Features
- Two 12,000 BTU brass burners: run one for a simmer or both at once, each on its own knob.
- Compact 12-1/2" width: adds two burners while taking little counter space from the island.
- LTE+ lighting: LED backlit knobs with safety glow that show when gas is flowing, for safe cooking after dark.
- Removable stainless steel cover: keeps rain and debris off the burners between uses.
- Push-and-turn ignition: piezo ignition with a flash tube backup, plus manual match-lighting if needed.
- Lifetime coverage on the core: burners, grates, body and valves carry a Blaze lifetime warranty (parts) when registered.

Installation planning
- Cut-out: 11" W x 20-3/4" D x 8-1/2" H. Cut a 1" air gap in the front face of the countertop below the control panel.
- Install in a non-combustible enclosure only; the local fire marshal, building inspector or authority having jurisdiction decides what counts as combustible. A combustible island needs a Blaze insulated jacket.
- Clearances: 18" from combustible material at the sides and back. Never install under combustible overhead construction or an awning. Under a non-combustible overhead, keep 72" of clearance and run a UL-approved vent hood of at least 1,000 CFM that covers the cooking area, with the fan bottom at least 36" above the cooking surface.
- Vent the island on both sides: upper vents within 5" of the island top (at least 1 sq. in. of free area per lb of stored fuel, per vent) and lower vents within 1" of the floor and no more than 5" high (at least 1/2 sq. in. per lb, per vent). Every opening must pass a 1/8" rod. Propane is heavier than air and natural gas is lighter, so both vent levels matter.
- Outdoors means up to three walls with no roof, or a roof with no more than two walls, all openings permanently open; windows, doors and screens do not count. Not for garages, enclosed areas, RVs or boats, and not near a window or vent into the house. In a windy spot, use a wind break: wind from the rear can push heat behind the control panel.
- Natural gas: the regulator is factory-set for natural gas at 4" water column; use a flex connector of at least 5/8" diameter at the rear right corner, and seal non-flared fittings with rated thread sealant. Inlet pressure above about 1/2 psi needs another regulator first. The installer supplies an accessible shut-off valve.
- Propane: a 20 lb cylinder (12-1/4" diameter x 18" high, with an overfill prevention device) uses the factory LP hose and regulator only (3/8" flare, no pipe sealant; hand-tighten the regulator to the cylinder). Keep only one cylinder in the island, upright. Plumbed (bulk) propane at 11" water column requires a licensed gas professional to reset the convertible regulator; never use that regulator with a 20 lb cylinder.
- Fuel conversion (orifice change, regulator setting, air shutter about 1/8" open for natural gas and 1/4" for propane) is for a licensed gas professional only.
- Electrical: plug the light transformer into a 15-amp GFI-protected circuit; outdoor extension cords must be rated "W" or "W-A" and kept off hot surfaces.
- Leak-test every connection with a 1:1 soap and water solution before each use, after installation and whenever a connection changes. Never use a flame to check for leaks.
- Lighting: remove the cover, push the knob in and turn it to HIGH until it clicks. If it does not light within 5 seconds, turn it off and wait 5 minutes before trying again. Flames should be mostly blue and not lift off the burner.
Care: Clean the grate after every use while it is still warm: brush it, wipe it with a 50/50 vinegar and water solution, dry it with a microfiber cloth and oil it lightly. Wash the drip tray in hot soapy water once cool. Wipe stainless steel along the grain with a stainless steel cleaner and avoid harsh abrasives. Never flood a hot unit with cold water, and never cover it while damp or warm.
