Fire Safety
For reasons of fi re safety is it important to observe the instructions below before installing the stove.
1. If the fl oor around the stove is made of combustible material, you must use a fl oor slab. The fl oor 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 100 cm between the stove and combustible objects such as curtains, wooden
objects (cupboards and paintings) and glass objects. Keep the same distance from the fl ue tube.
3. Wooden construction parts within the radiation range of the stove (80 cm from the exterior of the stove) must
be covered with fi reproof material.
4. If the fl ue tube goes through a ceiling and/or roof that consist of fl ammable materials, the ceiling and the roof
must be covered with fi reproof materials all around (about 80 cm). Pay also attention to joisted fl oor 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 100 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, fi re-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 27).
9. Avoid heat transmission when placing the stove. Heat transmission of a burning stove can penetrate the wall
and even cause fi re damage on the other side of the wall. Prevention is better than cure.
Installation
The Oak is tested in accordance with the international EN 13240 standardization, and has an extra additional
standardization for optimally environment-friendly heating devices related to fl ue gases. The stove can be
connected to a fl ue tube to which several stoves are connected. The fl ue tube has a diameter of 150 mm.
Supply of combustion air
The stove must have enough supply of fresh combustion air. If necessary, make an extra air supply opening as
close to the stove as possible to avoid draught. An extra opening for air supply is always required if:
•
the space has a heat recovery system.
•
the space has a central exhaust system.
•
there is a cooker hood in the same space.
The air supply opening must be closable if it goes through a fi re-resistant wall.
When there are several combustion devices in the same space there must be
enough air openings to guarantee proper combustion.
External air connection
The external air connection has a diameter of 100 mm wide. A connection can be
fi tted at the lower back of the stove. If the external air supply shaft is built through
a fi rewall, then the air supply must be able to be shut. If the connection is longer
than 1 meter, including a 90 degrees turn, the diameter of the supply must be
widened consequently.
Connecting the stove
The Oak is a high-performance wood burner. Its minimal weight – including the
2 m long pipes for smoke exhaust (smoke vent) – can be at least 85 kg. Therefore,
please make sure before starting to build up, that its designated position in the
house (the wall where you want to connect the standing up oven, or the fl oor
on which it is to be placed) is able to carry its weight! Before you start, read the
