Operation
12 Unilux-7 55

6.2 First use of the appliance
Caution:
• Make sure there is sufficient ventilation in the room in which the appliance
is installed.
Note:
The appliance has a heat-resistant coating. When you use the appliance for
the first time, the coating can cause an unpleasant, but harmless smell.
After first few times of use of the appliance, a light deposit on the inside of the glass may
occur caused by curing of the paint. This can be removed with glass cleaner or ceramic
hob cleaner.
6.3 Firing the appliance
6.3.1 First load and ignition
At the beginning the appliance and chimney are cold. It is important that both the
appliance and chimney reach a temperature that guarantees a good functioning of the
appliance. A too low temperature results in incomplete combustion and a poor chimney
draught. To avoid this do the following:
Warning:
Do not use the appliance when there is fog or haze or no wind.
1. Put the control lever in the far right position.
2. If applicable, open the valve in the external combustion air supply line.
3. If applicable, open the chimney valve completely.
4. Open the door of the appliance.
Operation
Unilux-7 55 13

5. Put minimum 4 wood logs crosswise on the floor of the combustion chamber.
6. Put some kindling wood and 1 or 2 firestarter cubes on top of the wood logs.
7. Put some kindling wood above the firestarter cubes.
8. Light the firestarter cubes with a lighter or a match.
9. Close the door of the appliance.
After approximately 20 minutes the wood logs burn. Dependent on the quality of the
chimney the wood logs burn for approximately 1 to 1.5 hours. Do not open the door of the
appliance before the last flames have almost disappeared.
Operation
14 Unilux-7 55

6.3.2 Reload with fuel
Caution:
If there is insufficient burning material in the firebed to light a new fuel charge,
excessive smoke emission can occur. Refueling must be done onto a
sufficient quantity of glowing embers and ash to make sure that the new fuel
charge will ignite in a reasonable period. If there are too few embers in the fire
bed, add suitable kindling to prevent excessive smoke.
Note:
The procedure hereunder is a general description. The best reloading
moment is dependent on the flue draught. A high flue draught requires
reloading when the flames have completely disappeared. If the flue draught is
low, reloading must be done when there are still flames.
1. Wait until the last flames have almost disappeared.
2. Set the control lever in the far right position.
3. Open the door.
4. Reload the appliance with 2 wood logs, put flat on the combustion chamber floor.
Use the recommended amount of fuel. Refer to chapter 5.2 .
5. Close the door.
6. After ignition of the fuel, move the control lever to the left to a position that gives a
quiet burning fire.
Operation
Unilux-7 55 15

6.3.3 Control the burn process
Control the burn process with the control lever. This lever controls the amount of primary
combustion air and both the secondary combustion air and airwash amount.
Control lever in the far right position:
primary air inlet maximum open
secondary air inlet maximum open
airwash inlet maximum open
Control lever in the center position:
primary air inlet is closed
secondary air inlet maximum open
airwash inlet maximum open
Control lever in the far left position:
primary air inlet is closed
secondary air inlet is closed
airwash inlet is closed
Warning:
Setting the control lever in the far left position (all air inlets closed) when the
fuel is burning leads to excessive emission of hazardous gasses (example:
carbon monoxide) and soot deposit on the glass of the door and in the
chimney. Never close the air inlets when the fuel is burning. Always keep the
secondary air inlet and air wash inlet open by setting the control lever
somewhere in-between the center position and the far left position.
Caution:
Continuous firing with the primary air inlet fully open (control lever in the far
right position) causes a white-hot fire that can damage the appliance. Use the
primary air only during the first fuel load and for ignition of a new fuel load.
Operation
16 Unilux-7 55

6.3.4 Increase the flue draught
Warning: Do the procedure hereunder when you have made sure the
appliance has cooled down and there are no glowing embers.
A low flue draught is caused by too much flow resistance. This causes insufficient flow of
the flue gas in the chimney. Do the next steps to decrease the flow resistance
1. Loosen the nut above the heat shield with a 3 mm hexagonal key and a 10 mm fork
spanner. Unscrew the socket screw. Make sure the nut stays attached to the socket
screw.
2. Push up (1) the front of the heat shield and pull it forward (2) and move downward to
a vertical position (3).
3. Remove the upper baffle from the appliance.
Operation
Unilux-7 55 17

4. Remove the break strip from the baffle with a pair of pliers.
5. Do the steps 1 to 3 in opposite order to put the upper baffle in the appliance
6.3.5 General firing tips
• The appliance works best when it has heated up as described in chapter
6.3.1 .
Insufficient heating up leads to a low chimney draught, black deposits on the glass
and incomplete combustion. Good combustion is recognized by bright orange flames,
invisible smoke and no soot deposits on the glass. Use the control lever to get good
combustion. Refer to 5.1 for advice on the required fuel quality.
• Make sure the door of the appliance is closed when in use. Only open the door for
ignition and to refuel.
• Do not remove all the ashes. An ash layer in the combustion chamber forms a heat
insulating layer, that helps the fuel to ignite easy.
• Do not set the control lever in the far left position (all combustion air inlets closed)
when the appliance is used. This will cause severe smoke development, soot
formation and increases the chance of a chimney fire.
• After the first load, do not overload the appliance with fuel. Refer to 5.2 for the
recommended amount of fuel. Too much fuel leads to incomplete combustion, soot
formation and a chance of a chimney fire.
