We've just purchased a Blackstone gas griddle (nice piece of kit but fairly hefty at 13kg). It comes with a regulator to be attached between griddle and gas canister. As I will be using the MH external gas point to connect to, will I still need the regulator given there is one fitted in the gas locker? I'm fairly certain the answer is no but don't want to take any chances with gas....particularly as my partner will be the one using it; I have no illusions in my ability to cook!
