Specifications

Installation planning

• Cut-out: 53-1/4" W x 25" D x 15" H.
• The island must be built from non-combustible material. In a combustible island an American Made Grills grill liner is required: the GL-HYB54.
• Side and rear clearances: at least 4" from a non-combustible wall or backsplash, 14" from a protected combustible wall (a non-combustible face over a combustible wall), and 18" from a combustible wall. The 4" backsplash clearance has to be met before any wall behind it.
• Keep at least 5 feet between the countertop and any overhead construction, and never install under unprotected combustible overhead construction. Under combustible overhead construction the cooking area must be covered by an exhaust hood larger than the cooking area and moving at least 1,200 CFM; under non-combustible overhead construction a hood is highly recommended.
• Outdoors only. Never use it in a garage, building, shed, breezeway or other enclosed area, or in or on a recreational vehicle or boat.
• Gas supply pressure: natural gas 4" to 7" water column, propane 11" to 14" water column. Natural gas models use the supplied regulator set to 4" w.c.; propane models use an LP regulator set to 11" w.c. Never connect the grill to an unregulated supply.
• Size the gas line for the total BTU of every appliance on it, never smaller than 1/2" inside (1" outside) diameter, and keep it as short as possible: pressure drops with distance and with every elbow or tee. Running a grill and a side burner from one line takes a tee fitting (not supplied). Don't put tape, pipe dope or thread compound on flare fittings. American Made Grills recommends a licensed gas professional for all gas plumbing; a "T"-handle manual shut-off valve is required on permanent gas lines (Massachusetts requires a licensed plumber or gas fitter).
• Propane: use a standard 20 lb DOT cylinder with a Type 1 (QCC-1) valve and an overfill prevention device, no larger than about 12-1/4" across and 18" tall (not included). Never fill it past 80%, never store a spare cylinder under or near the grill, and keep cylinders outdoors, upright and away from heat. Propane is heavier than air, so vent an enclosure on opposite sides near the bottom.
• Leak-test every connection with 1 part soap to 3 parts water before first use and after every cylinder change. Growing bubbles mean a leak: shut off the gas and fix it before use. Never test with a flame.
• Level it in every direction; a grill out of level burns erratically and heats unevenly.
• Power: the lights, ignition and optional rotisserie motor need a 120 V, 60 Hz, 15 A GFCI-protected outdoor outlet installed by a qualified electrician; the grill must be electrically grounded.
• Weight: these grills ship at 250 lb or more, and the largest at over 400 lb. Plan for at least two people, and lift it by the frame, never the hood.
• The grill draws air in at the front and vents out the back of the hood. Don't grill with wind blowing into the rear: the control panel and knobs can get very hot.
• Keep stainless steel away from construction dust (stone dust, stucco, lime) and pool chemicals, which can permanently discolor it. Note visible box damage on the delivery receipt, and report hidden damage to the carrier within 5 days, keeping the carton.

Use and care

Light gas burners with the hood open. For charcoal or wood, keep the hood open while the fire starts, use the grate lifting tool to load or move the fuel trays (never with your hands on a hot grill), and never fill the trays past their rim: an overfilled tray overheats the grill, and that damage is not covered by the warranty. Use the adjustable hood vents to control airflow when smoking or cooking with charcoal and wood. Empty the trays and the drip tray once the grill is cold; the drip tray has a drain plug for oils and liquids, and should be checked for rain water before you pull it out. Clean clogged burner ports with a wire or brush, and check the burners, venturis and orifices at least once a year, since debris or insects can block them during long periods of non-use. Clean the stainless steel along the grain with a stainless steel cleaner, never metal abrasives, and keep the grill covered when not in use.
