Secondary air
allows combustion of volatile gas and other
by-products of primary combustion that would otherwise
enter the atmosphere unburned. This unregulated air
is preheated as it passes over the back of the stove and
through a stainless steel manifold at the top of the firebox.
This additional hot oxygen allows any unburned gasses
to be burned inside the stove. The action of secondary
combustion can be readily seen through the viewing glass
a slow, rolling flames suspended over the main fuel bed
and smaller jets of flame extending from the secondary
manifold ports. At the same time, no smoke will be
observed exiting the chimney. This is evidence that the
stove is operating at the so-called ”sweet-spot” wherein
optimum efficiency is realized.
Start-Up Air Control
The start-up air control lever is located below the glass in
the center of the front door. This control is for “start - up”
air only and should not be used to freshen an existing fire
or during refueling. Never leave the stove unattended
while this control is open, overfiring could result, which
can damage the appliance. See

Use a Stove-top Thermometer
Determining the primary air setting for the best overall
performance for your particular needs and installation
will be established over time through trial and error. Each
installation has unique characteristics that will affect
stove performance. Use a stove-top thermometer to
monitor the status of the fire. Place the thermometer
on the stove top, centered two one side or the other. See
fig. 16. Generally speaking, once the stove temperature
has reached 400°F - 600°F, the air control may be set in a
mid-range position to allow adequate oxygen to support
efficient combustion throughout the burn cycle.

5.5 Break-In Procedure
The Jøtul F
3
CB is constructed of cast iron and stove
furnace cement. Cast iron, while very durable, expands
and contracts as it is heated and cooled. This type of
construction requires the stove to be “broken-in” gradually
so that thermal expansion does not occur too quickly. The
following steps describe the proper break-in procedure for
the Jøtul F 3
CB:
1. Light a small fire of newspaper and kindling. Only al-
low the stove to reach a maximum surface tempera-
ture 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
: Keep the stove under 400°F (204°C) surface
temperature during any “break-in fire”, 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.
