Nordpeis N-29P User Manual
IMPORTANT SAFETY PRECAUTIONS!
- Please follow the installation manual when connecting your stove / fireplace to the chimney / flue pipe. If connected differently from instructionplease, consider the heat radiation from the flue pipe to the surrounding materials.
- Before use, please carefully read the user manual and follow the instructions.
- Integrated or defined convection openings may never be reduced or partially obstructed. This may lead to overheating, which again can cause house fire or serious damage to the product.
- Use only designated fire starters. Never use gasoline, diesel or other liquids to start the fire. This may cause explosions!
- Never use other fuel than natural dry chopped wood. Briquettes, peat, coke, coal and waste from construction materials develops far higher temperatures and emissions than natural wood. Since your product has been designed for use with natural wood only, other fuels may damage the product, chimney and surrounding constructions.
- In case of damage to glass or door gasket, all use of the product must be discontinued until the damage has been repaired.
Failure to follow these precautions will leave your warranty void and expose people and property to danger.
Advise: Even if not required in your area, it is always wise to have a qualified stove / fireplace fitter do the installation, or at least the final inspection before use.
1. Prior to assembling the insert
All our products are tested according to the latest European requirements and also to the Norwegian standard NS 3058 and NS 3059, which include particletests. However, several European countries have local regulations for installation of fireplaces, which change regularly. It is the responsibility of the client that theseregulations are complied with in the country/region where the fireplace is installed. Nordpeis AS is not responsible for incorrect installation.
Important to check
(please note that this list is not exhaustive):
- distance from firebox to combustible/flammable materials
- insulation materials/requirements between fireplace surround and back wall
- size of floor plates in front of fireplace if required
- flue connection between firebox and chimney
- insulation requirements if flue passes through a flammable wall
- an access for cleaning the appliance, the flue gas connector, the chimney flue must be provided
Chimney draft
Compared with older models, the clean burning inserts of today put significantly higher demands on the chimney. Even the best insert will not work properlyif the chimney does not have the right dimensions or is not in good working order. The draught is mainly controlled by gas temperature, outside temperature, airsupply as well as the height and inner diameter of the chimney. The diameter of the chimney should never be less than that of the flue/chimney collar. For draftrequirements at nominal heat output, see technical table
The draught increases when:
- The chimney becomes warmer than the outside air
- The active length of the chimney over the hearth increases
- Good air supply to the combustion
It can be difficult to obtain the right draught conditions in case the chimney is too large relative to the insert, as the chimney does not heat up well enough. In suchcases you may want to contact professional for evaluation of possible measures. Draught that is too strong can be controlled with a damper. If necessary,contact a chimney sweeper.
Attention! Adverse flue draught or adverse weather conditions, e. g. mist, wind etc., may interfere the necessary flue draught. This should be checked before lightening the fireplace. If there is no necessary flue draught in the chimney, the use of the fireplace should be avoided.
Appliance can be connected to shared flue gas pipe sytem . In case of simultaneous operation with other heating appliances, there must be sufficient combustion air provided.Warning! In case of the appliance connected to shared flue gas pipe system – the Self Closing Door system must be operational.
Air supply (mm=AIR)
A set for fresh air supply is available as an accessory. This will ensure that the air supply to the combustion chamber is less affected by ventilation systems, kitchen fans and other factors which can create a down-draught in the room. In all new constructions, we strongly recommend the product is designed and prepared for direct supply of outside air. In older houses also, the use of fresh air supply set is also recommended. Insufficient air supply can cause poor draught and thereby low combustion efficiency and the problems this entails: soot stains on the glass, inefficient utilisation of the wood and a soot deposits in the chimney.
Warrning! Extractor fans when operating in the same room or space as the appliance may cause problem.
Warning: Keep the air intakes, supplying combustion and convection air free from blockage. If the requirements for ventilation areNOT complied with, the product can overheat. This can cause a fire.For your own safety, fully comply with the assembly instructions. All safety distances are minimum distances. Installation of the insert must comply with the current rulesand regulations of the country where the product is installed.Nordpeis AS is not responsible for wrongly assembled inserts. Subject to errors and changes. For the latest updated version of the manual go to www.nordpeis.com
2. Technical information
Inserts from Nordpeis all have secondary combustion and are clean burning. The combustion takes place in two phases: first the wood burns and then the gases from the fumes are lit by the heated air. This ensures that new inserts have minimal emissions of soot particles and un-burnt gases (such as CO) and are thus better for the environment. Clean burning inserts require a small amount of wood to obtain good heat output. Use exclusively clean and dry wood. We recommend seasoned hardwood with a maximummoisture content of 20%

Warning: If the requirements for ventilation areNOT complied with, the cooling airflow around the product will be considerably reduced and the product can overheat. This can cause a fire.
3. Safety distances
Firewall
Ensure that the minimum safety distances are fullfiled (FIG 1).When connecting a steel chimney to the top outlet use the security distances required by the manufacturer.
Important! When placing the insert on a combustible floor, a steel plate of at least 0.7mm must cover the entire floor surface inside the surround. Any flooring made of combustible material, such as linoleum, carpets etc. must be removed from underneath the steel plate.
The insert expands when in use, and for this reason the surround must NEVER rest on the insert, but have a gap of about 3 mm. The insert must neither rest on the bench plate or against the sides. It is recommended to dry stack the surround in order to adjust the insert prior to perforating the chimney for the flue connection.
4. Assembly
Removing the insert from the pallet FIG 2Before the insert is removed from the pallet, remove the accessories in the combustion chamber.
Attention! Our inserts are prepared for connectingthe smoke pipe on the outside of the flue collar Ø150
*Alternative versions of the flue collar exist due to National requirements. For the flue connection to the chimney, follow the recommendations from the chimneymanufacturer.
Operational control
When the insert is in upright position, and prior to mounting the surround, control that all functions are easy to maneuver and appear satisfactory.
The air vent control is turned to the right to increase the air supply. Normal working area is between the minimum setting and the noticable click pushing it right.Between the click and maximum right is kindling position.
IMPORTANT: Kindling position may only be used during priming the insert. Continuous use may damage the insert or overheat the installation and laeadto uncontrolled fire.Area between A and B = kindling position. Area between B and C = normal operating range.
IMPORTANT!: Service access to the air regulation system below the insert must be ensured for all surroundings.
FIG 10The air vent control lock can be removed (NOT APPLICABLE IN NORWAY). Use a 2,5 mm allen key to remove it.
5. Lighting a fire for the first time
When the insert is assembled and all instructions have been observed, a fire can be lit. Take care when inserting logs into the burn chamber, in order not to damage the Thermotte plates. This will be resolved once the humidity has evaporated. If needed leave the door slightly open the first 2-3 times the insert is used. It is advisable to ventilate the room well when using for the first time as the varnish on the product may release some smoke or smell. Both the smoke and smell will disappear and are not hazardous.
Warning!In order to avoid injuries, please be aware that the surfaface may become hot during operation and extra care need to be taken to avoid skin burn.
Kindling wood
Finely chopped (diameter of 3-5cm)Length: 20-50cmCa. amount pr lighting : 2,3 kg Place the air vent control in ignition (FIG A) Insert small, dry pieces of wood, ignite and ensure the flames have taken proper hold of the wood. When the flames are stable and the chimney is warm, push in the air control out of the ignition mode and regulate the fire normally. When there is a glowing layer of ash, new wood logs can be inserted. Pull the hot ember to the sides of the combustion chamber when inserting new logs so that the wood is ignited from the bottom. Insert 2 logs. One positioned diagonally to the bottom with left end closer to left front side of window pane. The second leaned against first one also diagonally in opposite direction. Set the air vent on 45% air valve opening. The fire should burn with bright and lively flames.
Reload sizeChopped woodLength: <50cmNormal load size. 3 kg /h(Max load size: 3,8 kg/h)
6. Maintenance
Cleaning and inspection
The insert should be inspected thoroughly and clened at least once per season (possibly in combination with the sweeping of the chimney and chimney pipes). Ensure that all joints are tight and that the gaskets are rightly positioned. Exchange any gaskets that are worn or deformed.
Remember that the insert must always be cold when inspected. The inspection shall be performed by the Professional servicemen.
Ashes
The ashes should be removed at regular intervals. Be aware that the ashes can contain hot ember even several days after the fire is finished. Use a container of non-combustible material to remove the ashes. It is recommended to leave a layer of ashes in the bottom as this further insulates the burn chamber. Take care with the Thermotte plates when the ashes are removed, particularly when using an ash shovel, so as not to damage them.
Thermotte™
The insulation plates (Thermotte -FIG 11) are classified as “wear and tear” parts which will require to be exchanged after some years. The wear time will depend on the individual use of your product. Nordpeis offers a one-year warranty on these parts. After this, replacements can be purchased.

Please note: Wood logs that are too long can cause additional strain and crack the plates, due to the tension created between the side plates.
Door and Glass
Should there be any soot on the glass it may be necessary to clean it. Use dedicated glass cleaner, as other detergents may damage the glass. (NB! Be careful, even dedicated glass cleaner can damage the varnish on the door frame and the gaskets). A good advice for cleaning the glass is to use a damp cloth or kitchen roll paper and apply some ash from the burn chamber. Rub around the ash on the glass and finish off with a piece of clean and damp kitchen roll paper. NB! Only clean when the glass is cold. Periodically, it may be necessary to change the gaskets on the door to ensure that the burn chamber is air tight and working optimally. These gaskets can be bought asa set, usually including ceramic glue.
Recycling of ceramic glass
Ceramic glass cannot be recycled. Old glass, breakage or otherwise unusable ceramic glass must be discarded as residual waste. Ceramic glass has a higher meltingtemperature, and can therefore not be recycled together with glass. If mixed with ordinary glass, it would damage the raw material and could, in worst case endthe recycling of glass. It is an important contribution to the environment to ensure that ceramic glass does not end up with the recycling of ordinary glass.
Packaging Recycle
The packaging accompanying the product should berecycled according to national regulations.
7. Warranty
Warning! Use replacement parts recommended only by the Manufacturer
Warning!Any unauthorized modification of the appliance without written permission of the Manufacturer are prohibited.For detailed description of the warranty conditions see the enclosed warranty card or visit our website www.nordpeis.com
8. Advice on lighting a fire
The best way to light a fire is with the use of lightening briquettes and dry kindling wood. Newspapers cause a lot of ash and the ink is damaging for the environment.Advertising flyers, magazines, milk cartons and similar are not suitable for lighting a fire. Good air supply is important at ignition. When the flue is hot the draughtincreases and door can be closed
Warning: NEVER use a lighting fuel such as petrol, karosine, alcohol or similar for lighting a fire. This could cause injury to you as well as damaging the product.
Use clean and dry wood with a maximum moisture content of 20%. Humid wood requires a lot of air for the combustion, as extra energy/heat is required for drying the humid wood and the heat effect is therefore minimal. This in addition creates soot in the chimney with the risk of creosote and chimney fire.
In case of a chimney fire, close the door and air supplies on the stove / insert and call the Fire Brigade. After a chimney fire the chimney must in all cases be inspected by an authorized chimney sweeper before you use the appliance again.
Storing of wood
In order to ensure that the wood is dry, the tree should be cut in winter and stored during the summer, covered and in a location with adequate ventilation. The wood pile must never be covered by a tarpaulin lying against the ground as the tarpaulin will then act as a sealed lid that will prevent the wood from drying. Always keep a small amount of wood indoors for a few days before use so that moisture in the surface of the wood can evaporate.
Usage
Not enough air to the combustion may cause the glass to soot. Hence, supply the fire with air just after the wood is added, so that the flames and gases in the combustion chamber are properly burnt. Open the air vent and have the door slightly ajar in order for the flames to establish properly on the wood.Note that the air supply for the combustion also can be too large and cause an uncontrollable fire that very quickly heats up the whole combustion chamber to anextremely high temperature (when using with a closed or nearly closed door). For this reason you should never fill the combustion chamber completely with wood.
Warning!The Firebox shall to be always closed except during ignition, refueling and ash removal.
Choice of fuel
All types of wood, such as birch, beech, oak, elm, ash and fruit trees, can be used as fuel in the insert. Wood species have different degrees of density – the moredense the wood is, the higher the energy value. Beech, oak and birch has the highest density.
Attention!We do not recommend using fuel briquettes/ compact wood in our products. Use of such fuel may cause the product to overheat and exceed the temperatures determined safe. Burning briquettes/ compact wood is done so at your own risk and only small amounts (max 1/3 of normal load) should be used for each load.
Warning:Make sure the insert is not overheated it can cause irreparable damage to the product. Such damage is not covered by the warranty.
Warning:NEVER use impregnated wood, painted wood, plywood, chipboard, rubbish, milk cartons, printed material or similar. If any of these items are used as fuel the warranty is invalid. Common to these materials is that during combustion they can form hydrochloric acid and heavy metals that are harmful to the environment, yourself and the insert. Hydrochloric acid can also corrode the steel in the chimney or masonry in a masonry chimney. Also, avoid burning with bark, sawdust or other extremely fine wood, apart fromwhen lighting a fire. This form of fuel can easily cause a flashover that can lead to temperatures that are too high.Source “Håndbok, effektiv og miljøvennlig vedfyring” by Edvard Karlsvik SINTEF Energy Research AS and Heikki Oravainen, VT
