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.

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
Step 1: Build the cart: sides to the base panel, then the wheels and the back panel, keeping bolts snug but not fully tight.
Step 2: With a helper, lift the firebox onto the cart and bolt it in place, then tighten the whole cart.
Step 3: Fit the side shelves, handles and any side burner.
Step 4: Check the burners sit correctly over the gas valve outlets, then fit the flame tamers and cooking grates.
Step 5: Connect the hose and regulator to the gas cylinder and the grill, using a regulator suited to your gas type.
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.
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.
