I am thinking of getting a duel fuel cooker (freestanding) in place of my present natural gas cooker.
When I pulled the cooker out to look for electrical and gas connections (it has double pole control unit 32A with switch to the side and above the hub of the cooker) but the flexible gas connector does not have a gas isolating valve to the cooker, should it have one ? ( The gas input to the whole house can be switched off in the garage).
