases
  • servicing Type B gas appliances
  • repairing or replacing Type B gas appliances according to manufacturer specifications
  • repairing, replacing, altering or modifying Type B gas appliances and any associated safety systems
  • ensuring Type B gas appliances operate safely and efficiently, accounting for all other plant and equipment and any associated manufacturing processes
  • determining any design alteration work and/or modifications to Type B gas appliances comply with the relevant regulator’s requirements.
