Regulating the combustion air

All RAIS stoves are equipped with a one-handed operating lever for regulating the

damper. The stove-specic regulating mechanisms can be seen on the diagrams.

Primary air is the combustion air added to the primary combustion zone, i.e. the bed of

glowing embers. This air, which is cold, is only used in the lighting stage.

Secondary air is the air which is added in the gas combustion zone, i.e. air which con-

tributes to the combustion of the pyrolysis gases (preheated air, which is used for the

cleaner glass system and combustion). This air is sucked through the damper under the

combustion chamber and is pre-heated through the side channels and then emitted as

hot scavenging air onto the glass. The hot air rinses the glass and keeps it soot-free.

The tertiary channel, which can be seen at the the top of the combustion chamber to-

wards the back, serves to combust the nal gas residues.

By setting the interval between position 1 and 2, the energy content in the rewood is

used optimally, as there is oxygen for combustion and for the burning of the pyrolysis

gases. When the ames are a clear yellow the damper has been set correctly. Finding the

correct position comes with time after you have used for stove for a while.

It is not recommended that you turn it down completely. A mistake commonly made is

shutting the damper too early because it feels too hot. This results in dark smoke ema-

nating from the chimney and in the caloric value of the rewood not being used to its

fullest.

Drying and storage

Drying wood takes time: proper air drying takes approx. 2 years.

Here are some tips:

Store the wood sawn, split and stacked in an airy, sunny place, which is protected

against rain (the south side of the house is particularly suitable).

Store the rewood stacks at a hand’s breadth apart, as this ensures that the air owing

through takes the moisture with it. Avoid covering the rewood stacks with plastic, as

this prevents the moisture from escaping. It is a good idea to bring the rewood into the

house 2-3 days before you need it.

Control

If the ash is white and the walls in the combustion chamber soot-free after the stove has

been used, the air regulation was set correctly and the wood was suciently dry.

Using the wood burning stove

Adjustment of air damper

The damper has 3 settings

Position 1

The air damper is closed, which means no air supply.

Position 2

Push the lever to the right until it stops. This position

gives full secondary air.

During normal stoking the lever is set between posi-

tions 1 and 2.

When the ames are clear and yellow, the damper is

set correctly, i.e. resulting in a slow/optimal burning.

Position 3

Lift the lever upwards and push to the right. The air

damper is completely open and gives full primary and

secondary air. The position is for the lighting stage

and is not used under normal operation.
