Step by step

What to do immediately after your Flamesa delivery arrives

Follow this sequence before commissioning the outdoor pellet heater. Keep the manual for the relevant model available at all times and use the videos as supplementary visual guidance.

Important The manual supplied for the specific Flamesa model always takes precedence during assembly, positioning and initial commissioning.

Review the model manual

Locate the manual for the relevant model and keep it available throughout the process. Use the videos as additional support, but always follow the manual.

Unpack all components

Carefully remove all components from the packaging and arrange them clearly. Use the manual to verify which components belong to the model supplied.

Assemble according to the manual

Assemble the outdoor pellet heater step by step in accordance with the model manual. Do not fit components based on assumptions or skip any steps.

Position the unit safely

Place the outdoor pellet heater on a level, stable and heat-resistant surface, with sufficient clearance and effective ventilation on all sides.

Complete the initial start-up

Use dry 6 mm pellets, do not overfill the heater and review the operating instructions in the manual once more before ignition.

Pre-use check

Before every use

Check these points before filling and igniting the Flamesa unit.

Glass positioned correctly Check that the glass is straight, secure and seated in its intended position.
Air openings clear Remove ash, dirt and pellet residue that could block the airflow.
Certified 6 mm pellets Use dry DINplus- or ENplus A1-certified wood pellets with a diameter of 6 mm.
Stable and level Place the heater on a level, solid and heat-resistant surface.
Sufficient clearance Always observe the minimum clearances stated in the manual for your specific heater. Allow more space where required by the model manual, canopy or surrounding materials.

Ignition

How to light your Flamesa correctly

Only use the ignition method specified for your model and keep the model manual close at hand.

Method 1

Lighting with a gas torch

Fill the heater as instructed in the manual. Insert the gas torch only through the designated ignition opening and direct the flame at the lower pellets until they have caught properly. Then withdraw the torch slowly from the opening.

Method 2

Lighting with a firelighter

Only do this when the heater is completely cold. Carefully lift the glass, place one firelighter in the combustion chamber and light it there. Immediately refit the glass correctly as described in the manual for your model.

Never use firelighter cubes, petrol, methylated spirits, bioethanol or other liquid accelerants. Keep your face, hands, clothing and flammable materials away from the flame.

Maintenance

After every use

Do not begin until the fire is fully extinguished and the entire heater has cooled completely.

Allow to cool completely Do not touch the glass, combustion chamber or metal components until everything is completely cold.
Remove ash and pellet residue Remove cooled residue from the combustion chamber and around the air openings.
Clean the glass safely Only clean the glass once it has cooled completely and visible soot or dirt deposits are present. Remove the glass from the heater and spray it with our stove cleaner. Then scrub the glass thoroughly using the brush from the Flamesa® Pellet Stove Cleaning Kit Pro and rinse it thoroughly afterwards. The glass does not need to be cleaned after every use.
Check the air supply Check that ash, dust and pellet residue are not blocking any openings or passages. Carefully loosen any buildup with the supplied cleaning rod.
Store dry with a protective cover Allow the heater to cool and dry completely. Then store it in a dry place with a suitable Flamesa protective cover . Never place the cover over a warm heater.

Always follow the manual for your model The correct filling quantity, assembly and operation may differ by Flamesa model. The manual for your specific model therefore always takes precedence.

Use & common mistakes

Prevent and solve problems with lighting, smoke, pellets or the flame.

What should I check before lighting my Flamesa?

Check that the heater is fully and securely assembled, standing level and stable, and free from damage. Also check that the glass is positioned correctly, the air openings are clear and no old ash or pellet residue remains in the combustion chamber.

Do not use the heater if the glass is damaged, components are loose or openings are blocked.

Which pellets are suitable for my Flamesa?

Use only dry wood pellets with a diameter of 6 mm. Good pellets contain little dust, are firm and do not crumble easily.

Damp or poor-quality pellets can cause smoke, an unstable flame, black deposits and a blocked pellet feed. We always recommend DINplus- or ENplus A1-certified pellets for clean and efficient combustion.

Do not use logs, charcoal, briquettes, bioethanol or any other fuel.

How many pellets should I put in the heater?

The correct quantity differs by model. Fill the reservoir according to the manual for your Flamesa and never exceed the indicated level.

More pellets do not automatically increase the burn time. Overfilling can reduce airflow, create extra smoke, cause poor combustion or prevent the pellets from feeding correctly.

How do I light my Flamesa correctly?

Use the lighting method described in the manual for your model. Make sure the pellets ignite properly and allow the heater enough time to establish a stable burn.

If the fire is lit too briefly or inadequately, the pellets may smoulder. This often causes additional smoke and a weak flame.

Is an odour during the first use normal?

During the first few hours of burning, a slight odour may occur as the heat-resistant coating and manufacturing residues warm up. This normally decreases after several uses.

Provide extra ventilation during the first use. Stop using the heater if you notice thick smoke, deformation, damage or a persistent strong chemical smell.

Why does my pellet heater smoke while lighting?

A small amount of smoke during initial ignition can occur. Persistent or thick smoke is usually caused by incomplete combustion.

After the heater has completely cooled, check:

whether the pellets are completely dry;
whether the pellets were ignited properly;
whether the combustion chamber is clean;
whether the air openings are clear;
whether wind is disturbing the combustion.

Why is the flame too low or unstable?

A low, weak or unstable flame usually means the combustion is not receiving enough air, heat or an even pellet supply.

Possible causes include:

The heater is positioned in an unsuitable location, for example too sheltered, too close to a wall or directly in strong wind.
Rain, strong wind, gusts or other weather conditions are disturbing the natural airflow.
Clinker has formed: hard, fused residue in the combustion chamber is blocking the air openings.
The pellets are damp, too dusty, poor quality or unsuitable for the heater.
The combustion chamber, pellet feed or air openings are not properly clean.
The combustion is receiving too little air because of a blockage, incorrect positioning or insufficient clearance.
The pellets were not ignited sufficiently or the heater has not had enough time to build a stable flame.

Allow the heater to burn out and cool completely. Then remove ash, pellet residue and any hard clinker. Check that all air openings and passages are completely clear and position the heater in an open, stable and suitable location as specified in the manual. Try again using dry 6 mm DINplus- or ENplus A1-certified pellets .

Does the flame remain consistently too low after these checks? Stop using the heater and contact our customer service. Include a clear video of the flame and photos of the combustion chamber, pellets and installation location.

Why does the flame become very high?

A high or strongly fluctuating flame can be caused by too many pellets, strong wind or excessive airflow. Do not add extra pellets and only adjust an official air control if your model has one.

Does the flame remain uncontrollably high? Keep your distance and allow the heater to burn out according to the manual.

The pellets are not feeding properly. What should I do?

Pellets may become stuck if they are damp, swollen or very dusty. Old residue can also block the feed.

Allow the heater to burn out and cool completely. Then clean the pellet feed and use fresh, dry pellets.

Never insert tools or your hands into the pellet feed while the heater is burning or still hot.

Can I add pellets while the heater is burning?

This differs by model. Only refill while the heater is burning if the manual for your Flamesa explicitly allows it and describes a safe procedure.

Never overfill and keep your face, hands and clothing away from the opening and hot components.

Maintenance & safe use

Correct positioning, cleaning and protection for reliable long-term use.

How much clearance should I keep around my Flamesa?

Always maintain the minimum clearance around the pellet heater specified in the manual for your Flamesa model.

The required distance may vary by model and situation. Always follow the clearances and positioning instructions in the corresponding manual.

Make sure heat, smoke and combustion gases can always disperse freely.

Can I use my Flamesa under a veranda or canopy?

Yes, provided the area is sufficiently open and permanently ventilated. The heater is intended for outdoor use and must not be used in a fully enclosed conservatory, garden room, shed or indoor space.

Always maintain the minimum clearance above and around the pellet heater specified in the manual for your Flamesa model. The required distance may vary by model and situation.

Can I use the heater in rain or strong wind?

Do not use the pellet heater in rain, snow or severe wind gusts. Water on hot glass can cause thermal stress, while strong wind can disrupt the flame and airflow.

Allow a wet heater to dry completely and inspect it for damage before using it again.

Can I move a mobile Flamesa while it is burning?

No. Only move the heater once the fire is completely out and all components have fully cooled.

The wheels are intended to make a cold heater easier to move, not to move it while burning or cooling down.

Why does the glass turn black?

Black deposits usually indicate incomplete combustion. Possible causes include damp pellets, insufficient air, dirty air openings, too many pellets or poor ignition.

Do not only clean the glass; also check the combustion chamber, pellets and air supply. Otherwise, the deposits will quickly return.

How often should I remove ash and pellet residue?

Allow the heater to cool completely after use and remove remaining ash and pellet residue before it accumulates.

Before every new use, check that the combustion chamber and air openings are clean and completely clear. Even a thin layer of ash can affect the airflow.

How do I clean the glass safely?

Only clean the glass once it has completely cooled. Use a soft cloth and a suitable stove-glass cleaner.

Do not use steel wool, a hard scouring pad, aggressive degreaser or cold water on warm glass.

How do I clean the metal components?

Use a soft, slightly damp cloth and a mild cleaning product. Dry the components thoroughly afterwards to reduce water marks and corrosion.

Avoid abrasive or caustic products. If in doubt, test the cleaner first on a small, inconspicuous area.

How should I store my Flamesa and pellets?

Allow the heater to cool completely, clean it and store it in a dry place protected from prolonged rain and moisture.

Always use a correctly fitting protective cover, but never place it over a warm or damp heater. Store pellets dry and sealed so they cannot swell or crumble.

When should I stop using the heater and contact customer service?

Stop using the heater if you notice:

cracked or broken glass;
loose or missing components;
an unstable or deformed frame;
persistent thick smoke;
a blocked pellet feed;
a repeatedly uncontrolled flame.

When contacting us, include your order number and model name, together with clear photos of the complete heater and the problem.
