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.
The door glass is a 5 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
your regular household products. Disposal at a landfill is recommended.

CAUTION
•
DO NOT BURN SCRAP OR GARBAGE, TREATED WOOD OR WOOD SUCH AS DRIFTWOOD
FROM THE OCEAN WHICH HAS BEEN EXPOSED TO SALT OR OTHER CHEMICALS. SALT OR
CHEMICALS CAN CORRODE THE FIREBOX AND CHIMNEY. DO NOT BURN LARGE AMOUNTS
OF PAPER, CARDBOARD, TREE BRANCHES OR BUILDING CONSTRUCTION MATERIALS.
INTENSE FIRING WITH THESE MATERIALS MAY OVERHEAT THE FIREPLACE, CAUSING
DAMAGE TO THE UNIT, A HOME FIRE OR EVEN POSSIBLY IGNITING A CHIMNEY FIRE IF THE
CHIMNEY IS CREOSOTED.
•
DO NOT OVER FIRE THIS HEATER OVER FIRING CAN RESULT IN A SAFETY HAZARD AND CAN
PERMANENTLY DAMAGE THE FIREPLACE AND CHIMNEY.

HOW TO PREPARE OR BUY GOOD FIREWOOD
3.1.1 WHAT IS GOOD FIREWOOD?
Good firewood has been cut to the correct length for the fireplace, split to a range of sizes and stacked in
the open until its moisture content is reduced to 15% to 20%.
3.1.2 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. People who live in the coldest regions of North America usually have only spruce, birch and
poplar, other low-density species to burn and yet they can heat their homes successfully.
Homeowners with access to both hardwood and softwood fuel sometimes use both types for different
purposes. For example, softer woods make good fuel for relatively 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 and 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. That is no longer true. You can successfully heat your home by using the less
desirable tree species and give the forest a break at the same time.
