Fire Magic Aurora Size Guide: 24″–46″ Built-In

Before you commit to an Aurora size, measure the opening you have to work with — or, if you're framing a new island, the opening you intend to build. Three dimensions decide whether the head will drop in:

• Width. Side-to-side along the front face of the island. The grill head drops in from above. Cutout width: 25½″ (A430i 24″), 32″ (A540i 30″), 31¼″ (A660i 30″), 37″ (A790i 36″), 50¼″ (A830i Combo 46″). Note: the A540i and A660i are both 30″ but use different cutouts because they sit on different chassis depths.
• Depth. Front-to-back from the inside of the front island wall to the inside of the back wall. The Aurora lineup splits two depths. A430i, A540i, and A830i Combo: 19½″ cutout depth. A660i and A790i: 23½″ cutout depth (deeper hood, larger cooking surface).
• Height (drop). Top-of-counter down to the bottom of the island enclosure. Cutout height is 11½″ across the entire Aurora lineup. This is the depth of the head body that hangs into the island below the counter line.

Beyond the cutout itself, also confirm the clearance envelope around the island: 18″ minimum from each side of the grill to any combustible material, 4–18″ from the rear depending on rear-wall construction, 24″ from any corner wall, and a 120VAC GFCI-protected outlet within reach for the ignition system and halogen lights. The Clearances section below covers each scenario.

Cutout dimensions for each Aurora built-in head, sourced from the Fire Magic Product Specifications Guide and per-model owner's manuals. All dimensions assume a non-combustible enclosure; if installing in a combustible enclosure, an approved Fire Magic insulating liner is required (sold separately) and the cutout dimensions change.

Overall head dimensions sit larger than the cutout because the head includes the hanger flange that rests on the counter. Use the cutout dimensions above for framing the rough opening; use the overall dimensions below to verify counter footprint and surrounding clearances:

Per the Fire Magic owner's manual, every Aurora built-in must maintain the minimum clearances below. The clearances differ by what the grill is adjacent to — non-combustible material (brick, masonry, properly rated stainless steel, concrete) gets shorter clearances; protected or unprotected combustible material requires more space.

Side wall clearance applies to any wall on either side of the grill. Corner walls need extra space (24″) to account for airflow variables that affect performance. Cooling appliance clearance (14″) covers refrigerators and kegerators; heating appliance clearance (12″) covers adjacent built-in pizza ovens and griddles.

If a non-combustible backsplash is installed, it must have a minimum 4″ clearance from the rear of the unit. Vent openings in the enclosure must maintain 6″ minimum clearance between each opening and 2″ minimum clearance from any items within the enclosure.

An additional regulator may be needed to meet these inlet pressure ranges depending on the supply system. The grill ships with a C.S.A. approved stainless steel flex connector pre-installed to the valve manifold, with a flare-to-NPT adapter for ½″ pipe.

• Gas supply pipe must be ½″ minimum interior diameter.
• If the gas line is longer than 20 feet, a larger diameter line may be necessary — refer to NFPA 54 guidelines.
• A manual shut-off valve is required in the supply line within 6 feet of the unit, and must be easily accessible.
• Use pipe joint compound resistant to all gases on NPT pipe fittings (not on flare fittings).
• Do not use rubber hose within the enclosure.
• A sediment trap is recommended downstream of the shut-off valve.

Size the supply line based on the peak demand of the grill plus any other appliances drawing from the same supply (range, water heater, dryer, fire feature, side burner). The A830i Combo's charcoal igniter is gas-fed (used to ignite charcoal); after ignition, the charcoal side runs without gas demand.

The grill and its individual shut-off valve must be disconnected from the gas supply piping during any system pressure testing at test pressures in excess of ½ PSI (3.5 kPa). The grill must be isolated from the gas supply piping by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSI.

Every Aurora grill requires 120VAC / 15A service within the enclosure for the Push-to-Light Hot Surface Ignition system, the analog thermometer backlight, and the internal halogen lights. The Magic View Window option (available on A660i and A790i) does not change the electrical requirement.

• Use only a Ground Fault Circuit Interrupter (GFCI) protected three-wire grounded receptacle, rated 15 AMP minimum.
• The grill must be electrically grounded in accordance with local codes, or NFPA 70 (National Electrical Code) where local codes are absent.
• Mount the outlet within reach of the grill enclosure.
• Keep the supply cord away from heated surfaces; unplug the grill before cleaning.
• Use only extension cords with a three-prong grounding plug, rated for the equipment, and approved for outdoor use with a W-A marking.

On the A830i Gas/Charcoal Combo, the halogen interior lights, the rotisserie backburner (when equipped — "8" SKU), and the charcoal igniter electrical connection are all located on the gas side of the grill only. Plan the 120V outlet on the gas-side end of the cutout. The charcoal side has no electrical components.

If the grill is installed in a built-in island and the fuel is propane, the Fire Magic owner's manual requires a separate, isolated enclosure for the LP gas cylinder. The enclosure must:

• Contain a single LP cylinder (no spare cylinder stored alongside the in-use cylinder).
• Isolate the cylinder from the burner compartment with a non-combustible heat shield, a flame barrier, and protection from foreign material such as hot drippings.
• Provide vent register openings at the top and bottom of the enclosure to allow propane vapor (heavier than air) to escape if a leak occurs and to allow combustion air to circulate.
• Make the cylinder reachable for swap-out without reaching into the heat zone behind the grill.
• Include a means of cylinder retention so the cylinder cannot tip or move.

Plan a code-compliant access door for cylinder swap-out. Maintain a 6″ minimum clearance between vent openings and a 2″ minimum clearance between vents and other items inside the enclosure.

The cutout dimensions in the table above assume a non-combustible enclosure. If you are framing a wood or other combustible enclosure, an approved Fire Magic insulating liner is required (sold separately) — and the cutout dimensions change to accommodate the liner thickness. Refer to the liner instructions for the adjusted cutout. Pre-fabricated outdoor kitchen islands designed for built-in gas grills typically meet the non-combustible requirement.

Per the Fire Magic owner's manual: the enclosure must be installed on a hard and level surface, must be properly vented, must have a non-combustible countertop, and must allow access to the interior for installation and service. The grill is supported by the stainless steel hanger extending from the upper portion of the unit (resting on left, right, and back of the cutout) plus the two front support adjustment bolts located below the control panel.

The 46″ A830i Combo has a single 50¼″ wide cutout — the gas and charcoal sides share one rough opening. Plan the LP cylinder enclosure on the gas-side end of the island so the supply line runs to the gas valve manifold, not the charcoal compartment. Charcoal accessories (charcoal pan, ash management, lump charcoal storage) sit independent of the LP enclosure.

If the countertop extends beyond the front wall (creating a countertop overhang), the overhang must be cut flush with the front wall for the width of the control panel — or a gap will be created exposing the forward portions of the firewalls. Maintain ¼″ clearance around the control panel for removal and service.

Substrate added to the enclosure front wall (tile, stone, etc.) sitting flush behind the control panel must be accounted for in the front-to-back cutout depth. Substrate alongside the control panel does not need to be considered in the cutout depth, but a ¼″ clearance on each side is required.

The Fire Magic warranty applies to the original purchaser at the original installation address and to single-family residential use only. Coverage is voided for grills installed in commercial, rental, or non-residential applications. See the Warranty section of the comparison guide for the full tier table.
