Gas grill GG421

Outdoor Gas Grill with 4 Burners and Side Burner

The Blaupunkt GG421 is a four-burner outdoor gas grill built for those who value a solid construction, a large grilling area and effortless operation. Equipped with 4 main burners rated at 4 kW each and a side burner rated at 2.8 kW, the grill delivers a combined output of 18.8 kW and a generous 69 x 45 cm grilling surface – enough to cook a meal for a large group all at once.

The GG421 stands out with LED knobs that signal each burner’s status by colour (blue = off, red = on), an enamelled firebox rated to 550°C, a high-performance stainless steel flame tamer that perfectly disperses heat throughout the cooking chamber, and two removable cast iron grates. The lid, cabinet doors and control panel are made of SUS430 stainless steel for long-lasting weather resistance.

The GG421 is the grill for those who want a reliable, straightforward outdoor cooking solution – with thoughtful features that make cooking easier and daily maintenance simple.

Why Choose the Blaupunkt GG421? – 7 Key Reasons

1. Four Independent Burners – High Output and Flexible Heat Zones

The GG421’s four main burners, each rated at 4 kW, deliver 16 kW of output across the main cooking surface. Independent control of each burner lets you set up multiple temperature zones simultaneously: intense heat for searing steaks, moderate heat for chicken, low heat for warming sides. The independent 2.8 kW side burner adds a separate cooking station without taking up grate space.

2. Backlit LED Knobs – Burner Status at a Glance

The GG421 features control knobs backlit by LED indicators that serve two purposes. First, they signal the status of each burner at a glance: when a burner is turned off, the knob glows blue; when it is turned on, it switches to red. This makes it immediately clear which burners are active without having to check for a flame. Second, the illuminated knobs add an elegant finishing touch, giving the grill a premium look both during the day and in the evening.

3. High-Performance Stainless Steel Flame Tamer – Perfect Heat Distribution

The GG421 is equipped with a high-performance stainless steel flame tamer designed to perfectly disperse heat throughout the entire cooking chamber. It distributes temperature evenly across the full width of the grate, eliminating cold spots and ensuring consistent cooking conditions. At the same time, it shields the burners from dripping fat and meat juices – the vaporisation of those drippings on the hot tamer adds a lightly smoky flavour to your food. The stainless steel construction is more durable than enamelled alternatives and does not warp under prolonged high-heat operation.

4. Two Removable Cast Iron Grates – Maillard Effect and Easy Cleaning

Cast iron has exceptional thermal properties: it accumulates heat and maintains a stable, high surface temperature even after placing cold ingredients on it. This produces the Maillard effect – deep caramelisation of the outer layer of food and characteristic grill marks. The GG421 comes with two separate, removable cast iron grates. Removing them makes it easy to clean each grate individually and, if necessary, replace a single grate without purchasing the entire set.

5. Enamelled Firebox – Rated to 550°C

The GG421’s firebox interior is coated with high-temperature enamel rated to 550°C. This prevents corrosion, simplifies cleaning and ensures the longevity of the appliance. The enamelled surface will not rust even after years of intensive use.

6. SUS430 Stainless Steel – Durable, Easy-Clean Body

The lid, control panel and lower cabinet doors are made of SUS430 stainless steel – highly resistant to corrosion, oxidation and heat. The body will not fade or rust and is far easier to clean than powder-coated steel.

7. Mobility and Ergonomics – 4 Wheels, 2 with Brakes

The GG421 (131 x 57 x 116 cm) rolls easily on 4 wheels, two of which have brakes for secure locking. The enclosed stainless steel lower cabinet holds the gas cylinder and keeps the area around the grill tidy.

How to Use the Blaupunkt GG421 – User Guide

Lighting and Pre-Heating

Before first use, assemble the grill following the instruction manual (estimated assembly time: 45–60 minutes). Connect the gas cylinder using the included regulator. Pre-heat by setting all burners to maximum, closing the lid and waiting 10–15 minutes until the thermometer reads 250–300°C. Knobs glowing red confirm the burners are on. Reduce burner output to create your desired heat zones.

Grilling on Cast Iron Grates

Before each use, lightly coat the cast iron grates with a high-smoke-point oil (e.g. rapeseed or grapeseed). Place meat on the hot grate and do not move it for the first 2–3 minutes to allow a crust and grill marks to form. Rotate 90° on the same side for a crosshatch effect. Cook poultry and fish at lower heat with the lid closed.

Side Burner – Cooking in Parallel

The 2.8 kW side burner is fully independent and can hold a pot or pan. Use it for sauces, soups, boiling beans or corn – all while grilling on the main surface, with no cross-temperature interference.

Assembly and First Start-Up – Step by Step

1. Unpack all parts and identify them according to the instruction manual.
2. Assemble the lower cabinet frame, fit the doors and attach the wheels (braked wheels at the front).
3. Place the grill body on the frame and attach the side shelf.
4. Install the burners, flame tamer and cast iron grates.
5. Connect the gas regulator to the cylinder (propane-butane LPG).
6. Check all connections for leaks using soapy water.
7. Carry out the first light-up and season the cast iron grates.

Maintenance and Cleaning – Blaupunkt GG421

Cast Iron Grates

After each use, while the grate is still warm, scrub food residue with a wire brush and rub with a thin coat of vegetable oil. Remove the grates to clean each one individually. Do not wash in a dishwasher – hand-wash only with warm water and minimal detergent.

Firebox and Flame Tamer

Clean the enamelled firebox after it has fully cooled, using a damp cloth or soft sponge. Remove the stainless steel flame tamer and wash separately in warm, soapy water. Regular cleaning prevents fat build-up and fire risk.

Stainless Steel Body

A damp cloth with a drop of washing-up liquid is sufficient for everyday care. Avoid abrasive pads and chlorine-based products. For stubborn marks, use a stainless steel cleaner applied in the direction of the grain.
