Can I connect my Ooni to my RV?

Yes, your Ooni oven can be connected to your RV gas supply as long as the gas pressure is correct:

If your gas supply is 27-28mBar: Your gas pressure is regulated to a low pressure. This means that you can connect directly to your RV using a standard gas hose that can be purchased from most hardware stores.

If your gas supply is more than 28mBar: You'll need to use the supplied 28mBar regulator or a similar 28mBar regulator to ensure that your gas pressure is correct.
