60,000 BTUs of Direct-Grilling Power, Plus a 15,000 BTU Rotisserie Burner Built In
The Sunstone Ruby Series RUBY4BIR pairs four-burner output with a ready-to-use infrared rotisserie system — no separate kit to order later.
The Sunstone Ruby Series RUBY4BIR is a 36-inch built-in gas grill built entirely from 304 stainless steel, combining 837 square inches of direct-grilling space across four main burners with a dedicated 15,000 BTU infrared rear burner and included rotisserie kit. It's built for cooks who want both high-heat searing and slow, rotisserie-style roasting from the same built-in unit, with independent Flame-Thrower ignition, heat-changing LED control panel lighting, and interior halogen lights for after-dark grilling.

60,000 BTU
Four Burners for Direct Grilling
Four 11-gauge fabricated I-burners deliver up to 60,000 BTUs combined, giving you the heat reserve to run multiple zones at full output without losing temperature.
15,000 BTU
Built-In Rotisserie Burner
A dedicated 15,000 BTU infrared rear burner powers slow, even rotisserie roasting — no separate burner kit to track down and install later.
Included
Rotisserie Kit Ships With the Grill
The rotisserie kit is included, so you can spit-roast a chicken or rack of lamb the same week you install it, instead of waiting on a separate accessory order.
837 sq in
Room for a Full Spread
653 square inches of primary grates plus 184 square inches of secondary warming space means mains and sides cook together without crowding the grates.
304 SS
Built for the Long Haul
Every panel, burner, and grate is built from 304 stainless steel, so the grill holds its finish through humid summers and salty coastal air instead of pitting after a season.
LED + Halogen
Built for Night Grilling
Heat-changing LED lighting on the control panel and halogen interior lights mean you can read doneness and dial in temperature long after the sun goes down.

Deep Dive — Two Cooking Styles, One Gas Line
▸
One Grill, Two Cooking Styles
Run the four main burners for direct, high-heat grilling, or switch to the rear infrared burner and rotisserie kit for slow, even roasting on a rotating spit. Both draw from the same gas line, so you're not managing a separate fuel source for each cooking style.
Sized to Drop Into a 33 1/2" x 22" x 10" Cutout
The RUBY4BIR shares its footprint with the RUBY4B, dropping into a 33 1/2-inch by 22-inch by 10-inch cutout, with an overall size of 36 inches wide by 27 inches deep by 22 inches tall. Measure your island opening against these numbers before you order so the grill seats flush on install day.
Choose Your Fuel Type
The RUBY4BIR is available in liquid propane (RUBY4BIR-LP) or natural gas (RUBY4BIR-NG) configurations — select your fuel type above to match your existing gas line.
Who It's For — The Deck & Den Take
▸
The Deck & Den Take — If you already know you want a rotisserie down the line, this is the simpler buy: it skips the separate accessory order and arrives ready to roast. Use the rear infrared burner for whole birds and larger roasts, and lean on the four main burners for everyday direct grilling — you're not choosing one cooking style over the other.
-
Cooks who want both direct grilling and rotisserie roasting from one built-in unit, without ordering a separate kit later.
-
Built-in island owners hosting larger groups who need real four-burner capacity.
-
Anyone who roasts whole birds or larger cuts regularly, where a dedicated infrared rotisserie burner beats rigging one onto a standard grill.
-
Hosts who entertain after dark and want LED and halogen lighting built in, not bolted on.
-
Buyers comparing the RUBY4B and RUBY4BIR who've decided the rotisserie system is worth having from day one rather than adding it later.

Frequently Asked Questions
▸
What's the difference between the LP and NG versions?▸
RUBY4BIR-LP runs on liquid propane and RUBY4BIR-NG runs on natural gas. Both share the same burners, dimensions, and features — select the fuel type that matches your existing gas line.
How many BTUs does the RUBY4BIR put out?▸
The four main I-burners produce a combined 60,000 BTUs for direct grilling. A separate 15,000 BTU rear infrared burner powers the rotisserie system independently.
Is the rotisserie kit actually included?▸
Yes — unlike the standard RUBY4B, where the rotisserie kit is an optional add-on, the RUBY4BIR ships with the rotisserie kit (motor, spit rod, and forks) included.
What does the infrared burner do?▸
It's a rear-mounted 15,000 BTU burner built primarily to power the rotisserie system for slow, even roasting, while also adding finishing heat for caramelization.
How is this different from the RUBY4B?▸
Both share the same four-burner, 60,000 BTU chassis and 837 sq. in. of cooking space. The RUBY4BIR adds a dedicated rear infrared burner and includes the rotisserie kit standard, where it's an optional purchase on the RUBY4B.
What cutout size do I need for installation?▸
The grill requires a 33 1/2 in. wide by 22 in. deep by 10 in. tall cutout. Confirm your island's opening against these dimensions before ordering.
What's included in the box?▸
The grill ships with the rotisserie kit, a smoker box, back hood wind guards, Spill-Away and Heat-Riser warming grids, a hose and regulator pre-configured for your selected fuel type, and the owner's manual.
What's covered under warranty?▸
Sunstone covers the stainless steel burners, cooking grids, and housings for the lifetime of the original purchaser, and other components such as ignitors, knobs, valves, and tubing for one year. Full terms are in the product manual above.
How is each burner lit?▸
Each burner has its own independent Flame-Thrower ignition, so lighting one zone doesn't depend on the others working.
Can I convert this grill between propane and natural gas later?▸
Yes — Sunstone's Ruby Series gas conversion guide covers converting between LP and NG, including the additional steps needed for grills with an infrared rear burner like this one.
What if it doesn't fit my island?▸
If the unit doesn't fit your cutout or isn't right for your setup, it's covered by Deck & Den's 45-day return policy — just contact us before sending it back.
