Fixed installation means that you can connect a standard stainless flexible hose (found in your local hardware store) to our stove. In this way you avoid using a flexible rubber hose supplied from our other stoves. The resulting connection to our fixed installation stove is just like your other gas connection (gas water heater as an example). You can install it in your BBQ island. Typically you want to install a shut off valve (from your local hardware store) on the gas supply line upstream of the stove.
