5.0 Operation
Please read the following section completely before building
a fire in your new Jøtul F 602 CB.
5.1 Combustion Efficiency
The Jøtul F 602 CB has an EPA tested High Heating Value
(HHV) efficiency rate of 70.06. 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 to the living area
as a result of the energy expended to evaporate the excess
fuel moisture in order for the wood to burn. Operational
habits - such as not building a robust kindling fire to readily
ignite the larger fuel pieces - can result in an inefficient,
smouldering 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 regard 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 Minimize Carbon Monoxide Emissions
Testing the F 602 CB to CSA B414.1-10 resulted in a carbon
monoxide emission rate of 64.64 grams per hour. There are,
however, aspects of CO generation 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
minimize 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 602 CB 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 than 2 years will burn too quickly to take advantage
Check Moisture Content
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.
NOTE: Avoid letting logs rest directly on the glass panel. The
logs should be spaced off of the glass enough to allow for
proper air flow within the firebox.

5.4 Air Flow and Control

Your Jøtul F 602 CB is designed to support efficient
combustion and heat transfer by directing air through the
stove in two separate channels; Primary and Secondary.
Primary air is manually regulated by a sliding valve located
in the load door. The valve position controls the volume
of primary air entering the firebox and thereby affects
fire intensity, heat output and burn time. Primary air is
directed to the main body of the fire through that air inlet.
