Setting up an outdoor kitchen around a continuous gas line eliminates the friction of swapping twenty-pound propane cylinders midway through a cookout. For backyard cooks who host large gatherings or prepare weeknight family dinners, tapping into a home gas supply provides steady fuel pressure and uninterrupted cooking sessions. Choosing a monument natural gas grill requires deciding between dedicated natural gas cart platforms and convertible dual-fuel setups that require separate conversion components. Evaluating these options involves examining how burner outputs, lid viewing windows, ignition setups, and smart digital temperature probes align with your patio workflow.
The Monument product catalog organizes its cooking systems into distinct structural tiers based on fuel delivery and monitoring technology. Entry cart units provide pre-configured natural gas valves straight out of the box, whereas larger cabinet models use a dual-fuel architecture engineered to switch fuel sources using an external conversion kit. At the premium end of the spectrum, the Denali line integrates Bluetooth app tracking, digital display consoles, and specialized multi-zone burner arrays. Understanding how burner counts, physical dimensions, and fuel restrictions vary across these models will help you clarify your monument gas grill comparison and select the right platform for your culinary routine.

The Models in Detail
01
Monument Grills 4+1 Burner Natural Gas
Monument Grills 4+1 Burner Natural Gas
Best for: Homeowners with direct patio natural gas plumbed
Pros
- Dedicated natural gas hose included
- Fast 650°F Broil Zone sear layout
- Clearview window monitors food without heat loss
- Corrosion-resistant 304 stainless steel burners
Cons
- Does not support liquid propane
- No exterior side burner included
The Monument Grills 4+1 Burner Natural Gas grill (model M415BZNG) is built specifically for homes equipped with an exterior natural gas hookup. Because it arrives configured solely for natural gas and includes a dedicated natural gas hose, you avoid the hassle of swapping burner orifices or adjusting manifold pressures. The core cookbox houses four main burners crafted from 304 stainless steel, which deliver strong rust resistance and resist clogging over years of outdoor exposure. Across its five total heating elements, the grill generates 50,000 BTUs of total cooking power, providing fast, even heat distribution across the 450 square inches of primary grilling area.
High-heat performance centers on the integrated Broil Zone, which is engineered to hit temperatures up to 650°F in ten minutes. This rapid heat transfer relies on a specialized U-shaped flame layout paired with a flame tamer containing dense V-shaped perforations, designed to minimize flare-ups and eliminate uneven cool zones during high-heat searing. Above the cast iron cooking surface, a 180-square-inch warming rack brings the total capacity to 630 square inches. The cookbox is enclosed by a dual-layered lid featuring a built-in Clearview glass window, allowing cooks to inspect steaks or poultry without lifting the hood and venting trapped heat. If you are comparing installation plumbing with other outdoor cooking stations, exploring a blackstone natural gas conversion can provide helpful context on line fittings and supply pressures.
Day-to-day workflow benefits from illuminated control knobs, an integrated bottle opener, and stainless steel side shelves fitted with tool hanging hooks. Enamel-coated cast iron grates offer balanced thermal mass while remaining easy to scrape down, supported by an exterior non-stick coating and a streamlined grease funnel system that channels drippings into a removable tray. With a footprint measuring 22 inches deep by 55 inches wide and rolling on lockable swivel casters, this model suits grillers who want a ready-to-run natural gas setup without additional conversion parts. It yields to larger models when you need enclosed lower cabinet storage or auxiliary side burners for simmering sauces.
02
Monument Grills Larger Convertible 4-Burner Natural
Monument Grills Larger Convertible 4-Burner Natural
Best for: Cooks planning a future natural gas transition
Pros
- Dual-fuel convertible architecture with kit included
- Enclosed two-door storage cabinet design
- 60,000 BTU output across five burners
- Durable enameled cast iron grates
Cons
- Grill and conversion kit ship separately
- Lacks digital smart probe integration
The Monument Grills Larger Convertible 4-Burner Natural grill expands your cooking possibilities by adopting a convertible dual-fuel architecture. Unlike fixed cart units, this cabinet-style station is engineered to run on liquid propane or convert over to natural gas using the dedicated conversion kit model 97352. The listing pairs the grill with the kit across two packages, making it an adaptable choice for homeowners planning a future gas line extension while using standard propane tanks in the interim. Inside the firebox, four 304 stainless steel main burners work in tandem with an exterior side burner to generate a substantial 60,000 BTUs of heat output.
Cooking capacity is generous, offering 700 square inches of total grilling surface divided into 510 square inches of primary space and a 190-square-inch secondary warming rack. Heat is absorbed and distributed by heavy enameled cast iron grates, which provide strong thermal retention for crisp sear marks while resisting porcelain chipping. The Clearview viewing window embedded in the lid gives you visual control over internal cooking conditions, reducing unnecessary lid lifting that destabilizes internal oven temperatures. For cooks exploring varied outdoor gear formats, comparing this enclosed cabinet arrangement with an ultralight setup like a blackstone camping grill highlights the trade-offs between permanent patio workspace and portable cooking convenience.
Below the burner deck, an enclosed double-door cabinet provides weather-protected storage for tools, grill covers, and accessories. Precise flame valves allow you to establish discrete direct and indirect heating zones, making it easy to sear burgers on one side while gently roasting vegetables on the other. Measuring 19 inches deep, 54 inches wide, and 46 inches high, this model represents a practical middle ground for grillers seeking higher heat output and side-burner versatility. It gives way to the Denali line when smart digital monitoring and higher burner counts become essential for your weekend cooking routine.

Monument Grills Denali Series
Monument Grills Denali Series
Best for: High-capacity entertaining with smart digital monitoring
Pros
- Massive 84,000 BTU seven-burner cooking system
- Bluetooth smartphone app with meat probe
- Color-coded LED knob lights with Type-C power
- Dual-fuel natural gas conversion kit included
Cons
- Requires substantial deck space
- Bluetooth connectivity requires line-of-sight proximity
The Monument Grills Denali Series Denali 605 brings commercial-level grilling space and modern smart technology to the backyard. This 7-burner powerhouse combines six 304 stainless steel main burners with a high-output side burner to produce a massive 84,000 BTUs of cooking energy. The listing notes that while the smaller Denali 405 and 425 variants remain propane-only, the Denali 605 is fully dual-fuel compatible, connecting to natural gas when using the monument grills natural gas conversion kit model 97352 included in this bundle. This substantial fuel infrastructure feeds an expansive 895 square inches of total space, split into 640 square inches of primary grate area and a 225-square-inch upper warming surface.
Smart monitoring technology sets this model apart from analog grills. Integrated Bluetooth connectivity links the cookbox to your smartphone, enabling real-time temperature tracking and automated cook timers without requiring you to stand directly over the hot grates. A high-contrast LED screen on the front control panel displays current oven conditions alongside readings from a wired meat probe. Visual status cues extend to the control knobs, which feature color-coded backlighting that shifts from white when inactive to red for high heat and orange for low heat. The control illumination system can be powered using standard AA batteries or connected directly via a modern Type-C charging port. If you are accustomed to small-footprint cookers like a cuisinart tabletop grill, stepping up to this digital command station fundamentally changes how you organize high-capacity cooks.
The interior architecture includes porcelain-coated cast iron grates and an innovative multi-functional warming grid designed with dedicated slots to suspend chicken legs and whole peppers above the flames. The superior Clearview lid window spans the width of the hood, preserving consistent internal temperatures during low-and-slow roasting. Spanning 65.4 inches in depth by 23.3 inches in width and standing 48 inches tall, the Denali 605 is built for high-volume entertaining and ambitious menu planning. It stands out as the best monument gas grill for tech-focused outdoor cooks, yielding only to dedicated rotisserie bundles if standalone rotisserie motors and specialized griddle inserts take priority over natural gas compatibility.

Monument Grills 6+1 Burner Smart Propane
Monument Grills 6+1 Burner Smart Propane
Best for: Propane cooks seeking turnkey rotisserie packages
Pros
- Includes rotisserie pizza stone and cover bundle
- Dual ceramic sear zones reaching 700°F
- Smart Bluetooth app with dual meat probes
- Expansive 900 square inch cooking footprint
Cons
- Does not support natural gas plumbing
- Requires dedicated space for bundled accessories
The Monument Grills 6+1 Burner Smart Propane grill, designated as the Denali 605Pro, serves as the brand’s fully loaded culinary centerpiece. A critical technical detail in the listing specifies that the Denali 605Pro operates strictly on liquid propane and does not support natural gas plumbing. Backyard cooks deciding which monument gas grill to buy must note this structural limitation, as the 605Pro cannot be adapted with a conversion kit. In exchange for sticking exclusively to propane, this station provides an advanced 78,000 BTU burner array composed of five ThermaSear burners, one built-in ceramic sear burner, and an expansive ceramic sear station mounted on the side shelf that reaches 700°F in ten minutes.
Culinary versatility is enhanced by an extensive accessory suite bundled directly in the box. The package includes a motorized rotisserie kit with extra spit forks, a cordierite pizza stone, a round diamond searing grid, a heavy round cast iron cooking plate, two wired food probes, and a heavy-duty weather cover. Its 900-square-inch total cooking footprint accommodates up to 35 burger patties simultaneously across 640 square inches of primary enameled cast iron grates and a 260-square-inch warming rack. Cooks interested in flat-top griddling surfaces like a vevor flat top grill will find the bundled round cast iron plate useful for cooking smash burgers and breakfast items directly over the burner deck.
Monitoring is handled by Monument’s Bluetooth app platform, displaying dual meat probe telemetry and ambient firebox temperatures in real time on both your phone and the integrated digital dashboard. The brushed stainless steel cart measures 24 inches deep, 65 inches wide, and 46 inches high, delivering substantial presence and high thermal durability. While it delivers exceptional searing temperatures and turnkey rotisserie roasting, it immediately gives way to the standard Denali 605 or the 4+1 Burner Natural Gas model whenever a continuous patio natural gas supply is an absolute requirement.

Before You Buy
Installing a gas grill requires careful attention to your home patio fuel infrastructure. The product listings do not specify the exact operating water column pressure required for their natural gas manifolds, nor do they state the specific internal diameter of the supplied connection hoses. Connecting any natural gas appliance safely requires confirming that your exterior supply line matches standard residential delivery pressure and uses compatible quick-disconnect fittings. Furthermore, local residential building codes frequently dictate clearance distances between high-heat outdoor cookers and combustible siding, overhangs, or deck railings.
Logistical and operational details also require preparation before delivery day. For convertible listings that bundle the grill and conversion kit, the manufacturer notes that items ship in separate packages and may arrive on different dates, requiring you to pause final assembly until all components are present. In addition, the listings do not detail the maximum line-of-sight range for Bluetooth app pairing or specify battery life expectations for the digital consoles and illuminated knobs. Planning your outdoor kitchen around reliable power access and clear physical pathways will ensure a smooth assembly and setup process.
FAQ
Can all Monument gas grills run on natural gas?
No. Monument manufactures dedicated natural gas grills, dual-fuel convertible models, and propane-only units. For example, the M415BZNG operates exclusively on natural gas, while the Denali 605 supports both propane and natural gas via a conversion kit. Conversely, the Denali 605Pro listing explicitly notes that it only supports liquid propane and does not support natural gas.
What components are needed to convert a Monument grill to natural gas?
Converting an approved Monument dual-fuel model requires the Monument Grills conversion kit model 97352. This kit provides the necessary orifices and hardware to adjust gas flow from high-pressure propane to low-pressure residential natural gas lines. Always verify that your specific grill model explicitly supports dual-fuel conversion before attempting an installation.
How does the Clearview viewing window assist cooking?
The Clearview window built into the grill lid lets you monitor the browning and flare-up activity of your food without opening the hood. Opening a grill hood vents trapped radiant heat, lowering the internal cooking temperature and extending cook times. The viewing glass allows you to maintain stable ambient temperatures inside the cookbox while keeping visual track of your meal.
How are the LED knob lights and digital displays powered?
On Denali series grills, the control knob backlighting and digital temperature display consoles can be powered using standard AA batteries or connected to a power bank using an integrated Type-C port. The lights use color indicators to communicate burner activity, showing white when a burner is off, red during high-heat operation, and orange in low-heat mode.
What is the primary difference between the Denali 605 and the Denali 605Pro?
The critical difference lies in fuel compatibility and included accessories. The Denali 605 is a dual-fuel grill that can be converted to natural gas using kit 97352. The Denali 605Pro is strictly a propane grill that cannot be converted to natural gas, but it includes upgraded ceramic sear burners, a rotisserie kit, a pizza stone, a cast iron cooking plate, and a protective grill cover directly in the box.
