Break-In Procedure; Starting And Maintaining A Fire - Jøtul F600 Firelight Installation And Operating Instructions Manual

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.
When first starting or reviving the fire: the primary control
lever should be set to the far right position, which permits 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. See figure 11.
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.
You should 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. 12. 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 600 Firelight 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 400 CB:
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.
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 odor and smoke during initial fires,
depending upon temperatures over time.
This is caused by the seasoning of the high
temperature paint and production material.
Opening a window or door to provide additional
ventilation will alleviate this condition.

5.6 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 OPERATION. BURNING 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. With the primary air control lever in the full open position (to
the right), start with several sheets of crumbled 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 larger 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 might damage the
stove.
3. Once the stove has reached a surface temperature range of
between 400° and 600°, (204°C -316°C), adjust the primary
air control lever as necessary to generate the heat output and
burn time desired.
Jøtul recommends use of a magnetic 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). for the best
locations to place a stove-top thermometer.
Top-Down Fire Building - See fig. 14.
Many people find this method to be superior to the traditional
method.
1. With the primary air control lever in the full open position (to
the right), place two short 1/4-split logs on the firebox floor,
perpendicular to the rear wall, about 6 inches apart.
2. Place kindling across the base logs.
3. Place one or two smaller logs on top of the kindling.
5. Place newspaper between the two bottom logs under the
kindling. Light the news paper and close the door. Continue
to add kindling and small logs as necessary to build the fire.
Keep the air control fully open until the fire is well-established.
