How to assemble a gas grill

A gas grill (barbecue) arrives as a cart, a firebox, burners, grates and a hose and regulator. The build is straightforward; the one step you must never skip is the leak test with soapy water before the first light.

Tools needed

  • Cross-head screwdriver
  • Spanner or adjustable wrench
  • Small brush and a cup of soapy water
  • Work gloves

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Cart sides, base panel and wheels
  • Firebox with burners and control knobs
  • Side shelves and lid
  • Cooking grates and flame tamers
  • Hose, regulator and hose clips

Step by step

  1. Step 1: Build the cart: sides to the base panel, then the wheels and the back panel, keeping bolts snug but not fully tight.

  2. Step 2: With a helper, lift the firebox onto the cart and bolt it in place, then tighten the whole cart.

  3. Step 3: Fit the side shelves, handles and any side burner.

  4. Step 4: Check the burners sit correctly over the gas valve outlets, then fit the flame tamers and cooking grates.

  5. Step 5: Connect the hose and regulator to the gas cylinder and the grill, using a regulator suited to your gas type.

  6. Step 6: Leak test: with all knobs off, open the cylinder valve and brush soapy water on every joint. Bubbles mean a leak: close the gas and fix it before use.

  7. Step 7: Light the grill with the lid open, following the manual, and run it for 15 to 20 minutes to burn off manufacturing oils.

Common mistakes

  • Skipping the leak test.
  • Fitting the burners so they miss the valve outlets, which gives an uneven or yellow flame.
  • Lighting the grill with the lid closed.

Safety notes

  • Leak test every time you connect a cylinder; never use a flame to look for leaks.
  • Use the grill outdoors only, away from walls, fences and overhanging branches.
  • Store the gas cylinder upright and outdoors.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
