Another Nice firepit in decking project.
This customer recorded all his hard work with this series of images.
The one slight concern is lack of ventilation. Those double sized airbricks have 36 1cms holes ie. 36 square cms. Our burner requires 100 square cms. Not only that, the ventilation hole was then mostly covered by a decking beam. However he’s never reported a problem so it must be ok.
If building a bottle store, make sure there’s plenty of ventilation holes at ground level. If the bottle leaked, LPG gas is heavier than air, so would fall to the ground. So you must allow the gas to escape, or it will fill up the storage unit with gas. Not good.
