2.3 The Benefits of Low Emissions and High Efficiency
The low smoke emissions produced by the special features inside the Stratford CF firebox mean that your
household will release up to 90 percent less smoke into the outside environment than if you used an older
conventional zero clearance wood inbuilt. 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 zero clearance wood inbuilt releases all the heat energy from the wood
instead of wasting it as smoke up the flue system. 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 zero clearance wood inbuilt can only work
properly if your fuel is in the correct moisture content range of 11 to 16 percent. See Section 3: Fuel of this
manual for suggestions on preparing fuelwood and judging its moisture.
2.4 Osburn's Commitment to You and the Environment
The Osburn 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 Zero clearance wood inbuilt Made Of?
The body of your wood inbuilt, which is most of its weight, is carbon steel. Should it ever become necessary
many years in the future, almost the entire wood inbuilt can be recycled into new products, thus
eliminating the need to mine new materials.
The paint coating on your wood inbuilt is very thin. Its VOC content (Volatile Organic Components) is very
low. VOCs can be responsible for smog, so all the paint used during the manufacturing process meets the
latest air quality requirements with regards to 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 1 093 °C (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.
The door glass is a 5 mm thick ceramic material that contains no toxic chemicals. It is basically made of raw
earth materials such as sand and quartz that are combined in such a way to form a glass at high
temperatures. Ceramic glass will not re-melt in the same way as normal glass, so it should not be recycled
with your regular household products. Disposal at a landfill is recommended.
