The HOME FLAME COLLECTION is characterized by its innovative and patented “Safe Stone-Fire” combustion chamber construction. The construction combined with optimal consumption enable an excellent price/performance ratio. In addition, all models meet safety requirements and can be put into operation without any problems without the need for maintenance by a chimney sweep. The products WALL FLAME and FLOOR FLAME are TÜV tested.

Use on parquet is considered harmless.

When starting up on carpets, make sure that the combustion chamber does not come into direct contact with the carpet. High-pile carpets are therefore unsuitable.

The construction of these FLAMES is only suitable for wall mounting.

This is possible if the safety instructions are followed.

The following flames can be used indoors and outdoors: Semi Flame, High Flame, Top Flame and the Uni Flame. Wall Flame I & II and the Corner Flame are only recommended for indoor use.

There is no safety guarantee for modifications.

Any kind of decoration must be made of fireproof material. The combustion chamber itself must remain free of any objects.

Kilowatt is a unit for measuring the heating capacity and can therefore not be given in °C. The actual temperature depends heavily on external influences such as room size and air supply. Since it is an open fire, a pleasant warmth will develop.

They can get very hot. Avoid touching the glass panes during operation. When the flame goes out, the glass cools down quickly.

The underside of the combustion chamber reaches a temperature of approx. 80°C.

The stainless steel surface does not develop extreme temperatures. Nevertheless, you should avoid touching the surfaces in the immediate vicinity of the combustion chamber.

In principle, commercial bio-ethanol can be used. However, impure ethanol can lead to undesirable residues, severe soiling of the fuel stone and unpleasant odors. Bio-ethanol from RADIUS DESIGN (item no. 536 5 litres, 10 litres) corresponds to the following guidelines: bio-ethanol 96%, denatured, 1% MEK, contains Bitrex.

No, if the fuel stone is not used, the modified construction is no longer subject to our safety regulations. We therefore advise against any design changes.

In order to obtain a harmonious flame pattern, the fuel stone must be completely covered with bio-ethanol.

The small flames can easily be extinguished by quickly opening and closing the flaps. If necessary, the process can be repeated.

No. Please note the safety instructions.

The processed stainless steel V2A is rust-resistant. However, it is possible for mailboxes to rust in atmospheres containing iodine (coasts, industrial areas, busy roads and railway lines). In these cases, the specialist trade offers various stainless steel care products. We recommend cleaning the mailboxes regularly.

The mailbox can be mounted on house walls as well as on enclosures, provided the enclosure can hold the mailbox. Alternatively, we also offer the letterboxes as a standing version (excluded Letterman 3 and Letterman 6) or the parcel mailbox Letterman Standing ovation. The standing mailboxes can be anchored in the ground with the separately available ground anchor or with suitable dowels and bolts. Care should be taken to ensure that the surface is flat and stable. Smaller unevenness can be compensated for using suitable washers if necessary.

The material thickness is approx. 1 mm. However, this information can vary by a few micrometers depending on the model. Since the colored mailboxes are powder coated, the material thickness is slightly higher. The glass plate of the mailbox Letterman 3 is approx. 6 mm and the stainless steel housing is approx. 1 mm thick.

The stainless steel mailboxes and the matching posts are made of stainless steel. The colored mailboxes and posts are made of powder-coated steel. The porthole is made of mirror-polished stainless steel and glass.

In order to ensure optimal weather protection, the upper flap closes by itself.

It is possible to let the mailbox into the wall. Due to the functions of the closing flaps, it is not possible to let them in completely. The mailbox therefore protrudes 3-4 cm from the wall and can therefore only be used to a limited extent as a flush-mounted mailbox. Note that the mailbox can affect the statics and insulation.

It depends on your garden fence or the enclosure. If the distances to the holes are suitable and the garden fence is stable enough to hold the mailbox, installation is possible. Use appropriate fastening material.

The mailboxes are not scratch sensitive.
