Gas BBQs offer convenient lighting, adjustable heat and no charcoal ash to remove. They suit quick meals and cooking with different heat zones. Charcoal offers a different cooking experience and flavour. Compare our gas BBQ range with how you like to cook.
Yes. Burner controls make heat adjustments straightforward, and you can start with familiar foods. Read the instructions first, learn the lighting procedure and practise using a cooler cooking area alongside direct heat.
Consider the cooking area, your usual guest numbers and whether you want to cook several dishes together. Also measure your outdoor space, allowing for the safety clearances and open side shelves. A compact Sierra 2 Burner BBQ is one option for smaller cooks.
Sierra offers straightforward stainless steel gas BBQs. Cascade adds options with side burners and a dual fuel model. Olympus is our premium gas range. Compare individual specifications and our gas BBQ buying guide before choosing.
Yes, that's correct. For example, the Cascade 4 Burner (3+1) has three main burners and one side burner. The Olympus 5 Burner (3+2) has three main burners and two side burners.
A conventional side burner provides heat for suitable pans, such as when preparing sauces. A sear burner is designed for intense direct heat. They are not interchangeable: check the model’s equipment and instructions before choosing cookware or a cooking method.
Assembly requirements vary by model. Check the product page and gas BBQ instruction manual before delivery. Plan enough space and help for the larger components, and do not connect gas or use the BBQ until assembly is complete.
We recommend propane for Fire Mountain gas BBQs. Check your model’s data label and manual for the required operating pressure and permitted fuel. Do not change fuel type or fittings without confirmed compatibility.
Use a propane bottle with the correct connection and sufficient capacity for your BBQ, within the restrictions in its manual. The gas supplier can advise on available bottles. Bottle colour or physical size alone does not confirm compatibility.
Gas bottles are not supplied with any of our gas BBQs. A regulator and hose is included with the Olympus range, but need to be purchased separately for all other models.
Match the regulator pressure, cylinder connection and hose specification to your model. Our 27mm propane gas regulator has a model-specific compatibility description, so do not assume its supplied hose fits every BBQ. If unsure, contact Fire Mountain with your product details before buying.
Connect outdoors with the gas supply and burner controls off. Follow the instructions for your BBQ, hose, regulator and cylinder, secure the specified connections and check that the hose is clear of hot parts. Complete the manual’s leak test before lighting.
Do not force the connection or use an improvised adaptor. Ask your gas supplier to confirm the cylinder valve and suitable regulator, then check the regulator against your BBQ’s required pressure and hose specification.
Follow your BBQ manual, component instructions and expiry markings, using the shortest applicable interval. Current Sierra and Olympus manuals specify hose replacement every two years. Replace damaged, cracked, worn or leaking components immediately. The hose interval does not automatically set the regulator’s lifespan.
Bottle size, burner output, heat settings and cooking time determine gas use, so there is no single reliable number of cooks per bottle. A compatible spare can be useful, provided it is stored upright outdoors in a suitable ventilated place away from ignition sources.
Remove packaging and protective films, complete assembly and follow the first-use cleaning and heating instructions. Check the gas components and connections before lighting. The initial heating procedure varies by model, so use your gas BBQ instruction manual.
With the BBQ cold and burner controls off, follow your manual’s leak-testing procedure using suitable leak-detection fluid or soapy water. Growing bubbles indicate a leak. Shut off the gas and resolve the problem before use. Never test with a flame.
Stop using it. Shut off the cylinder only if safely accessible, keep people away and avoid flames or electrical switches nearby. Move to a safe distance and contact your gas supplier’s emergency service. Call 999 if there is fire or immediate danger.
Use a firm, level, non-combustible surface outdoors with the clearances in your manual. Keep the BBQ away from fences, vegetation, furniture and busy routes. Our BBQ safety FAQs cover positioning and preparation in more detail.
Follow the cylinder location specified for your model. Current Sierra and Olympus instructions require the cylinder outside the appliance body. Do not assume a cabinet is suitable simply because a bottle fits. Keep the cylinder upright and the shut-off accessible.
No. Fire Mountain gas BBQs are for outdoor use in a suitable open area. Never use one inside a home, garage, shed or tent, even with doors open. We advise against balcony use because of fire risks to the building and neighbouring properties.
Do not use it beneath a parasol, ordinary fabric gazebo or canopy. Follow your model’s restrictions on overhead coverings, ventilation and clearances. Open sides alone do not make a shelter suitable for cooking.
Avoid strong winds, storms and heavy rain. Wind can disturb the flames and affect heat control. If weather makes cooking unsafe, stop and shut down as instructed. Never move a lit BBQ into a garage or beneath an unsuitable shelter.
Open the cooking lid, check the controls are off and follow your model’s gas and ignition sequence. Light each burner as instructed and confirm it is burning. If ignition fails, shut off the controls and gas, then wait the prescribed time before retrying.
Yes. Open the main cooking lid before lighting to avoid unburnt gas collecting beneath it. Open a side burner’s cover before using that burner. Follow the separate ignition procedure if your model has a sear burner.
Many gas BBQs need around 10 to 15 minutes of preheating, but weather, settings and cooking surfaces affect readiness. Follow your manual and monitor the temperature. Never exceed the permitted temperature or use an all-burners-on-high method against the instructions.
Adjust the burner knobs and allow time for the cooking surface to respond. Use the thermometer as a guide and create different heat zones where the model permits. Turning every burner to maximum is not necessary for most meals.
Follow your model’s manual. Current Sierra and Olympus instructions limit closed-lid cooking to 250°C and prohibit using all burners on high. Do not apply high-temperature kamado or pizza oven instructions to a gas BBQ.
Direct heat cooks above a lit burner. For indirect cooking, use a permitted burner arrangement that heats food without a flame directly beneath it. Keep monitoring the food and cooker. See our BBQ cooking FAQs for more cooking techniques.
No. It indicates temperature near its position in the cooking chamber. Grill-level heat can differ, and neither reading confirms the centre of your food is cooked. Use a clean food thermometer to check food safely.
Gas BBQs can cook meat, fish, vegetables and many other dishes using the appropriate method and compatible accessories. A suitable BBQ griddle can expand your options. Check fit, positioning and temperature limits before using an accessory.
Yes, if you cook it thoroughly and handle it hygienically. Keep raw chicken and its utensils separate from cooked food, allow enough cooking time and check the centre with a food thermometer. Do not rely on browning alone.
Foods requiring thorough cooking, such as chicken, burgers and sausages, should reach a core temperature of 70°C for two minutes or a recognised equivalent combination. Follow packaging instructions and use a clean food thermometer. Our BBQ cooking FAQs explain checking doneness.
Only when the food’s packaging gives a suitable cook-from-frozen method for barbecuing. Otherwise defrost safely before cooking. Frozen centres can remain undercooked while the outside browns, so check the food thoroughly rather than judging by appearance.
A cold or dirty surface can cause sticking. Preheat within your manual’s limits, clean the cooking surface and use a small amount of suitable oil as appropriate. Allow food to develop a cooked surface before trying to turn it.
The direct heat may be too intense for the food’s thickness. Reduce the heat or use a suitable indirect cooking area. Check the centre with a food thermometer. Keep sugary sauces for later in the cook to reduce scorching.
A warming rack is useful for short periods, but does not guarantee safe hot holding. Serve food promptly, keep raw food and juices away from it and check the rack’s permitted use. Never assume food is safe because the BBQ lid is warm.
Gas and charcoal offer different flavour profiles, but grilling still adds flavour on gas. Marinades and rubs provide more options. Only use a smoker box if your manual permits the set-up. Never put charcoal or loose wood over gas burners.
Shut off the controls and gas before checking. Once cold, check the fuel supply and permitted ignition checks in your manual. Allow unburnt gas to disperse before retrying. Never keep operating the ignition while gas flows. Contact Fire Mountain if the fault persists.
Possible causes include low fuel, unsuitable gas components, windy conditions or blocked burner ports. Check the manual’s troubleshooting steps once the BBQ is off and cold. Do not adjust jets or bypass safety devices to increase the heat.
Only follow a reset procedure provided for your specific regulator or BBQ. Not every regulator has the same safety mechanism. Turn the BBQ off and ask your gas supplier or Fire Mountain for help if the instructions do not identify an approved procedure.
Persistent abnormal flames may indicate a burner, airflow or gas supply problem. Stop using the BBQ and inspect only the items your manual permits once cold. Do not modify air settings or gas jets. Contact Fire Mountain if the problem remains.
Turn off the burner controls and gas supply. Open the lid and allow gas to disperse for the waiting time specified in your manual before relighting. If it happens repeatedly, stop cooking and investigate the fault before further use.
Burner position, wind, grill loading and food placement can create different heat zones. If uneven heating is new or severe, inspect for permitted cleaning issues or damaged heat plates once cold. Do not assume a burner fault can be fixed by increasing every control.
Fat dripping onto hot surfaces, excess oil and grease build-up are common causes. Keep grease collection areas clean, trim excess fat and move food away from a small flare-up only if safe. Our gas BBQ cleaning guide explains routine maintenance.
Keep people away and do not move the BBQ. Shut off the gas only if safely accessible and keep the lid closed for a contained grease fire. Never use water. If fire spreads, involves the cylinder or cannot be controlled safely, move away and call 999.
Check the cooking surface and grease collection areas before every cook. Clean regularly after use and deep clean as needed for your usage. Always follow the model’s shutdown and cooling instructions. Use our gas BBQ cleaning guide for a practical maintenance routine.
Once cool and with the fuel isolated, remove only components allowed by the manual. Use the cleaning method specified for each material, rinse where appropriate and dry thoroughly before reassembly. Never reinstall damaged heat plates or leave cleaning residue on cooking surfaces.
Turn off and isolate the gas, then wait until the BBQ is cold. Follow the manual before removing burners or clearing ports. Avoid introducing water or enlarging openings. Damaged burners or uncertain gas connections need advice from a competent professional.
Follow the surface-specific instructions, particularly where cast iron has a coating. Clean without damaging the finish, dry thoroughly and apply suitable cooking oil where instructed. Do not leave cast iron soaking or store it wet.
Yes. Stainless steel still needs care, especially where moisture, grease or salt accumulates. Clean and dry it according to your manual and protect it between uses. Avoid abrasive tools or chemicals that could damage the finish.
No. Current Fire Mountain guidance states that BBQ parts are not dishwasher safe. Hand-clean each component using the method in your manual, then dry it properly before reassembly or storage.
Avoid pressure washing or hosing down the inside. Water can enter burners, ignition components and areas that are difficult to dry. Use controlled cleaning methods suited to each surface and follow your model’s care instructions.
Check for wear, loose bristles and damaged handles before use. Replace a worn brush and inspect the cooking surface for loose bristles after cleaning. Choose a tool suitable for the grill finish. Browse our BBQ accessories and check your manual’s recommendations.
Yes, with appropriate protection and maintenance. Keep it clean and dry and use a correctly fitting cover once completely cold. Inspect it before use, including after long periods outdoors. A cover does not replace care of the gas components.
Turn off and disconnect the gas as instructed, clean away grease and food residue, and dry the BBQ thoroughly. Store or cover it only when cold. Inspect the hose, regulator, burners and fixings before returning it to use.
Store propane cylinders upright outdoors in a well-ventilated place, away from heat, ignition sources, drains and building entrances. Keep the valve closed. Do not store them in a home, garage, shed or cellar. Treat empty bottles with the same care.
Turn off the burners and gas supply after every use, following the shutdown sequence in your manual. Disconnect the cylinder when the instructions require it, particularly for storage, using the regulator procedure outdoors and away from ignition sources.
Do not use it if corrosion or damage affects its stability, gas system or safe operation. Cosmetic marks and structural damage need different treatment. Contact Fire Mountain with photographs if you are unsure, and replace unsafe components before cooking.
Check our BBQ spare parts for available components. Parts must match your specific model and product code. If you cannot identify the correct item, contact Fire Mountain with your BBQ details before ordering. Do not adapt an incompatible gas component.
Visit our user manuals page and choose the document matching your product code. It includes current Sierra, Cascade and Olympus manuals, plus archived ranges. Ask our team if your model is missing or the document does not match.
Use our contact page and provide your model name, product code, order details and photographs where helpful. Our team can advise on product use and suitable parts. Stop using the BBQ while any unresolved fault could affect safety.
