Works as advertised, simple swap

I needed to switch my Ruby 4 burner from LP to natural gas for our new patio. This kit had everything I needed and the instructions were clear enough. Took about an hour to convert and test, no leaks.

Priya S.★★★★☆November 27, 2013
Good quality, minor hassle

The parts in this conversion kit feel solid, definitely Sunstone quality. Swapping out the orifices wasn't too bad, but getting to some of them was a bit fiddly. Once it was done, the grill fired right up on NG.

Carol O.★★★★☆March 20, 2026
Does the job, but pricey

Got my 36" Ruby running on natural gas, which is what I wanted. Parts are good, but the price felt a little steep for basically a few brass fittings and a hose. Easy enough for a DIYer to install.

Luis J.★★★★★May 22, 2019
Easy switch to natural gas

Really happy with this kit. We moved to a house with a natural gas line and it made switching my Ruby off propane easy. Grill works great and I don't have to worry about refilling tanks anymore.

Eli D.★★★★☆December 20, 2021
Easy to install, works great

I'm not the handiest guy, but I converted my 36" Ruby to natural gas with this kit without any problems. Flame looks good on all the burners and the grill heats evenly. Solid kit.

Questions & answers

5 questions answered

Q
After installing this kit, is there special maintenance for the new gas parts?Asked by Sunstone Support Team
A
Not much beyond normal grill cleaning. Check the gas connections now and then for leaks with soapy water and keep the orifices clear. Keeping the grill clean and covered when you're not using it helps everything last longer.

Q
My 36" Ruby is a few years old. How can I tell if this kit fits?Asked by Sunstone Support Team
A
It's made for the 36" Ruby 4B grill. Check your grill's model number, usually on a sticker under the hood or on the back. If it's a 36" Ruby 4B, this kit is the right one. If not, you may need a different kit.

Q
Can I install this conversion kit on my 36" Ruby 4B myself, or should I hire a pro?Asked by Sunstone Support Team
A
It's a simple conversion from natural gas to propane, or the other way depending on how your grill started out, but we generally recommend a pro. Working on gas lines takes experience to stay safe and get a good seal. If you're comfortable with gas connections and have the right tools, detailed instructions are included.

Q
What are the parts in this kit made of? Will they last on an outdoor grill?Asked by Sunstone Support Team
A
They're made to handle the outdoors and high heat, with brass orifices and sturdy metal fittings that resist corrosion and wear. With proper care they should last as long as your grill.
