What is Type B Gasfitting work?

Get to know the regulation

Under Part 4 of the Plumbing Regulations 2018, Type B Gasfitting work is:

  1. the construction, installation, servicing, maintenance, commissioning, replacement or repair of a single Type B appliance of an energy input greater than 10 MJ/h and less than 5000 MJ/h between the connection to the gas isolating valve adjacent to the appliance and any flue connection; and
  2. the commissioning, construction, installation, servicing and maintenance of a steam boiler or thermal fluid heater of input less than 20 000 MJ/h that forms part of an integrated industrial process between the gas isolating valve adjacent to the appliance and any flue connection, including the repair and replacement of gas components in that appliance.

Type B Gasfitting work does not include:

  1. the adjustment of input parameters on a programmable burner management system associated with a Type B appliance
  2. the commissioning of a Type B appliance in the absence of manufacturer-supplied commissioning data
  3. any work on a Type B appliance where the appliance is associated with volatile solvents or hazardous atmospheres
  4. any work on a component of a Type B appliance which is not involved in the supply of gas, use of gas or control of gas related hazards
  5. the positioning of a Type B appliance except where it involves a connection to the gas isolating valve; or
  6. electrical work within the meaning of the Electrical Safety Act 1998 that is not involved in the supply of gas, use of gas, or control of gas related hazards

Typical Type B Gasfitting 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 gasfitting 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.
