BrandSunstone

The Sunstone SUNJK insulated jacket is the heat barrier Sunstone pairs with its current Ruby built-in grills. Sunstone offers it in three widths, each matched to specific grills: the 33" SUNJK33 for the Ruby 30" RUBY3B, the 40" SUNJK40 for the Ruby 36" RUBY4B and RUBY4BIR, and the 45" SUNJK45 for the Ruby 42" RUBY5BIR and Emerald 42" EMCHDZ42. The grill drops into the jacket's sleeve and rests on its top edge, and the jacket sits in a larger island opening than the grill would need on its own, so plan the cutout around the jacket before the island is framed.

Key Features

  • Matched by Sunstone to Ruby grills — Sunstone lists each size against named grills: SUNJK33 with RUBY3B, SUNJK40 with RUBY4B and RUBY4BIR, SUNJK45 with RUBY5BIR and EMCHDZ42.
  • Heat barrier for nearby combustibles — Sunstone's Ruby manual names a grill jacket as one of the heat barriers to use when combustible material is within 24" of the grill.
  • Grill rests on the jacket rim — the grill sits on the jacket's top edge, not on its base, leaving space below the drip pan for air flow. Sunstone notes the jacket raises the grill 1" above the counter.
  • Removable side access panels — left and right panels come off for gas and electrical access.
  • Removable vent panel — the sleeve is 10" high with the vent panel in place, or up to 12" high with it removed.
  • Peg legs and upgrades — fasten-in peg legs let the jacket and grill stand on any surface; Sunstone also offers a post mount upgrade (SUNJKPOST) and jacket wings (SUNJKWING).

Fits These Grills

These SUNJK jackets replace Sunstone's earlier SUN3BJK, SUN4BJK and SUN5BJK drawer-style jackets, which were sized for Sunstone's older 28", 34" and 42" grills and are no longer sold. Sunstone lists only the SUNJK jackets for its Ruby grills.

Installation Note

The jacket changes the hole you cut in the island. A Ruby 36" RUBY4B on its own needs a 33-1/2" x 22" x 10" cutout; with the SUNJK40 the island opening becomes 38-3/4" x 24-1/4" x 13", and the grill drops into the jacket's 34" x 22" sleeve. Frame to the jacket cutout in the table above, not to the grill's cutout.

Sunstone's Ruby Series manual asks for 24" of clearance from combustible materials in any direction of the grill. If any combustible material is within that 24", the manual calls for a heat barrier such as a grill jacket, or non-combustible material such as brick, cement board or metal. The manual also states that the 24" clearance under the countertop to combustible construction can be modified by use of an insulated jacket. Follow your grill's installation manual and local code, and have a licensed professional connect the gas. Our built-in grill cutout dimensions page lists grill cutouts by brand, and do you need an insulating grill liner? explains when a jacket is worth it.

Frequently Asked Questions

Which SUNJK jacket fits my Sunstone grill?

Sunstone matches each size to named grills. The 33" SUNJK33 fits the Ruby 30" RUBY3B. The 40" SUNJK40 fits the Ruby 36" RUBY4B and the Ruby 36" RUBY4BIR. The 45" SUNJK45 fits the Ruby 42" RUBY5BIR and the Emerald 42" EMCHDZ42.

Choose by grill model rather than by the nominal size in the jacket name.

What island cutout does each jacket need?

Frame the island to the jacket, not the grill. The SUNJK33 needs 31-1/2" wide by 24-1/4" deep by 13" high, the SUNJK40 needs 38-3/4" wide and the SUNJK45 needs 43-1/2" wide, both at the same 24-1/4" depth and 13" height.

Overall jacket sizes are 33-1/4", 40-1/4" and 45-1/4" wide, each 25-3/4" deep and 14-1/4" high.

How big is the sleeve the grill drops into?

The sleeve is 26" wide on the SUNJK33, 34" on the SUNJK40 and 39" on the SUNJK45, each 22" deep and 10" high with the vent panel in place, or up to 12" high with the vent panel removed.

The grill rests on the jacket's top edge rather than on its base, which leaves space below the drip pan for air flow. Sunstone notes that the jacket raises the grill 1" above the counter.

How much bigger is the cutout than the grill alone?

On its own a Ruby 30" RUBY3B needs a 27-1/2" x 22" x 10" cutout; with the SUNJK33 the opening becomes 31-1/2" x 24-1/4" x 13". The Ruby 36" RUBY4B and RUBY4BIR go from 33-1/2" x 22" x 10" to 38-3/4" x 24-1/4" x 13" with the SUNJK40, and the Ruby 42" RUBY5BIR goes from 39-1/2" x 22" x 10" to 43-1/2" x 24-1/4" x 13" with the SUNJK45.

Our built-in grill cutout dimensions page lists grill-only cutouts by brand.

Do I need an insulated jacket for a Ruby grill?

Sunstone's Ruby Series manual asks for 24" of clearance from combustible materials in any direction of the grill. If any combustible material is within that 24", the manual calls for a heat barrier such as a grill jacket, or non-combustible material such as brick, cement board or metal.

The manual also says the 24" clearance under the countertop to combustible construction can be modified by use of an insulated jacket. Check your local code before you finalize the island, and read do you need an insulating grill liner? for more.
