Specifications

Installation planning

• Cut-out: 23-1/4" W x 21-1/4" D x 8-1/2" H. After cutting the cavity, cut a 1" air gap in the front face of the counter below the control panel. Overall size: 25" W x 25-3/4" D x 21-1/4" H. The grill rests on its frame lip and must be level and supported around the outer edge; use non-combustible shims if needed. Two people should lift it into place. An outdoor kitchen may need a permit.
• Build into a non-combustible enclosure, or use a Blaze insulated jacket when the island is combustible. Your local fire marshal or building authority decides what counts as non-combustible.
• Clearances: keep the side and rear clearances to combustible construction shown in the BCM manual, and 4" from non-combustible construction. Never install under combustible overhead construction, an awning or an overhang, or near a window or vent into the house. Under a non-combustible overhead, Blaze requires 72" of clearance and a UL-listed vent hood with the fan bottom 36" above the cooking surface.
• Outdoors only: no roof with up to three permanently open walls, or a roof with two permanently open walls; screens, windows and sliding doors do not count as open. Not for garages, RVs or boats. Use a wind guard or block in consistently windy spots.
• Island vents on both sides: upper vents no more than 5" from the island top with at least 1 sq. in. of free area per lb of stored fuel, and lower vents within 1" of the island floor (top no more than 5" up) with at least 1/2 sq. in. per lb. Propane is heavier than air and natural gas rises. Openings must admit a 1/8" rod and stay unobstructed.
• Propane: use the factory hose and regulator and one 20 lb (5 gal) cylinder at most (12-1/4" diameter x 18" high, with overfill prevention device), stored upright; hand-tighten the regulator to the cylinder and connect the 3/8" flare fitting with no pipe sealant. Natural gas: a flex connector of at least 5/8" diameter to the regulator at the rear right corner, gas-rated sealant or tape on non-flared fittings, and an accessible shut-off valve supplied by the installer. Supply pressure above 1/2 psi needs an additional regulator.
• Fuel conversion (LP to NG or back) is done only by a licensed gas professional: new orifices on each burner (6 mm socket, do not over-tighten) plus the regulator's conversion pin. Leak-test every joint outdoors with a 1:1 soap and water solution before each use and whenever a connection changes; never use a flame.
• Lighting: open the hood, push in a knob and turn it counterclockwise to HIGH; if a burner does not light within five seconds, turn it off and wait five minutes before trying again. Never light with the hood closed.

Care: Preheat with the lid closed for 10 to 15 minutes; the knobs are sensitive, and about 1/8 turn can move the temperature 50 to 75 degrees F. Flames should be mostly blue; the air shutter is set about 1/8" open for natural gas and 1/4" for propane. Check the burner tubes for spider webs and nests before use: a whooshing sound means flashback, so shut the grill off, let it cool and clean the burner. Scrape the grates while warm, wipe them with a 50/50 vinegar and water solution or a non-metallic scouring pad along the grain (Bar Keepers Friend for heavier grease), then oil them lightly. Wash the drip tray in hot, soapy water after each use, never cook without it in place, and never flood a hot grill with water. Cover the grill only when it is cool and dry.

Warranty

Blaze lifetime limited warranty on stainless steel components and flame stabilizers, and lifetime (parts only) on the main burners, grill grates, body and valves; 1 year (parts only) on ignition, lighting and electrical components. For multi-user settings (apartment complexes, hotels, condos, fire and police stations and other multi-family dwellings), Blaze covers the stainless steel housing, burners, rod grids, brass valves, inner liners and manifold for 3 years and all other components except burners for 90 days; restaurant use is not covered.

Coverage is for the original owner at the original installation site in the United States and Canada and is not transferable. Register the grill at blazegrills.com within 30 days of purchase to validate the warranty, and keep your receipt. Labor, shipping and diagnostic charges are not covered; discoloration or surface rust is excluded unless structural integrity is lost, as is damage from chlorine, salt, fertilizers or other chemicals. Incorrect installation voids the warranty. Full terms are in the BCM manual below.
