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 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 Jøtul. 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.
The Clean Air Act
“The Clean Air Act 1993 and Smoke Control Areas”
Under the Clean Air Act local authorities may declare the
whole or part of the district of the authority to be a smoke
control area. It is an offence to emit smoke from a chimney of
a building, from a furnace or from any fixed boiler if located in a
designated smoke control area. It is also an offence to acquire
an “unauthorised fuel” for use within a smoke control area
unless it is used in an “exempt” appliance (“exempted” from
the controls which generally apply in the smoke control area).
The Secretary of State for Environment, Food and Rural
Affairs has powers under the Act to authorise smokeless
fuels or exempt appliances for use in smoke control areas in
England. In Scotland and Wales this power rests with Ministers
in the devolved administrations for those countries. Separate
legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland. Therefore it is a requirement that
fuels burnt or obtained for use in smoke control areas have
been “authorised” in Regulations and that appliances used to
burn solid fuel in those areas (other than “authorised” fuels)
have been exempted by an Order made and signed by the
Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act
can be found here : http://smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean
Air Act 1993 including designation and supervision of smoke
control areas and you can contact them for details of CleanAir
Act requirements”.

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. The specified distance to
flammable materials, applies to this stove. The stove must
be installed with a CE approved flue. The distance of the
flue pipe to combustible materials must also be observed.
• Ensure that furniture and other flammable materials are not
too close to the fireplace. Flammable materials should not
be placed within 1100 mm 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
Youneed tomake surethefoundationissuitablefor afireplace.
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
Jøtul F 370 Advance Series has a heat shield underneath
which protects the base from radiation. The product has
an integrated floor protection and may therefore be placed
directly on a wooden floor.

Fresh air supply
The air used for combustion in any well-insulated house needs
to be replaced. This is particularly important in houses with
mechanical ventilation. Such replacement air can be procured
in several ways. The most important thing is to supply the air
to the room where the stove is placed. Place the outside wall
valve as close to the stove as possible and make sure that it
can be closed when the stove is not in use.
For the fresh air supply connection, follow the national and
local building regulations.
Important! Ensure that air vents in the room where the
fireplace is located are not blocked.

4.7 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 specified distance to flammable materials, applies to
this stove.
• The stove must be installed with a CE approved flue.
• The distance of the flue pipe to combustible materials must
also be observed.
• 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.
• 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 «2.0 Technical
Data». For flue pipe dimension see “2.0 Technical Data”.
NB: The chimney’s diameter must be at least just as
big as the flue pipe.
NB! The minimum recommended chimney length is 3.5 m
from the flue pipe insert. If the draught is too strong, a flue
pipe damper can be installed and used to reduce the draught.

4.8 Performance check
Once the product has been assembled, always check the
control handles. These should move easily and work in a
satisfactory manner.
The Jøtul F 370 Advance is equipped with the following
operating options:

4.9 Use
• Open the air vent and the ignition vent by pulling it out all
the way (A). If necessary, keep the door slightly open. (Use
a glove, for example, as the handle can become hot.)
• Place two medium sized logs in/out on each side of the
base. N.B. In order to avoid sooting on the glass, it is
important that the log is not placed adjacent to the glass
on the product.
• Crumple some newspaper (or birch bark) between these
and add some kindling wood in a criss-cross pattern on top
and light the newspaper.
• Gradually increase the size of the fire, but the wood should
not be stacked higher than the horizontal holes on the back
burn plate. See fig. 30 C.
• Finally, place a medium-sized log on the top of the pile.
• Place 2 or 3 briquettes or kindling sticks under the top layer
of kindling and light the fire.
• NB: The maximum height of the pile of the wood should
be just below the horizontal holes. The holes must not be
covered.
• Check that the afterburning (secondary combustion) starts.
This is best indicated by yellow, flickering flames under the
baffle.
• Then regulate the rate of combustion to the desired level of
heating by adjusting the air vent (fig. 30 A).
• Close the stove door. It must always be closed when the
fire is lit.
Fig. 31
Adding firewood
Stoke the stove frequently but only add small amounts of fuel
at a time. If the stove is filled too full, the heat created may
cause extreme stress in the chimney. Add fuel to the fire in
moderation.Avoid smouldering fires as this produces the most
pollution. The fire is best when it is burning well and the smoke
from the chimney is almost invisible.
ENGLISH

4.7 Danger of overheating
The fireplace must never be used in a manner that causes
overheating.
Overheating occurs when there is too much fuel and/or too
much air so that too much heat develops. A sure sign of
overheating is when parts of the fireplace glow red. If this
happens, reduce the air vent opening immediately.
Seek professional advice if you suspect that the chimney is
not drawing properly (too much/too little draught). For further
information, see «4.0 Installation» (Chimney and flue pipe).
4.8 Ash removal
JøtulF 370Advance hasan ashpanwhich makesiteasy toremove
the ashes.
• Only remove ashes when the fireplace is cold.
• Push/pull the handle for the ash grate/ignition vent out and
in several times so that the ashes fall down into the ash
pan. Use something like a glove to grab the handle on the
ash pan.
• Make sure that the ash pan doesn’t fill up so high that it
keeps ash from coming through the grate into the pan.
5.0 Daily use
Odours when using the fireplace for the first time
When the fireplace is used for the first time, it may emit an
irritating gas which may smell slightly. This happens because
the paint dries.The gas is not toxic but the room should be
thoroughly ventilated. Let the fire burn with a high draught
until all traces of the gas have disappeared and no smoke or
odours can be detected.
Heating advice
NB: Logs that have been stored outdoors or in a cold room
should be brought indoors 24 hours before use to bring them
up to room temperature.
There are various ways of heating the stove but it is always
important to be careful about what you put in the stove. See
the section on “Wood quality”.
Wood quality
By quality wood we mean most well-known types of wood such
as birch, spruce and pine.
The logs should be dried so that the moisture content is no
more than 20%.
To achieve this, the logs should be cut during the late winter.
They should be split and stacked in a way that ensures good
ventilation. The wood stacks should be covered to protect the
logs from rain. The logs should be brought indoors during early
autumn and stacked/stored for use in the coming winter.
Be especially careful never to use the following
materials as fuel in your fireplace:
• Household rubbish, plastic bags, etc.
• Painted or impregnated timber (which is extremely toxic).
• Laminated wooden planks.
• Driftwood
These may harm the product and are also pollutants.
NB: Never use petrol, paraffin, methylated spirit or similar
liquids to light the fire. You may cause serious injury to
yourself and damage to the product.
Wood consumption
Jøtul F 370 Advance has a nominal heat output of ca. 6 kW.
Use of wood, with nominal heat emission: Approx. 2,1 kg/h.
Another important factor for proper fuel consumption is that
the logs are the correct size. The size of the logs should be:
Kindling:
Length: 27-30 cm
Diameter: 2-5 cm
Amount per fire: 6-8 pieces
Firewood (split logs):
Length: Ca 27 - 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 1.6 kg
Amount per load: 2 pieces
Nominal heat output is achieved when the ignition and air vent
is open approximately 22% (fig. 30 A), pulled out about 12,5
mm.
5.1 How wind and weather affect the
stove
The performance of the stove can be affected considerably by
the wind acting on the chimney at different strengths. It may
therefore be necessary to adjust the air supply to ensure good
combustion performance. It might also be a good idea to install
a damper in the flue pipe so that the chimney draught can be
regulated according to the strength of the wind.
Fog and mist can have a significant impact on the chimney
draught and it might be necessary to use other combustion air
settings to ensure good performance.
5.2 The importance of the chimney
The chimney is the engine that drives the fireplace and it’s
essential to have a good chimney in order for the fireplace
to function properly.
The draught in the chimney creates a vacuum in the stove.
The combustion air is also used for the airwash system that
keeps the window clear of soot.
The draught in the chimney is caused by the difference in
temperatures inside and outside the chimney. The greater
the temperature difference, the better the draught in the
chimney. It is therefore important to allow the chimney to reach
operating temperature before adjusting the air vents to restrict
combustion in the stove (a brickwork chimney takes longer to
reach operating temperature than a steel chimney).

It is particularly important to reach operating temperature
as quickly as possible on days on which the draught in the
chimney is poor due to unfavourable wind and weather
conditions. Make sure the fuel ignites as quickly as possible.
Practical tip: Chop the wood into much smaller pieces and use
an extra firelighter.
NB: If the stove has not been used for some considerable
time, it is important to check the chimney pipe for blockage.
6.0 Maintenance
6.1 Cleaning the glass
The product is equipped with an air wash for the glass. Air is
sucked in through the air vent on the top of the product and
down along the inside of the glass.
However, some soot will always stick to the glass, but the
quantity will depend on the local draught conditions and
adjustment of the air vent. Most of the soot layer will normally
be burned off when the air vent is opened all the way and a fire
is burning briskly in the fireplace.
Good advice! For normal cleaning, moisten a paper towel
with warm water and add some ash from the burn chamber.
Rub it over the glass and then clean the glass with clean water.
Dry well. If it is necessary to clean the glass more thoroughly
we recommend using a glass cleaner (follow the instructions
on the bottle).
6.2 Cleaning and soot removal
Soot deposits may build up on the internal surfaces of the
fireplace during use. Soot is a good insulator and will therefore
reduce the fireplace’s heat output. If soot deposits accumulate
when using the product, they can be easily removed by using
a soot remover.
In order to prevent a water and tar layer from forming in the
fireplace you should regularly allow the fire to burn hot in order
to remove the layer. An annual internal cleaning is necessary
to get the best heating effect from the product. It is a good idea
to do this in connection with the sweeping of the chimney and
flue pipes.
6.3 Sweeping of flue pipes to the
chimney
On certain free-standing fireplaces the top plate can be lifted
off and the pipe swept through the top.
Otherwise, flue pipes must be swept through the flue pipe
sweeping hatch or through the product’s door opening. Then,
the baffle must be removed.
6.4 Inspection of the fireplace
Jøtul recommends that you personally inspect your fireplace
carefully after sweeping/cleaning. Check all visible surfaces
for cracks. Also check that all joints are sealed and that the
gaskets are in the correct position.Any gaskets showing signs
of wear or deformation must be replaced.
Thoroughly clean the gasket grooves, apply ceramic glue
(available from your local Jøtul dealer), and press the gasket
well into place. The joint will dry quickly.
6.5 Exterior maintenance
Painted products maychangecolour afterseveral years usage.
The surface should be cleaned and brushed free of any loose
particles before new paint is applied.
Important! Never place anything on the top plate of the
stove. This could cause permanent damage to the paint
or enamel.
7.0 Service
