Fire Mountain Cascade 4 Burner Gas BBQ (3+1)

Cascade BBQs are ideal for regular BBQ users, families and keen home cooks who want more from their BBQ.

If you've outgrown a smaller entry-level model, regularly entertain friends and family, or simply want more control over your cooking, Cascade provides a natural step up from the Sierra range.

The collection is designed to handle everything from quick midweek meals to longer weekend cooks, giving you the flexibility to experiment with different cooking techniques.

The simplest way to think about the two ranges is:

Sierra is designed to make BBQ cooking easy. Cascade is designed to give you more ways to cook.

Cascade offers more power, greater cooking capacity and additional flexibility, while retaining the straightforward convenience of gas cooking.

The Cascade collection is particularly suited to people who are becoming more confident with BBQ cooking and want to experiment with techniques such as indirect cooking, reverse searing, roasting and slow cooking.

The Cascade range currently includes four options:

• Cascade 4 Burner (3+1): A compact multi-burner BBQ with three main burners plus a side burner.
• Cascade 5 Burner (4+1): Four main burners plus a side burner, offering additional cooking space and flexibility.
• Cascade 7 Burner (6+1): Six main burners plus a side burner, designed for larger families and entertaining.
• Cascade Dual Fuel: Combines gas and charcoal cooking for maximum flexibility.

This means there's a Cascade for everything from regular family meals to larger garden gatherings.

The numbers refer to the BBQ's burners.

For example, the Cascade 4 Burner (3+1) has three main cooking burners plus one additional side burner.

The Cascade 5 Burner (4+1) has four main burners plus a side burner, while the Cascade 7 Burner (6+1) has six main burners plus a side burner.

The side burner gives you an additional cooking area away from the main grill, which can be particularly useful for sauces, vegetables, side dishes and other foods you want to prepare alongside your main BBQ.

The side burner adds another useful cooking zone to your BBQ.

It's ideal for heating sauces, cooking side dishes, simmering vegetables or preparing foods that you'd normally make on your kitchen hob.

This means you can prepare more of your meal outdoors rather than constantly going back and forth between the BBQ and the kitchen.

Cascade BBQs are designed to provide a step up in cooking power compared with the Sierra range.

The main burners produce 2.8kW each, while total burner output varies by model:

• Cascade 4 Burner (3+1): 10.9kW total
• Cascade 5 Burner (4+1): 13.7kW total
• Cascade 7 Burner (6+1): 19.3kW total

Cooking space varies depending on the model:

• Cascade 4 Burner: 51.5 x 37.5cm
• Cascade 5 Burner: 61.5 x 37.5cm
• Cascade 7 Burner: 81.5 x 37.5cm

The larger models are particularly useful when you're cooking different foods simultaneously or preparing food for a larger group.

The right model depends on how often you entertain and how much food you normally cook at once.

The Cascade 4 Burner is a good choice for regular family meals and smaller gatherings.

The Cascade 5 Burner is rated as ideal for 3–6 people, making it a versatile option for families and those who regularly have friends over.

The Cascade 7 Burner is designed for 6+ people, providing substantially more cooking space for larger gatherings and entertaining.

Yes. This is one of the key advantages of having multiple independent burners.

You can adjust individual burners to create different temperature zones across the cooking surface.

For example, you could have one area on high heat for searing steaks, another on medium heat for burgers and vegetables, and a cooler area for food that needs to cook more slowly.

This makes Cascade BBQs particularly versatile for more advanced cooking techniques.

Yes. The multiple-burner configuration makes Cascade BBQs well suited to indirect cooking.

Instead of placing food directly above an active burner, you can turn off the burner underneath the food while keeping the surrounding burners on.

This creates an area of indirect heat that's useful for larger cuts of meat, whole chickens, roasting and slower cooking.

Yes. Cascade BBQs are designed to give you the temperature control needed to experiment with techniques such as reverse searing.

You can start the steak gently using indirect heat before finishing it over a much hotter part of the grill to develop a deeply browned exterior.

It's a great example of how a multi-burner gas BBQ can be used for more than traditional burgers and sausages.

Absolutely. With multiple burners and different cooking zones, Cascade BBQs can be used for roasting as well as grilling.

Indirect heat is particularly useful for foods such as whole chickens, larger joints of meat and tray-roasted vegetables.

The enclosed BBQ environment can also help retain heat while your food cooks.

Yes. Fire Mountain offers a Cascade BBQ Griddle, specifically designed for the Cascade Gas BBQ range.

A cast-iron griddle provides a solid cooking surface and adds another level of versatility to your BBQ. It's particularly useful for foods such as smash burgers, bacon, eggs, fish, vegetables and other ingredients that benefit from a flat cooking surface.

The Cascade griddle measures 200 x 300mm and is designed to make better use of your available cooking space.

Yes. The Cascade Dual Fuel BBQ gives you the flexibility to cook using either gas or charcoal.

This makes it an excellent option if you like the convenience and temperature control of gas but don't want to give up the traditional flavour and cooking experience associated with charcoal.

It's effectively two cooking methods in one BBQ, allowing you to choose how you want to cook depending on the food, occasion or amount of time you have available.

A standard gas BBQ is ideal if convenience and precise temperature control are your priorities.

A Dual Fuel BBQ gives you another option: charcoal cooking.

Gas is ideal for quick family meals when you want to get cooking with minimal preparation, while charcoal can be used when you have more time and want that traditional BBQ experience and smoky flavour.

The Cascade Dual Fuel therefore offers greater flexibility than a conventional gas-only BBQ.

Gas BBQs can produce excellent searing and BBQ flavour, but they won't naturally produce the same level of smoky flavour as cooking directly over charcoal or wood.

If smoky flavour is particularly important to you, the Cascade Dual Fuel is worth considering because it gives you the option of cooking over charcoal.

For everyday cooking, however, gas offers significant advantages in speed, temperature control and convenience.

Yes, although Cascade is aimed more towards regular BBQ users and people who want to develop their cooking skills.

The gas controls remain straightforward to use, so you don't need to be an experienced BBQ chef to get started.

At the same time, the additional burners and cooking zones give you plenty of room to develop your skills as you become more confident.

Absolutely. The larger cooking surfaces and multiple burners make Cascade BBQs particularly well suited to entertaining.

The 5 Burner is a strong all-round option for family gatherings and groups of around 3–6 people, while the 7 Burner is designed for groups of 6 or more.

Multiple burners also mean you can cook different foods at different temperatures rather than trying to fit everything onto one hot zone.

Yes. This is one of the areas where Cascade really comes into its own.

You can use the main cooking area for meat, fish or vegetables, create an indirect cooking zone for slower-cooked food and use the side burner for sauces or side dishes.

With a griddle added, you can expand the range of foods you can cook outdoors even further.

Like any BBQ, regular cleaning is important for maintaining performance and appearance.

We recommend cleaning the cooking surfaces regularly, removing food debris and excess grease, and checking the grease management areas.

The Cascade's powder-coated exterior is also designed to be durable and practical for regular outdoor use.

Always allow the BBQ to cool sufficiently before carrying out a more thorough clean and follow the care instructions supplied with your particular model.

Cascade BBQs are designed for outdoor use and feature a durable black powder-coated finish designed to withstand everyday outdoor conditions.

However, the UK's weather can be unpredictable, and prolonged exposure to rain, frost and dirt can affect any outdoor BBQ.

For this reason, we recommend using a purpose-made Cascade BBQ cover when your BBQ isn't being used.

Fire Mountain offers custom-fit covers for the Cascade 4, 5 and 7 Burner models.

There are several accessories available to help you get more from your Cascade BBQ, including:

• Cascade BBQ Griddle
• Model-specific BBQ covers
• BBQ cleaning equipment
• BBQ tools and accessories

A griddle is particularly worthwhile if you want to expand beyond traditional grilling and cook foods that benefit from a flat surface.

It really comes down to how you cook and how many people you normally feed.

Choose the Cascade 4 Burner if you want a capable multi-burner BBQ for regular family meals but don't need the largest cooking area.

Choose the Cascade 5 Burner if you want an excellent balance between cooking space, power and versatility. It's a particularly strong choice for families and regular entertaining.

Choose the Cascade 7 Burner if you regularly cook for 6+ people or simply want plenty of room to create multiple cooking zones.

Choose the Cascade Dual Fuel if you want the flexibility to switch between gas and charcoal and enjoy both convenience and traditional charcoal cooking.

Cascade is designed for people who want to take their outdoor cooking further.

You get more power and cooking capacity than the entry-level Sierra range, along with multiple burners for better temperature control, side burners on the 3+1, 4+1 and 6+1 models, and the option to explore techniques such as indirect cooking, roasting and reverse searing.

And if you choose the Dual Fuel model, you can switch between gas and charcoal depending on how you want to cook.

In short, Cascade is the sweet spot for BBQ enthusiasts who want more capability without the complexity or price of a professional-level BBQ.
