Step down gas pipe

We have had an lpg tank fitted with the connection point on the wall, and we need to fit a new lpg heater to it. Do we need a regulator or can we just step down the pipe size with connectors?

    If there's no regulator on the tank, you need one... usually your gas supplier won't even supply gas to a fixed tank without checking the installation themselves -- and they'll usually do it as well for you.

    Thank you. There is of course a regulator on the tank. We are waiting for a Warma grant to install a boiler and radiators, but in the meantime need some heat! We have done our own installs in various vehicles and caravans, just never from a big tank, always from bottles.

    Normally with LP with a fixed tank there is a regulator on the tank and another regulator on the outside of the building where the LP pipe enters the house.

    Bottom line is an LP appliance needs about 12" of wc gas pressure on the outlet side of the regulator on the outside of the house and the appliances need to be set up for LP

    Thank you @EBEBRATT-Ed, that's great. It's a static caravan so all appliances are lp, and yes there is also a regulator on the end of the pipe to the outside wall. Cheers 😊
