The owner of small firing systems or the person authorised for the small firing system is to keep the technical documentation and is to submit it to the authorities or the chimney sweep on request.
Note
Please observe the national and European standards as well as local regulations concerning the installation and operation of firing installations!
Packaging
Your first impression is important to us! The packaging of your new stove provides excellent protection against damage.
However damage to the stove and accessories may still occur during transport.
Note
Therefore please check your stove on receipt for damage and completeness! Report any deficiencies to your dealer immediately! Pay particular attention during unpacking that the stone panels remain intact. Scratches to the material can easily occur. Stone panels are excluded from the warrant.
The packaging of your new stove is environmentally neutral to a great extent.
Tip
The wood used in the packaging has not been surface treated and may therefore be burnt in your woodburning stove (not in pellet stoves!). The cardboard and film (PE) can be depolluted via the municipal waste collection for recycling.
Electrical connection
The stove is supplied with an approx. 2m long connecting cable with a Euro­plug. This cable is to be connected to a 230Volt/50Hz socket. The average electrical power consumption is about 20 Watt in heating operation and approx. 150 Watt during automatic ignition. The connection cable must be laid in a way that there is no contact to any sharp edges or hot surfaces of the stove.

2. IMPORTANT INFORMATION
General warning and safety information
Observance of the introductory general warning information is imperative.
Q Read the entire manual thoroughly before installing and putting the stove into
service. Observe the national provisions and laws as well as the regulations and rules applicable locally.
Q RIKA stoves should only be installed in rooms with normal humidity (dry
areas according to VDE 0100 Part 200). The furnaces are not splash water protected and may not be installed in wet areas.
Q Only approved transport equipment with sufficient load carrying capacity
may be used with your heating appliance.
Q Your heating appliance is not suitable for use as a ladder or stationary
scaffolding.
Q The burning of fuel releases heat energy that lead to extensive heating of
the stove surfaces, doors, door and operating handles, glass, flue pipes and possibly the front wall. Refrain from touching these parts without appropriate protective clothing or equipment e.g. heat-resistant gloves or means of operation (operating handle).
Q Make your children aware of this particular danger and keep them away from
the stove during heating.
Q Only burn approved heating materials.
Q The combustion or introduction of highly flammable or explosive materials
such as empty spray cans etc. in the combustion chamber and storing them near the stove is strictly prohibited due to the danger of explosion.
Q No light or inflammable clothing is to be worn when post-heating.
Q Use the heat-resistant gloves supplied to open the doors of your stove.
Q Make sure that no embers fall out of the combustion chamber onto
inflammable material.
Q Placing non-heat resistant objects on the stove or near it is prohibited.
Q Do not place clothing on the stove to dry.
Q Laundry racks etc. must be placed at a sufficient distance to the stove –
ACUTE DANGER OF FIRE!
Q When your stove is burning, the use of highly inflammable and explosive
materials in the same or adjacent rooms is prohibited.
Q Pellet stoves are generally designed and developed to operate as an
additional heat source (supplementary heating). The cleaning, as well as the information about the wear are set accordingly in our manual. If the stove is heated in continuous operation, the cleaning intervals are shorter. Increased wear, especially of the thermally stressed parts, is the result. Please therefore strictly follow the requirements for cleaning and maintenance!
Note
Waste and liquids may not be burnt in the stove!
Note
To prevent your stove from overheating of the internal components, do never cover the convection fins!
Note CAUTION when filling the pellet container. The opening of the pellet container is sufficiently dimensioned to ensure easy filling. Take great care that no pellets drop to the convection fins and the hot stove body. This can cause a lot of smoke.
Tip
Therefore we recommend refilling the pellet container at a cold stove.
Note
Your stove will expand and contract during the heating and cooling phase. This can sometimes lead to slight bending or cracking noises. This is normal and is no reason for a complaint.
First heating
The stove body, just as various steel parts, cast iron parts and the flue pipes are painted with a heat resistant paint. During the first heating the paint dries out completely. This may cause a slight smell. Touching or cleaning the painted surfaces during the curing should be avoided. The hardening of the paint is finished after the first heating with high power.
Safety distances
Note
1. To non-combustible objects a > 40 cm b > 10 cm
2. To combustible objects and reinforced concrete load-bearing walls a > 80 cm b > 10 cm
Tip
please observe a minimum distance of 20 cm behind and sideways the stove for maintenance.

Prior to set up
Floor bearing capacity
Ensure that the substructure is capable of bearing the weight of the stove prior to set-up.
Note
No modifications may be made to the firing installation. This also leads to loss of warranty and guarantee.
Floor protection
A base is recommended (glass, sheet steel or ceramic) if the floor is combustible (wood, carpet, etc.). Please observe the respective local regulations and rules.
Flue pipe connection
Q Flue pipes pose a particular source of hazard regarding gas leaks and
fire. Get the advice of an authorised specialist company for the layout and assembly.
Q Please observe the corresponding installation guidelines for walls panelled
with wood when connecting your flue pipes to the stove.
Q Observe the formation of flue gas (atmospheric inversion) and draughts
when the weather is unfavourable.
Q Infeed of too little combustion air can lead to smoke in the rooms or to flue
gas leaks. Hazardous deposits in the stove and chimney may also occur.
Q If flue gas escapes, let the fire burn out and check whether all the air inlet
openings are free and the flue gas pipes and the stove pipe are clean. If in doubt notify the master chimney sweep since draught malfunctions may be connected to your chimney.
The correct chimney connection
There are several ways to connect your stove to the chimney, eg:
*1
*2
*3
*1
*2
*3
1) wind break, 2) chimney, 3) inspection opening
For the selection of the connection and to ensure a proper connection between the stove and chimney, please read the guide „INSTALLING THE STOVE“ or ask your local chimney sweep.
Stoves type 1 (BA 1):
Q Suitable for multiple occupancy. (Note the different country regulations.)
Q These may only be operated with the combustion chamber door closed.
Q The combustion chamber door is to be kept closed when the stove is not
in operation.
Q Fouling of the chimney i.e. deposits of highly inflammable materials such as
soot and tar and subsequently fire in the chimney may occur if the chimney is miscalculated and dimensioned wrong.
Q If this occurs, disconnect the mains plug. Phone the fire brigade and get
yourself and other residents out of harm’s way.
Note
Your pellet stove can be operated room air dependent or room air independent.
ROOM-AIR INDEPENDENT OPERATION: The stove is certificated for type FC52x of the approval principles for the inspection and evaluation of ambient air independent fireplaces specified by the Deutsches Institut für Bautechnik (DIBT) (German Institute for Building Technology). Thanks to an air-tight configuration of the air supply line and flue pipes the stove may be operated in air-tight rooms and in rooms with room-air installations (e.g. controlled ventilation and venting systems, extractors etc.).
ROOM-AIR DEPENDENT OPERATION: In combination with room-air installations (e.g. controlled ventilation and venting systems (extractors etc.) it must be ensured that the stove and the room air system are monitored and safeguarded mutually (e.g. via a differential pressure controller). The combustion air infeed of approx. 20 m3/h must be ensured.
Please observe the respective local regulations and rules in consultation with your master chimney sweep. For changes after the printing of this manual, we can not assume any liability. We reserve the right to change without notice.

3. BRIEF INFORMATION ON FUEL - PELLETS
What are pellets?
Wood pellets are a standardised fuel. Every manufacturer must adhere to certain conditions in order to enable flawless, energy-efficient heating. Pellets are made from wooden waste, from sawmills and planning workshops, as well as from residue from forestry operations. These “starting products” are crushed, dried, and pressed into Pellet “Fuel” without any bonding agent.
ENplus – Pellets
This new pellets are a standard sets new benchmarks in the European pellet market. The traceability of pellets is ensured thanks to the use of identification numbers. The pellet manufacturers’ production facilities and manufacturing processes are reviewed every year. A quality assurance system ensures the pellets comply with the requirements of the new standard and that the conditions for trouble-free heating are guaranteed

Your pellet stove is only approved for the burning of pellets of tested quality. Please ask your pellet stove dealer for tested fuel and a list of monitored fuel manufacturers.
Note
Only burn pellets that have been inspected according to ÖNORM, DIN Plus or ENplus-A1. Using poor quality or prohibited pellet fuel will have a negative effect on the function of your pellet stove and can also lead to the warranty becoming null and void, as well as the product liability connected with this.
Note
Burning straw, maize, woodchips etc. is not permitted! Observe waste incineration legislation! Non-observance of these regulations makes void all warranty and guarantee claims and may impair the safety of the unit!
Pellet container refilling during operation
Note
CAUTION when filling! Avoid direct contact between the plastic bag and the hot stove. Immediately remove all pellets that have fallen on the hot stove or next to the container!
We recommend always having a suitable amount of pellets in the container to prevent the fire from extinguishing due to a lack of fuel. Check the level frequently. However the container lid should be kept closed, except during filling.
If you refill the container during operation (open the container lid), the fan will speed up and the pellet auger will stop; operation will only be continued once the container lid is closed again (see WARNING AND ERROR MESSAGES)
Pellet container capacity (see Technical Data).
Pellet storage
In order to guarantee problem free burning of the wooden pellets, it is imperative necessary to store the fuel as dry as possible and free from impurities.
Pellets should not be kept in sacks outdoors or stored in a manner where they are exposed to the environment. This can lead to blockages in the screw conveyor.
Note
“Screw stoppers” are excluded from the warranty.

4. TECHNOLOGY AND SAFETY FUNCTIONS
The technological advances in your new combi stove are the result of years of testing and practical experience. The practical advantages of your pellet stove are convincing:
Operating comfort
The microprocessor-controlled combustion regulation optimises the interaction of flue gas blower and screw using the current combustion chamber temperature. This guarantees optimum combustion and operating status.
All function can be regulated centrally using the integrated operating unit. The intuitive graphic interface permits easy operation; all the settings can be made quickly and simply.
Top efficiency - lowest emissions
A very great heat exchange surface together with optimum combustion air control leads to excellent fuel utilisation.
Fine continuous pellet dosing in an optimised burner pot made of high-quality grey cast iron leads to virtually complete combustion with very good exhaust gas values - and this is guaranteed in every operating phase.
Note
The automatic control system means that during operation, the flame noise, pellets dropping and actuation of the electronic components permissible for living spaces are audible.
Pressure monitoring
The negative pressure in the combustion chamber is continuously monitored during operation. Below a defined threshold, a correct operation can not be guaranteed and the unit will switch off with the fault message „NOT ENOUGH LOW PRESSURE“ for safety reason.
Note
After the occurrence of the error message, maintenance or cleaning work necessarily has to be carried out! If the error occurs again, a safe operation is no longer guaranteed, the service must be informed immediately.
Note
If the stove is used in a room together with a kitchen hood it might happen that the built-in pressure switch stops the stove. If using the hood make sure make sure that an adequate supply of air is ensured.
Low-temperature shutdown
The unit switches off if the stove cools below a minimum temperature. This switch-off may occur if pellet ignition is delayed.
Electrical excess current protection
The stove has a main fuse (at the rear) to protect against excess current
Automatic cleaning cycle
The speed of the flue gas fan is increased every hour for a short period to blow ash from the burn pot, increasing the operational safety. The status indicator CLEANING appears on the display.
Only for stoves with turning grids:
Every 6 hours (interval adjustable) an additionally automatic cleaning cycle is performed. The stove stops, the automatic cleaning tilts the grid and then re-ignites the stove. The status indicator CLEANING appears on the display continuously. The cleaning procedure with tilting the grid is to convey ash and clinker from the burn pot into the ash drawer. This additional function does not replace a manual cleaning as described in CLEANING and MAINTENANCE, as this is absolutely necessary to do regularly.
Component monitoring
All the electrical components used are continuously monitored during operation. If a component is defective or can no longer be actuated correctly, then operation is stopped and a warning or error message is issued (see WARNING AND ERROR MESSAGES).
Auger motor monitoring
Too long or wet pellets as well as pellets with too high dust content (see BRIEF INFORMATION ON FUEL PELLETS) can cause so-called “auger jammers” in the auger channel. This may also happen if the pellets accumulate in the burn pot and the backlog reaches into the chute. The auger motor reacts in both cases with an increased current consumption, which causes the error message: DISCHARGE MOTOR BLOCKED. The stove will be stopped. Please call the customer service immediately.
Power failure (during heating)
After a brief power failure, the operating functions that were set before the power failure, continues. If the power failure lasts longer, the stove goes to start phase if sufficient temperature or embers are present. If the power failure lasts too long, the stove goes into the stop phase. The flue gas fan continues to burn any pellet residues (approximately 10 minutes). Then it will restart automatically.
Power failure (during the initial stage)
After a brief power failure the boot process continues. If the power failure lasts longer, the stove is in the stop phase. The flue gas fan continues to burn any pellet residues (approximately 10 minutes). Then it will restart automatically.

5. INSTALLING THE STOVE
General information
Note
Only use heat-resistant sealing materials as well as corresponding sealing strips, heat-resistant silicon and rock wool.
Note
Assembly may only be performed by authorised specialist companies.
Note
Also take care that the flue does not project into the free cross-section of the chimney.
Note
Please observe the regional safety and building regulations. Please contact your master chimney sweep in this context.
Note
Your stove is intended for room-air independent operation. Thus the stove pipe connections must be tightly sealed permanently for this use. Use a heat­proof silicon to position the stove pipe on the conical supports of the flue tube nozzles and for insertion in the chimney flue lining.
Note
The stove should not be pushed on unprotected floors.
Tip
Strong corrugated cardboard, cardboard or e.g. old carpet is useful to assist assembly and as a base. The stove can also be pushed on this cardboard or carpet.
We recommend original flue pipes from RIKA for proper connection.
Connection to the chimney
Q The device must be connected to an approved chimney for solid fuels.
The chimney must have a diameter of min. 100mm for pellet stoves and 130mm -150mm for log wood stoves depending on the diameter of the flue pipes.
Q Avoid long flue pipes to the chimney. The horizontal length of the flue pipe
should not exceed 1.5 m.
Q Avoid to many bends of the flue gas pipes. There should not be more than
3 bends in the exhaust pipe.
Q If you just can not connect directly to the chimney, please use a connection
with a cleaning opening.
Q Connections must be made of metal and must meet the requirements of the
standard (install the connections airtight).
Q Before installing a chimney calculation must be made. The evidence must be
performed for single occupancy to EN13384-1 and EN13384-2 for multiple occupancy.
Q The maximum draft of the chimney should not exceed 15Pa.
Q The derivation of the flue gases must be guaranteed even during a temporary
power outage.
Note
If connecting to multiple connection chimneys additional safety equipment is required. Your local chimney sweep will advise you in this case.
Connecting to a steel chimney
The connection must be calculated and shown with EN13384-1 and EN13384-2.
Use only insulated (double) stainless steel tubes (flexible aluminum or steel tubes are not permitted).
An inspection door for regular inspection and cleaning must be present. The flue pipe connection to the chimney has to be air-tight.
Combustion air
Every combustion process requires oxygen from the surrounding air. This so­called combustion air is removed from the living are in the case of individual stoves without external air connections.
This air removed must be replaced in the living space. Very tightly sealed windows and doors in modern flats may mean that too little air replaces that used. The situation also becomes problematical due to additional venting in flats (e.g. in the kitchen or WC). If you cannot feed in external combustion air, then air the room several times a day to prevent negativce pressure in the room or poor combustion.
Note
Please note that problems may arise due to updrafts in the case of combustion air supply from an integrated chimney ventilation shaft. If the combustion air flowing downwards is heated it may rise and thus counter the chimney with a resistance which in turn reduces the negative pressure in the combustion chamber. The chimney manufacturer is to guarantee that the resistance for the combustion air is a maximum 2 Pa even in the least favourable operating state of the chimney.
Feeding in external combustion air
only for devices which are able to run in room-air independent operation.
Q Combustion air must be fed to the stove from outside via a sealed pipe
for operation independent of the room air. According to EnEV, it must be possible to shut off the combustion air pipe. The open/closed setting must be clearly recognisable.
Q Cut the perforated rear wall out with a hacksaw.
Q Connect at the air intake either a pipe Ø125mm (log wood and combi
stoves) or Ø50mm (pellet stoves) and fix it with a hose clamp (not included!). At pellet stoves with longer intake pipes than 1m the diameter should be increased to 100mm. (see RIKA range).
Q To ensure sufficient air intake, the intake pipe should not exceed max. 4m
and have max. 3 bends.
Q If the line leads outside it must have a windbreak.
Q In extreme cold pay attention to icing on the air intake opening (check).
Q It is also possible to suction in combustion air directly from another
sufficiently vented room (e.g. cellar).
Q The combustion air pipe must be tightly connected (adhesive or cement)
permanently to the air nozzles of the stove.
Q If you do not use the stove for a long time, please close the combustion air
intake to prevent the stove from moisture.
If one or more of these conditions does NOT apply, the result is poor combustion in the stove and negative pressure in the installation room.

This option permits control of your stove via room temperature. You can set both the room temperature and the heating times required. A room temperature selected by you is observed during the heating times.
Please see the operating instructions for the option RIKA room sensor and wireless room sensor for more detailed information.
RIKA GSM Control
Your stove can also be controlled via a mobile phone as an additional option. Please see the operating instructions for the telephone option – GSM for more
detailed information.
RIKA interface for various options
for various options
The RIKA ROOM SENSOR, the RIKA WIRELESS ROOM SENSOR and the RIKA PHONE OPTION – GSM are to be connected to the interface (stove rear) using the connection cable supplied.
External room thermostat
Your stove has an interface on the rear wall to which you can connect a customary room thermostat. This requires a 2-pole cable of 0.5 – 0.75 mm² cross-section that you have to connect instead of the cable bridge fitted for delivery
External connection cable bridge
(condition as delivered)
If the control of your stove is to be assumed by an external room thermostat, you have to connect your external room thermostat (1) instead of the standard integrated cable bridge (2).
The connected room thermostat can be operated in either MANUAL or AUTOMATIC MODE. In both MODES, the current set heat output is used, in AUTOMATIC MODE the heating times set at the stove can also be activated.
You can see whether the external demand is currently activated in the INFO main menu in submenu item Info - inputs.
If your stove receives an external demand to stop operation, it takes approx. 5 minutes until it switches off. All further settings required to your thermostat can be taken from the respective room thermostat operating instructions.
Note
Operation is not possible unless either a cable bridge or an external room thermostat is connected. The external demand has priority over all operating modes (MANUAL/AUTOMATIC/COMFORT).
Option RIKA firenet
Only for combination and pellet stoves with touch panel version V2.16 or higher.
The RIKA firenet module connects your stove to the Internet. You can operate the stove with any Internet-enabled device (tablet, PC, Smartphone ...). So you retrieve the operational status, various information and make your settings remotely.
For further information, please contact your RIKA dealer.

8. CLEANING AND MAINTENANCE
Basic information
Note
Ensure that you do not vacuum into the combustion air line during heating operation during any cleaning (vacuuming). You could vacuum out embers – FIRE RISK!
Note
SERVICE appears on the display after consumption of 700 kg pellets. Cleaning and maintenance is to be performed. This message can be acknowledged by pressing ENTER and operation can be continued. The number of SERVICE messages is stored in the background.
Note
Your stove must be switched off and cooled before any maintenance work is performed. Only work on the unit when the mains plug has been disconnected.
The frequency with which the stove requires cleaning and the maintenance intervals depend on the fuel you use. High moisture content, ash, dust and chips may more than double the maintenance required. We would like to again point out that only tested and recommended pellets or logs may be used as fuel.
Tip
Wood as fertiliser - the mineral content of the wood remains in the combustion chamber as ash as a residue of the combustion. This is an excellent fertiliser for all plants in the garden; it is a completely natural product. The ash should be stored first and slaked with water.
Note
Ash may contain embers – only place ash in sheet steel containers!
Open the combustion chamber door
To open or close the combustion chamber door and the ash-chamber door use the included key. This key can be stored on the back of the stove when not in use.
Cleaning the fire trough
Despite the automatic ash dumping prior to and during heating operation, care should be taken that the air intake openings are not blocked with ash or clinker. Remove the clinker using the brush supplied and vacuum out the fire trough.
Do not damage the ignition when cleaning with the brush.
Note
Clean the fire trough regularly. Only clean when cold, when embers are extinguished!
Note
If the stove is heated in continous operation, it must be cleaned 2x within 24 hours. FIRE HAZARD!
Cleaning the flame temperature sensor
Remove the dust deposits from the sensor at regular intervals. Use a clean cleaning cloth or newspaper.
Empty the ash drawer
Empty the ash drawer regularly. The ash drawer is simply pulled forward with the ash-chamber door open.
Cleaning the door glass
The viewing window becomes coated in the case of solid fuels, particularly with the very fine ash of wood pellets, light or dark depending on the pellet quality (especially with low output). The glass can be cleaned best with a moist cloth. Stubborn dirt can be removed with a special cleaner available from your stove dealer. Usual cleaners containing acid or solvents can be too harsh and damage the glass.
Cleaning painted surfaces
Wipe of the painted surfaces with a damp cloth, do not scrub. Do not use solvent-containing cleaners.
Page 18
Cleaning flue gas paths
The flue pipes should be cleaned at least 2 x a year or after approx. 700 kg pellets. The flues are behind the combustion chamber.
Open the decorative glass door by pushing the button on the display before you unplug the stove from the power supply.
To remove the convection fins turn the 4 screws (marked) clockwise, the lid lifts off. Then carefully remove the convection fins up.
Now remove the two hex screws on the side panel and lift the side panel.
Loosen the 4 allen screws and remove the combustion chamber lid. Remove the two hex screws and the side cleaning lid.
Now clean the flues with the supplied brush. Vacuum the combustion residues with a vacuum cleaner.
Loosen the two hex screws under the ash door and open the outer cleaning lid.
Vacuum-clean the combustion residues off the flue gas collecting duct, especially the areas to the side flues.
Open the two wing nuts of the rear cleaning lid.
Vacuum the combustion residues from the flue gas collecting duct in the rear side.
Install the removed parts in reverse order again. Make sure before mounting the convection fins that the 4 screws (marked in
green) are flush.
Then carefully place the convection fins in the supposed recess and press down firmly with your hand until the cover locks into place.
Note
Your stove may suck in false air via incorrectly sealed cleaning covers; this air may lead to incomplete combustion in the fire trough and thus piling up of pellets - FIRE HAZARD! To ensure the proper operation of your pellet stove, replace the defect (porous, frayed) seals after cleaning and maintenance.

Cleaning the convection air openings
Vacuum clean any dust deposits from the convection air openings at regular intervals.
The stove should be cleaned thoroughly prior to the start of the heating season to prevent excess odour.
Combustion air - intake
If necessary, please also clean the air intake with a hoover.
Note
Only when the stove is cold! You could vacuum out embers – FIRE RISK!
Cleaning the pellet container
Do not refill the completely empty container immediately; remove the residues (dust, chippings etc.) from the empty container. The unit must be disconnected from the mains!
Cleaning the flue gas channels
annually Remove the flue pipes. Inspect and clean chimney connection. Brush off any
soot and dust deposits in the fire and in the flue pipes and vacuum.
Note
Accumulated fly ash in the flue gas channels may impair the performance of the stove and pose a safety risk.
Checking door seal
annually The condition of the seals at doors and glass should be checked at least 1 x per
year. Repair or replace seals depending on condition.
Note
Only intact seals ensure your stove works perfectly.
Bearings
annually All built in bearings (pellet screw, turning grid) should be checked. Clean or
replace bearings depending on condition.

10. INSTRUCTIONS FOR COMMISSIONING PROTOCOL
FOR PELLET AND COMBI STOVES
The commissioning protocol is to be treated as a documents and serves as the basis for the warranty and guarantee terms. It is to be completed entirely, in particular the stove data and addresses, the work to be performed is to be ticked off after completion. The signatories confirm with their signatures that all the items on the list have been concluded properly.
Note
Please return 1 completed protocol for putting into service to RIKA Innovative Ofentechnik GmbH, Müllerviertel 20, 4563 Micheldorf, Austria.
Electrical periphery
It is important that the connection socket in the electrical periphery is earthed. The operability of any room thermostat present must be checked. The execution of commands is to be established by phoning in the case of a GSM modem.
Exhaust gas system
The exhaust line, stove and combustion air inlet are part of the combustion system as a whole; therefore the correct execution must also be checked. The plug connections should be tight in general since the system works with excess pressure. The exhaust tube has a diameter of 100mm for pellet stove, and of 150 mm for the combi stove, which is sufficient for short distances. In the case of several changes in direction, the resistance of the exhaust system can increase with the flue to such an extent that the combustion quality suffers and/or noise arises from the greater flow speed. Correct determination of the chimney draught can only be performed at nominal thermal output and serves to evaluate the chimney. If the draught is more than 15 Pa, then a draught limiter should be installed.
Stove functions
These are the basic stove functions that are to be checked and ticked off. The stove is ready for operation if these functions are ensured.
Operator instruction
This is one of the most important points in the putting into operation. It is very important that the operator understands the stove properly and is prepared to assume responsibility for the basic tasks required for operational safety.
In particular the connection between special features of a biomass heating system and his obligations as well as the warranty and guarantee terms must be explained. e.g. non-tested pellets and screw blockers, lack of cleaning or maintenance and stove malfunctions. Thorough instruction can prevent many complaints.
Stove functions
Explanation of the processes in the stove during ignition, normal operation, cleaning phase etc.
Control
Explain operator’s possibilities to intervene, empty pellet container, room thermostat, GSM modem, functions and settings, program times if necessary. Operating instructions: Handover and reference to the content to the following points, is a document.
Warranty terms
Difference between warranty (statutory) and guarantee (voluntary), terms of guarantee, determination of wearing parts, reference to pellet quality to be used and the consequences of poor quality.
Cleaning instructions
Ash and dust occurs with a biomass heating unit. The fire trough is to be cleaned regularly with regular heating operation (in the case of pellet operation, the drilled air holes in particular must be free of residues). The ash drawer is to be emptied regularly. The flue gas pipes are to be cleaned once or twice in the heating season depending on stove type; by a specialist company is best.
Maintenance
Maintenance work after defined burn-off output is to be performed by specialist company, including thorough cleaning.
Combustion
All doors must close tightly to prevent intake of false air.
