5.0 Operation

Please read the following section before building the first
fire in your new Jøtul F 50 TL Rangeley.
5.1 Combustion Efficiency
EPA qualified tested efficiency values are not currently
available for the Jøtul F 50 TL . The EPA default efficiency
for non-catalytic wood heaters is 63% per Federal Register
40 CFR Part 60, Subpart AAA.
There are, however, aspects of efficiency that you should
be aware of in order to get the most from your stove.
Operation habits and fuel moisture can have a significant
effect on efficiency. Poorly seasoned wood having a higher
than optimum moisture content, can reduce the amount
of energy transferred tothe living area as a result of the
energy expended to evaporate the excess fuel moisture
in order for the wood to burn. Operational aspects, such
as not building a robust kindling fire to readily ignite the
larger fuel pieces, can result in an inefficient smoldering
fire. Additionally, most modern wood heaters' optimum
performance and efficiency are at the medium to medium
-low burn rates.
The location of the stove can have a significant effect on
heating efficiency, primarily in regards to distribution of
the heat. For example, a wood heater centrally located
in the residence in an open living area will likely provide
better circulation of heat than will a stove located in a
room adjacent to the larger living area.

5.2 CO Emissions

EPA qualified tested carbon monoxide (CO) values ar not
currently available for the Jøtul F 50 TL. There are, however,
aspects of CO that you should know. Most all means of
combustion produce CO, including wood fires. Maintaining
a well-established fire and avoiding operation that
produces a smoldering, smoky fire, will greatly reduce CO
levels.
It is highly recommended that a CO monitor (detector)
be installed in the same room as the stove. The monitor,
however, should be located as far away as possible from
the stove to avoid alert soundings when adding fuel to the
fire.

5.3 Wood Fuel and Performance

The F 50 TL is designed to burn natural wood only. Higher
efficiencies and lower emissions generally result when
burning air-dried, seasoned hardwoods, as opposed to
softwoods, green or freshly cut hardwoods. Wood that has
been air-dried for a period of 6 to 14 months will provide
the cleanest, most efficient heat. Wood seasoned more

WARNING
ALWAYS WEAR STOVE GLOVES WHILE TENDING THE FIRE.
NEVER ALLOW THE FIRE TO REST DIRECTLY ON THE
GLASS. KEEP THE LOGS SPACED AT LEAST ONE INCH FROM
THE GLASS TO ALLOW FOR PROPER AIR FLOW WITHIN THE
STOVE. AVOID STRIKING THE GLASS WITH LOGS.
OPERATE THIS STOVE ONLY WITH THE FRONT DOOR
AND ASH DOOR FULLY CLOSED. OPERATION WITH THE
DOOR PARTIALLY OPEN MAY RESULT IN OVER-FIRING.
IF THE DOOR IS LEFT PARTIALY OPEN, GAS AND FLAME
MAY BE DRAWN OUT OF THE STOVE CREATING SAFETY
RISKS FROM BOTH FIRE AND SMOKE.
than 2 years will burn too quickly to take advantage of the
stove's low end efficiency strength.
A seasoned log will have check marks on the ends and be
lighter than an unseasoned log which will show little or no
check marks.
We recommed using a moisture meter to determine
the moisture content of your wood. For purposes of home
heating, your fuel should have a moisture content between
12 - 20%. Wood with higher moisture content will burn,
however, very inefficiently. Most of its heat value will be
lost to driving water out of the wood. Worse, that moisture
will condense as creosote in the relatively cool chimney
flue, increasing the potential for a chimney fire. Use of
unseasoned wood defeats the purpose of any modern
wood-burning stove.
DO NOT BURN:
• Coal;
• Garbage;
• Synthetic fuel or logs;
• Material containg rubber, including tires;
• Material containing plastics;
• Waste petroleum products, asphalt products, paints,
paint thinners or solvents;
• Materials containing asbestos;
• Construction or demolitioin debris;
• Railroad ties or pressure-treated wood;
• Manure or animal remains;
• Salt water driftwood or other previously salt-water;
saturated materials;
• Unseasoned wood; or
• Paper products, cardboard, plywood, or particle board. (The
prohibition against burning these materials does not prohibit
the use of fire starters made from paper, cardboard, saw dust,
wax or similar substances for the purpose of starting a fire.)
The burning of any of these materials can result in the
release of toxic fumes, or render the heater ineffective and
cause smoke. Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to start or
"freshen-up" the fire. Always keep such liquids away from the
heater at all times.
