1. Installation Instruction
▪The heater has been designed to allow simple connection to an existing chimney by a single connecting piece. The
connecting piece must be as short and straight as possible, in a horizontal position or slightly inclined. The piece must
be tight.
▪Be sure that all local regulations, including those concerning both national and European standards on construction and
fire prevention, are respected during installation. Inform the competent inspector prior to installation. Be sure that
combustion air supply is sufficient; particularly in rooms where windows and doors are closed tight.
▪Chimney properties shall be calculated in accordance with applicable standards with the three values stated in this
manual (16.).
▪The heater must stand on a hearth with adequate bearing capacity. If bearing capacity is too low, adequate measures
must be taken (e.g. a board must be laid to split weight).
2. General Safety Instructions
▪Fuel combustion emits calorific energy that heats the surface of the heater, combustion chamber door, door and control
elements handles, safety glass, flue pipes, and eventually also the front of the heater. Do never touch those parts without
adequate safety wear or elements (fireproof gloves etc.).
▪Warn children of such danger and make sure they do not stay close to heater when in operation.
3. Acceptable Fuel
▪Fuels acceptable for burning include wood logs of up to 17 cm in length and 8 cm in average, and lignite briquettes.
▪Make sure that only air-dried wood logs are used. Burning of waste, and plastics in particular, is forbidden by law on
emissions. Besides, such fuel may cause damage to the fire place and chimney and subsequently may injure health
and smell may annoy your neighbours. Air dried wood logs with 20% maximum humidity may be obtained after at least
one year (soft wood) or two years (hard wood) of drying.
▪Wood is not slow combustion fuel and thus, continuous heating throughout the night is not possible when burning wood.
▪Liquid fuel is unacceptable.
4. Firing
▪During the first firing bad smell due to drying of protection paint is inevitable but the smell shall fade quickly. Make sure
the room with the heater is well aerated when firing. Quick firing is essential because incorrect procedure may cause
increased emissions.
▪When lighting the stove, the primary air slider must be fully open. It is advisable to light the fire with paper, wood chips
and smaller firewood.
▪Add more fuel as soon as firing fuel catches fire. Do never use alcohol, petrol or other flammable liquids for firing. Do
always use some paper, wood chips, and a small amount of fuel for that. Make sure that primary and secondary air is
supplied to heater when firing. Make sure that heater is under control during firing.
5. Operating More than One Fireplace
▪Make sure that combustion air supply is sufficient when operating more than one fireplace in one room or within the
same air system.
6. Transition Season Operation
▪When exterior temperature rise during transition season draught can decrease at low burning capacity and flue gas may
not be evacuated completely. In such case add only small quantities of fuel and open the slider of primary air supply so
that loaded fuel burns more quickly (flame) and draught gets steady. Ash needs to be raked carefully more often to
enhance air circulation below fireplace.
7. Cleaning and Checking
▪Heater flue pipes need to be checked for deposit and eventually swept at least once a year or more often, e.g. while
sweeping chimney. Make sure your chimney is swept regularly by a chimneysweep. The frequency of sweeping shall
be defined by competent inspector. Heater should be checked by an expert every year.
8. Versions
▪Heaters with spring fireplace door can be connected to a chimney with multiple taking for other heaters and fireplaces
provided that dimensions of the chimney are in compliance with applicable standards.
▪The door of the heater with spring fireplace door must always be closed during operation, except for firing, fuel charging,
and ash removing. Otherwise, operation of other equipment connected to the chimney may be affected or flue gas may
leak.
▪The heater is designed for intermittent operation.
9. Combustion Air
▪Since heaters are fireplaces depending on surrounding air and take combustion air from the room, adequate intake of
combustion air is vital.
▪In rooms with tight windows and doors (e.g., as energy-saving measure) fresh air intake may be low and thus affect
draught of the heater. Also, your well-being may be affected; even your safety may be threatened. It may sometimes be
necessary to assure adequate intake of fresh air e.g., by installing air shutter close to heater or by combustion air pipe
leading to exterior or to a well aerated room (except boiler room). In particular it is vital that combustion air pipes are

PISLA OY | Teollisuustie 6-8 | FI 44500 VIITASAARI | [phone] | www.pisla.fi
open during operation of fireplace. Steam flues located in the same room with fireplace may affect heater’s operation
(smoke may leak to inhabited room despite closed fireplace door) and therefore must never be operated parallelly with
heater.
10. Fire Protection
Distance from flammable structures and furniture
▪A minimum distance from combustible materials is required to ensure adequate thermal protection:
▪KORPI ECO ja KIPINÄ ECO: 40 cm at the back and 40 cm at the sides, 80 cm at the front and 150 cm at the top.
▪Minimum distances from flammable structures and furniture are stated on heater’s label and must be observed.
Heater
▪For solid fuel heaters floor in front of fireplace’s door made of flammable materials must be protected by a non-flammable
hearth. Its minimum dimensions are 40 cm (50 cm recommended) in the front and 10 cm on the sides of fireplace.
11. Spare Parts
▪Only spare parts approved or provided by the manufacturer may be used. For inquiries, please, contact a specialized vendor.
▪No modifications to heater are allowed!
12. Warning in case of fire in chimney
▪Deposit in chimney may catch fire if unsuitable or humid fuel is used. In such case close all heater air holes immediately and
call the fire brigade. After fire is extinguished chimney should be inspected by an expert for cracks or untight places.

We recommend the use of a T600-compliant flue connection pipe or pipe set. The connection to the pipe must always be made
in the room where the device is placed. Make sure that the connecting pipe is easily accessible for sooting and cleaning. The
joints must be detachable and insulating. Avoid too long a horizontal section before the flue. If this cannot be avoided, the rise
must be at least 5 cm/m.
17. Recycling and disposal
▪The fireplace and its packaging materials must be disposed of in accordance with local regulations for waste disposal
and recycling.
▪Package: The manufacturer recommends disposing the different parts of the packaging as follows: take the steel
stripe and the cardboard to a collecting point, wooden parts can be burnt.
▪Once the service life of the product has expired the manufacturer recommends disposing it at a collection point, and
the refractory-bricks and ceramic parts at a waste deposit.
