5.6 Adding firewood
1. Each load should burn down to embers before new firewood is
added. Open the door slightly and allow the negative pressure
to level out prior to opening the door completely.
2. Add the wood and make sure that the air vent is fully open
for a few minutes until the wood has caught fire.
. Close the air vent (fig. 6) once the wood has properly ignited
and is burning well. Check that afterburning (secondary
combustion) starts.
N.B. Danger of overheating: the fireplace must never be used in
a manner that causes overheating.
Overheating occurs when there is too much wood and/or air so
that too much heat is developed. A sure sign of overheating is
when parts of the fireplace glow red. If this happens, reduce the
ventilation opening immediately.
Upon suspicion of excessive/poor draught in the chimney, seek
professional help. See also «2.0 Technical data» and «4.5 Chimney
and flue pipe» for information.
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 installation
in order to ensure that it is fully functional.
5.7 Using fireplace during the
transition from winter to spring
During a transitional period with sudden fluctuations in
temperature, negative smoke draught or under difficult wind
conditions, disturbances in the chimney draught may occur so
that the smoke gasses are not drawn out.
One should then use less firewood and have a larger opening in
the air vents so that the wood burns fresher and faster. In this
was the draught in the chimney will be maintained.
To avoid accumulated ash, it should be removed more often than
usual. See «6.2 Ash removal».

6.0 Maintenance

6.1 Cleaning the glass
Jøtul F 602 is equipped with an air wash for the glass. Air is sucked
in through the slide above the door 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 Ash removal
• Use a scoop or similar to remove the ash through the door.
• Always leave some ash as a protective layer on the bottom
of the fireplace.
• Ash must be placed in a metal container with a sealed lid.
Also see the description below about how to handle ash: «3.0
Safety precautions».
6.3 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 sweeping the chimney and flue pipes.
6.4 Cleaning the flue pipe to the
chimney
The easiest way to clean the stove is through the door. To clean
the flue pipe, just remove the cooking plate.
6.5 Checking the fireplace
Jøtul recommends that you personally check your fireplace
carefully after sweeping/cleaning. Check all visible surfaces for
cracks.
Also check that all joints are sealed and that the door and top
plate gaskets are in the correct position. Any gaskets showing
signs of wear or deformation must be replaced.
Thoroughly clean the gasket groove, apply ceramic glue (available
from your local Jøtul dealer), and press the gasket well into place.
The joint will dry quickly.
