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
FULLY CLOSED. OPERATION WITH THE DOOR PARTIALLY
OPEN MAY RESULT IN OVER-FIRING. IF THE DOOR
IS LEFT PARTIALLY OPEN, GAS AND FLAME MAY BE
DRAWN OUT OF THE STOVE CREATING SAFETY RISKS
FROM BOTH FIRE AND SMOKE.
5.0 Operation
Please read the following section before building the first
fire in your new Jøtul F 45 V2.
5.1 Combustion Efficiency
The Jøtul F 45 V2has an EPA tested High Heating Value
(HHV) efficiency rate of 71.0%. There are aspects of
efficiency, however, 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 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
-to-low burn rates.
The location of the stove can have a significant effect on
heating efficiency, primarily in regard to heat distribution.
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 45 V2to CSA B414.1-10 resulted in a carbon
monoxide emission rate of 1.48 grams per minute. Most
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 45 V2is 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 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 recommend 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.
BURN UNTREATED WOOD ONLY. 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 demolition debris;
• Railroad ties or pressure-treated wood;
• Manure or animal remains;
• Lawn clippings or yard waste;
• Salt water driftwood or other previously salt-water;
saturated materials;
• Unseasoned wood;
• Colored paper, 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.)
• Burning of any of the materials listed above can result in
the release of toxic fumes, cause smoke,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.
