5.7 Controlling the Fire

Combustion intensity is controlled by the position of an air
shutter located under the front door. You adjust its position
using the handle located under the ash lip. Slide the handle
to the left to decrease air to the fire. Sliding it to the right
increases air delivery and consequently, fire intensity.
See fig. 17. The shutter regulates and directs primary air
to the front of the burn chamber. Push it to the right to
allow maximum air to support combustion. It should be
fully open when first starting or rekindling a fire, or when
greater heat output is desired.

5.8 Break-In Procedure

Although your Jøtul F 50 TL Rangeley is constructed of
welded, 1/4" steel plate, it also incorporates cast iron
components. This material 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 your stove. Use a magnetic
stove-top thermometer to monitor stove temperature,
placed directly on the cook plate.
Set the Primary Air Shutter fully open, all the way to the
right.
1. Light a small fire of newspaper and kindling at the
front of the stove. Gradually add small pieces of wood,
but only allow the stove to reach a maximum surface
temperature of 200°F (93° C). Continue burning at this
low rate 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 the stove to room temperature. This completes the
"break-in" procedure.
Note: If the temperature exceeds the limit during any
break-in fire, move the Air Shutter all the way to the left
to shut off the air supply completely. It is normal that the
stovetop 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.
Break-in Odors: It is normal for a newly-painted
stove to emit odor and smoke during the first
few fires, and these may set off smoke alarms.
This condition is caused by curing of the high
temperature paint and will diminish with each
subsequent fire. It is advisable to open windows
or doors to provide plenty of fresh air and cross-
ventilation during the break-in period.

5.9 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: DO NOT OPERATE THIS STOVE WITH THE ASH
DOOR OPEN. DOING SO MAY CAUSE DAMAGE AND WILL
VOID YOUR WARRANTY.
We recommend use of a magnetic stovetop thermometer
to monitor the surface temperature of the stove. Locate
the thermometer directly on one of the rear corners of
the Griddle/Load Door. The optimum surface temperature
range for most efficient combustion is between 400° and
700° (204°C -371°C). Chimney draft should be in the
.05 - 1.0 w.c. range.
1. With the Primary Air Shutter in the full open position
(to the right), start with several sheets of crumpled
newspaper placed directly on the grate. On top of the
newspaper, place several pieces of small dry kindling *
(1" - 2" in diameter or less) with two to three larger logs
(approx. 3" to 4" in diameter) on top.
2. Light the fire and close the door. Allow the chimney to
warm and establish a strong draft. Use your stove glove
and slowly build the fire by adding larger and larger
logs. Be sure to follow the break-in procedure (Sect. 5.6)
before creating a hot fire that might damage the stove.
3. Once the stove has reached a surface temperature range
of between 400° and 700°, (204°C -371°C), adjust the
primary air control lever as appropriate to generate the
desired heat output and burn time.
With time and experience, you will soon become
acquainted with the operating characteristics of your
particular installation.
You can also monitor stove performance through the
window. Peak combustion efficiency occurs when exhaust
gas is burned at the baffle in the top of the firebox. This is
apparent as rolling yellow-orange flames appearing at the
secondary air ports in the underside of the baffle plate and
forward tube. At this stage, little or no smoke will be visible
exiting the chimney.
WARNING:
NEVER OVER-FIRE THE STOVE. IF ANY PART OF THE
STOVE OR CHIMNEY GLOWS, YOU ARE OVER-FIRING.
A HOUSE FIRE OR SERIOUS DAMAGE TO THE STOVE
OR CHIMNEY COULD RESULT. IF THIS CONDITION
OCCURS, IMMEDIATELY CLOSE THE AIR CONTROL.
