Dyna-Glo 4-Burner Gas Grill – Commercial-Grade Outdoor Cooking
Our 4-burner gas grill combines professional-grade heat control with a spacious cooking surface for families and weekend entertainers. Four stainless steel burners deliver 48,000 BTU total output, giving you independent temperature zones for searing steaks on one side while slow-cooking vegetables on the other.
Porcelain-enameled cast iron grates retain heat evenly and create restaurant-quality sear marks on everything from burgers to bone-in chicken. The 644-square-inch total cooking area includes a 484 sq. in. primary surface plus a 160 sq. in. warming rack, so you can finish sides while proteins rest. We built the firebox from heavy-gauge steel with a durable powder-coat finish that stands up to rain, heat, and years of use.
- 48,000 BTU total heat output across four independent burners
- 644 sq. in. total cooking area: 484 sq. in. primary + 160 sq. in. warming rack
- Porcelain-enameled cast iron cooking grates for superior heat retention
- Stainless steel burners with electronic ignition system
- Built-in temperature gauge for precise heat monitoring
Burner Configuration & Heat Control
Each of the four stainless steel burners operates independently, so you create multiple heat zones in a single cook session. The left two burners might run at high heat for searing ribeyes while the right side stays at medium-low for delicate fish fillets.
Total output reaches 48,000 BTU, distributed evenly across the 484-square-inch primary cooking surface. Electronic ignition lights each burner with a single push — no matches, no hassle. The built-in lid thermometer gives you real-time temperature feedback, though we recommend using a probe thermometer for precision on thick cuts.
Cooking Surface & Grate Design
Porcelain-enameled cast iron grates hold heat longer than standard steel, which means better browning and those coveted crosshatch marks. Cast iron also distributes heat more evenly, eliminating the hot spots that char one side of a burger while leaving the other pale.
The 484-square-inch primary grate accommodates roughly 24 burger patties or eight full racks of ribs laid flat. Above that sits a 160-square-inch chrome-plated warming rack — perfect for toasting buns, holding finished proteins, or slow-roasting bell peppers while the main event cooks below. Total capacity of 644 square inches handles family gatherings without crowding.
Cabinet & Shelf Layout
Side Shelves
Two fold-down side shelves provide 12 inches of prep space on each flank of the grill. Use the left shelf for raw proteins and marinade bowls, the right for finished platters and sauces. Both shelves are powder-coated to match the main cabinet and include integrated tool hooks.
Storage & Grease Management
The enclosed cabinet below the firebox stores a 20 lb. propane tank, plus extra room for grill tools, wood chip boxes, and seasoning containers. A slide-out grease tray sits beneath the firebox, catching drippings in a removable pan you can line with foil for faster cleanup. The tray design channels grease away from the burners, reducing flare-ups and extending burner life.

Common Questions About the 4-Burner Gas Grill
This grill operates on a standard 20 lb. liquid propane tank, the same size used by most residential gas grills. The enclosed cabinet is designed to hold the tank upright and secure it with a retention strap.
A full 20 lb. tank provides approximately 25 hours of cooking time at medium heat with all four burners running. Actual runtime varies based on your temperature settings and cooking habits.
Yes, Dyna-Glo offers a natural gas conversion kit sold separately. The kit includes a natural gas regulator, extended hose, and replacement orifices calibrated for NG pressure and flow rates.
Installation requires removing the LP regulator and swapping out each burner orifice. We recommend hiring a licensed gas technician to perform the conversion and ensure compliance with local building codes.
The 484-square-inch primary grate accommodates approximately 24 standard quarter-pound burger patties arranged in rows. If you use the 160-square-inch warming rack for buns or finished patties, you can stage multiple batches efficiently.
For mixed cookouts, you might fit 16 burgers on the main grate alongside ears of corn or chicken breasts, using the warming rack for sides.
The grates are porcelain-enameled cast iron. Cast iron retains and distributes heat more evenly than standard steel, which produces better searing and consistent cooking across the entire surface.
The porcelain enamel coating protects the cast iron from rust and makes cleanup easier. You'll still want to brush the grates after each use and apply a light coat of cooking oil periodically to maintain the finish.
No, a cover is sold separately. We offer a heavy-duty polyester cover specifically designed to fit all Dyna-Glo 4-burner and 5-burner models.
The cover features UV-resistant fabric, reinforced seams, and an adjustable drawstring hem. Using a cover extends the life of the grill by protecting the finish, burners, and ignition system from rain, snow, and UV exposure.
Most customers complete assembly in 60 to 90 minutes with two people. The process involves attaching the cart legs, mounting the firebox, installing burners and grates, and connecting the side shelves.
All hardware is included and pre-sorted by assembly step. You'll need a Phillips screwdriver, an adjustable wrench, and needle-nose pliers. The instruction manual includes exploded diagrams and step-by-step photos.
The four stainless steel burners produce a combined 48,000 BTU. Each burner operates independently, so you can run one burner at 12,000 BTU for low-and-slow cooking while another runs at full output for searing.
This heat output is ideal for grilling over a range of temperatures and cooking methods — from slow-roasting whole chickens to flash-searing tuna steaks.
