Maintenance - Jøtul 150 FL Installation & Operating Instruction

english
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. When 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»
for information.
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 I 150 FL is equipped with an air wash for the glass. Air is
sucked in through the air vent above the fireplace 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 wash vent. Most of the soot layer will normally be burned
off when the air wash 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
• Lift out the ash retainer
• Use a shovel or similar and scrape out the ash. Leave a little
ash in the bottom of the combustion chamber as a protective
insulating layer.
Optional equipment includes a solution for dealing with ashes.
See the section: «9.0 Optional equipment».
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 stove
during use. Soot is a good insulator and will therefore reduce the
stove's heat output. Any build up of soot deposits during use can
be removed 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 Sweeping of flue pipes to the
chimney
The flue must be swept through the stove's door opening. The
baffle plate must first be removed. See separate section under:
«7.0 Service».
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.
