Operation and care
RISK OF BURNS
Do not open the boiler hatches if the fan is not run-
ning and a fire is burning in the boiler. If you are not
sure whether a fire is burning in the boiler, first open
the bypass damper then open the firewood hatch a
couple of centimetres very carefully.
There is a risk of flames exiting through the hatch,
so take the greatest possible care!
Ceramic - combustion tunnel
The ceramic grate and combustion tunnel are wearing parts that
will have to be replaced over time. Wearing parts are not covered
by any guarantee. Small cracks in the ceramic are not abnormal
and no action is necessary.
To increase the service life of these parts, follow these instruc-
tions:
• Do not remove the ceramic when cleaning the boiler combustion
chamber.
• Scrape the ceramic gently and carefully when removing ash from
the boiler.
• Leave a couple of centimetres of ash as a protective layer on the
grate and the combustion tunnel.
Pieces of charcoal from the previous burning cycle can be left for
the next cycle.
• Only use “real” wood, avoiding plastic, treated timber, refuse,
etc.
• Place the wood in the boiler, do not throw it in.
• If the boiler/ceramic is new or if the boiler has not been used for
a while, light a small fire to heat the ceramic and remove any
moisture.
Safety valves
In order to preserve the safety function, the safety valves for the
domestic hot water system and the heating system must be oper-
ated regularly, around four times a year.
Open and close the safety valve manually around four times a year,
checking that a small amount of water escapes and that the valve
closes again properly. The pressure-relief device is to be operated
regularly to remove deposits and to verify that it is not blocked.
Also check that there is sufficient pressure in the system. If neces-
sary, add more water.
Venting
Regularly check that there is sufficient water in the heating sys-
tem.
Air may remain in the system for a while after installation, so
bleeding should be repeated a few times. After bleeding, check the
pressure and add water if necessary.
Water pressure in the system
The pressure required in the heating system depends on the height
difference between the lowest and highest points in the system, the
static head. If the difference is 5 metres, the pressure is 0.5 bar, if it
is 10 metres, the pressure is 1 bar.
The necessary pressure in the heating system depends on the
height difference between the highest and lowest points in the
system, the static head.
The pressure in a heating system varies with the
temperature, so only add water if it is necessary.
The volume of water changes with the temperature, and the
change in volume affects the pressure in the system. The higher
the temperature the greater the volume and the higher the pres-
sure. The expansion vessel takes up the changes in volume. The
flow temperature – and therefore also the pressure – is higher in
the summer than the winter.
Unvented expansion system
The pressure in the unvented expansion vessel should be checked
at intervals of several years. The vessel must not be exposed to
any pressure from the heating system.
Overheating protection
The overheating protection, which stops the fan if the boiler
temperature is too high, is reset on the boiler control panel. It is not
possible to reset until the boiler temperature has dropped below
95°C.
If there is a risk of freezing
In severe cold weather, no part of the heating system should be
turned off as this would involve a risk of burst pipes.
Never start a burning cycle if you suspect that any part of the heat-
ing system might be frozen. Call the installer.
If the heating system will be turned off for an extended period, the
water should be drained.
Draining the boiler
The boiler must not be running while it is being drained.
Close the valves to the heating system.
Run the water to a floor drain via a hose connected to the boiler
drain valve
.
Allow air into the system by opening the boiler safety valve.
The drain valve for the heating system must be located in a con-
venient place.
Boiler cleaning
Keep the boiler clean and tidy.
Alkaline cleaning agents are useful for removing soot marks from
the boiler. Do not use strong solvents.
Pellet burner
For optimum reliability and efficiency, it is essential to check and
adjust the burner regularly.
Power failure
If there is a power failure, the fan will stop and the output of the
boiler will fall. In around 20 minutes, the output drops from 100%
to approximately 10%. If Värmebaronen’s instructions were fol-
lowed when the accumulator tanks were connected, this output
can circulate naturally to the accumulator tanks.
