First fire and seasoning

Season it: 30 minutes on full

Outdoors only. The manual: never in a building, garage or any enclosed area, and never on or under a balcony or deck. Burning gas makes carbon monoxide, which you cannot see or smell.

The manuals have no seasoning step. This is from the Essentials Guide and the help centre: it burns off oils and coatings left from manufacture.

1. Put the stone in and do the leak test.
2. Light it and turn the knob to Max.
3. Run it empty for 30 minutes: the help centre says that is around 450 °C (850 °F).
4. Turn it off and let it cool completely.
5. Wipe the inside with dry paper towels, wearing gloves.
