5.3 Break-In Procedure
The Jøtul F 400 is constructed of cast iron and stove 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 400 :
1. Light a small fire of newspaper and kindling. Only allow the 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.
To monitor the stove’s temperature, use a magnetic stove-top thermometer, placed directly on the corner of the stove’s top plate.
Note: Keep the stove under 400°F (204°C) surface temperature during any “break-in fireâ€, with the exception of the last “break-
in†fire. If the temperature exceeds 400°F, 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 is out and the stove has cooled to room temperature, continue the break-in procedure.
Never attempt to reduce the temperature by removing burning logs from the fire.

Note: It is normal for a new painted stove to emit an odor and
smoke during its first several fires. This is caused by the seasoning
of the high temperature paint and will diminish with each fire.
Opening a window or door to provide additional ventilation will alleviate this condition.
Sounds like you got it almost ready to go 24/7
