mikeyj,,,good morning,,,found this should help your question,,,do not have a grille now but similar to a cafe grille we had in the past,,,,go to Alliancerv.com,,,under the Delta brand name is an Owners manual,,,on page 177 they explain how to unpack your grill & have a video of how to connect your gas propane. No legs mentioned,,,it appears to be a locked slideout ”drawer/ support w locking bar near your gas valve That keep the grille from moving,,,,mebbe there is also another you tube video explaining the process if you google it Not very good at getting links posted to make this easier,,,, hope this helps. 👍🌞🍀!
