must have a diameter of 150 mm.
•
Any bends in the flue tube must not exceed 45 degrees.
•
Ensure that the chimney tube can discharge the flue gases adequately, properly and safely.
Fire Safety
For reasons of fire safety is it important to observe the instructions below before installing the stove.
1. If the floor around the stove is made of combustible material, you must use a floor slab. The floor slab must
measure at least: - 50 cm from the stove on the front side of the door - 30 cm from the stove on the sides
of the door.
2. Keep at least a distance of 80 cm between the stove and combustible objects such as curtains, wooden
objects (cupboards and paintings) and glass objects. Keep the same distance from the flue tube.
3. Wooden construction parts within the radiation range of the stove (80 cm from the exterior of the stove)
must be covered with fireproof material.
4. If the flue tube goes through a ceiling and/or roof that consist of flammable materials, the ceiling and the
roof must be covered with fireproof materials all around (about 80 cm). Pay also attention to joisted floor
layers and any electric wiring.
5. Keep a distance of at least 50 cm (in all directions) between the stove and supporting steel construction
parts.
6. Shield off all combustible materials within a radius of 80 cm from the stove openings with non-combustible
materials.
7. Never cover the chimney breast with combustible material (e.g. paper covering).
8. The wall behind the stove must consist of, or be insulated with, fire-proof materials. The insulation material
must resist a temperature of 700 °C and have a density of 80 kg/m3. Please see for insulation materials
table page 29).
9. Avoid heat transmission when placing the stove. Heat transmission of a burning stove can penetrate the
wall and even cause fire damage on the other side of the wall. Prevention is better than cure.
Installation
The Black Diamond stove is tested in accordance with the international EN 13240 standardization and has
an extra additional standardization for optimally environment-friendly heating devices related to flue
gases (Section 15a B-Vg. Des BmfWA). The stove can be connected to a flue tube to which several stoves are
connected. The flue tube has a diameter of 150 mm.
Supply of combustion air
The stove must have a sufficient fresh supply of combustion air. To avoid draft, make if necessary an extra air
supply opening as close to the stove as possible. An extra air supply opening is definitely required if:
•
the room has a heat recovery system.
•
the room has a central exhaust system.
•
the same space has a cooker hood.
The air supply opening must be sealable if it goes through a fire-resistant wall. If there are several heating
devices in the same room there must be enough air openings to guarantee proper combustion.
External air supply
The tube for supplying fresh outside air has a diameter of 100 mm. The air supply duct can be placed with
a connection at the bottom. If the external air supply duct goes through a fire-resistant wall, the duct must
be sealable. If the duct is longer than 1 metre including a 90° bend, the diameter of the duct must be bigger.
Please see page 26 to read how to connect the external air supply.
Connecting the hearth
The Black Diamond is a heavy woodstove. The standing model weighs 150 kg, including the 2 metre flue tube.
Verify whether the wall or the floor onto which the stove is installed is strong enough to hold the weight.
