dining and living rooms are located. By locating the fireplace in this area, you will get the maximum benefit
of the heat it produces and will achieve the highest possible heating efficiency and comfort. The space
where you spend most of your time will be warmest, while bedrooms and basement (if there is one) will
stay cooler. In this way, you will burn less wood than with other forms of heating.
Although the fireplace may be able to heat the main living areas of your house to an adequate
temperature, we strongly recommend that you also have a conventional oil, gas or electric heating system
to provide backup heating.
Your success with zone heating will depend on several factors, including the correct sizing and location of
the fireplace, the size, layout and age of your home and your climate zone. Three-season vacation homes
can usually be heated with smaller fireplaces than houses that are heated all winter.

THE BENEFITS OF LOW EMISSIONS AND HIGH EFFICIENCY
The low smoke emissions produced by the special features inside the WFP-100 firebox mean that your
household will release up to 90 percent less smoke into the outside environment than if you used an older
conventional stove. 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, your fireplace releases all the heat energy from the wood instead of wasting it
as smoke up the chimney. Also, the features inside the firebox allow you to reduce the air supply to control
heat output, while maintaining clean and efficient flaming combustion, which boosts the efficient delivery of
heat to your home.
The emission control and advanced combustion features of your fireplace can only work properly if your fuel
is in the correct moisture content range of 15% to 20%. See Section 3: Fuel of this manual for suggestions
on preparing fuel wood and judging its moisture.
2.4 THE HEARTHSTONE COMMITMENT TO YOU AND THE ENVIRONMENT
The HEARTHSTONE team is committed to protecting the environment, so we do everything we can to use
only materials in our products that will have no lasting negative impact on the environment.
2.4.1 WHAT IS YOUR NEW FIREPLACE MADE OF?
The body of your fireplace, which is most of its weight, is carbon steel. Should it ever become necessary
many years in the future, almost the entire fireplace can be recycled into new products, thus eliminating
the need to mine new materials.
The paint coating on your fireplace 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 C-Cast baffle is made of an aluminosilicate fibre material that is compressed with a binder to form a
rigid board. C-Cast can withstand temperatures above 2,000 °F. It is not considered hazardous waste.
Disposal at a landfill is recommended.
Moulded refractory bricks are mainly composed of silicon dioxide, also known as silica, a product
processed from a mined mineral. It is most commonly found in nature in the form of sand and clay.
Disposal at a landfill is recommended. The steel mesh contained in some refractory bricks can be
recycled.
The door and glass gaskets are fibreglass which is spun from melted sand. Black gaskets have been
dipped into a solvent-free solution. Disposal at a landfill is recommended.
