2. Light a second fire, allowing the stove to reach a maximum
temperature of 400°F (204°C) for 1 hour.
3. Cool the stove to room temperature.
4. Light a third fire and gradually allow the stove to reach
and maintain a surface temperature of 500°F (260°C).
5. 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 minimize the air supply. It is normal for
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.
5.7 Starting and Maintaining a Fire
Burn only solid wood directly on the bottom grate of the
stove. Do not elevate the fire in any way.
WARNING: THE ASH PAN DOOR MUST ALWAYS BE
SECURELY CLOSED WHEN THE STOVE IS IN BURNING.
OPERATING THE STOVE WITH THE ASH DOOR OPEN WILL
PROMOTE UNEVEN THERMAL EXPANSION AND CAN
RESULT IN DAMAGE TO THE STOVE AND VOID YOUR
WARRANTY.
Traditional Fire Building
1. Set the primary air control lever in the full open
position (to the right). Place several sheets of
crumpled newspaper placed directly on the grate. On
top of the newspaper, place several pieces of small
dry kindling (approx. 1” in diameter) with two to three
small logs (approx. 3” to 5” in diameter) on top.
2. Light the fire and close the door, slowly building the
fire by adding larger and larger logs. Be sure to follow
the break-in procedure before creating a hot fire that
could damage the stove.
3. Once the stove has reached a temperature range of
between 500° and 600°, (260°C -316°C), adjust the
primary air control lever as necessary to generate the
heat output and burn time desired.
You can also use a stove top thermometer to monitor
the surface temperature of the stove. The optimum
surface temperature range for the most efficient burn
is between 400° and 600° (204°C -316°C).
2. Take the magnet off of thermometer and replace into the
correct orientation as shown in fig. 13
c-13e.
3.
Place the thermometer fully into hole with magnet to cast
as shown in figs. 13b .
Seated within the right side directly behind the
catalytic element, the thermometer accurately reports
combustion activity. Secondary combustion takes place at
temperatures between 500°F (260°C) and 1200°F
(260°C - 649°C).
The primary air valve should remain at the fully
open setting, (to the Right), at least until the monitor
registers 500°F (260°C). Maintain that temperature for
15-20 minutes before adjusting the primary air lever
to Medium Low - Medium High settings. The optimum
temperature range for most efficient combustion is
between 500°F and 800° (260°C -371°C). Chimney draft
should be in the .05 - 1.0 w.c. range. The so-called “sweet
spot” combustion zone is best maintained at those
temperatures.
Visual Monitoring
Evidence of efficient combustion can be observed in
three distinct ways:
1. At temperatures over 500° F, look up through the
door glass to the steel baffle and catalytic element at
the top of the firebox. As exhaust gases ignite, jets of
flame can be seen projecting from the baffle ports
and the catalyst will glow vividly red.
2. Little or no smoke will be seen flowing from the
chimney flue outside of the house.
3. If the stove has been properly operated, brushing
the chimney flue will produce mostly fly ash. Little or
no creosote accummulation will be evident.
See appendix A for more information regarding combustor
performance.
5.6 Stove Break-In Procedure
The Jøtul F 500 V3 is constructed of cast iron plates
and sealed with 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. this process is accomplished
by burning a short series of small-to-medium fires as
described below.
1. Fully open the primary air valve. Light a small fire of
newspaper and kindling. Only allow the stove monitor to
reach a temperature of 200°F (93° C). Maintain the fire at
that level for approximately 1 hour and allow the stove to
cool to room temperature.
