Have any of y'all plumbed a Blackstone (or comparable) griddle into a nat gas line?

I currently have a pedestal mounted gas grill that has seen better days, like back when the former home owners lived here... I think we would use a griddle with a lid/cover way more than the gas grill. I have an offset smoker I used for grilling and smoking, so the gas grill doesn't get used that often.

You'll either have to replace the burners with natgas burners or modify the existing ones with larger orifices so it will burn natgas at a high enough temp to get the same performance.

Natural gas and propane are slightly different, natgas is a bigger molecule and needs a ever so slightly larger orifice to burn correctly versus propane.

Blackstone has a natural gas conversion kit on their website. https://blackstoneproducts.com/products/natural-gas-conversion-kit

Story of my life, bruh

Get the Blackstone natural gas conversion kit. It has everything you need, and you should be able to run the hose straight to your nat.gas line.

Awesome. Thanks for the advice y'all. I figured there was a conversion kit for the orifice sizing.

Any griddle recommendations?

Yes. Used the kit linked above.
36" 4 burner with a lid

Sounds like your question was answered. But I wanted to correct a misunderstanding up above in case anyone else referred to this thread later on.

Natgas (primarily methane) is a significantly smaller molecule than propane in terms of size. 1 carbon atom vs. 3 carbon atoms. Methane is 18 g/mol while propane is 44g/mol.

However, propane burns significantly hotter than methane. Propane's heating value is around 2557 btu/scf while methane's heating value is around 1012 btu/scf. So to get the same heating value, you need to burn about twice as much methane as propane which is why you need a larger orifice for natgas.

Probably more information than anyone needs or wants.

Go with the Blackstone. The H burners really do make a difference. Get the biggest one you can afford, you won't regret it. I have the 22" portable one, and I LOVE it for the camper. I'll be getting a bigger one when I catch them on sale for my next house.
