1.4 Materials
The body of this stove, which is most of its weight, is carbon steel. Should it ever become
necessary many years in the future, almost the entire stove can be recycled into new products,
thus eliminating the need to mine new materials.
The paint coating on the stove is very thin. Its VOC content (Volatile Organic Compounds) is
very low. VOCs can be responsible for smog, so all the paint used during the manufacturing
process meets the latest air quality requirements regarding VOC reduction or elimination.
The air tubes are stainless steel, which can also be recycled.
The baffle is made of vermiculite compressed with a binder to form a rigid board. Vermiculite
can withstand temperatures above 2,000°F. It is not considered hazardous waste. Disposal at a
waste management center is recommended.
The firebrick is made of pumice, a volcanic rock, and cement. Disposal at a waste management
center is recommended.
The door and glass gaskets are fibreglass which is spun from melted sand. Black gaskets are
dipped into a solvent-free solution. Disposal at a waste management center is recommended.
The door glass is a 5/32" (4 mm) thick ceramic material that contains no toxic chemicals. It is
made of natural raw materials such as sand and quartz that are combined in such a way to form
a high temperature glass. Ceramic glass cannot be recycled in the same way as normal glass, so
it should not be disposed of with regular household products. Disposal at a waste management
center is recommended.
1.5 Zone Heating
This stove is a space heater, which means it is intended to heat the area it is installed in, as well
as spaces that connect to that area, although to a lower temperature. This is called zone heating
and it is an increasingly popular way to heat homes or spaces within homes.
Zone heating can be used to supplement another heating system by heating a particular space
within a home, such as a basement, a family room or an addition that lacks another heat source.
ENGLISH
Houses of moderate size and relatively new construction can be heated with a properly sized
and located wood stove. Whole house zone heating works best when the stove is in the part of
the house where the family spends most of its time. This is normally the main living area where
the kitchen, dining and living rooms are located.
Locating the stove in this area will give the maximum benefit of the heat it produces and will
achieve the highest possible heating efficiency and comfort. The space where the most time is
spent will be warmest, while bedrooms and basement (if there is one) will stay cooler. In this
way, less wood is burnt than with other forms of heating.
Although the stove may be able to heat the main living areas of the house to an adequate
temperature, it is strongly recommended to also have a conventional oil, gas or electric heating
system to provide backup heating.
Installation and Operation Manual - HES 240
Page 11
The success of zone heating will depend on several factors, including the correct sizing and
location of the stove, the size, layout and age of the home and the climate zone. Three-season
vacation homes can usually be heated with smaller stoves than houses that are heated all winter.
1.6 Emissions and Efficiency
The low smoke emissions produced by the special features inside this stove firebox mean that
the household will release up to 90% less smoke into the outside environment than if an older
conventional stove was used. But there is more to the emission control technologies than
protecting the environment.
The smoke released from wood when it is heated contains about half of the energy content of
the fuel. By burning the wood completely, this stove releases all the heat energy from the wood
instead of wasting it as smoke up the chimney. Also, the features inside the firebox allow control
of the air supply meaning controlling the heat output, while maintaining clean and efficient
flaming combustion, which boosts the efficient delivery of heat to the home.
ENGLISH
The emission control and advanced combustion features of this stove can only work properly
if the fuel used is in the correct moisture content range of 15% to 20%. Refer to the following
section for suggestions on preparing fuelwood and judging its moisture.
3. Fuel
Good firewood has been cut to the correct length for the stove, split to a range of sizes and
stacked outside to air dry until its moisture content is down to 15% to 20%.
DO NOT BURN:
• GARBAGE;
• LAWN CLIPPINGS OR YARD WASTE;
• MATERIALS CONTAINING RUBBER,
INCLUDING TIRES;
• MATERIALS CONTAINING PLASTIC;
• WASTE PETROLEUM PRODUCTS, PAINTS
OR PAINT THINNERS, OR ASPHALT
PRODUCTS;
• MATERIALS CONTAINING ASBESTOS;
• CONSTRUCTION OR DEMOLITION DEBRIS;
• RAILROAD TIES OR PRESSURE-TREATED
WOOD;
• MANURE OR ANIMAL REMAINS;
BURNING THESE MATERIALS MAY RESULT IN THE RELEASE OF TOXIC FUMES OR
RENDER THE HEATER INEFFECTIVE AND CAUSE SMOKE.
• 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 AND
SIMILAR SUBSTANCES FOR THE PURPOSE
OF STARTING A FIRE IN AN AFFECTED
WOOD HEATER.
1.7 Tree Species
The tree species the firewood is produced from is less important than its moisture content. The
main difference in firewood from various tree species is the density of the wood. Hardwoods are
denser than softwoods.
Homeowners with access to both hardwood and softwood use both types for different purposes.
Page 12
Installation and Operation Manual - HES 240
Softer woods make good fuel for mild weather in spring and fall because they light quickly
and produce less heat. Softwoods are not as dense as hardwoods so a given volume of wood
contains less energy. Using softwoods avoids overheating the house, which can be a common
problem with wood heating in moderate weather. Harder woods are best for colder winter
weather when more heat and longer burn cycles are desirable.
Note that hardwood trees like oak, maple, ash and beech are slower growing are longer lived
than softer woods like poplar and birch. That makes hardwood trees more valuable. The advice
that only hardwoods are good to burn is outdated. Old, leaky cast iron stoves wouldn’t hold a
fire overnight unless they were fed large pieces of hardwood.
1.8 Log Length
Logs should be cut at least 1" (25 mm) shorter than the firebox so they fit
in easily. Pieces that are even slightly too long makes loading the stove very
difficult. The most common standard length of firewood is 16" (400 mm).
ENGLISH
1.9 Log Size
Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry enough
to burn. Even when dried, unsplit logs are difficult to ignite because they don’t have the sharp
edges where the flames catch first.
Wood should be split to a range of sizes, from about 3" to 6" (75 mm to 150 mm) in cross
section. Having a range of sizes makes starting and rekindling fire much easier.
1.10 Compressed Wood Logs
Compressed wood logs made of 100% compressed sawdust can be
burned with caution in the number of these logs burned at once. Do
not burn compressed logs made of wax impregnated sawdust or logs
with any chemical additives. Follow the manufacturer’s instructions
and warnings.
Installation and Operation Manual - HES 240
Page 13
1.11 Drying Time
Firewood that is not dry enough to burn is the cause of most complaints about wood burning
appliances. Continually burning green or unseasoned wood produces more creosote and involves
lack of heat and dirty glass door.
Firewood with a moisture content between 15% and 20% will allow the stove to produce its
highest possible efficiency.
Here are some facts to consider in estimating drying time:
− Firewood bought from a dealer is rarely
dry enough to burn, so it is advisable
to buy the wood in spring and dry it
yourself;
− Drying happens faster in dry weather
than in a damp climate;
ENGLISH
− Drying happens faster in warm summer
weather than in winter weather;
− Split pieces dry more quickly than
unsplit rounds;
− Softwoods like pine, spruce, poplar,
and aspen take less time to dry than
hardwoods. They can be dry enough to
burn after being stacked to air dry only for the summer months;
− Hardwoods like oak, maple and ash can take one, or even two years to dry fully, especially if the
pieces are big;
− Firewood dries more quickly when stacked outside in a location exposed to sun and wind; it takes
much longer to dry when stacked in a wood shed.
Use these guidelines to find out if the firewood is dry enough to burn:
− Cracks forms at the end of logs as they dry;
− The wood turns from white or cream colored to grey or yellow;
− Two pieces of wood struck together sounds hollow;
− Dry wood is much lighter in weight than wet wood,
− The face of a fresh cut feels warm and dry;
− The moisture content read by a moisture meter is between
15% to 20%.

4. Operating the Stove
This wood heater has a manufacturer-set minimum low burn rate that
must not be altered. It is against federal regulations to alter this setting or
otherwise operate this wood heater in a manner inconsistent with operating
instructions in this manual.
The installation of the following items is optional and should be completed before using the
stove :
• Install the blower (see «Appendix 3: Optional Blower Installation»)
• Install the thermodisc (see «Appendix 4: Optional Thermodisc Installation»)
• Install the fresh air intake (see «Appendix 1: Optional Fresh Air Intake Kit Installation»)
1.12 The Use of a Fire Screen
This stove has been tested for use with an open door in conjunction with a fire screen, sold
separately. The fire screen must be properly secured on the stove to avoid any risk of sparks
damaging the flooring. When the fire screen is in use, do not leave the stove unattended to
respond promptly in the event of smoke spillage into the room. Potential causes of smoke
spillage are described in Section «9. The Venting System» of this manual. See «Appendix 2:
Optional Fire Screen Installation» for installation instructions.
OPERATING THE STOVE WITH A FIRE SCREEN INCREASES POSSIBILITIES OF
GENERATING CARBON MONOXIDE. CARBON MONOXIDE IS AN ODOURLESS GAS
THAT IS HIGHLY TOXIC WHICH CAN CAUSE DEATH AT HIGH CONCENTRATION IN AIR.
INSTALLATION OF A CARBON MONOXIDE DETECTOR IS HIGHLY RECOMMENDED.
1.13 Blower Operation
It is possible to install a blower on this stove. The blower is
optional and is sold separately. See «Appendix 8: Exploded
Diagram and Parts List» for genuine part number.
The blower is installed on the back of the stove to increase
the airflow through the heat exchanger and improve hot air
circulation in the room. When used regularly, the blower can
provide a small increase in efficiency, up to 2%. However,
the use of a blower should not be used as a way to gain
more output from a stove that is undersized for the space
it is intended to heat.
ENGLISH
Airflow with a blower
Installation and Operation Manual - HES 240
Ensure the blower power cord is not in
contact with any surface of the stove to
prevent electrical shock or fire damage.
Do not run the power cord underneath the
stove.
Page 15
The blower has a variable speed control that can be adjusted
HI
LO
in three different positions; either from high (HI) to low (LO) or
closed (OFF).
Allow the stove to reach operating temperature (approximately
one hour) before turning on the blower, since increased airflow
from the blower will remove heat and affect the start up
combustion efficiency.
It is possible to add a heat sensor, sold separately, to the
blower. When the blower is on (position between HI and LO),
the heat sensor will make the blower start automatically when
the stove is hot enough and will stop it when the stove has
cooled down. Therefore, the blower speed control can be left
at the desired setting.

5. Burning Wood Efficiently
1.14 First Use
Two things happen when burning the first few fires; the paint cures and the internal components are
conditioned. As the paint cures, some of the chemicals vaporize. The vapors are not poisonous,
but they smell bad. Fresh paint fumes can also trigger false alarms in smoke detectors. When
lighting the heater for the first few times, it may be wise to open doors and windows to ventilate
the house.
Burn two or three small fires to begin the curing and conditioning process. Then build bigger
and hotter fires until there is no longer paint smell from the stove. As hotter and hotter fires are
burned, more of the painted surfaces reach the curing temperature of the paint. The smell of
curing paint does not disappear until one or two very hot fires have been burned.
1.15 Lighting Fires
Each person heating with wood develops its own favorite way to light fires. Regardless of the
method chosen, the goal should be to have a hot fire burning, quickly. A fire that ignites fast
produces less smoke and deposits less creosote in the chimney.
Never use gasoline, gasoline-type lantern fuel (naphtha), fuel oil, motor oil,
kerosene, charcoal lighter fluid, or similar liquids or aerosols to start or
‘freshen up’ a fire in this wood stove. Keep all such liquids well away from
the stove while it is in use.
Here are three popular and effective ways to ignite wood fires.
1.15.1 Conventional Method
The conventional method to build a wood fire is to crumple 5 to 10 sheets
of newspaper and place them into the firebox and hold them in place with
ten pieces of kindling wood. The kindling should be placed on and behind
the newspaper.
Page 16
Installation and Operation Manual - HES 240
Then add two or three small pieces of firewood. Open the air intake control completely and ignite
the newspaper. Leave the door slightly ajar. Once the fire has ignited, the door can be closed
with the air control still fully open. When the kindling is almost completely burned, standard
firewood pieces can be added.
Do not leave the heater unattended when the door is slightly open. Always close and latch
the door after the fire ignites.
1.15.2 The Top Down Method
This method is the opposite of the conventional method and only works properly if well-seasoned
wood is used.
Place three or four small, split, dry logs in the firebox. Arrange the kindling wood on the logs in
two layers at right angles and place a dozen finely split kindling on the second row.
It is possible to use ragged paper but it may not hold in place since it tends to roll while it is
burning. The best is to wrap a sheet on itself, grab the ends of the roll and make a knot. Use
four or five sheets of paper tied together and put them on top and around the kindling. Open the
air intake control completely, ignite the paper and close the door.
The top down fire method has two advantages over the traditional method: first, the fire does
not collapse on itself, and it is not necessary to add wood gradually since the combustion
chamber is full before the fire is lit.
ENGLISH
1.15.3 Two Parallel Logs Method
Two spit logs are placed in the firebox with a few sheets of twisted newspapers in between the
logs. Fine kindling is added across the two logs and some larger kindling across those, log cabin
style. Newspaper is lit.
1.15.4 Using Fire Starters
Commercial fire starters can be used instead of a newspaper. Some of these starters are made
of sawdust and wax and others are made of specialized flammable solid chemicals. Always
follow the package directions when using. Gel starters can also be used, but only to light a fire,
in a cold combustion chamber without hot embers inside.
1.16 Combustion Cycles
Wood heating with a space heater is very different than other forms of heating. There will be
temperature variations in different parts of the house and there will be temperature variations
throughout day and night. This is normal, and for experienced wood burners these are advantages
of zone heating wood burning.
Wood heaters don’t have a steady heat output. It is normal for the temperature to rise after
a new load of wood is ignited and for its temperature to gradually decrease throughout the
burning cycle. This increasing and decreasing temperature can be matched with the household
routines. For example, the temperature in the area can be cooler when the household is active,
and it can be warmer when it is inactive. Wood burns best in cycles. A cycle starts when a new
load of wood is ignited by hot coals and ends when that load has been consumed down to a
bed of charcoal about the same size as it was when the wood was loaded.
