GENERAL
Praasu is versatile outdoor fireplace / barbeque / cook-top. It can be fired with wood and/or charcoal.
Praasu may be used as wood-burning cooker, large frying surface and/or as barbeque. In addition,
Praasu works as open fire place when opening the lid part of the frying surface. Praasu is long life
product for private and professional use.
CAUTIONS
Read manual carefully before using Praasu for the first time. Keep this manual for later reference.
Praasu is for outdoor use only!
Incorrect use may result harm to others and to the environment. The frying pan's surface becomes hot
during use, keep the children and pets away from the hot appliance. Do not move Praasu during use.
Any constructional or other changes made to the Praasu by user may cause a hazard and will void the

TECHNICAL INFORMATION OF THE PARTS
FURNACE
•The heart of the product, the furnace, is designed to enable efficiency, pure combustion and
long life time of the furnace. After ignition of wood, Praasu is ready for cooking in a few
minutes.
•The material of the furnace is stainless steel enabling long life time and high utilization rate.
•The furnace has double wall construction which has two main functions:
1. Environment. Primary air is conducted to the furnace through the ash box and secondary
air at top of the flames through the double wall construction. The system enables more
pure combustion of the fire wood. The pure combustion reduces emissions of fine particles
(<2,5µm), black carbon, PAH (polycyclic aromatic hydrocarbons) compounds and carbon
monoxide which are all due to the incomplete burning of the wood.
2. Safety. Double wall furnace restricts the conduction of the heat from the furnace to the
exterior wall cover.
EXTERIOR COVER
•Exterior cover is made of stainless steel, and coated with pine
texture heat resistant black (RAL9005) paint. Picture.
•The textured surface reduces surface heat conductivity.
FRYING SURFACE, GRATE AND SMOKE DUCT
•The frying surface material is 6 mm thick carbon steel. The thick frying surface has high heat
content which slows temperature changes down of the surface. The mid part, above the
furnace is the hottest part of the frying surface, together with smooth frying surface food can
be seared efficiently. The temperature on the sides is lower and suits well for cooking the food.
•The mid part of the frying surface can be opened from the side of the Praasu with the crank
delivered with the product. When opening the surface, Praasu can be used as open fire device.
•The cast iron grates are delivered with Praasu. By opening the lid (part of the frying surface)
with the crank, the grates can be installed on the aperture of the frying surface. By barbequing
on the grates, food get nice striped searing marks and the original flavour of the wood grilling.
•The duct is manufactured of stainless steel.

INSTALLATION
Install Praasu on the non-flammable and solid floor or ground. For the floor, non-flammable surface
must extend over 800 mm from the bottom edges in all sides. At the bottom of Praasu, there are
adjustable legs. Adjust Praasu straight so that frying surface is exactly horizontally on all directions.
All the packaging materials must be removed carefully. Remove also thin protective film from stainless
steel smoke duct before use. This protective film should also be removed in case the duct is exposed to
sunlight. Sunlight can damage the film making it hard to remove.
Safety distance to the flammable vertical surfaces under the frying surface level is 500 mm, but in the
side of furnace door 800 mm.
Above the frying surface safety distances must sufficient, because Praasu is open fire device. From the
smoke funnel or directly from the fire when lid is open, flaming sparks may be wafted in the air.
Make sure that Praasu is not directly under or close to the roof, eaves or under or close to any other
flammable construction or material. Installing place of Praasu must be chosen so that open fire will not
cause danger to the surrounding settings. The user of Praasu is responsible to follow local laws and
regulations related to open fire. Please consult your local authorities in case of uncertainty of the local
regulations related to open fire.
FIREWOOD/CHARCOAL
To ensure efficiency and environmental friendliness, use dry firewood. The optimal firewood
dimension for cooking and barbequing with Praasu is, crosscut diameter about 4-5 cm and length
about 35 cm. Typical high heat content firewood species are oak, birch, ash, beech, maple, apple and
hickory. Other species may be used also, but limit the use of redwood (scots pine) due to the high
content of resin.
Never burn in Praasu anything else than designated firewood and/or charcoal. Impregnated, coated,
glued or chemically treated timber may release poisonous gases when burning.
SETTING PRAASU ON OPERATION
Check the ash box first and empty it if needed. Open the aperture of the frying surface with the cramp
delivered with Praasu. Load the furnace with the firewood through the furnace door. Arrange 3-4
pieces of wood slightly crosswise, if possible, to ensure free flow of the air from the bottom of the
furnace. Praasu gets the primary air from the bottom of the furnace, through the ash box. Use fire
starter and set the fire on the top of the firewood pile. By starting fire on top of the pile, the
combustion is as pure as possible.
If firewood dimensions are bigger or smaller than recommended, adjust the amount of the firewood
accordingly recommendation to achieve the suitable temperature for barbequing and cooking.

In case of cooking or frying, close the aperture with the cramp when the fire is properly lit. In case of
barbequing, install grates on the aperture on the cook top. The Praasu is ready for barbequing when
visible flames are gone and firewood glows in orange-red colour.
In case Praasu is used as fire pit, the firewood can be piled vertically thought the
aperture on the frying surface, see the picture on the right.
In case also charcoal is used, add moderately charcoal on top of the glowing fire
when visible flames are gone. The charcoal can be added through the aperture
on the frying surface.
Before cooking, brush the frying surface and grates with the cooking oil or grease.
BARBEQUING
Before cooking, brush the frying surface and grates with the cooking oil or grease.
The hottest area of the frying surface is at the top of the furnace. The hottest area suits for searing the
surface of the food quickly and for barbequing food which requires short barbequing time such as fish,
shellfish and medium steak.
In case direct fire is needed, open the lid with the cramp and install grates delivered with Praasu on
the aperture on the frying surface.
The sides of the frying surface have a lower temperature, making it ideal for cooking meat slower
through.
After cooking, remove grates and close the lid. Then clean the frying surface with sharp edge spatula
to prevent mould growth on the frying surface due to the food & fat remains.
TEMPERATURE ZONES OF FRYING SURFACE
Temperature of the frying surface
increases rapidly after igniting the
firewood. The surface temperature of the
hottest area (area in red in the picture)
increases during the most intense flames
for over 450 degrees C briefly and in the
middle of the left side up to 300 C by four
pieces of dry birch firewood. When the
visible flames are gone and the wood
solids are glowing, the frying surface
temperatures at the hottest area are
about 340 C, left center area about 260 C,
right center, and around the edges of the
frying surface are about 170 C.
The proper cooking temperature can be maintained by adding one piece of firewood at a time when
the charcoal burn is diminishing.
Picture 1. The temperature zones of the frying surface,
the hottest area is in red and the coolest in yellow.

MAINTAINING PRAASU
Empty the ash box frequently. The full ash box impairs the air flow to the furnace causing incomplete
combustion. Imperfect combustions cause more carbon black(soot), PAH and carbon monoxide
emissions.
Cover Praasu when it is cooled down with the protective hood. Hood prevents water accumulation
inside the Praasu, prevents corrosion of the frying surface and prolongs the lifetime of the black
textured paint.
In case, painted surface is scratched or damaged, it is recommended to repair paint the damaged area
with Teknoheat 500 paint, colour RAL9005. The exterior cover of Praasu is stainless steel and lasts
sufficiently in outdoor conditions, but non-repaired paint film may be peeled off slowly if not
corrected.
Clean Praasu when needed. Stainless steel and painted surfaces are recommended to clean with
slightly alkaline soap-water solution. Leave soap solution on the surfaces for 15 minutes before
scrubbing dirt down with soft cloth or sponge. It is not recommended to use abrasive detergents or
cleaning tools as they may leave grinding pattern marks on the stainless-steel surface.
Finish cleaning by drying surfaces with soft cloth.
