Features
- 12,000 BTU cast brass burner: holds heat well for steady simmering of sauces, soups and sides.
- Shallow drop-in: only 4-1/2" tall in a 2-13/16" deep cutout, resting on its frame lip for a clean island install.
- Push-and-turn ignition: piezo ignition with a flash tube backup, plus manual lighting with a long lighter if needed.
- LTE+ styling: LED backlit knobs (per Blaze's product page) show when gas is on and match the LTE+ collection.
- Stainless steel cover: shields the burner from rain and debris between uses.
- Lifetime coverage on the core: burner, grate, body and valve carry a Blaze lifetime warranty (parts) when registered.

Installation planning
- Cut-out: 11-1/4" W x 18" D x 2-13/16" H, no larger than the burner's outer frame. The burner rests on its frame lip and must be level and supported around its whole edge (use non-combustible shims if needed). The manual notes that notching the two front countertop edges will be necessary.
- Enclosure: non-combustible materials only, or a Blaze insulated jacket in a combustible island; the local fire marshal or building inspector makes the final call. Lift it with two people.
- Clearances: 18" from combustible construction at the sides and back. Never install under combustible overhead construction or an awning. Under a non-combustible overhead, keep 72" with a UL-approved vent hood of at least 1,000 CFM that is larger than the cooking area, its fan bottom 36" above the cooking surface.
- Vent the island on both sides: propane vents within 1" of the island floor (no more than 5" high, at least 1/2 sq. in. of free area per lb of stored fuel, per vent) and natural gas vents within 5" of the island top (at least 1 sq. in. per lb, per vent). Every opening must pass a 1/8" rod and stay clear. Keep only one cylinder in a base cabinet.
- Outdoors means up to three walls with no roof, or a roof with no more than two walls. Not for garages, enclosed areas, RVs or boats, or near a window or vent into the house. Protect it from rain and wind; a wind block may be needed.
- Natural gas: the regulator is factory-set for 4" water column at the rear right corner; use a flex connector of at least 5/8" diameter and seal non-flared fittings with gas-rated sealant. Inlet pressure above about 1/2 psi needs another regulator first. The installer supplies an accessible manual shut-off valve.
- Propane: connect only the factory hose and regulator (3/8" flare, no pipe sealant on the flare) to a standard 20 lb cylinder with an overfill prevention device. For plumbed (bulk) propane at 11" water column, a licensed gas professional resets the convertible regulator; Blaze says not to use that converted regulator with a 20 lb cylinder.
- Qualified installer only: a licensed gas professional or your gas company. Permits may be required; Massachusetts requires a licensed plumber or gas fitter and a T-handle shut-off. Fuel conversion (orifice change with a 6 mm socket, regulator pin) is for a licensed gas professional; set the air shutter about 1/8" open for natural gas and 1/4" for propane.
- Leak-test every joint with a 1:1 soap and water solution before each use and after any change; never use a flame. To light: remove the cover, push the knob in and turn it to HIGH; 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: Check the burner tube for spiders and debris before each use. Wipe the grid with a rough cloth once cool; for cooked-on food use a 50/50 water and vinegar mix with a Scotch-Brite pad along the grain, rinse, dry and oil it lightly while still warm. Clean the stainless body with mild dish soap and warm water along the grain, dry with microfiber and finish with a stainless polish; avoid harsh abrasives, never pour cold water on a hot grate, and never cover the burner while it is damp or warm.
Warranty
Blaze lifetime limited warranty, residential use, parts only: lifetime on the main burner, grate, body and valve and the other stainless steel components, and on flame stabilizers; 1 year on ignition and on lighting and electrical parts. For multi-user installations (apartments, hotels, fire stations), Blaze covers the stainless housing, burners, rod grids, brass valves, inner liners and manifolds for 3 years and other parts (except burners) for 90 days; restaurant use is not covered. Coverage is for the original owner at the original delivery site in the United States and Canada and does not transfer. Register with Blaze within 30 days of purchase and keep your receipt.
Not covered: labor, shipping, handling and diagnostic charges, installation problems, discoloration and surface rust (unless structural integrity is lost), and damage from chlorine, fertilizers, chemicals, salt, excess humidity, high cooking temperatures or poor maintenance. Service by an unqualified person voids the warranty. Call Blaze before calling a service provider. Full terms are in the user manual.
