All Delta Heat grills and side-burners are required to use a regulator.
This regulator is convertible to LP Liquid Propane for bulk/all-house propane setups, see images. However, this regulator should not be used as a direct replacement to the S15344 Regulator for LP and still should be purchased for 5gallon/20lb tanks setups. Any questions about this please contact our service department: firstname.lastname@example.org or 562-263-3600.
The input into this regulator is 1/2″.
Each, sold separately.
