2.3 ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU
Your new Stratford 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.

Stratford Fireplace Installation and Operation Manual
_____________________________________________________________________ 13
2.4 THE BENEFITS OF LOW EMISSIONS AND HIGH EFFICIENCY
The low smoke emissions produced by the special features inside the Stratford 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 percent. See Section 3: Fuel of this
manual for suggestions on preparing fuelwood and judging its moisture.
2.5 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.
2.5.1 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 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.

3.1 MATERIALS THAT SHOULD NOT BE BURNED
•GARBAGE OF ANY KIND,
•COAL OR CHARCOAL,
•TREATED, PAINTED OR COATED WOOD,
•PLYWOOD OR PARTICLE BOARD,
•FINE PAPER, COLORED PAPER OR CARDBOARD,
•SALT WATER DRIFTWOOD,
•MANUFACTURED LOGS CONTAINING WAX OR CHEMICAL ADDITIVES,
•RAILROAD TIES,
•LIQUIDS SUCH AS KEROSENE OR DIESEL FUEL TO START A FIRE.
WARNING: 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 WARNINGS AND
CAUTIONS MARKINGS ON PACKAGING.
3.2 HOW TO PREPARE OR BUY GOOD FIREWOOD
3.2.1 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 per cent.
3.2.2 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.

Stratford Fireplace Installation and Operation Manual
_____________________________________________________________________ 15
3.2.3 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 most common standard length
of firewood is 16” (400 mm).
The pieces should be a consistent length, with a maximum of 1” (25 mm) variation from piece to
piece.
3.2.4 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.

Stratford Fireplace Installation and Operation Manual
16_____________________________________________________________________
3.2.5 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
•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
•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 dries more 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
•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

Stratford Fireplace Installation and Operation Manual
_____________________________________________________________________ 17
3.2.6 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.
You could buy a wood moisture meter to test
your firewood.
3.3 MANUFACTURED LOGS
Do not burn manufactured logs made of wax
impregnated sawdust or logs with any chemical
additives. Manufactured logs made of 100%
compressed sawdust can be burned, but be
careful burning too much of these logs at the
same time. Start with one manufactured log
and see how the fireplace reacts. Never use
more than two manufactured logs at a time.

Stratford Fireplace Installation and Operation Manual
18_____________________________________________________________________
4OPERATING YOUR FIREPLACE
4.1 THE USE OF A FIRESCREEN
This fireplace has been tested for use with an open door in conjunction with a firescreen
(AC01560, sold separately). Make sure the firescreen is properly secured on the fireplace to avoid
any risk of sparks damaging your flooring. When the firescreen is in use, do not leave the fireplace
unattended so that you can respond promptly in the event of smoke spillage into the room.
Potential causes of smoke spillage are described in Section 8: The Venting System of this manual.
See Appendix 5: Installing the Firescreen (AC01560) for installation instructions.
OPERATING WITH THE FIRESCREEN INCREASES THE POSSIBILITY OF GENERATING CARBON
MONOXIDE. CARBON MONOXIDE IS AN ODOURLESS GAS THAT IS HIGHLY TOXIC AND WHICH
CAN CAUSE DEATH AT HIGH CONCENTRATION IN AIR.
4.2 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.
4.3 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.

Stratford Fireplace Installation and Operation Manual
_____________________________________________________________________ 19
4.3.1 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 or 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.
A conventional kindling fire with paper
under finely split wood.
DO NOT LEAVE THE FIREPLACE UNATTENDED WHEN THE DOOR IS SLIGHTLY OPENED. ALWAYS
CLOSE AND LATCH THE DOOR AFTER THE FIRE IGNITES.
After the kindling fire has mostly burned, you can add standard firewood pieces until you have a
fire of the right size for the conditions.
CAUTION: PLACE THE WOOD LOGS FAR ENOUGH FROM THE GLASS TO ALLOW PROPER PRIMARY
AIR FLOW
4.3.2 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 is not necessary to build up the fire
gradually because the firebox is loaded before the fire is lit. A top down fire can provide up to two
hours of heating or more. The top down method only works properly if the wood is well-seasoned.
Start by placing three or four full-sized split pieces of dry firewood in the firebox. Next, place 4 or 5
more finely split pieces of firewood (2” to 3” [50 mm to 75 mm] in dia.) on the base logs at right
angles (log cabin style). Now place about 10 pieces of finely split kindling on the second layer at
right angles.
The fire is topped with about 5 sheets of newspaper. You can just bunch them up and stuff them
in between the kindling and the underside of the baffle. Or you can make newspaper knots by
rolling up single sheets corner to corner and tying a knot in them. The advantage of knots is that
they don’t roll off the fire as they burn. Light the newspaper and watch as the fire burns from top
to bottom.

4.3.3 TWO PARALLEL LOGS
Place two spit logs in the firebox. Place a few sheets of twisted newspaper between the logs. Now
place some fine kindling across the two logs and some larger kindling across those, log cabin style.
Light the newspaper.
4.3.4 USING FIRE STARTERS
Many people like to use commercial fire starters instead of newspaper. Some of these starters are
made of sawdust and wax and others are specialized flammable solid chemicals. Follow the
package directions for use.
Gel starter may be used but only if there are no hot embers present. Use only in a cold firebox to
start a fire.
DO NOT USE FLAMMABLE LIQUIDS SUCH AS GASOLINE, NAPHTHA, FUEL OIL, MOTOR OIL, OR
AEROSOLS TO START OR REKINDLE THE FIRE.
4.4 MAINTAINING WOOD FIRES
4.4.1 GENERAL ADVICE
Wood heating with a space heater is very different than other forms of heating. There will be
variations in the temperature in different parts of the house and there will be variations in
temperature throughout the day and night. This is normal, and for experienced wood burners
these are advantages of zone heating with wood.
Do not expect steady heat output from your fireplace. It is normal for its surface temperature to
rise after a new load of wood is ignited and for its temperature to gradually decline as the fire
progresses. This rising and falling of temperature can be matched to your household routines. For
example, the area temperature can be cooler when you are active, such as when doing housework
or cooking, and it can be warmer when you are inactive, such as when reading or watching
television.
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. Do not attempt to produce a steady heat output by placing a single log on
the fire at regular intervals. Always place at least three, and preferably more, pieces on the fire at
a time so that the heat radiated from one piece helps to ignite the pieces next to it. Each load of
wood should provide several hours of heating. The size of each load can be matched to the
amount of heat needed.
When you burn in cycles, you rarely need to open the fireplace’s loading door while the wood is
flaming. This is an advantage because there is more chance that smoke will leak from the fireplace
when the door is opened as a full fire is burning.
IF YOU MUST OPEN THE DOOR WHILE THE FUEL IS FLAMING, OPEN THE AIR CONTROL FULLY FOR
A FEW MINUTES, THEN UNLATCH AND OPEN THE DOOR SLOWLY.
