3.0 Safety
NB! To guarantee optimal performance and safety, Jøtul recommends that its stoves are fitted by a qualified installer (see www.jotul.com for a complete list of dealers).
Any modifications to the product by the distributor, installer or consumer may result in the product and safety features not functioning as intended. The same applies to the installation of accessories or optional extras not supplied by Jotul. This may also be the case if parts that are essential to the functioning and safety of the fireplace have been disassembled or removed.
In all these cases, the manufacturer is not responsible or liable for the product and the right to make a complaint becomes null and void.
3.1 Fire Prevention Measures
There is a certain element of danger every time you use your fireplace. The following instructions must therefore be followed:
- The minimum safety distances when installing and using the fireplace are given in fig. 1.
- Ensure that furniture and other flammable materials are not too close to the fireplace. Flammable materials should not be placed within 1 metre of the fireplace.
- Allow the fire to burn out. Never extinguish the flames with water.
- The fireplace becomes hot when lit and may cause burns if touched.
- Only remove ash when the fireplace is cold. Ash can contain hot embers and should therefore be placed in a non-flammable container.
- Ash should be placed outdoors or be emptied in a place where it will not present a potential fire hazard.
In case of chimney fire:
- Close all hatches and vents.
- Keep the firebox door closed.
- Check the loft and cellar for smoke.
- Call the fire service.
- Before use after a fire an expert must check the fireplace and the chimney in order to ensure that it is fully functional.
3.2 Floor
Foundation
You need to make sure the foundation is suitable for a fireplace. See «2.0 Technical Data» for specified weight.
We recommend the removal of any flooring that is not attached to the foundation («floating floors») beneath the installation.
Requirements for protection of wooden flooring beneath the fireplace
The product has integrated floor protection and may therefore be placed directly on a wooden floor.
Any inflammable floor coverings, such as linoleum, carpets, etc. must be removed from under the product.
Requirements for protection of inflammable floors in front of the fireplace
The front plate must comply with national laws and regulations. Contact your local building authorities regarding restrictions and installation requirements.
3.3 Walls
Distance to walls made of combustible material - see fig. 1.
The fireplace may be used with an uninsulated flue pipe provided the distances between the fireplace and walls made of combustible materials are as shown in fig. 1.
Ensure that furniture and other flammable materials are not too close to the fireplace. Flammable materials should not be placed within 800 mm of the fireplace.
3.4 Ceiling
If the ceiling above the fireplace is made of a combustible material, the minimum distance between the fireplace and ceiling must be 500 mm.
3.5 Air supply
There must be a flow of air between the burn chamber and the surround. This is to ensure that any build-up of heat inside the surround is not too great. NB: It is extremely important not to cover air openings. See fig. 1 for distances.
ENGLISH
3.6 External air
The amount of combustion air for Jotul's products is approximately 25 - 40m^3 /h
A flexible supply hose allowing external air to be fed directly into the product can be installed as follows:
- Through a hole cut where marked in the bottom plate.
- Through the hole at the back of the surround.
Suggested installation of the flexible hose for combustion air:

Fig. 2a, through an outside wall
Fig. 2b, through the floor and ground plate


Fig. 2c, through the floor and basement

Fig. 2d, indirectly through an outside wall
3.7 Steel chimney
If a top-mounted steel chimney is used, an uninsulated pipe must run from the insert to approximately 10 mm over the top grate.

Fig. 3
Then fit the steel chimney in accordance with the operating instructions.
4.0 Installation
NB: Check that the fireplace is undamaged before installation begins.
NB: The product is heavy! Ensure you have help when positioning and installing it. Make sure the product does not topple over.
NB: Read the Installation and Operating instructions carefully before installing the fireplace!
It is recommended that you test-mount the surround to adjust the insert and flue pipe connection.
Use the acrylic sealant provided for all joints.
4.1 Prior to installation
The basic product comes in two packages:
-
Burn chamber.
-
Concrete units with mounting sections.
NB: Check that there is no visible damage to the product when you unpack it.
Preparations
Before installation, it is necessary to decide:
- Where the smoke outlet is to be located.
Possible use and location of external air supply.
Refer to manuals for installation of the parts.
You will need the following tools to install the product: Spirit level, ratchet with 10 mm and 13 mm sockets and hex keys with 5 mm socket.

Fig. 4
- Remove the packaging (cardboard and wooden frame) and spread the cardboard out on the floor behind the fireplace.
- Leave the stove standing on the transport pallet.
- Remove the top plate (Fig. 4 A) with the top grate (Fig. 4 B). These parts are not to be used.
- Remove the gloves and bowl from the ash pan. The bowl will not be used.
- Check that the control handles (Fig. 4 C) move freely.

Fig.5
- Carefully lay the stove down on its back. Rest the stove on a pallet and three packaging frames (see Fig. 5).

Fig. 6
- Screw in the 4 threaded bars.

Fig. 7
- Mount the outside air connection with 4 nuts and washers (Fig.7A).

- Mount the adjusting nuts on threaded bars.
ENGLISH
4.2 Chimney and flue pipe
- The fireplace must only be connected to a chimney and flue pipe approved for solid fuel fireplaces with flue gas temperatures as specified in «2.0 Technical Data».
- The cross-section of the chimney must be designed to fit the fireplace. Use «2.0 Technical Data» to calculate the correct chimney cross-section.
- The chimney must be connected in accordance with the installation instructions of the chimney supplier.
Before a hole is made in the chimney, the product should be test-mounted in order to correctly mark the position of the fireplace and the hole in the chimney. See Fig.1 for minimum dimensions. - Make sure that the flue pipe rises all the way up to the chimney.
- With a rear outlet, use a flue pipe bend with a sweep hatch to allow sweeping.
- Please note that it is extremely important for connections to have a degree of flexibility. This is to prevent any movement in the installation leading to the formation of cracks.
- For recommended chimney draught, see «2.o Technical Data». For flue pipe dimensions with the relevant cross-section, see «2.o Technical Data».
NB! The minimum recommended chimney length is 3.5m from the flue pipe insert. If the draught is too strong, a flue pipe damper can be installed and used to reduce the draught.
4.3 Installation

Fig. 8
- The base should be put in place. Check it is level using a spirit level and adjust as necessary using adhesive or mortar.

5.0 Installation completed
See Installation instructions with technical data for Jøtul F 480 (cat. no. 10047258) for use and maintenance of the product!
5.1 Painting
Painting can take place the day after installation. Use waterbased paint. If you prefer a little surface texture, a little tile cement may be mixed into the paint.
5.2 Minor damage
Once the insert has been installed you should fill in any nicks or irregularities in the concrete. You can use the accompanying cement filler.
- In order to achieve the best result the surround should be rubbed down with fine sandpaper, smoothing any unevenness or sharp edges prior to painting.
- Then apply one coat.
- Mix the powder (cement filler) with water to form a smooth paste (like toothpaste).
- Smooth away any unevenness, allow to dry and rub down with fine sandpaper.
- If the hole is deep, we recommend that the filler be applied in two stages to prevent it sinking.
- Apply a second coat of the desired colour.
5.3 Cracks
In some instances, small cracks may appear at the joints after a few months' use due to settling of the building. These cracks can be easily repaired:
- Open up the crack with a tool, e.g. a screwdriver, to create more room for the grouting cement.
- First remove any dust using a vacuum cleaner. Then inject some acrylic grout, and smooth it off using a wet, soapy fingertip.
After a couple of days the joint can be repainted.

- A wooden pallet that can be cut up and burned in the fireplace.
- Cardboard packaging that should be taken to a local recycling facility.
- Plastic bags that should be taken to a local recycling facility.
7.2 Recycling the fireplace
The fireplace is made of:
- Metal that should be taken to a local recycling facility.
- Glass that should be disposed of as hazardous waste. The glass in the fireplace must not be placed in a regular source segregation container.
- Vermiculite burn plates that can be disposed of in regular waste containers.
8.o Warranty
Jøtul AS provides its customers with a ten-year warranty with the right to return external cast-iron items if they show defects as a result of faulty materials and/or manufacturing after the initial purchase/installation of the fireplace. The buyer is entitled to return the goods provided that the fireplace has been installed in compliance with current laws and regulations and in compliance with Jøtul's installation and operating instructions.
The warranty does not cover:
The installation of optional extras, for example, to rectify local draught conditions, air supply or other circumstances beyond Jotul's control. The warranty does not cover consumables, such as burn plates, smoke baffles, fire grates, bottom grates, brick refractories, dampers and gaskets as they deteriorate over time due to normal wear and tear. The warranty does not cover damage caused as a result of using unsuitable fuel when lighting the fire, such as driftwood, impregnated and painted wood, plank offcuts, chipboard, etc. Overheating may easily occur if unsuitable fuel is used, i.e. the fireplace becomes red hot, which causes the paint to discolour and the cast iron parts to crack.
The warranty is not valid for damage caused while the product is in transit from the distributor to the delivery address. The warranty is not valid either for damage caused by the use of non-original parts.
