New amendment to gasfitting standard AS/NZS 5601 Part 1

Smoke test
Recent changes to gasfitting standard AS/NZS 5601.1 require gasfitters to account for external weather conditions before testing for negative pressure and carbon monoxide spillage.

The new Amendment 3 to AS/NZS 5601.1: 2013 General Gas Installations, published on 24 April 2020, includes a new baseline conditions test, which must be performed as part of the spillage test requirements under Appendix R – Spillage Test for Flued Appliances.

Open-flued gas appliances can be affected by external temperature conditions or wind gusts, which can impact the smoke pattern seen during a smoke test.

By establishing a baseline smoke pattern for each appliance, gasfitters can determine whether the smoke pattern observed during a negative pressure test is a result of external weather conditions or the operation of exhaust fans and kitchen rangehoods.

All gasfitters working on gas appliances must familiarise themselves with the new, updated test procedure.
