KoKoMo Classic Series · Model KO-BAK5BG
Six Heat Sources. 920 Square Inches. One Grill.
This is the grill you buy when the backyard is where everything happens. Five independent 12,000 BTU burners plus a dedicated infrared back burner give you 72,000 BTU and enough surface to run four different cooking temperatures at once — searing on the left, holding on the right, roasting on the rack, and a rotisserie turning behind all of it.
At 39¾ inches wide it's the anchor appliance of a real outdoor kitchen, not an add-on. Built entirely from 304 stainless steel, with the same ceramic briquette searing system and redundant SureLight ignition hardware KoKoMo puts across its Classic line.

Capacity & Fit
Who Needs This Much Grill
The host
If you're regularly cooking for ten or more, a 26" grill turns dinner into three shifts. 920 square inches puts everything on at once and gets everyone eating at the same time.
The rotisserie cook
The infrared back burner exists for one purpose: even, high-intensity radiant heat behind a turning spit. This is the model in the Classic line that supports it.
The full outdoor kitchen
An 8-foot-plus island with a fridge, side burner, and storage needs a grill that visually holds the center. A 26" head in a 10-foot island looks like an afterthought.

Heat Mapping
Five Zones You Can Actually Set Independently
Most people never use more than two heat settings because most grills can't hold more than two. With five separately valved burners across 39¾ inches, you can build a genuine temperature gradient from one end to the other — and cook a whole meal on it without moving anything twice.

High / sear
Medium / direct
Low / hold
One example layout. Every burner runs on its own valve, so the zones are yours to arrange.
Why the gradient matters
A thick ribeye wants 700°F for ninety seconds a side and then 300°F to finish. On a two-zone grill you're moving meat back and forth and guessing. Here you set burners 1 and 2 wide open, burners 4 and 5 low, and walk the steak left to right as it cooks. Chicken thighs render on the indirect end while corn chars on the direct end. Nothing waits.
Ceramic briquettes hold the zones honest
The commercial-grade ceramic briquette bed sits between the burners and the grates. It spreads each burner's heat laterally so a zone reads consistently across its full width instead of running hot directly over the flame. It also catches drippings before they reach open fire, which is what causes flare-ups — and unlike lava rock, it doesn't break down and need replacing.
Infrared Back Burner
The Burner That Changes What You Can Cook
An infrared back burner is a different heat source from the ones under the grates. Instead of heating air, it radiates directly onto the surface of the food from behind — the same principle as a restaurant salamander. KoKoMo rates this one at roughly 1,000°F within about 30 seconds.
What it's for
- Rotisserie chicken, pork loin, and leg of lamb with even browning on all sides
- Finishing a reverse-seared roast with a hard crust and no overcooked band
- Charring peppers, or crisping skin without drying out what's underneath
- High-heat wok and stir-fry work in a pan set on the rear grates
Lighting it correctly
The back burner lights differently than the main burners and it catches people out. Turn the knob slowly and stop just before the ignition snaps, then hold for seven to ten seconds. That lets gas travel across to the far side where the igniter sits. Then complete the turn. It's in the manual, but almost nobody reads that page first.
The rotisserie kit is sold separately. The back burner is included with the grill; the motor, spit rod, and forks are an add-on. We stock the KoKoMo rotisserie kit sized for five-burner models — add it at the same time and it ships together.
Construction
304 Stainless, Front to Back
KoKoMo builds this unit entirely from 304 stainless steel — the grade specified across commercial kitchens and marine applications for corrosion resistance and sanitation. It matters more outdoors than most buyers expect: a built-in grill lives through rain, sprinkler overspray, pool chemistry, and salt air, and lower stainless grades show it within a couple of seasons.
-
Dual-wall hood construction — two stainless layers with an air gap, keeping the exterior cooler and holding heat inside the cooking chamber
-
Seamless polished edge along the hood perimeter, with no welded seam line to trap grease
-
Non-coated commercial-grade cooking grids, heavier and tighter-spaced than typical for this class — thermal mass is what produces sear marks rather than just cooking meat through
-
Full-width stainless drip tray spanning the firebox, pulling straight out for cleaning
-
Hood-mounted temperature gauge for reading chamber temperature with the lid closed
-
1" mounting flange on all four sides, concealing a rough cutout edge for a clean drop-in
Ignition & Control
Six Igniters, Not One
SureLight primary ignition
Every burner carries its own dedicated SureLight igniter. On a five-burner grill this is the difference between an appliance you enjoy and one you resent. Single-igniter systems mean one failed component takes the whole grill down to match-lighting. Here each knob operates an independent system — a failure on one burner leaves the other four untouched.
Flash-tube secondary ignition
Behind the primary igniters, a flash tube carries flame between burners as a backup lighting path. Combined with the individual igniters, that's genuine redundancy on the component that historically fails first on any outdoor grill.
Manual lighting is documented too. The manual covers match-lighting through the lighting tube and the five-minute gas-clearing wait between attempts. Worth reading once before your first cook rather than in the dark with guests waiting.

Island Requirements
The island must be built from non-combustible material — framing a grill cutout in wood is the most common and most dangerous mistake in DIY outdoor kitchen builds. Maintain a minimum 14" clearance from the sides and 16" from the back to any adjacent combustible construction, and plan island depth around that before setting block. Installation must conform to local code, or to National Fuel Gas Code ANSI Z223.1 where none exists. Check with your city and fire department; outdoor kitchen construction often requires a permit.

A note on gas type. KoKoMo ships these units configured for liquid propane, with a natural gas conversion kit included in every shipment. If you ordered the natural gas variant, the orifice conversion still needs performing — and per the manufacturer, by a licensed gas professional. Factor it into your installation quote rather than discovering it on hookup day.

Three Add-Ons That Actually Get Used
Rotisserie kit for 5-burner grills
Motor, spit rod, forks, and mounting brackets sized for this model. Pairs with the infrared back burner that's already built into your grill — without the kit, that burner sits idle.
Canvas cover, 5-burner size
The manual specifically calls for keeping the grill protected from weather. A correctly sized cover is the cheapest thing you can do to keep 304 stainless looking new through winter.
Stainless smoker box insert
Drops between the grates to add real wood smoke to a gas cook. Chips smolder against burner heat rather than burning off, which is what actually puts smoke flavor into the food.
Ordering accessories with the grill keeps everything on one shipment. Call 833-777-2962 and we'll confirm fitment for your exact configuration before anything ships.
Warranty & Support

Coverage is valid at the original delivery site with proof of purchase. Full terms are in the manual.
Register your unit
The serial number sits on the left side of the firebox. Record it with your model number and purchase date before installation — once a 138-pound grill is seated in a masonry island, that label becomes very hard to reach.
Authorized dealer support
Buying through an authorized dealer keeps your warranty valid and gives you a real person to call. If a claim needs filing, reach us at 833-777-2962 or info@smokeforges.com and we handle it with KoKoMo directly.
Common Questions
Questions Before You Buy
Is the rotisserie kit included?
No. The infrared back burner is built into the grill and included, but the rotisserie kit — motor, spit rod, forks, and brackets — is a separate purchase. We stock the KoKoMo kit sized for five-burner models and can add it to the same shipment. If rotisserie cooking is the reason you're buying this grill, order both together.
Does 920 square inches include the warming rack?
Yes, and we'd rather say so plainly since most listings don't. The 920 figure is total cooking area with the warming rack counted in. The primary grid is where you'll do the real work. It's still a substantial grilling surface for a 40" unit — comfortably a couple dozen burgers — but plan around the primary grid when you're calculating capacity, not the headline number.
What's the difference between this and the KoKoMo Professional Series 40"?
The Classic line uses stainless pipe burners at 12,000 BTU each. The Professional line steps up to cast stainless burners at 15,000 BTU each, adds heat zone separators and an interior lighting package, and reaches 87,000 BTU total. Both are 304 stainless and share the ignition and briquette systems. If you cook after dark, run multiple temperatures at once, or want the heaviest burner hardware in the line, look at the Professional. For most residential cooking, the Classic delivers what you'll actually use at a meaningfully different price.
Can I use this on a cart instead of building it in?
Yes. The same grill head that drops into an island mounts to a KoKoMo cart sized for 40" heads, which adds side shelving and enclosed storage for a propane tank on caster wheels. If you're not ready for a masonry island — or you're renting — that route lets you buy the grill now and build around it later. Call us to confirm current cart availability.
My grill is natural gas. Is it ready to connect out of the box?
Not quite. KoKoMo ships these configured for liquid propane with the natural gas conversion kit in the crate. The orifice change-out has to happen before connecting to a natural gas line, and the manufacturer specifies a licensed gas professional for that work. The natural gas regulator is supplied and should be set to 4.0" water column. Liquid propane installs need an 11" water column regulator, which is not supplied.
How much clearance does the island need?
Minimum 14" from the sides and 16" from the back to any adjacent combustible construction, and the island itself must be built from non-combustible material. Get those numbers to whoever is designing the island before block goes down — retrofitting clearance into a finished island is not a small job.
What does delivery look like on a grill this size?
It ships free on all orders. At 138 pounds crated, this moves by freight rather than parcel, on a pallet. You'll be contacted to schedule a delivery window. Plan on having a second person available — both for offloading and for setting the grill into the cutout, which the manual specifically calls for two people to do.
Can I return it if it doesn't fit my island?
Eligible unused returns are subject to our published return policy, including freight and restocking conditions; and we'd much rather help you avoid the situation. Measure your opening against the cutout dimensions above, and if there's any ambiguity at all, call
833-777-2962 before ordering. Ten minutes on the phone beats a freight return on a 138-pound crate every time.
