5. Operation
Please read the following section completely before building a
fire in your new Jøtul F 500 V3.
DO NOT OVERFIRE THIS HEATER.
THE MAXIMUM RECCOMENDED OPERATING
TEMPERATURE OF THE COMBUSTOR IS 1600°F (870°C).
DAMAGE CAN OCCUR TO THE COMBUSTOR IF IT
EXCEEDS 1750°F (954°C) FOR EVEN BRIEF PERIODS OF
TIME.
5.1 Combustion Efficiency
The Jøtul F 500 V3 has an EPA test High Heating Value
(HHV) efficiency rate of 78.4%. 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, 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 also have a significant effect
on heating efficiency, primarily in regard to distribution of the
heat. For example, a wood heater centrally located in an open
living area, will likely provide better circulation of heat than will
room adjacent to the larger living area.
a stove located in a
5.2 Minimize Carbon Monoxide
Emissions
Testing the F 500 V3 to CSA B415.1-10 resulted in a carbon
monoxide emission rate of .50 grams per minute. There are
properties related to CO generation that you should be
aware of. Most means of combustion produce CO, including
wood fire. You can greatly reduce CO levels by maintaining
a well-established fire and avoiding operation that produces
a smouldering, smoky fire. We highly recommend that a CO
monitor (detector) be installed in the same room as the stove.
The monitor should be located as far away as possible from the
stove to avoid alerts when the doors are opened.
5.3 Wood Fuel and Performance
Use dry wood.
The F 500 V3 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 of the stove's low end efficiency
strength.
A seasoned log will have many check marks (cracks) through
the ends and be lighter than an unseasoned log which will show
few or no check marks.
We recommend using a moisture meter that incorporates
probes to determine the moisture content of your wood.
Meters are available at your dealer or local hardware store. For
purposes of home heating, your fuel should have a moisture
content between 12 - 20% on the meter gauge. Wood with
higher moisture content will burn, however, very inefficiently.
Most of its heat value will be lost through evaporation, 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 and weak draft strengh. 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 demolitioin 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, junk mail, cardboard, plywood, or particle board.
(The prohibition against burning these materials does not include
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
catalytic combustor permanently damaged and ineffective.
