Easy conversion

Moved recently and had to switch my Ruby from natural gas to propane. This kit was really easy to install, even for a DIY guy like me. Grill fires up perfectly now, no issues.

Kim L.★★★★☆January 8, 2019
Solid kit

Parts felt like good quality and the instructions were mostly clear. Had a question about one connection, but a quick call to support sorted it out. My 36 inch Ruby is running great on propane now.

Tanya P.★★★☆☆August 28, 2010
Works, a bit fiddly

It converted my grill from natural gas to propane, which is what I needed. Some of the small parts were finicky to get in place though, and the wrench that came with it wasn't a great fit. Works, just took more effort than I expected.

Vince R.★★★★☆August 3, 2022
Fit my 36 inch Ruby

Exactly what I needed for my 36 inch Ruby. Everything fit and the switch from natural gas to propane went smooth. Nice that they make a kit for this specific grill.

Becky O.★★★☆☆June 26, 2017
Works, but pricey

Works like it says and converted my grill to propane. Install was manageable, but the price for what's basically a few brass fittings and orifices was a bit steep. Does the job though.

Questions & answers

5 questions answered

Q
After converting to LP, what maintenance do the new parts need?Asked by Sunstone Support Team
A
Very little. Check the gas lines and connections regularly for wear or leaks, especially before and after the grill sits for a long time. Keep the orifices clean and clear so the flame burns right, same as any gas grill.

Q
What are the parts in this kit made of? Will they hold up outdoors?Asked by Sunstone Support Team
A
They're made from corrosion resistant materials, mostly brass and stainless steel for the important gas parts. They're durable and handle the outdoors, so your converted grill will last. A proper install and an occasional check keep them in good shape.

Q
I'm not very handy. How hard is it to install this conversion kit myself?Asked by Sunstone Support Team
A
The conversion is fairly simple, but it means working with gas lines and orifices. We recommend a qualified technician or a very experienced DIYer do it so it's safe and runs right. The kit has detailed instructions, but a pro install is the safest choice.

Q
Will this kit work on my older Ruby 36" or just the newest ones?Asked by Sunstone Support Team
A
It's made for the 36" Ruby 4B grill. If yours is an older model or a different Ruby series, it may not fit. Check your grill's model number against the kit specs to make sure it fits and runs safely.
