Operation.and.care
RISK OF BURNS
Do not open the boiler hatches if the fan is not running
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 instructions:
• 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 do-
mestic hot water system and the heating system must be operated
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.
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 system.
Air may remain in the system for a while after installation, so bleed-
ing should be repeated a few times. After bleeding, check the pres-
sure 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 16.4 ft., the pressure is 7.3 psi, if it is
32.8 ft., the pressure is 14.5 psi.
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 tempera-
ture, 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 tem-
perature the greater the volume and the higher the pressure. The
expansion vessel takes up the changes in volume. The flow tem-
perature – 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 tempera-
ture is too high, is reset on the boiler control panel. It is not possible
to reset until the boiler temperature has dropped below 200°F.
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 heating
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 conven-
ient 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 followed
when the accumulator tanks were connected, this output can circu-
late naturally to the accumulator tanks.
