I have purchased a free standing full gas stove and oven, and am in the process of doing the installation. My intention is to install a 9 kg bottle in a kitchen cupboard, connect the gas and then get someone to give me a gas compliance certificate. I have a copy of the South African regulations, but I have one question:

Is the gas regulator the same as the gas heater regulator? When trying to purchase the regulator, all products have the same specifications 2.8 KPA which is the same as the heater and bottle I have which is also a spare heater bottle. The stove is also set up for LP gas at 2.8 KPA. Is there something I am missing?
