Operation
Please read the following section before building a fire in
your new Jøtul F 100 USA.

Use Solid Wood Fuel Only

First this stove is designed to burn natural wood only.
Wood that has been air-dried for a period of 6 to 14 months
will provide the cleanest, most efficient heat.
Do not burn:
• Coal • Treated or painted wood
• Garbage • Chemical Chimney cleaners
• Cardboard • Colored paper
• Solvents • Any synthetic fuel or logs
• Drift wood • Laminated wood
The burning of any of these materials can result in the
release of toxic fumes. Never use gasoline, gasoline-type
lantern fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen-up” the fire. Always keep such
liquids away from the heater at all times.
Important: Never build or allow the fire to rest directly on
the glass panels. The logs should always be spaced at
least one inch from the glass to allow for proper air flow
within the firebox.

combustion air and to the left to decrease combustion air.

Controls on the Jøtul F 100 USA

Combustion air is controlled by the Primary Air Lever,
located above the Loading Door. The lever actuates a
shutter over the air inlet which regulates the volume of
primary air entering the firebox and controls heat output
and burn time. See fig. 13.
When first starting or reviving the fire: the primary control
lever should be at the far right position, which allows the
maximum amount of air into the stove. The greater the
amount of air entering the stove, the hotter and faster
the fire will burn.
Moving the lever to the left reduces the airflow into the
stove which prolongs the fire at a lower heat output.

Air Flow / Performance

Primary air enters the firebox directly above the glass
panel on the door. The incoming air creates a turbulent
barrier or “airwash” between the glass and the fire.
Reducing the flow of primary air directly reduces the
effectiveness of the airwash. Determining the primary
air setting for the best overall performance for your
particular needs and installation will best be established
over time through trial and error.

Break-In Procedure

The Jøtul F 100 USA is constructed of cast iron and high
temperature furnace cement. This type of construction
requires the stove to be “broken-in” gradually so that
heat expansion does not occur too quickly and cause
damage. The following steps describe the proper break-
in procedure for the Jøtul F 100 USA. Use a magnetic stove-
top thermometer to monitor stove temperature, placed
directly on the top plate.
1 Light a small fire of newspaper and kindling. Only
allowthe stove to reach a maximum surface
temperature of 200°F (93° C). Burn for approximately
1 hour.
2 Allow the stove to cool to room temperature.
3 Light a second fire, allowing the stove to reach a
maximum temperature of 300°F (149°C) for 1 hour.
4 Cool the stove to room temperature.
5 Light a third fire and gradually allow the stove to reach
a surface temperature of 400°F (204°C)
6 Cool stove to room temperature. This completes the
“break-in” procedure.
Note: If the temperature exceeds the limit during any
break-in fire, move the primary air control lever all the
way to the left to shut off the air supply completely. It is
normal that the stove top temperature will continue to
climb until the fuel burns down somewhat. Once the fire
