1.1. Iron stove structure
The air circulating between the heating chamber and
the outer casing efficiently heats the room.
The sturdy and extremely tight cast iron doors are
equipped with a vertical latching device.
The iron stoves have a frame of steel board and an
outer casing of painted steel. The heating chamber
is made of either cast iron protected by firebrick at
the bottom.
The extended flame channel in the top part of the
heating chamber contributes to the efficiency of the
hot plates in the iron stoves and makes the stoves
excellent for heating room air.
Read the instructions carefully before using
the iron stove.
For the fireplace to work correctly and draw air
well, ensure that there is enough replacement air
in the room, especially if mechanical ventilation is
in use.
2.1. Warnings
Burning too big fire in the stove leads to an
•
excessive risk of fire and too high temperatures
in fireplace structures. Overheating may chan-
ge the shape of the heating chamber and the
colour of the casing.
Whenever a iron stove is heated, the steel ca-
•
sing becomes extremely hot. It is important to
ensure that children do not come into contact
with a hot furnace.
No objects should be kept on top of stoves. Dry-
•
ing clothes on, above or near them is prohibited.
Do not store wood or other inflammable mate-
•
rial in the space below of the fire chamber.
Never leave a fire burning unattended. Before
•
closing the flue, make sure that there are no
smouldering embers in the fireplace that might
lead to a build-up of carbon monoxid.
2.2. Fuel
Harvia iron stoves can use wood as a fuel (with a
length of 20–30 cm). The fuel must be dry.
The following may not be used as fuel: plas-
tics, combustible liquids, and waste including
glue, solvent or plastic.
2.3. Heating
The heating of a new stove should be started care-
fully. Because the substances that evaporate from
the painted surfaces may initially release an odour
characteristic of paints, air the room well.
Keep small pieces of wood, along with kindling
such as birch bark and newspaper, close at hand.
Start off with only a small amount of firewood.
1. Place the wood pieces crosswise (in the middle
of the heating chamber) and stick the kindling
between the lowest pieces of wood.
2. Open the damper and close the control open-
ings for combustion air.

2. USINg HARVIA IRON STOVES
Only use replacement parts recommended by
the manufacturer. Unauthorised modification
of the iron stove is prohibited.
1.2. Input of combustion air
In the Harvia iron stoves the air is conducted through
a channel into the front part of the chamber, which
is designed to direct the air into the embers.
The amount of air needed for burning can be ad-
justed from a knob under the doors.
3. Set fire to the kindling. Once the wood has
caught fire, close the doors of the stove and
open the regulating outlet for combustion air.
The stove is not intended for use with the
stove door open. The draught may be poor at
first, because the flue is still cold, but it will
improve as the flue warms up.
4. Keep an eye on the fire and adjust the combus-
tion air as needed.
5. When the first batch has nearly burned down
to embers, add more wood to the furnace, two
to four pieces at a time. When adding wood,
close the outlets for combustion air and open
the chamber door carefully. Quick changes of
air current in the chamber may cause smoke to
seep into the room.
Be careful with the door handles of the
heating chamber as they may become
scalding hot.
Place new wood horizontally on top of the
embers – parallel with the side wall of the cham-
ber – as far as possible from the glass doors.
6. After adding the wood, close the doors and
open the regulating outlet for combustion air.
7. When the embers turn darker and ashes start
forming on top, turn the embers around to en-
sure that they burn down.
8. The damper must not be closed until the
embers have completely burned down and no
more blue flames can be seen. Closing the
damper too early poses a risk of carbon mon-
oxide.
After the first rounds of heating, you should also
start keeping an eye on the ash forming in the heat-
ing chamber. The embers may fall against the doors
if there is too much ash in the chamber.
2.4. Maintenance
Iron stove
We recommend removing the ash before each
•
time of use. Get a metal container, preferably
standing model, to put the ash in. As the
removed ash may include hot embers, do not
keep the ash container close to combustible
material.
