Blaze Premium LTE+ 32-Inch 4-Burner Built-In Gas Grill (Natural Gas or Propane) - BLZ-4LTE3

Features

• 66,000 BTU total: four 14,000 BTU cast stainless steel burners plus a 10,000 BTU infrared rear burner for rotisserie cooking.
• 715 sq. in. of cooking space: 531 sq. in. main grid in four zones, separated by removable heat zone separators, plus a 184 sq. in. warming rack.
• 9 mm triangular searing rods: Blaze's patented stainless steel rods for defined sear marks, over flame-stabilizing grids that limit flare-ups.
• Spring-assisted, double-lined hood: easier to lift and lower, and the double wall resists heat discoloration and holds heat.
• Night-ready lighting: red LED-backlit knobs and automatic halogen interior lights.
• Dependable ignition: Push N' Turn flame-thrower ignition, with a flash tube and crossover channels as backup.

Specifications

Installation planning

• Cut-out: 30-5/8" W x 21-1/4" D x 8-1/2" H. Overall size: 32-1/2" W x 25-3/4" D x 21-1/4" H. The manual shows the extra room the hood needs to open.
• Build into a non-combustible enclosure, or use a Blaze insulated jacket. Cut a 1" air gap in the front face of the countertop below the control panel.
• Clearances: 18" from combustible construction at the sides and back; 4" from non-combustible construction. Never install under combustible overhead construction. Under a non-combustible overhead, keep 72" and run a UL-listed vent hood of at least 1,000 CFM that is larger than the cooking area, with the fan bottom 36" above the cooking surface.
• Island vents on both sides: propane (heavier than air) needs lower vents with their bottom within 1" of the island floor and top no more than 5" up, each at least 1/2 sq. in. of free area per lb of stored fuel; natural gas needs upper vents within 5" of the island top, each at least 1 sq. in. per lb of stored fuel. Openings must admit a 1/8" rod and stay unobstructed.
• Propane: one standard 20 lb cylinder (12-1/4" diameter x 18" high, with overfill protection device) at a time; connect the 3/8" flare hose fitting with a wrench and no pipe sealant. Natural gas: Blaze recommends a flex connector of at least 5/8" diameter, run to the regulator at the rear right corner, with an accessible shut-off valve.
• Electrical: mount a 15-amp outlet on a GFI-protected breaker inside the island (back wall); the light transformer plugs into it. Outdoor-rated extension cords only.
• Two people should lift the grill into the cut-out; check it sits level and is supported around its full edge (non-combustible shims if needed). A permit may be required. Fuel conversion (LP to NG or back) is done only by a licensed gas professional: new orifices on each burner plus the regulator pin.
• With an insulated jacket: a licensed contractor installs it, gas connections inside it use a stainless steel flex line (never a rubber hose), and the grill's own clearances above, behind and beside still apply.
• Leak-test every connection with soapy water before first use and whenever a connection changes; never use a flame.

Care: Inspect and clear the burner tubes before each use (insects can nest in them and cause a flashback). Flames should be mostly blue and not lift off the burner; the air shutter is set about 1/8" open for natural gas and 1/4" for propane. After each cook, brush the grates on medium-high, wipe them with a 50/50 vinegar and water solution, then dry and oil lightly; empty and wash the drip tray once cool and never cook without it. Clean stainless steel with the grain using a non-metallic pad, never flood a hot grill with cold water, and cover it only when cool and dry.

Warranty

Blaze lifetime warranty (parts only) on the main burners, cooking grids, body, flame tamers, heat zone separators, warming rack and control valves; 1 year (parts only) on ignition, electrical and lighting components, from the purchase date. For multi-user use, Blaze covers the stainless steel housing, burners, rod grids, brass valves, liners and manifolds for 3 years and other parts (except burners) for 90 days; restaurant use is not covered.

The warranty covers the original owner at the original installation site in the United States and Canada and is not transferable. Register the grill with Blaze within 30 days of purchase and keep your receipt. Labor, shipping and diagnostic charges are not covered, and discoloration or surface rust is excluded unless structural integrity is lost. Improper installation, unqualified repairs or unapproved alterations void the warranty. Full terms are in the grill manual below.

Frequently asked questions

Does the Blaze BLZ-4LTE3 come in natural gas?

Yes. Order BLZ-4LTE3-NG for natural gas (it ships with a regulator set to 4" water column) or BLZ-4LTE3-LP for propane (it ships with the LP hose and regulator). Converting later is a job for a licensed gas professional: new orifices on each burner plus the regulator pin.

What is the difference between the BLZ-4LTE2 and the BLZ-4LTE3?

Both are 32-inch, 4-burner Premium LTE grills with 14,000 BTU burners, a 10,000 BTU infrared rear burner and the same 30-5/8" x 21-1/4" x 8-1/2" cut-out. The LTE+ (BLZ-4LTE3) adds a spring-assisted hood, red LED-backlit knobs and halogen interior lights that turn on automatically.

How many BTUs and how much cooking space does this 4-burner Blaze grill have?

66,000 BTU in total (four 14,000 BTU burners plus the 10,000 BTU rear burner) and 715 sq. in. of cooking space: a 531 sq. in. main grid that Blaze rates at up to 18 burgers, plus a 184 sq. in. warming rack.

Can I use the Blaze LTE+ 32 as a freestanding grill?

Yes. The same grill head drops into the Blaze 4-burner grill cart (BLZ-4-CART-SC). In an island, the enclosure must be non-combustible, or fitted with a Blaze insulated jacket for 32-inch 4-burner grills; please confirm the jacket model with us before ordering.
