Installation
15 Värmebaronen Vedolux 55
Check
The installation engineer checks that:
• the system is full of water.
• all pipe connections are leakproof.
• the flue pipe connection to the boiler and chimney is
leakproof.
• the filling/drain valve is properly closed.
• the safety valves work correctly.
• necessary valves are open.
• the circulation pump is working with the correct flow
direction.
• the correct temperature is set on the charging
thermostat.
After installation, check with the installation engineer
that the system is in perfect condition.
Ask the installation engineer to demonstrate the control
and functions so that you know how the system works
and must be maintained.
Wood firing
Vedolux 55 has a ceramic grate and secondary
combustion chamber. The boiler works according to
the principle of inverted combustion. Used correctly,
the boiler produces very good combustion of wood
and gases and therefore has high efficiency and a low
environmental impact.
Wood firing involves more than just lighting the wood.
The firing technique is essential to the result.
Wood
Hardwood generally has a higher energy content than
softwood. However, it is important for the wood to be
dry with a moisture content of 16
±
8%.
If the wood is damp, a large part of its energy is used to
dry it, combustion is impaired and the risk of tar coating
increases.
On account of its high acid content, firing with oak for
extended periods of time should be avoided. Oak should
be stored for at least three years before firing.
The pieces of wood must be adapted to the combustion
chamber. The length should be approximately 20 in. and
the thickness approximately 6 in. so that three pieces
have room on the width of the grate.
To allow the wood time to dry, it should be felled at
least one firing season in advance. An alternative is sour
felling, which involves the tree being felled in the spring
when the leaves have just come out. Wait a few weeks
to trim and split the wood. The leaves will have withered
and withdrawn moisture. After drying for another few
weeks, the wood has 25-30% moisture content.
After cutting, the wood must be split. The more it is
split, the faster and more easily it dries. For pieces of
wood that are hard to split, the bark can be peeled off to
allow them to dry faster. Fresh wood is easiest to split.
The wood must not lie directly on the ground as it
will then absorb moisture instead of drying. It should
preferably be stored under a roof but so that the sun
and wind are able to dry it. Finally, it should be dried in
the boiler room two to three weeks before it is used.
After this, the moisture content is down to approximately
20%.
