Works as advertised, simple swap

I needed to switch my Ruby4B from LP to natural gas for my new patio setup. This kit had everything I needed, and the instructions were clear enough. Took about an hour to get it all converted and tested, no leaks.

Steven M.★★★★☆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.

Ryan B.★★★★☆March 20, 2026
Does the job, but pricey

This kit got my 36" Ruby4B running on natural gas, which is what I wanted. The components are good, but I felt the price was a little steep for what's essentially a few brass fittings and a hose. Installation was straightforward enough for a DIYer.

Thomas N.★★★★★May 22, 2019
Perfect conversion for my Ruby4B!

Absolutely thrilled with this conversion kit! I moved to a new house with a natural gas line, and this made switching my Ruby4B from propane a breeze. The grill performs flawlessly now, and I love not having to worry about refilling tanks.

Linda M.★★★★☆December 20, 2021
Easy to install, great performance

I'm not the handiest person, but I managed to convert my 36" Ruby4B to natural gas with this kit without any issues. The flame looks good across all burners, and the grill heats evenly. Solid product from Sunstone.

Questions & answers

5 questions answered

Q
After I install this conversion kit, is there any special maintenance or cleaning I need to do for the new gas components? I want to keep my 36" Ruby4B Grill running smoothly.Asked by Sunstone Support Team
A
Once installed, the converted components of your 36" Ruby4B Grill generally require minimal special maintenance beyond your regular grill cleaning. It's a good practice to periodically check the gas connections for any leaks using a soapy water solution and to ensure orifices remain clear. Keeping the grill clean and covered when not in use will also prolong the life of all components.

Will this R-CKRuby4B kit work with my older Ruby grill? I have a 36-inch Ruby model, but it's a few years old. How can I be sure it's compatible?Asked by Sunstone Support Team

This R-CKRuby4B Gas Conversion Kit is specifically designed for the 36" Ruby4B Grill. To confirm compatibility with your older model, you'll need to check your grill's exact model number, which is usually found on a sticker under the hood or on the back.
