2.5 Zone Heating and How to make it work for you
Your new WATERLOO wood fireplace 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 family room or an addition that lacks another heat source.
Houses of moderate size and relatively new construction can be heated with a properly sized and located
wood fireplace. Whole house zone heating works best when the fireplace is located 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. 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.
2.6 The Benefits of Low Emissions and High Efficiency
The low smoke emissions produced by the special features inside the WATERLOO 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.
2.7 The SBI Commitment to You and the Environment
The SBI 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.

16 FP15 & FP15A Waterloo - Installation and Operation Manual
2.7.1 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.
The door glass is a 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 your
regular household products. Disposal at a landfill is recommended.

3.1 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%.

FP15 & FP15A Waterloo - Installation and Operation Manual 17
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.
3.1.3 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 make loading the fireplace very difficult. The log length recommended for your fireplace is
16"(406mm).
The pieces should be a consistent length, with a
maximum of 1"(25 mm) variation from piece to
piece.
3.1.4 Piece 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 first catch. Logs as small as 3” (75 mm) should be split to encourage drying.
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 fires much easier. Often, the firewood purchased from
commercial suppliers is not split finely enough for convenient stoking. It is sometimes advisable to resplit
the wood before stacking to dry.

18 FP15 & FP15A Waterloo - Installation and Operation Manual
3.1.5 How to Dry Firewood
Firewood that is not dry enough to burn is the cause of most complaints about wood fireplaces. Continually
burning green or unseasoned wood produces more creosote and involves lack of heat and dirty glass door.
See Section 5: Maintaining your wood heating system for concerns about creosote.
Here are some things to consider in estimating drying time:
•
Firewood takes a long time to dry.
•Small pieces dry more quickly than large pieces.
•Split pieces dry
more quickly than unsplit
rounds.
•
Softwoods take less time to dry than
hardwoods.
•Softwoods like pine, spruce, and poplar/aspen
can be dry enough to burn after being stacked
in the open for only 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 that is ready to burn has a moisture
content between 15% and 20% by weight and
will allow your fireplace to produce its highest
possible efficiency.
•
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
damp, maritime climates.
•Drying happens faster in warm summer weather
than in winter weather.
•Firewood dries mo
re quickly when stacked in
the open where it is exposed to sun and wind; it
takes much longer to dry when stacked in a
wood shed.
3.1.6 Judging Firewood Moisture Content
You can find out if some firewood is dry enough to burn by using these guidelines:
•cracks form at the ends of logs as they dry,
•as it dries in the sun, the wood turns from white or cream colored to grey or yellow,
•bang two pieces of wood together; seasoned wood sounds hollow and wet wood sounds dull,
•dry wood is much lighter in weight than wet wood,
•split a piece, and if the fresh face feels warm and dry it is dry enough to burn; if it feels damp, it is too
wet,
•burn a piece; wet wood hisses and sizzles in the fire and dry wood does not.

FP15 & FP15A Waterloo - Installation and Operation Manual 19
You could buy a wood moisture meter to test your
firewood.
3.2 Manufactured Logs
Manufactured logs made of 100% wood residues
can be burn in your fireplace. However, they must
be used carefully. Therefore, you cannot place a
large quantity of such logs into your fireplace.
Manufactured logs typically release a much larger
heat output over a short period of time. Start with
one log and see how the fireplace reacts. You can
increase the number of logs burned at a time to a
maximum of three. Burning more than three
manufactured logs at one time can overheat and
damage your stove.
CAUTION
•
DO NOT BURN ANY MANUFACTURED LOGS CONTAINING CHEMICAL ADDITIVES. YOU MAY
OVERHEAT YOUR FIREPLACE, THEREFORE CAUSING A FIRE HAZARD AND VOIDING YOUR
WARRANTY.
•DO NOT POKE OR STIR THE LOGS WHILE THEY ARE BURNING.
•USE ONLY FIRELOGS THAT HAVE BEEN TESTED FOR USE IN FIREPLACES (SEE ULC/ORD-C127,
COMPOSITE FIRELOGS) AND PRIOR TO USE, REFER TO FIRELOG WARNI
NGS AND CAUTIONS
MARKINGS ON PACKAGING.

4OPERATING YOUR FIREPLACE
4.1 Your First Fires
Two things will happen as you burn your first few fires: the paint cures and the internal components of the
fireplace are conditioned.
As the paint cures, some of the chemicals vaporize. The vapors are not poisonous, but they do smell bad.
Fresh paint fumes can also cause false alarms in smoke detectors. So, when you first light your fireplace, be
prepared by opening doors and/or windows to ventilate the house. As you burn hotter and hotter fires,
more of the painted surfaces reach the curing temperature of the paint. The smell of curing paint does not
disappear until you have burned one or two very hot fires.
Burn one or two small fires to begin the curing and conditioning process. Then build bigger and hotter fires
until there is no longer any paint smell from the fireplace. Once the paint smell disappears, your fireplace is
ready for serious heating.
4.2 Lighting Fires
Each person who heats with wood develops their own favorite way to light fires. Whatever method you
choose, your goal should be to get a hot fire burning quickly. A fire that starts fast produces less smoke and
deposits less creosote in the chimney. Here are three popular and effective ways to start wood fires.
4.2.1 BEST PRACTICE: The Top Down Fire
The top down fire-starting method solves two problems with the conventional method: first, it does not
collapse and smother itself as it burns; and second, it’s cleaner. The top down method only works properly
if the wood is well-seasoned.
Start by crisscrossing around 10 finely split and dry kindling (0.5 to 1 in) leaving air space between the
pieces. Then put at least 5 news paper sheets to the top of the pieces. The best way to have your ignition
clean and environmentally friendly is to roll the news papers to make a long cylinder, then to make 2 knots
with it. The goal is to have the news papers as compact as possible to make it burn slowly. After the ignition
of the news paper, let the door open of 1 inch for 5-10 minutes. The air control should be open.
When you have a small coal bed, it’s the time to crisscross three or four medium-sized split pieces (2-3 in)
of dry firewood in the firebox. You can close the door as soon as you loaded the pieces. Let burn until you
have a good coal bed. You are now ready for the main load.
4.2.2 Conventional Fire Starting
The conventional way to build a wood fire is to bunch up 5 to 10
sheets of plain newspaper and place them in the firebox. Next,
place 10 o
r so pieces of fine kindling on the newspaper. This
kindling should be very thin; less than 1” (25 mm). Next, place
some larger kindling pieces on the fine kindling. Open the air
control fully and light the newspaper. If you have a tall, straight
venting system you should be able to close the door immediately
and the fire will ignite. Once the fire has ignited, close the door
and leave the air control fully open.
