For the property owner
Congratulations!
You have chosen a CTC V40 wood boiler that we hope
you will be very pleased with. CTC V40 is available
in two versions: one with automatic control of the air
supply and one with manual air supply.
Both boilers have powerful suction fans which provide
good combustion with low emissions. The efficiency is
over 90%.
The best system function is achieved by using a charge
group and mixing valve groups which control what
should be heated or which areas should be heated.
The boiler is designed to be installed together with buffer
tanks and must therefore not be connected for burning
directly to a heating system.

8CTC V40
For the property owner
Your home's heating installation
!The set heating curve is always given priority. The room sensor can only increase
or decrease the compensated flow temperature to a certain extent above the set
heating curve. Where operating without a room sensor, the selected heating curve
determines the flow temperature supplied to the radiators purely from the outside
temperature reading.
The House Heating Curve
The heating curve is the central part of the product’s control system. It is the heating
curve which determines the compensated flow temperature requirements for your
property dependent upon the outdoor temperatures. It is important that the heating
curve is correctly adjusted, so that you achieve the best operation and economy
possible.
One property requires a radiator temperature of 30°C when the outdoor temperature
is 0°C, whilst a different property requires 40°C. The difference between different
properties is determined by the radiator surface area, the number of radiators and how
well insulated the house is.
Adjustment of Default Values for the Heating Curve
You define the heating curve yourself for your property by setting two values in
the product control system. This is achieved by selecting the options Inclination or
Adjustment under the Installer/Settings/Radiator system menu. Ask your installer to
help you set these values.
It is extremely important to set the heating curve and, in some cases, unfortunately,
this process may take several weeks. The best way of doing this, upon the initial
start-up, is to select operation without any room sensor. The system then operates
using the outdoor temperature reading and the property’s heating curve only.
During the adjustment period it is important that:
• the night reduction function is not selected.
• all thermostat valves on the radiators be fully opened.
• the outdoor temperature is not higher than +5°C. (If the outdoor temperature is
higher when the system is installed, use the factory set curve until the outdoor
temperature falls to a suitable level.)
• the radiator system is operational and correctly adjusted between different
circuits.
Appropriate Default Values
During installation you can seldom achieve a precise setting for the heating
curve instantly. In this case, the values given below may provide a good starting
point. Radiators with small heat-emission surfaces require a higher primary flow
temperature. You can adjust the gradient (heating curve gradient) for your heating
system under the Installer/Settings/Radiator system menu.
Recommended values are:
Floor heating only Inclination 35
Low temperature system (well insulated houses) Inclination 40
Normal temperature system (factory setting) Inclination 50
High temperature system
(older houses, small radiators, poorly insulated) Inclination 60

9CTC V40
For the property owner
Adjusting the heating curve
The method described below can be used to adjust the heating curve correctly.
Adjustment if it is too cold indoors
• If the outdoor temperature is lower than 0 degrees:
Increase the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Increase the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
Adjustment if it is too warm indoors
• If the outdoor temperature is lower than 0 degrees:
Decrease the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Decrease the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
!If the values set are too low, this may mean that the desired room temperature
is not being reached. You then need to adjust the heating curve, as necessary,
following the method shown above.
When the basic values have been set more or less correctly, the curve can be
finely adjusted directly using the Room temp. shown on the home menu screen.
Description of inclination and adjustment
Inclination 50:
The value set is the outgoing temperature of the water supplied to the radiators at an
outdoor temperature of –15°C, e.g. 50°C. A lower value is selected where a radiator
system has large radiator areas (a low temperature system). Floor heating systems
require low temperatures. A low value should therefore be selected. The value must be
increased for high temperature systems to achieve a high enough indoor temperature.
Adjustment 0:
The adjustment means that the flow temperature can be raised or lowered at a specific
outdoor temperature.
Adjustment 0 means 20°C primary flow when the outside temperature is 20°C.
Adjustment -5 means 15°C primary flow when the outside temperature is 20°C.
For example:
Inclination 50 means that the temperature of the water supplied to the radiators will
be 50°C when the outdoor temperature is –15°C (if adjustment is set to 0). If the
adjustment is set to +5, the temperature will be 55°C instead. The curve is increased
by 5°C at all temperatures, i.e. it is parallel displaced by 5°C.

10 CTC V40
For the property owner
Examples of Heating Curves
You can see in the diagram below how the heating curve
changes with different Inclination settings. The gradient of
the curve shows the temperatures that the radiators require
at different outdoor temperatures.
Curve Inclination
The inclination value which is set is the primary flow
temperature when the outside temperature is –15°C.
Primary Flow Temperature
Primary Flow Temperature

Primary Flow Temperature
Outside Temperature
Outside Temperature
Outside Temperature
Heating off, out
Heating off, out

Outside Temperature
Adjustment
The curve can be parallel displaced (adjusted) by the
desired number of degrees to adapt to different systems/
houses.
An example
Inclination 60°C
Adjustment 0°C
In this example, the maximum outgoing primary flow
temperature is set at 55°C.
The minimum permitted primary flow temperature is 27°C
(e.g. summer-time basement heating or the floor circuits in
a bathroom).
Summer-time operation
All properties have internal heat gains (lamps, oven,
personal heat etc.), which means that the heating can be
switched off when the outdoor temperature is lower than
the desired room temperature. The better insulated the
house is, the earlier the heating from the heat pump can be
switched off.
The example shows the product set at the default value of
18°C. This Heating off value can be changed under the
Installer/Settings/Radiator system menu.
When the heat is switched off in this way, the radiator
pump stops and the mixing valve is shut down. The heating
starts up automatically when it is required again.

2. Firing
2.1 Reverse burning
The burning must last during a sufficiently long time, at sufficiently high temperature
and at sufficient turbulence (turbulence means that, with thehelp of baffles and
position of the air intake, thecorrect turbulence is achieved). This condition,
time, temperature and turbulence is often called the3Ts. Agood mixture of these
three provides good burning.
The flue gas fan ensures that the flame findsitsway down the grate, and with
the help of a controlflue the flame starts rotating.The fan sucks theairand the
flame on through the ceramics where theremaining gases are burned. The air
continues through the heat transfer pipes and out through the chimney.

15CTC V40
For the property owner
!It is both inappropriate and prohibited to heat with waste, chip boards, painted
wood, pressure-impregnated wood or similar, as these materials emit gases
which are very corrosive and hazardous when heated
2.2 Fuel
• Moisture content, type, size and cut of thewood is of importance for
burning and for the operation of the boiler, among other things the
output.
• Suitable moisture content is about 15-25%. Higher moisture content
gives lower output.
• The wood should be stored under roof or rain cover. The drier the
surrounding air is, the quicker the wood dries.
• The boiler is designed for 0.5 m wood and it is important that the wood
is chopped. Large, round logs do not dry as well and are therefore less
suitable as fuel. Suitable piece size is when 3-6logs can be placed
next to each other in the boiler.
2.3 Air setting
• CTC V40 with Lambda probe automatically sets itself for best burning
with both primary and secondary air settings.
• For CTC V40 without Lambda probe the property owner sets the
primary and secondary air settings. The primary and secondary air
settings are set at the factory at an average value which corresponds
with most wood types and moisture contents.
• With two dampers, the primary and secondary air can be set in
intervals between of 1 and 10 for desired combustion. Adjustment of
the inlet air is primarily done depending on the moisture content of the
wood.
• The boiler delivers about 40 kW in 2.5 hours of burning birch wood
with 20% moisture content.
• Efficiency can be increased by installing the “filling bodies”, “ filling
bodies it is a metal pole that you put inside the turbulators so that
the efficiency rises. It is important to ensure that the temperature
is not below 70 ºC, 1 meter down the chimney, in order to avoid
condensation.
For humid wood/large chopped fire wood:
Increase the primary air setting.
For dry wood/fine chopped fire wood:
Reduce the primary air setting.
Thesmoke should always have a transparent, lightgrey nuance.

For the property owner
!Appropriate quantity of wood means that, when the accumulator tanks are fully
charged, the wood in the boiler has all burned up.
!Plan the heating and wood inlay so that you utilize the boiler and the accumulator
system maximally
!It is important that, when loading the logs, you stack them as tightly as possible,
partly because you then get in more logs and can utilize the boiler maximally,
partly because you get more even and environmentally friendly combustion with
tightly stacked logs.
!At delivery the ceramics are not completely dried out.
This is done at the first firing. Therefore, during the first two hours, fire very care-
fully with small wood inlays only
!Too much wood gets the boiler up to max. temperature and the fan stops.
This can give non-desired emissions and possible cooling of the boiler with the
cooling coil cooling the boiler without the possibility of benefiting from this heat
2.4 Start up
In order to get a good combustion, the moisture content of the wood is
determining. There are two alternative ways to start combustion.
Alt. 1
1. Press the start button
2. Open the door.
3. Fill with wood so that the bottom is covered, approx 3-5 logs. Cover
with newspaper. Make a small newspaper “fuse” with which to light.
Continue to fill on logs to a sufficient quantity.
4. Light.
5. Close the doo
Alt. 2
6. Open the door.
7. Fill with starting wood/sticks and add newspaper. Continue to fill with a
few logs.
8. Light.
9. Press the start button, close the door and wait afew minutes in order to
get an ember bed.
10. Open the door and fill the boiler with wood tothe suitable quantity.
11. Close the door.

17CTC V40
For the property owner
2.5 Heating phase
• For CTC V40 Lambda: after filling withthe appropriate amount of wood,
the control systemof the boiler monitors the heating fully automatically.
• For CTC V40: the air is set before start. The ash door must not be opened
during heating.
2.6 Add firewood
Firewood is added as needed.
Please note: If the filling door is opened during firing, smoke and fumes will
escape into the room. Open the door a few inches and wait until the fan speeds
up before opening the door fully.
2.7 Shut down
When the wood has burned down, the output decreases and the flue gas
temperature drops. When the flue gas temperature drops to set value, the fan
and the charge group/charge pump stop.
!Do not open the filling door when the current boiler temperature or flue gas
temperature is at maximum, because the flue gas can ignite in the fuel cham-
ber.
!Any embers in the ashes could ignite. Always store ashes in a safe manner.
!The ash door must not be opened during firing.
