G
Device Functionality
The REMKO ALLMAT works on the principle of subheating using exhaust post-combustion. The feeder
chute and furnace are completely lined with high-quality
refractory bricks.
The unit has a generous feeder chute which opens upwards. It can be filled with fuel reserves if the unit is to
be operated over a longer time period.
The feeder chute does not act as a furnace or combustion chamber. The fuel slides out of the feeder chute
into the furnace depending on the burn rate.
If heat is only necessary for several hours during the
transition phase, the unit can also be fuelled with
smaller quantities of fuel directly into the furnace. This
does not adversely affect the low-smoke combustion,
heating performance or effectiveness.
The standard air circulating fan is automatically
switched on and off by a built-in thermostat. This ensures that only heated air is blown out.
To prevent damage to the unit resulting from overheating, do not unplug the unit during operation.

Fuel
Units for solid fuels up to 15 kW of rated heat output
must be operated with low-smoke emission.
This requirement is met when the system is operated
with air-drying fuels that generate little smoke.
The unit may be fuelled with the following in accordance
with § 5 of the ordinance on small furnace systems 1.
BImSchV (German federal emission protection laws):
1. Coal, non-pitch coal briquettes, coal coke,
2. Lignite, lignite briquettes, lignite coke,
3. Peat briquettes, combustible peat,
3a. Charcoal, charcoal briquettes,
4. Non-treated pieces of wood with attached bark.
In slow combustion mode, solids fuels must be burned
so that the exhaust plume is lighter than gray scale
value 1 of the Ringelmann scale.
Important information about prohibited fuel types!
No fuels may be burned that contain chemical, PVC or
similar additives, e.g. binding agents.
These types of materials, when burned, release ag-
gressive and toxic steam that damages the environment and destroys the unit and the exhaust system.
Burning the materials above or similar materials is not
only strictly prohibited, it also makes the guarantee
completely null and void.
Firing egg-shaped coal briquettes and other fuels
which carbonise at low temperatures are also not permitted!
Several calorific values.
approx. calorific value (dep. on consistency) kW/kg
BIMATIK Heat Output Regulator.
The REMKO ALLMAT is equipped with a BIMATIK thermal output regulator.
This automatically regulates the heat output that has
been set on the regulator knob in the “min / max” area.
A temperature sensor records the respective temperature of the heat exchanger and automatically distributes
the combustion air accordingly.
If the temperature falls below the set value, more combustion air is supplied to the furnace through the air
slide plate. If the unit again reaches a higher temperature than is set, the amount of combustion air being
supplied is reduced.
This regular cycle keeps the heat output within the selected range.
Proper functioning of the heat output regulator is, however, dependent on the operating conditions of the unit
as well as a steady and stable chimney draught.

Installation
The unit may only be installed in accordance with the
applicable legal regulations and the ordinance on heating systems.
The unit must be securely placed on a non-combustible
surface outside of traffic zones.
A safety zone of 1 m must be maintained around the
unit.
The unit may not be placed too close to the wall or in a
corner so that any cleaning and maintenance work can
be performed in an unrestricted manner.
We recommend installing the unit on a sufficiently large
plate made of non-combustible material.
The unit must be set up and operated in such a way that
people are not exposed to exhaust or radiant heat and
fires are prevented from occurring.
The unit may not be set up and operated in rooms and
areas susceptible to fire or explosions.
The unit may not be operated in rooms that have above
or below average pressure or rooms where this can occur.
Heating units for solid fuels that remove combustion air
from the room where the unit is installed may not be set
up in rooms where ventilation systems or fans exhaust
or suck in air.
The exhaust connection may only be used with approved chimneys. The chimneys can be made of bricks
or metal. If the chimney is made of brick, make sure
that the exhaust pipe does not protrude into the chimney, thereby having an adverse effect on the crosssection.
The chimney must have an adequate chimney
draught.
G
If a chimney draught stabiliser is not in use, the effective
height of the chimney must be at least 4 m. By using a
chimney draught stabiliser (accessory, ref. no.
1034250), the chimney can usually be constructed using
the most ideal design. The chimney draught stabiliser
generates the necessary upwards propulsion (chimney
draught ).
The chimney’s diameter may not be smaller than 150
mm Ø.
The unit connection must be tightly sealed and secured
against inadvertent loosening.
Rivets or bolts.
Exhaust lines which bend in several places must
be extended accordingly.
G
The unit may only be set up and operated in rooms if
there is an adequate supply of air for combustion and
the exhaust is expelled via exhaust flues.
A natural air supply sufficient for combustion exists
when, for example, the room content in m³ is equivalent
to at least 10 times the rated heat output in kW of all
heating units in operation in the room and natural air
ventilation is supplied through windows and doors or the
ratio of room content to overall heat output does not fall
below 4 m³ per kW.
If necessary, a separate combustion air supply must be
installed from outside.
Good natural ventilation exists when, for example,
the room content in m³ equals 30 times the rated
heat output of all units in operation in the room and
natural ventilation is supplied through doors and
windows or
there are non-closable openings for air output and
intake close to the ceiling and floor whose size in m²
equals at least 0.003 times the rated heat output in
kW of all heating units in operation in the room.
Expulsion of combustion gases
Chimneys
The unit must be attached to chimneys.
Chimneys are structural systems either in or on build-
ings whose only function is to expel exhaust from furnaces above the roof.
The construction of chimneys always requires a permit.
G
If the roof is also the ceiling of the room where the unit
has been installed, the chimney can be made of sheet
steel. Each furnace must have its own chimney. Merging sheet steel chimneys is prohibited.
The chimney must be placed in a tube jointing sleeve
when passing through wall or roof penetrations so that it
can expand freely when heated.
The following are important when planning and constructing:
◊ The applicable furnace system ordinance.
◊ The applicable regional building code.
The unit is designed in such a way that it can only function correctly if gases are properly expelled. The exhaust connection must be installed correctly and comply
with the relevant standards.

Assembly instructions:
1. Disassemble the regulator knob and remove the lining plates of the unit.
2. Remove the defective heat output regulator.
3. Insert the new heat output regulator.
Do not damage the capillary tube or temperature
sensor.
4. Turn the BIMATIK regulating spindle to the left until it
clicks into the “min” position.
5. Adjust the air slide plate on the adjustment spindle so
that the air intake opening closes without resistance.
Secure with counter nut.
Chimney Draught Stabiliser
To ensure that heating operation is steady, the chimney
draught must remain constant and stable in all operating
conditions and in each type of weather.
A constant chimney draught also ensures effective expulsion of flue gases and optimum suctioning of combustion air.
Changes in the temperature of the exhaust, in the temperature of the outside air, in the direction of the wind or
gusts usually cause the chimney draught to rise or fall.
The chimney draught stabiliser increases and stabilises
the upwards propulsion (chimney draught) if it is insufficient.
The chimney draught stabiliser stabilises operating conditions when:
◊ The unit heats up.
◊ The weather is unfavourable.
◊ The height of the chimney is inadequate.
◊ The chimney draught is inadequate.

Starting
Important hints about operating the unit for the first
time!
Because burned refractory bricks also contain residual
moisture, proceed as follows when operating the unit for
the first time:
1. Heat the unit up gradually.
2. Open the filling flap a little bit while the unit is cooling so that the steam from the refractory bricks can
escape.
This prevents the refractory bricks from splitting or
breaking later.
3. Repeat this heating process 3 to 4 times to get rid
of any remaining moisture from the refractory bricks.
Preparations prior to heating.
1. Connect the unit plug to a power
socket with the right connection.
230V/1~ 50Hz.
2. Keep in mind that the circulating air
fan automatically switches on and off
depending on the unit temperature.
3. If you are using a chimney draught stabiliser, plug it
into a power socket with the right connection.
The 230 V / 1~ / 50 Hz power connection is only
necessary for heating mode.
4. If applicable, adjust the draught limiter of the chimney draught stabiliser using a draught gauge.
Only necessary for initial operation.
5. Open the waste gas flap in the waste gas connection.
6. Set the BIMATIK heat output regulator to the “max.”
position with the regulating knob.
7. Clean the furnace and empty the ashpan.
Not necessary for initial operation.
The unit may not be unplugged from the power
supply while in heating mode as this can damage
G
the unit due to overheating.
Heating Up the Unit
1. Ignite the fire with paper or fire starter and small
pieces of wood on the fire grate.
Never use petrol, thinning agents or other highly
flammable materials.
G
2. Once the kindling has begun to burn, add a small
amount of fuel.
3. Wait until this has burned through. Now the prefuelling process can be done continuously.
4. Keep all furnace doors closed while the unit is heating up and during operation.
5. Only open the air slide plate for secondary air (item
2 in the figure under “Device Functionality”) a little
bit to prevent air blockage.
Heating Mode
1. Fill up the feeder chute completely once approx. 50%
of the fuel from the pre-fuelling process is burning.
2. Adjust the primary air slide plate in increments to
the appropriate setting for the fuel.
3. Set the heat output in the “min / max” range using
the regulating knob of the BIMATIK heat output
regulator.
4. Adjust the flue gas flap in the waste gas connection
according to the fuel being used and the chimney.
draught.
If you are using a chimney draught stabiliser, the
flue gas flap must always be open all the way.
G
5. Keep in mind that the circulating air fan only
switches on automatically once the target temperature has been reached.
6. Only open the filling flap to add more fuel once the
initial fuel has burned down to glowing embers.
Now the gasification process is complete. During
this process, problems can occur with smoke if the
feeder flap is opened while burning wood (similar for
other fuels). It is now possible to add more fuel without a problem.
7. Stoke the fire grate with pokers to keep it clear of
ash from time to time depending on the fuel and
amount of ash during heating operation; empty the
ashpan.
Important Information on Burning Wood.
Wood is a fuel that is very gaseous and produces large
flames when burned. With enough combustion air, it
burns extremely rapidly. As a result, when wood is in its
final burning stages, it is not possible for combustion to
be weak or slow until it has become glowing embers.
Only after it has become embers continued burning can
be delayed by lowering the supply of combustion air via
the BIMATIK heat output regulator and closing the primary air slide plate.
When adding more pieces of wood, be careful not to
damage the refractory.
Information on Refractory Lining.
The life expectancy of the refractory lining is largely dependent on the operating conditions and how the unit is
treated.
Due to natural temperature fluctuations, small cracks
can appear in the refractory bricks but this does not adversely affect the functioning of the unit.
Do not subject the refractory to mechanical overload, e.g. from stoking the fire or throwing in fuel.
Damaged or broken refractory bricks are not cov-
G
ered by the guarantee.

to keep the unit functioning properly.
◊ Keep the unit free of dust and other deposits.
◊ Use a clean, slightly moist cloth to remove external
dirt from the surface of the unit.
Never place the unit under a direct stream of water.
◊ Do not use aggressive cleaning agents or those
which contain solvents.
◊ Use only suitable cleaners even when the unit is ex-
tremely dirty.
◊ Regularly check protective mechanisms to ensure
that they are working properly.
◊ Regularly check the air suction and blow-out grilles
for dirt.
Clean if necessary.
◊ Make sure that the unit is being safely operated in
accordance with the operating condition or when
necessary.
At least once a year.
◊ Make sure to comply with the maintenance and serv-
ice intervals.
The unit is not generating enough heat.
◊ The ashpan is too full.
No combustion air is reaching the furnace.
◊ There are ashes, cinders or other combustion resi-
due on the fire grate.
◊ There is soot or flying ash in the exhaust chimneys
or pipes.
◊ The flue gas flap 7 is not open wide enough.
◊ The BIMATIK setting is too low.
◊ The BIMATIK heat output regulator is defective.
◊ The chimney draught is inadequate.
The unit cannot be regulated.
◊ The BIMATIK heat output regulator is defective.
◊ The filling flap 1 or furnace door is not shut.
◊ The chimney draught is too strong or inadequate.
The unit is not transporting any warm air.
◊ The unit is not being supplied with power.
◊ The fan thermostat is defective.
◊ The circulating air fan is defective.
◊ The blow-out grille is closed.
◊ The air suction inlets are blocked.
◊ There is no fuel in the unit.
The fire is out.
If any failure occurs though which cannot be eliminated
by the operating person, please contact your dealer or
contact person.
Removing Ashes.
Clean the fire grate once or twice a day with the pokers
supplied and remove all cinders, ashes and other combustion residue.
Empty the ashpan when necessary but at least once a
day. The ashpan may only be filled up to the upper
edge. Make absolutely sure that the ash cone never
reaches the lower edge of the grate because this can
cause damage.
Replace the empty ashpan as quickly as possible and
close the front door to prevent an external draught.
Cleaning.
The furnace and the attached flue gas chimneys must
be cleaned on a regular basis depending on heating operation. Soot or flying ash deposits negatively affect
heating performance.
The collection box and the flue gas chimneys can be accessed once the plate for the warm air cover (item 1)
and the cleaning opening (item 22) have been disassembled. The flue gas chimneys and the collection box
must be cleaned with an appropriate brush. Before assembling the warm air cover, the gasket (item 21) must
be checked and replaced if necessary.
In addition to daily maintenance, we recommend a thorough cleaning and maintenance of the entire unit after
each heating period. Any damaged parts must be replaced to prevent more serious damage from occurring.
