Fire Mountain Sierra 6 Burner Stainless Steel Gas BBQ

Yes. The Sierra range has been designed with simplicity in mind, making it an excellent choice if you're buying your first gas BBQ.

Gas cooking means there's no need to wait for charcoal to reach temperature. Simply ignite the burners, allow the BBQ to preheat and you're ready to cook. Clearly marked controls also make it straightforward to adjust the heat while you're cooking.

The best size depends on how many people you normally cook for and how much cooking space you want.

• Sierra 2 Burner: Ideal for 1–3 people and smaller gardens, patios and outdoor spaces.
• Sierra 3 Burner: A great choice if you need a little more cooking space for family meals and entertaining.
• Sierra 4 Burner: Ideal for 3–6 people, with plenty of room for family meals and weekend gatherings.
• Sierra 6 Burner: The largest Sierra model, designed for bigger families, entertaining and anyone who wants plenty of cooking space.

Choosing a larger BBQ doesn't just mean cooking more food. Multiple burners also give you greater control over different areas of the cooking surface.

The main difference is the amount of cooking space and the number of independent heat zones available.

More burners allow you to create different temperature zones across the BBQ. For example, you could have one area on a higher heat for steaks while keeping another area at a lower temperature for vegetables or food that needs longer cooking.

The Sierra range therefore gives you a choice between a compact BBQ for everyday meals and a larger BBQ for entertaining.

Each Sierra burner produces 2.4kW of heat.

That gives the range a total burner output of:

• 2 Burner: 4.8kW
• 3 Burner: 7.2kW
• 4 Burner: 9.6kW
• 6 Burner: 14.4kW

The multiple-burner design provides consistent heat and allows you to control different cooking zones independently.

Yes. Sierra BBQs use premium cast-iron cooking grates, designed to retain and distribute heat effectively.

Cast iron is particularly useful for achieving a good sear and those classic BBQ grill marks on steaks, burgers, chicken and vegetables. It also holds heat well, helping maintain consistent cooking temperatures.

Yes. One of the biggest advantages of a multi-burner gas BBQ is the ability to create different heat zones.

You can turn individual burners up or down depending on what you're cooking. This is particularly useful when you're preparing several different foods at once.

For example, you could use high heat for burgers or steaks while using a lower-temperature area for vegetables, chicken or food that needs more gentle cooking.

Absolutely. A gas BBQ is much more versatile than many people realise.

As well as the usual burgers, sausages and steaks, you can use your Sierra to cook chicken, kebabs, fish, vegetables, corn, halloumi and much more.

You can also expand the cooking options of your Sierra with compatible cast-iron griddles. Fire Mountain offers dedicated griddles for the Sierra 2, 3, 4 and 6 burner models, providing a solid cooking surface that's particularly useful for foods such as smash burgers, bacon, eggs, fish and vegetables.

Yes. Fire Mountain offers purpose-built Sierra cast-iron griddles designed to fit specific Sierra models.

A griddle gives you an alternative cooking surface and is particularly useful for foods that could otherwise fall through the cooking grates or benefit from direct contact with a solid surface.

Always make sure you purchase the griddle designed for your specific Sierra model.

Sierra BBQs have been designed with straightforward maintenance in mind.

Cleaning the cooking grates after use helps prevent food and grease from building up, while regularly checking and cleaning the grease management areas helps keep your BBQ working efficiently.

For the best results, allow the BBQ to cool before carrying out a more thorough clean and follow the care instructions supplied with your particular model.

Sierra BBQs are designed with durable, weather-ready construction suitable for outdoor use. However, the UK's rain, frost and changing weather conditions can be hard on any outdoor appliance.

We strongly recommend using a suitable BBQ cover when your Sierra isn't being used. A cover helps protect the BBQ from rain, dirt and general exposure, helping it stay looking its best and extending its usable life.

If possible, storing your BBQ in a sheltered area during periods of particularly poor weather is also beneficial.

Yes. Gas BBQs can produce excellent BBQ flavour, particularly when cooking at high temperatures to create a good sear.

While charcoal produces a more pronounced smoky flavour, gas offers other advantages including faster start-up, easier temperature control and greater convenience.

For anyone who wants the traditional BBQ experience without the time and mess associated with lighting charcoal, a Sierra gas BBQ offers an excellent balance of flavour and convenience.

Generally, yes. One of the biggest advantages of gas is convenience.

With a gas BBQ, you can ignite the burners and begin preheating without having to light charcoal and wait for it to reach cooking temperature.

This makes the Sierra particularly convenient for spontaneous midweek BBQs as well as larger weekend gatherings.

The Sierra range has been designed with outdoor use in mind, including durable finishes and construction intended to cope with the changeable UK climate.

That said, no BBQ should simply be left exposed to the elements indefinitely. Using a quality cover and carrying out regular cleaning and maintenance will help protect your investment through the British summer and beyond.

For smaller gardens, patios and outdoor spaces, the Sierra 2 Burner is the most compact option in the range.

Its cooking area measures 40 x 42cm and it is designed for 1–3 people, making it a practical choice for couples, smaller families and anyone who doesn't need a large cooking surface.

For a typical family, the Sierra 3 Burner or 4 Burner are excellent choices.

The 3 Burner provides additional cooking space compared with the 2 Burner, while the 4 Burner offers a 60 x 42cm cooking area and is rated for 3–6 people.

If you regularly have friends and family over, choosing the 4 Burner gives you additional room to cook multiple foods at the same time.

If you regularly host larger gatherings, the Sierra 6 Burner is the largest option in the collection and gives you the most cooking space and burner power.

The additional burners allow you to create multiple cooking zones, making it easier to cook different foods at the same time when you're feeding a crowd.

The Sierra range has been designed to offer an accessible entry point into gas BBQ cooking without compromising on the features that matter most.

You get straightforward gas cooking, multiple burner options, cast-iron cooking grates, practical cooking space and a durable stainless-steel finish.

For someone buying their first gas BBQ or looking for an affordable upgrade, Sierra offers a simple way to get started with outdoor cooking.

Sierra BBQs are gas-powered, so you'll need a compatible gas bottle and regulator setup.

Before connecting your BBQ, always check the product manual and the specifications for your individual Sierra model to make sure you are using the correct gas supply, regulator and connection.

If you're unsure, contact the Fire Mountain support team before using the BBQ.

A little regular maintenance can make a big difference to the life of your BBQ.

We recommend:

• Cleaning the cooking grates regularly.
• Removing excess grease and food debris.
• Checking the grease management system.
• Keeping the BBQ covered when not in use.
• Checking burners and connections periodically.
• Following the cleaning and maintenance instructions supplied with your BBQ.
• Storing the BBQ somewhere sheltered where practical, particularly during prolonged periods of poor winter weather.

Looking after your Sierra properly will help keep it performing at its best for many BBQ seasons.

If you want a BBQ that's simple to use, easy to control and versatile enough for everyday outdoor cooking, the Sierra range is an excellent place to start.

With four sizes available, you can choose the cooking capacity that suits you—from the compact 2 Burner for smaller households through to the spacious 6 Burner for larger families and entertaining.

Whether you're cooking your first burgers, preparing a family meal or hosting friends in the garden, Sierra gives you the convenience of gas cooking without making outdoor cooking complicated.
