G2F1 requires that a heating system be installed to prevent fire spreading to adjoining building elements.

A key expression in G2F1 is “controlled combustion”. This expression means that only heating units which burn solid materials or oil must comply with these provisions. The expression applies to open fireplaces, oil heaters, solid-fuel burning stoves, coal heaters, pot-belly stoves, and other such cooking and heating devices.

The expression does not include electric heaters. Nor is it intended to include gas heaters covered by other State and Territory legislation.
