UNIVERSAL-6 70
At what temperature does the convection fan cut in?
If the appliance is fi tted with a convection fan, this can be regulated using an built-in
dimmer.
The fan does not have any automatic regulation based on the appliance temperature.
How do I know if I'm heating correctly?
Follow the instructions in this manual.
The fl ames should play softly across the wood and the wood should burn evenly.
Once the fuel has been burning for a short time, the smoke from the chimney should be
almost translucent.
What is wrong with a smoking chimney?
A seriously smoking chimney means that combustion is less than optimum.
There may be a number of reasons for this. If the appliance has only just caught on, or
has recently been topped up, some smoke is normal. By opening the door for a short
period, the wood will catch fi re quicker and the smoky period will be shorter.
If you leave the appliance door open, and especially if you burn damp wood, the result
will be a lot of smoke. In both cases, the combustion temperature is too low. This leaves
numerous dangerous compounds intact, which means more deposits in your chimney
and more waste into the environment.
What should I do if the wood does not catch fi re?
This probably means that the wood is damp. Remove the wood and replace it with dry
wood. If necessary, make a fi re with wood briquettes. They are always dry (they have a
moisture content of <10%).
The wood burns up too quickly. What should I do?
Ensure that air cannot get in underneath the fuel. Move the combustion air supply slider
towards the " - " position. (The primary air supply is now closed.) Under these
conditions, the layer of ash should no longer burn bright orange/white but red.
If there is a draught (due to strong wind), air intended as secondary air for above the
fuel may enter through the openings above the door and fl ow straight down beneath the
wood. Also slide the combustion air supply slider tighter shut.
There may be too much of a draught in your chimney, particularly if it is very high (in
excess of 8 m). Ask your supplier to fi t a check valve or damper. This may not be
possible in all cases.
