Dear customer,

Thank you for purchasing of the appliance KVS MORAVIA - solid fuel range cooker with heat
exchange unit for connection to central heating hot water system. We trust that our product serves
you well. Some important principles should be observed during its operation. Therefore, in your
interest, carefully study this manual and operate the product according to the given instructions.
The 9100 appliance has a manufacturer issued declaration of conformity according to Section 12,
Article 3, of Law No. 22/1997 of the Czech Republic.

• Flammable fluids should never be used to fire up or increase the heat output of the cooker.

• Do not burn waste in the cooker. Use only recommended fuel types.

• The ash door should always remain closed when the cooker is in operation to prevent burnt

gases escaping. The burner door should be open only when re-fuelling or attending to the
fuel in order.

• The cooker cannot be used unless it is connected to a functioning water system even

during the summer months, otherwise the heat exchanger will be overheated and thus
suffer permanent damage.

• Remove ashes into fire-proof containers with lids! Be extremely careful when dealing with hot
ashes. Pay attention to fire safety!

• Do not use the appliance if it becomes faulty!

• If operation instructions are not followed, the cooker could be damaged. Do not attempt to

overwork the appliance. If the temperature in the oven surpasses 300°C, the temperature
gauge may stop functioning correctly and suffer damage.

• If metal panels produce strong sounds or fireclay degrades within the unit, these are
not subject to repair or claim. The reason for the sounds will be internal flexing of
metal sheets due to heat, they will eventually return to their original state once cooled.
This does not affect the safety or operation of the cooker.

• Any repairs of the cooker except cleaning and clearing of fireclay should be executed only by
an authorised specialist.

• All local regulations, including the rules on national or European standards, should be
observed during the installation.

• Use only spare parts approved by the manufacturer.

• Repairs of the cooker by persons not authorised by the manufacturer are not recommended

and will render guarantees and warranties void.

• The cooker should be attended only by an adult. While in operation the cooker should be
attended and checked regularly.

• The appliance should be installed by an outhorised specialist. No claims are accepted
in case of incorrect or amateur installation.

Important Information

Declaration

TYPE 9100-HEU 07/2014 2

The appliance – range cooker TYPE 9100 is designed for burning solid fuel for the purpose of
home cooking, baking/roasting or heating of the space in which it is installed as well as other spa­ces connected to the domestic central heating system, according to CSN EN 12815:2002 and
Amendment A1:2005. The unit can be connected to a chimney at the rear, side or top through an
opening at the hob top panel (see Drawing 1a). It is available in either left or right versions.
The appliance is suitable for short operational periods, so it is not possible to set the permanent­heat process with a shortest interval of fuel supply of 10 hours.

Fuel

This appliance is designed for combustion of solid fuel:

- recommended fuel is wood (max. diameter 200 mm, max. length 330 mm).

- the appliance also enables burning of other kinds of solid fuel (wood briquettes, waste wood,

brown coal briquettes, and brown coal blocks). However the operating conditions and parameters
of the appliance may differ from those with the recommended fuel. Please note that the technical
characteristics given above were based on a test wood fuel sample and using other fuel types will
alter these characteristics, energy output, fuel consumption, flue draught etc.
Make sure that the fuel is dry. It is not recommended to burn high-calorific fuels, which reduce the
service life of the appliance.

Grates

The cooker is equipped with two grates, upper (fixed) and lower (rotary). The upper grate is in
position to provide optimum fuel consumption when cooking in the summer regime. For winter use
we recommend that you remove this grate (Drawing 2) and take advantage of the increased
volume of the fire box. Burning thus will be carried on in the lower grate, which is manipulated
by the grate handle (Drawing 3). The water heat exchange unit is placed between these grates
and this allows when using upper grate to reasonably reduce the temperature of water during the
summer period.

Using the Grates

Moving of grates will allow the non-burnt ashes to fall through to the ash tray. This also increases
the combustion (primary) gases flow into the fire box. The grates can be agitated by moving the
grate handle back and forth. Large ash pieces that, due to their shape, do fall through the grate
should be removed when the fire is out by turning the grate with the handle (Drawing 3).
Sometimes grate manipulation is necessary when the upper grate is in operation, this can be
done with a poker.
Note: A number of cooker variants are supplied with a safety catch on the rotating grate, which
prevents the grate turning by itself. Before rotating the gate the safety catch should be pushed to
the left (Drawing 3).

Air Intake Regulation (Drawing 4)

The draught regulator built in into the ash door of the cooker provides controlled regulation of the
air intake and control of the fuel burning speed (heat output of the cooker). The regulation is
indicated by triangles. The lever positioned under the symbol ▲ means slow burning - air intake is
closed) while the position under ▲▲▲▲ corresponds to fast burning - air intake is fully open
(Drawing 4). While in operation the air inflow into the cooker should be uninterrupted by ensuring
air intakes are clear at all times. Do not use an air suction device to compensate for poor air flow
in a space where a cooker is installed.

Drawing 4

The Ash Extracting Door

When the cooker has been in operation for some time, soot will collect in the cooker parts of the
draught system (especially where coal has been used). This will eventually affect the draught and
may create problems while lighting the fire. It will also make operation of the cooker less
economical, especially when cooking in the oven.
In the course of cleaning take off the hob top plates, then remove the soot first from the sides
of the oven walls. Clean all the removed deposits through the ash extracting slot situated under
the oven door (Drawing 7). This can be done simply by using damp newspaper, for example.

Appliance hob top panel (variants)

1) The standards panel consists of two parts (Drawing 5):

Plate I. - a cast iron range hob with a round removable centre plate located directly under
the fire box. This plate is meant for fast cooking
Plate II. - a steel hob is located above the oven. This plate maintains a lower temperature
and thus can be used for slower cooking, simmering and keeping food warm.

2) The single-piece ground steel finish hob-top panel.

You should always use pots with flat bases.

Ignition Flap

The smoke flap is located under the Plate II. and is controlled by a handle at the rear of the top
frame marked with two positions :

Open position – Ignition and

intensive cooking
throughout the entire range area, Plate I. + II.
(Flap open)

Closed position – Baking in the oven and

cooking on the Plate I.
(Flap closed)
