How should gas piping be evaluated when buying a rotating clay-pot cooker?

Gas piping checks start with the maker's rated consumption and inlet pressure for one burner. From there size the main and branch lines for the maximum number of burners lit at once, not just the catalogue figures. When several rotary claypot cookers share a supply, watch whether end pressure drops below the allowed minimum the moment every burner ignites; flames should stay steady without lifting or flashback. Fire all burners together at full load, log gauge readings and flame behaviour, and keep gas source details, regulator settings and results, since one cooker running fine proves nothing about the whole line.
