Grill Clearances and Outdoor Kitchen Layout: What the Manual Says

Grill manuals set minimum distances, and they differ from one model to the next. Each figure below is taken from the owner’s manual named in the sources. Practical advice: use this guide to read your own manual, not in place of it. The last two sections cover outdoor kitchen layout and its limits. Figures and quotes from the manuals are attributed to them; the rest is practical advice. For the choice between fuels, see our gas versus charcoal comparison.

Distances stated in each manual

  • Weber US grill owner’s guide (document 48990): never operate within 24 inches (61 cm) of any structure, combustible material, or other gas cylinder.
  • The same guide sets 25 feet (7.5 m) from any flammable liquid.
  • Weber Go-Anywhere LP guide (document 48601): never operate within 10 feet (3.0 m) of any structure, combustible material, or other gas cylinder.
  • That guide also sets 25 feet (7.5 m) from any flammable liquid.
  • Weber Q 1000 to Q 2200 guide (document 71728): do not use within 610 mm (2 feet) of any combustible material.
  • That guide counts wood or treated-wood decks, patios, and porches as combustible.
  • Weber built-in gas barbecue installation guide, E-360, S-360, E-460 and S-460 (Australia and New Zealand edition): do not use within 61 cm (24 inches) of combustible materials, including the top, bottom, back, and sides.
  • Napoleon Rogue 525 Series manual: maintain 18 inches (460 mm) to the rear and 7 inches (180 mm) to the sides from combustibles.

Overhead cover and enclosed spaces

Weber’s US guide rules out enclosed spaces and overhead combustible construction, saying: “Do not use in a garage, building, breezeway, tent, any other enclosed area or beneath overhead combustible construction.” The Napoleon Rogue 525 manual says: “Do not operate unit under overhead combustible construction.” It adds screened-in porches and gazebos to its list of enclosed areas. Weber’s Q guide says a grill “must never be used under an unprotected combustible roof or overhang.” For built-ins, the Weber installation guide says the barbecue “must not be installed under overhead combustible construction.”

Surfaces and built-in cutouts

Weber’s Go-Anywhere guide says: “An asphalt surface (blacktop) may not be acceptable for this purpose.” For built-in installs, the Weber guide says: “The cut-out structure, countertops, and adjacent work … areas for the Built-In barbecue installation must be built from noncombustible materials only.” If you are unsure which materials count as noncombustible, the same guide says to “contact your local building materials supplier or fire department.”

What the safety agencies add

The CPSC’s 2011 grilling release says: “Gas and charcoal grills present a risk of fire and/or carbon monoxide poisoning that could result in injury or death.” The CDC’s carbon monoxide page says: “CO can build up indoors and poison people and animals who breathe it.”

Outdoor kitchen layout (practical advice)

  • Practical advice: treat each manual figure as a minimum, and leave room for the lid, side shelves, and any hood.
  • Napoleon’s Rogue 525 manual says: “Additional clearance is recommended near vinyl siding or panes of glass.”
  • The Napoleon built-in manual gives 24 inches (610 mm) for that case.
  • The Weber US guide says: “Never operate this appliance within 24 inches (61 cm) of any structure, combustible material or other gas cylinder.”
  • Practical advice: keep spare cylinders outside that distance, not beside the grill.
  • Practical advice: plan a clear path out of the area, and keep cords, chairs, and carts off it.
  • For winter storage, see our guide to how to store and winterize your grill.

Limits and common mistakes

  • Practical advice: check the model number and revision in your manual before you use any figure here.
  • The Rogue 525 manual gives 18 inches to the rear and 7 inches to the sides.
  • Practical advice: measure the rear and each side separately, and use the figure for each direction.
  • The Napoleon built-in manual says: “The cabinet frame and the cabinet MUST be made from non-combustible material when the appliance is not installed with the Zero Clearance Liner corresponding to your unit.”
  • Practical advice: confirm the liner for your unit before you build a surround.
