Operating instructions
Initial lighting and daily use
Jøtul F 400 is a clean-burning product and with additional
supplies of combustion air, it allows for afterburning of
hazardous gases and particles. It is important that the
system is used correctly.
The stove is equipped with certain functions that are
described in the chapter: Control of functions.
Initial lighting
Open the draught vent fully by pushing the vent all the way
to the right (fig. 3-A). Put in some crumpled newspaper,
kindling wood and firewood and start a small fire. Add more
firewood gradually and let the fire burn briskly for a couple
of hours. Let the fire die out and repeat one more time.
Note! Odors when using the stove for the first time.
Painted products. The stove may emit an irritating gas when
used for the first time, and it may smell a little. The gas is
not toxic, but it is recommended to open a window or a
door to provide additional ventilation in the room. Let the
fire burn with a high draught until all traces of gas have
disappeared and no smoke or smells can be detected.
Enamelled products: Condensation may form on the surface
of the stove the first few times it is used. This must be
wiped off to prevent permanent stains forming when the
surface heats up.
Daily use
Fire up with the aid of newspapers and some kindling wood.
Place two medium sized logs in/out on each side of the
base. Crumple some newspaper (or birch bark) between
these and add some kindling wood in a criss-cross pattern
on top and light the newspaper. Increase the size of the
logs gradually

Draught vent (fig. 3- A).
Regulate when the wood is properly
lit and burns well. Check that the afterburning (secondary
combustion) starts. This is best indicated by yellow, flickering
flames in the air chamber. Then regulate the rate of
combustion to the desired level of heating by adjusting the
draught vent.
Always use good quality firewood. It gives the best results
and doesn’t damage the product.
Never burn the following materials in the stove:
- household waste, plastic bags etc.
- painted or impregnated wood (highly toxic)
- chipboard or laminated boards
- driftwood
This may harm the product and pollute the atmosphere.
Note! Never use flammable liquids such as petrol, kerosene,
red spirit or similar to start the fire. This may cause harm to
both yourself and the product.
Note! Danger of overheating: The stove must never be
used in a manner that causes overheating.
Overheating is defined as overfilling the stove with
firewood and/or leaving the draught vent fully open.
The chimney draught should never exceed 2,5 mmVs (25 Pa).
A sure sign of overheating is when parts of the stove glows
red. When this happens, reduce the draught vent opening
immediately

Warning! Each fire should burn down to embers before new
firewood is added.
Maintenance
Cleaning the glass
Jøtul F 400 is equipped with an air wash system. Through
the draught vent air is sucked in above the fireplace and
washed down along the inside of the glass. This system
has the advantage that it provides better combustion and
reduces the buildup of soot deposits on the glass.
Still, some soot will always stick to the glass, but the
quantity will depend on the local draught conditions and
adjustment of the draught vent. Most of the soot layer will
normally be burned off when the draught 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. If it is necessary to clean the glass more thoroughly,
a
glass cleaner is recommended (follow the instructions
for use on the bottle).
Ash removal
Jøtul F 400 has an ash pan which makes it easy to remove
the ash. Scrape the ash through the grate in the base plate
and into the ash pan. Use something like a glove to grab
the handle on the ash pan and take away the ash. Make
sure that the ash pan doesn’t fill up so high that it keeps
ash from coming through the grate into the pan.
Make sure the door to the ash pan is securely shut when
the stove is in use.
Also see the description of how to handle ashes under:
Measures to prevent fires.
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.
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.
