Hose and regulator

Check the hose; replace it every 5 years

The manual: "It is recommended to replace the gas hose every 5 years. Some countries may have different requirements", and you must follow those.

1. Before each use, check the hose along its length for cuts, cracks and wear.
2. Check the regulator and both hose ends for damage.
3. Replace the hose every 5 years, or sooner if your country's rules say so.
4. Buy for your country. In the UK: a 37 mbar propane regulator to EN 16129, and hose to EN 16436-1 Class 2, 8 mm bore, no longer than 1.5 m (help centre).
5. Leak test every joint you have undone.

Gozney gives no replacement interval for the regulator.
