2.4 Materials
The body of this stove, which is most of its weight, is carbon steel. Should it ever become
necessary many years in the future, almost the entire stove can be recycled into new products,
thus eliminating the need to mine new materials.
The paint coating on the stove 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 baffle is made of 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 waste management center is recommended.
ENGLISH
The firebrick is 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 waste management center is recommended.
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 waste management center is
recommended.
The door glass is a 5/32" (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 regular household products. Disposal at a waste management
center is recommended.
2.5 Zone Heating
This stove 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, a 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 stove. Whole house zone heating works best when the stove is 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.
Locating the stove in this area will give the maximum benefit of the heat it produces and will
achieve the highest possible heating efficiency and comfort. The space where the most time is
spent will be warmest, while bedrooms and basement (if there is one) will stay cooler. In this
way, less wood is burnt than with other forms of heating.
Although the stove may be able to heat the main living areas of the house to an adequate
temperature, it is strongly recommended to also have a conventional oil, gas or electric heating
system to provide backup heating.
Page 14
Installation and Operation Manual - Gateway 3500
Page 15
The success of zone heating will depend on several factors, including the correct sizing and
location of the stove, the size, layout and age of your home and your climate zone. Three-season
vacation homes can usually be heated with smaller stoves than houses that are heated all winter.
2.6 Emissions and Efficiency
The low smoke emissions produced by the special features inside this stove firebox mean that
the household will release up to 90% less smoke into the outside environment than if an older
conventional stove was used. 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, this stove releases all the heat energy from the wood
instead of wasting it as smoke up the chimney. Also, the features inside the firebox allow control
of the air supply meaning controlling the heat output, while maintaining clean and efficient
flaming combustion, which boosts the efficient delivery of heat to the home.
The emission control and advanced combustion features of this stove can only work properly
if the fuel used is in the correct moisture content range of 15% to 20%. Refer to the following
section of suggestions on preparing fuelwood and judging its moisture.
3. Fuel
ENGLISH
Good firewood has been cut to the correct length for the stove, split to a range of sizes and
stacked in the open until its moisture content is down to 15% to 20%.
DO NOT BURN:
• GARBAGE;
• LAWN CLIPPINGS OR YARD WASTE;
• MATERIALS CONTAINING RUBBER,
INCLUDING TIRES;
• MATERIALS CONTAINING PLASTIC;
• WASTE PETROLEUM PRODUCTS, PAINTS
OR PAINT THINNERS, OR ASPHALT
PRODUCTS;
• MATERIALS CONTAINING ASBESTOS;
• CONSTRUCTION OR DEMOLITION DEBRIS;
• RAILROAD TIES OR PRESSURE-TREATED
WOOD;
• MANURE OR ANIMAL REMAINS;
BURNING THESE MATERIALS MAY RESULT IN THE RELEASE OF TOXIC FUMES OR
RENDER THE HEATER INEFFECTIVE AND CAUSE SMOKE.
• SALT WATER DRIFTWOOD OR OTHER
PREVIOUSLY SALT WATER SATURATED
MATERIALS;
• UNSEASONED WOOD; OR
• PAPER PRODUCTS, CARDBOARD,
PLYWOOD, OR PARTICLE BOARD. THE
PROHIBITION AGAINST BURNING THESE
MATERIALS DOES NOT PROHIBIT THE USE
OF FIRE STARTERS MADE FROM PAPER,
CARDBOARD, SAW DUST, WAX AND
SIMILAR SUBSTANCES FOR THE PURPOSE
OF STARTING A FIRE IN AN AFFECTED
WOOD HEATER.
3.1 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.
Homeowners with access to both hardwood and softwood use both types for different purposes.
Installation and Operation Manual - Gateway 3500
Page 15
Page 16
Softer woods make good fuel for 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.
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.
3.2 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 makes loading the stove very
difficult. The most common standard length of firewood is 16" (400 mm).
ENGLISH
3.3 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.
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.
3.4 Compressed Wood Logs
Compressed wood logs made of 100% compressed sawdust can be
burned with caution in the number of these logs burned at once. Do
not burn compressed logs made of wax impregnated sawdust or logs
with any chemical additives. Follow the manufacturer’s instructions
and warnings.
3.5 Drying Time
Firewood that is not dry enough to burn is the cause of most complaints about wood burning
appliances. Continually burning green or unseasoned wood produces more creosote and involves
lack of heat and dirty glass door.
Firewood with a moisture content between 15% and 20% will allow the stove to produce its
highest possible efficiency.
Page 16
Installation and Operation Manual - Gateway 3500
Page 17
Here are some facts to consider in estimating drying time:
− 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 a damp climate;
− Drying happens faster in warm summer
weather than in winter weather;
− Split pieces dry more quickly than
unsplit rounds;
− Softwoods like pine, spruce, poplar,
and aspen take less time to dry than
hardwoods. They can be dry enough to
burn after being stacked to air dry only for 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 outside in a location exposed to sun and wind; it takes
much longer to dry when stacked in a wood shed;.
ENGLISH
Firewood is dry enough to burn when:
− Cracks form at the end of logs;
− The wood turns from white or cream colored to grey or yellow;
− Two pieces of wood struck together sounds hollow;
− The face of a fresh cut feels warm and dry;
− The moisture content read by a moisture meter is between
15% to 20%.
4. Operating the Stove
This wood heater has a manufacturer-set minimum low burn rate that
must not be altered. It is against federal regulations to alter this setting or
otherwise operate this wood heater in a manner inconsistent with operating
instructions in this manual.
Before using the stove, the following steps should be completed :
• Install the leg kit (see «Appendix 1: Legs Installation») or the pedestal (see «Appendix 2: Pedestal
Installation» ).
• Install the overlay (see «Appendix 3: Door Overlay Installation»).
The following steps are optional
• Install the step top add on (see «Appendix 5: Optional Step Top Add On Installation»)
• Install the blower (See «Appendix 8: Optional Blower Installation»)
• Install the thermodisc (See «Appendix 9: Optional Thermodisc Installation»)
• Install the fresh air intake (see «Appendix 6: Optional Fresh Air Intake Kit Installation»)
Installation and Operation Manual - Gateway 3500
Page 17
Page 18
4.1 Blower Operation
HI
LO
A blower can be installed on this stove. It is optional and is sold separately. See «Appendix 12:
Exploded Diagram and Parts List» for genuine part number. The blower must be installed on the
back of the stove. See «Appendix 8: Optional Blower Installation» for instructions. The blower is
used to increase the airflow through the heat exchanger and improve hot air circulation in the
room.
When used regularly, the blower can provide a small increase
in efficiency, up to 2%. However, the use of a blower should
not be used as a way to gain more output from a stove that
is undersized for the space it is intended to heat.
Ensure the blower cord is not in contact with
any surface of the stove to prevent electrical
shock or fire damage. Do not run cord
ENGLISH
underneath the stove.
The blower has a variable speed control that can be adjusted in three
different positions; either from high (HI) to low (LO) or closed (OFF).
OFF
Allow the stove to reach operating temperature (approximately one hour)
before turning on the blower, since increased airflow from the blower will
remove heat and affect the start up combustion efficiency.
It is also possible to install a heat sensor that works with the blower. The thermodisc is optional
and is sold separately. The heat sensor must also be installed at the back of the stove. See
«Appendix 9: Optional Thermodisc Installation». When the blower is on (position between HI and
LO), the heat sensor will make the blower start automatically when the stove is hot enough and
will make it stop when the stove has cooled down. Therefore, the blower speed control can be
left at the desired setting.
4.2 The Use of a Fire Screen
This stove has been tested for use with an open door in conjunction with a fire screen, sold
separately. The fire screen must be properly secured on the stove to avoid any risk of sparks
damaging the flooring. When the fire screen is in use, do not leave the stove unattended to
respond promptly in the event of smoke spillage into the room. Potential causes of smoke
spillage are described in Section «9. The Venting System» of this manual. See «Appendix 7:
Optional Fire Screen Installation» for installation instructions.
Operating the stove with a fire screen increases possibilities of generating carbon monoxide. Carbon
monoxide is an odourless gas that is highly toxic which can cause death at high concentration in
air. Installation of a carbon monoxide detector is highly recommended.
5. Burning Wood Efficiently
5.1 First Use
Two things happen when burning the first few fires; the paint cures and the internal components are
conditioned. As the paint cures, some of the chemicals vaporize. The vapors are not poisonous,
but they smell bad. Fresh paint fumes can also trigger false alarms in smoke detectors.
Page 18
Installation and Operation Manual - Gateway 3500
Page 19
When lighting the heater for the first few times, it may be wise to open doors and windows to
ventilate the house.
Burn two or three small fires to begin the curing and conditioning process. Then build bigger
and hotter fires until there is no longer paint smell from the stove. As hotter and hotter fires are
burned, more of the painted surfaces reach the curing temperature of the paint. The smell of
curing paint does not disappear until one or two very hot fires have been burned.
5.2 Lighting Fires
Each person heating with wood develops its own favorite way to light fires. Regardless of the
method chosen, the goal should be to have a hot fire burning, quickly. A fire that ignites fast
produces less smoke and deposits less creosote in the chimney.
Never use gasoline, gasoline-type lantern fuel (naphtha), fuel oil, motor oil,
kerosene, charcoal lighter fluid, or similar liquids or aerosols to start or
‘freshen up’ a fire in this wood stove. Keep all such liquids well away from
the stove while it is in use.
Here are three popular and effective ways to ignite wood fires.
ENGLISH
5.2.1 Conventional Method
The conventional method to build a wood fire is to crumple 5 to 10 sheets
of newspaper and place them in the firebox and hold them in place
with ten pieces of kindling wood. The kindling should be placed on and
behind the newspaper. Then add two or three small pieces of firewood.
Open the air intake control completely and ignite the newspaper. Leave
the door slightly ajar.
Once the fire has ignited, the door can be closed with the air control still fully open. When the
kindling is almost completely burned, standard firewood pieces can be added.
Do not leave the heater unattended when the door is slightly open. Always close and latch
the door after the fire ignites.
5.2.2 The Top Down Method
This method is the opposite of the conventional method and only works properly if well-seasoned
wood is used. Place three or four small, split, dry logs in the firebox. Arrange the kindling wood
on the logs in two layers at right angles and place a dozen finely split kindling on the second
row. It is possible to use ragged paper but it may not hold in place since it tends to roll while it
is burning. The best is to wrap a sheet on itself, grab the ends of the roll and make a knot. Use
four or five sheets of paper tied together and put them on top and around the kindling.
Open the air intake control completely, ignite the paper and close the door.
The top down fire method has two advantages over the traditional method: first, the fire does
not collapse on itself, and it is not necessary to add wood gradually since the combustion
chamber is full before the fire is lit.
Installation and Operation Manual - Gateway 3500
Page 19
Page 20
5.2.3 Two Parallel Logs Method
Two spit logs are placed in the firebox with a few sheets of twisted newspapers in between the
logs. Fine kindling is added across the two logs and some larger kindling across those, log cabin
style. Newspaper is lit.
5.2.4 Using Fire Starters
Commercial fire starters can be used instead of a newspaper. Some of these starters are made
of sawdust and wax and others are made of specialized flammable solid chemicals. Always
follow the package directions when using.
Gel starters can also be used, but only to light a fire, in a cold combustion chamber without hot
embers inside.
5.3 Combustion Cycles
Wood heating with a space heater is very different than other forms of heating. There will be
ENGLISH
temperature variations in different parts of the house and there will be temperature variations
throughout day and night. This is normal, and for experienced wood burners these are advantages
of zone heating wood burning.
Wood heaters don’t have a steady heat output. It is normal for the temperature to rise after
a new load of wood is ignited and for its temperature to gradually decrease throughout the
burning cycle. This increasing and decreasing temperature can be matched with the household
routines. For example, the temperature in the area can be cooler when the household is active,
and it can be warmer when it is inactive.
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.
Trying to produce a steady heat output by placing a single log on the fire at regular intervals
is not recommended. 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 may vary depending on the
amount of heat required.
Burning in cycles means the loading door does not need to be opened while the wood is flaming.
This is an advantage since it is preventing smoke leaking from the heater when the door is
opened as a full fire is burning. This is especially true if the chimney is on the outside wall of the
house.
If the door must be opened while the fire is flaming, fully open air control for a few
minutes then open the door slowly.
5.4 Rekindling a Fire
When the temperature of the room is lower and all that remains is embers, it is time to reload.
Most of the remaining embers will be at the back of the firebox. Remove excess ash from the
front of the firebox and bring the embers forward before reloading. Place a new load of wood on,
and at the back of the embers. Open the air control completely and close the door.
Page 20
Installation and Operation Manual - Gateway 3500
Page 21
Raking the coals is useful for two reasons. First, it brings them near where most of the combustion
air enters the firebox. This will ignite the new load quickly. Secondly, the charcoal will not be
smothered by the new load of wood. When the embers are simply spread inside the combustion
chamber, the new load smoulder for a long time before igniting.
Close the air control only when the firebox is full of bright turbulent flames, the wood is charred,
and its edges are glowing.
The heater should not be left unattended during ignition and the
fire should not burn at full intensity for more than a few minutes.
When lighting a new load, the appliance produces a heat surge. This heat surge is pleasant
when the room temperature is cool but can be unpleasant when the room is already warm.
Therefore, it is best to let each load of wood burn completely so that the room cools down
before reloading.
ENGLISH
5.5 Removing Ashes
Ash should be removed from the firebox every two to three days of full-time heating. Ash
should not accumulate excessively in the firebox since it will affect the proper operation of the
appliance. The best time to remove ash is in the morning, after an overnight fire when the heater
is relatively cold, but there is still a little chimney draft to draw the ash dust into the heater and
prevent going out into the room.
Ashes should be placed in a tightly covered metal container. The container must be
placed on a non-combustible floor or on the ground well away from all combustible
materials. Ashes almost always contain live embers that can stay hot for days and
which release carbon monoxide gas. If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be kept in a closed metal container until
they are completely cooled. No other waste should be placed in this container.
NEVER STORE ASHES INDOORS OR IN A NON-METALLIC CONTAINER
CENDRES
ASHES
OR ON A WOODEN DECK.
5.6 Air Intake Control
Once the firewood, firebox and chimney are hot, air intake can be
reduced to achieve a steady burn.
As the air intake is reduced, the burn rate decreases. This has the
effect of distributing the thermal energy of the fuel over a longer
period of time. In addition, the flow rate of exhaust through the
appliance and flue pipe slows down, which increases the duration
of the energy transfer of the exhaust gases.
Installation and Operation Manual - Gateway 3500
Page 21
Page 22
As the air intake is reduced, the flame slows down. If the flames diminish to the point of
disappearing, the air intake has been reduced too early in the combustion cycle or the wood
used is too wet. If the wood is dry and the air control is used properly, the flames should
decrease, but remain bright and stable.
On the other hand, too much air can make the fire uncontrollable, creating very high temperatures in
the unit as well as in the chimney and seriously damaging them. A reddish glow on the unit and on the
chimney components indicates overheating. Excessive temperatures can cause a chimney fire.
5.7 Fire Types
Using the air intake control is not the only way to match the appliance heat output to the desired
temperature in the house. A house will need far less heating in October than in January to
maintain a comfortable temperature. Filling the firebox full in fall weather will overheat the space.
Otherwise, the combustion rate will have to be reduced to a minimum and the fire will be smoky
and inefficient.
ENGLISH
Here are some suggestions for building fires suitable for different heating needs.
5.7.1 Flash Fire
To build a small fire that will produce a low heat output, use small pieces of firewood and load
them crisscross in the firebox. The pieces should only be 3" (80 mm) to 4" (100 mm) in diameter.
After raking the coals, lay two pieces parallel to each other diagonally in the firebox and lay two
more across them in the other direction. Open the air control fully and only reduce the air after
the wood is fully flaming.
This kind of fire is good for mild weather and should provide enough heat for up to four hours.
Small fires like this are a good time to use softer wood species and avoid overheating the house.
5.7.2 Long Lasting Fire
For a fire that will last up to eight hours but will not produce intense heat, use soft wood and
place the logs compactly in the firebox. Before reducing the air intake, the load will have to burn
at full heat for long enough for charring the surface of the logs. The flame must be bright before
letting the fire burn by itself.
5.7.3 High Output Fires
When heating needs are high during cold weather, the fire should burn steadily and brightly. This
is the time to use larger pieces of hardwood. Place the biggest pieces at the back of the firebox
and place the rest of the pieces compactly. A densely built fire like this will produce the longest
combustion this stove is capable of.
Special attention must be paid when building fires like this since if the air intake is reduced too
quickly, the fire could smoulder. The wood must be flaming brightly before leaving the fire to
burn.
5.7.4 Burn Cycle Time
The burn cycle time is the period between loading wood on a coal bed and the consumption of
that wood back to a coal bed of the same size. The flaming phase of the fire lasts for roughly
the first half of the burn cycle and the second half is the coal bed phase during which there is
little or no flame.
Page 22
Installation and Operation Manual - Gateway 3500
Page 23
The burning time expected from this stove, including both phases, will vary depending on a
number of things, such as:
− firebox size,
− the amount of wood loaded,
− the species of wood,
− the wood moisture content,
The table below gives an approximate maximum burn cycle time, based on firebox volume.
Table 1 : Approximate Maximum Burn Cycle Time
− the size of the space to be heated,
− the climate zone where the house is, and
− the time of the year.
FIREBOX VOLUME MAXIMUM BURN CYCLE TIME
<1.5 cubic feet 3 to 5 hours
1.5 c.f. to 2.0 c.f 5 to 6 hours
2.0 c.f. to 2.5 c.f. 6 to 8 hours
2.5 c.f. to 3.0 c.f. 8 to 9 hours
>3.0 c.f. 9 to 10 hours
A longer burning time is not necessarily an indication of efficient operation. It is preferable to
build a smaller fire that will provide three or four hours of heating than to fully load the firebox
for a much longer burn. Shorter burn cycles make it easier to match the heat output of the stove
to heat demand for space.
ENGLISH
5.7.5 Logs Orientation
In a relatively square firebox, the wood can be loaded north-south (ends of the logs visible) or
east-west (sides of the logs visible).
North-south loads allow more wood to be loaded at the same time. On the other hand, they
break into smaller pieces faster. This kind of load is good for high output, long lasting fires for
cold weather.
East-west loads allow a limited amount of wood since too many logs could cause them to fall
on the glass. Placed in a compact way, they take a long time before breaking down. They are
excellent for low-intensity, long-lasting fires in relatively mild weather.
5.7.6 Carbon Monoxide
When unburned logs remain in the firebox and the flame disappears, go outside and look at the
chimney exit. If there is visible smoke, it means that there is still combustible to burn but that
the fire lacks air to burn properly. In this situation, the CO rate will increase so it is important to
react. Open the door slightly and move the log with a poker. Turn it over and create a passage
for the air below, making a trench with the coal bed. Add small pieces of wood to restart the
combustion.
Installation and Operation Manual - Gateway 3500
Page 23
Page 24
6. Maintenance
This heater will give many years of reliable service if used and maintained properly. Internal
components of the firebox such as firebricks or refractory panels, baffle and air tubes will wear
over time. Defective parts should always be replaced with original parts.
To avoid premature deterioration, follow the lighting and reloading procedures in section «5.
Burning Wood Efficiently» and also avoid letting the heater run with the air intake fully open for
entire burn cycles.
6.1 Cleaning and Painting
Painted and plated surfaces can be wiped down with a soft, damp cloth. If the paint is scratched
or damaged, it is possible to repaint the heater with a heat-resistant paint. Do not clean or
paint the appliance when it is hot. Before painting, the surface should be sanded lightly with
sandpaper and then wiped off to remove dust. Apply two thin layers of paint.
ENGLISH
6.2 Refractory Materials and Baffle
Periodically inspect the firebricks or the refractory panels and the baffle for damage. Replace
anything that is damaged or broken.
Operation of the heater with a cracked or missing baffle may cause unsafe temperatures
and hazardous conditions and will void the warranty.
6.3 Glass Door
6.3.1 Cleaning
Under normal conditions, the door glass should stay relatively clear. If the firewood is dry
enough and the operating instructions in this manual are followed, a whitish, dusty deposit will
form on the inner surface of the glass after a week or so of use. This is normal and can be easily
removed when the heater is cold by wiping with a damp cloth or paper towel and then drying.
When the stove runs at a low combustion rate, light brown stains may form, especially in the
lower corners of the glass. This indicates that the fire has been smoky and some of the smoke
has condensed on the glass. It also indicates incomplete combustion of the wood, which also
means more smoke emissions and faster formation of creosote in the chimney.
The deposits that form on the glass are the best indication of the fuel quality and success in
properly using the stove. These stains can be cleaned with a special wood stove glass cleaner.
Do not use abrasive products to clean the glass.
The goal should be having a clear glass with no brown stains. If brown stains appear regularly
on the glass, something about the fuel or the operating procedure needs to be changed. When
brown streaks are coming from the edge of the glass, it is time to replace the gasket around the
glass. The glass gasket should be self-adhesive. Always replace the gasket with a genuine one.
Page 24
Do not clean the glass when the stove is hot.
Do not abuse the glass door by striking or slamming shut.
Do not use the stove if the glass is broken.
Installation and Operation Manual - Gateway 3500
Page 25
6.3.2 Replacement
A
The glass used is a ceramic glass, 5/32" (4 mm) thick, 18 ½" x 12 ¼" (468 mm x 310 mm), tested
to reach temperatures up to 1400º F. If the glass breaks, it must be replaced with one having
the same specification.
To remove or replace the glass (D):
1. Remove the door (E) from its hinges and lay it on a
soft, flat surface.
2. Remove the screws (A), the glass retainers (B),
C
D
B
and the metal frames (C).
E
3. Remove the glass (D). If it is damaged install a new
one in place. The replacement glass must have a
gasket all around (see procedure below).
4. Reinstall the glass, being careful to centre the glass
in the door and not to over-tightening the retaining
screw.
The two main causes of broken door glass are uneven placement in the door and overtightening the retaining screws.
6.3.3 Gasket
The glass gasket is flat, adhesive-backed, woven fibreglass. The gasket must be centred on the
edge of the glass.
1. Follow the steps of the previous section to remove the glass. Remove
the old gasket and clean the glass thoroughly.
ENGLISH
2. Peel back a section of the paper covering the adhesive and place the
gasket on a table with the adhesive side up.
3. Stick the end of the gasket to the middle of one edge, then press the
edge of the glass down onto the gasket, taking care that it is perfectly
centred on the gasket.
4. Peel off more of the backing and rotate the glass. The gasket must not
be stretched during installation.
5. Cut the gasket to the required length. Pinch the gasket onto the glass in
a U-shape, all around the glass.
6.4 Door
In order for the stove to burn at its best efficiency, the door must
provide a perfect seal with the firebox. The tightness of the door
seal can be verified by closing and latching the door on a strip
of paper. The test must be performed all around the door. If the
paper slips out easily anywhere, either adjust the door or replace
the gasket.
Installation and Operation Manual - Gateway 3500
Page 25
Page 26
6.4.1 Adjustment
The door seal may be improved with a simple latch mechanism adjustment:
1. Remove the split pin by pulling and turning it using pliers.
2. Turn the handle one counterclockwise turn to increase pressure.
3. Reinstall the split pin with a small hammer.
ENGLISH
Figure 13: Removing the split pin Figure 14: Installing the split pin
6.4.2 Gasket
It is important to replace the gasket with another having the same diameter and density to
maintain a good seal.
1. Remove the door and place it face-down on something
soft like a cushion of rags or a piece of carpet.
2. Remove the old gasket from the door. Use a screwdriver
to scrape the old gasket adhesive from the door gasket
groove.
3. Apply a bead of approximately 3/16" (5 mm) of high
temperature silicone in the door gasket groove. Starting
from the middle, hinges side, press the gasket into
the groove. The gasket must not be stretched during
installation.
4. Leave about ½" (10 mm) long of the gasket when cutting
and press the end into the groove. Tuck any loose fibers
under the gasket and into the silicone.
5. Close the door. Do not use the stove for 24 hours.
6.5 Exhaust System
Wood smoke can condense inside the chimney, forming an inflammable deposit called creosote.
If creosote builds up in the system, it can ignite when a hot fire is burned in the stove. A very
hot fire can progress to the top of the chimney. Severe chimney fires can damage even the best
chimneys. Smouldering, smoky fires can quickly cause a thick layer of creosote to form. When
the stove is operated properly, the exhaust from the chimney is mostly clear and creosote builds
up more slowly.
Page 26
Installation and Operation Manual - Gateway 3500
Page 27
«Creosote - Formation and Need to Removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors condense in the relatively cooler
chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue
lining. When ignited this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected at least once every two months
during the heating season to determine if a creosote buildup has occurred.
If a significant layer of creosote has accumulated (⅛" [3mm] or more) it should be removed
to reduce the risk of a chimney fire.»
6.5.1 Cleaning Frequency
It is not possible to predict how much or how quickly creosote will form in the chimney. It is
important, therefore, to check the build-up in the chimney monthly until the rate of creosote
formation is determined. Even if creosote forms slowly in the system, the chimney should be
cleaned and inspected at least once each year.
Establish a routine for the fuel, wood burner and firing technique. Check daily for creosote
build-up until experience shows how often you need to clean to be safe. Be aware that the
hotter the fire the less creosote is deposited, and weekly cleaning may be necessary in mild
weather even though monthly cleaning may be enough in the coldest months. Contact your local
municipal or provincial fire authority for information on how to handle a chimney fire. Have a
clearly understood plan to handle a chimney fire.
ENGLISH
6.5.2 Sweeping the Chimney
Chimney sweeping can be a difficult and dangerous job.
People with no chimney sweeping experience will often prefer
to hire a professional chimney sweep to inspect and clean the
system for the first time. After seeing the cleaning process,
some will choose to do it themselves.
The chimney should be checked regularly for creosote
build-up. Inspection and cleaning of the chimney can be
facilitated by removing the baffle. See «Appendix 10: Air
Tubes and Baffle Installation» for more details.
6.5.3 Chimney Fire
Regular chimney maintenance and inspection can prevent chimney fires. If you have a chimney
fire, follow these steps:
1. Close the stove door and the air intake control;
2. Alert the occupants of the house of the possible danger;
3. If you require assistance, alert the fire department;
4. If possible, use a dry chemical fire extinguisher, baking soda or sand to control the fire. Do not
use water as it may cause a dangerous steam explosion;
Do not use the appliance again until the stove and its chimney have been inspected by
a qualified chimney sweep or a fire department inspector.

8. Clearances to Combustible Material
The clearances shown in this section have been determined by tests according to procedures
set out in safety standards ULC S627 (Canada), UL 1482 (U.S.A.) and UL 737 (U.S.A.). When
the stove is installed so that its surfaces are at or beyond the minimum clearances specified,
combustible surfaces will not overheat under normal and even abnormal operating conditions.
No part of the stove or flue pipe may be located closer to the combustible than the
minimum clearance figures given.
The clearances to combustible walls may be slightly different in Canada and the U.S.A. and may
also differ depending on whether single or double wall flue pipe is used. The proper clearances
should be used depending on the stove location and the type of flue pipe used.
The clearances of the appliance and the flue pipes must be met individually, meaning the
appliance cannot be installed closer to the combustible materials than the single or double wall
pipe allows. For a safe way to reduce clearances refer to section «8.3 Reducing Clearances

8.2 Floor Protection
This stove is designed to prevent the floor from overheating. However, it must be placed on a
non-flammable surface to protect the floor from hot embers that may fall during loading. The
floor protection must be a continuous, non combustible material, such as steel with a minimum
thickness of 0.015" (0.38 mm) or ceramic tiles sealed together with grout. Cement board, brick,
or any other approved or listed material suited for floor protection. No R factor required.
A material is considered non-combustible when made entirely of steel, iron,
bricks, tiles, concrete, slate, glass or a combination of these materials.
Materials corresponding to ASTM E136 and UL 763 are considered to be
non-combustible materials with the exception of gypsum.
ENGLISH
Any type of tile will require a continuous non combustible sheet beneath to prevent the possibility
of embers falling through to the combustible floor if cracks or separation should occur in the
finished surface. Check local codes for approved alternatives. No protection is required if the
unit is installed on a non-combustible floor (ex: concrete).

8.3 Reducing Clearances Safely
It is often desired to use as little space as possible when
installing a wood stove. To do this, it is possible to reduce the
clearances safely and install the stove closer to the walls by
permanently installing a heat shield between the stove and the
flammable material. The rules for heat shields are sometimes
complicated. Read and apply the instructions carefully. Some
regions may have different regulations. Consult the local
building code or contact the fire department for restrictions,
inspection and installation requirements in the area.
8.3.1 Shield Construction Rules
− Adhesives used in shield construction must not ignite or lose adhesive qualities at temperatures
likely to be encountered.
ENGLISH
− Mounting hardware which extends from the shield surface into combustibles may be used only at
the edges of the shield.
− Mounting hardware must allow full vertical ventilation.
See figures for shield construction to match each letter to a clearance.
A) Minimum clearance between the appliance top and an unshielded combustible ceiling: (41 ⅞")
(1064 mm) .
B) Shield extension above the appliance: 20" (500 mm).
C) Minimum space behind the shield: 1" (25 mm). In Canada ⅞" (21 mm).
D) Clearance along the bottom of the shield: minimum 1" (25 mm) and maximum 3" (75 mm).
E) Minimum clearance along the top of the shield at the ceiling: 3" (75 mm).
F) Mounting hardware must not be located closer than 8" (200 mm) from the vertical centre line of
the appliance.
G) Edge clearance for ceiling shields to side and back walls: 3" (75 mm).
H) Shield extension beyond each side of the appliance: 18" (450 mm).

9. The Venting System
The venting system, made of the chimney and the connecting pipe between the stove and the
chimney, acts as the engine that drives the wood heating system. Even the best stove will not
function safely and efficiently if it is not connected to a suitable chimney.
The heat in the flue gases that pass from the stove and chimney connector into the chimney is
not waste heat. This heat is what the chimney uses to make the draft that draws in combustion
air, keeps smoke inside the stove and safely vents exhaust to outside. The heat in the flue gas
can be seen as the fuel the chimney uses to create draft.
9.1 Suitable Chimneys
This stove will provide optimum efficiency and performance when connected to a 6" (150 mm)
diameter chimney flue system. The connection to a chimney having a diameter of at least
5" (130 mm) (Canada only) or no more than 7" (180 mm) is permitted, if it allows the proper
venting of combustion gases and that such application is verified and authorized by a qualified
installer. Otherwise, the diameter of the flue should be 6" (150 mm).
To be suitable, a factory-built metal chimney must comply with UL 103 HT (U.S.A.) or ULC S629
(Canada).
ENGLISH
9.1.1 Factory-Built Metal Chimney
These are sometimes referred to as ‘high
temp’ chimneys because they have the specific
characteristics to withstand temperatures that can
be created by wood burning stoves.
Factory-built chimneys are tested as a system
with all the necessary components for installation.
The instructions provided with the chimney by
its manufacturer are the only reliable source of
installation guidelines.
To be safe and effective, the chimney must be installed
exactly in accordance with the manufacturer’s
instructions. Only components intended for the
brand and model of chimney should be used. Never
fabricate or substitute parts from other chimney
brands. The chimney must be a type suitable for
solid fuel.
Installation and Operation Manual - Gateway 3500
Page 37
Page 38
9.1.2 Factory-Built Metal Chimney in Mobile Home
For use in a mobile home, this stove is to be
connected to a 6" (150 mm) double wall factory built
chimney pipe conforming to ULC-S629 or UL 103HT
standards for 650°C Factory-built chimney.
The total length of the flue system should be at least
12' (3,6 m)including elbows, from the top of the
stove.
To maintain an effective vapour barrier, insulation
and waterproof at the chimney and outside flue pipe,
a roof flashing must be installed and sealed with
silicone adhesive.
ENGLISH
9.1.3 Masonry Chimney
The stove may also be connected to a masonry
chimney, provided the chimney complies with
the construction rules found in the building code
enforced locally.
The chimney must have either a clay liner or a suitably
listed stainless steel liner. If the masonry chimney
has a square or rectangular liner that is larger in
cross-sectional area than a round 6" (150 mm) flue,
it should be relined with a suitably listed 6" (150 mm)
stainless steel liner.
Do not downsize the flue to less than 6" (150 mm)
unless the venting system is straight and exceeds
25' (7,6 m) in height. When passing through a
combustible wall, the use of an insulated listed
thimble is required.
Page 38
Installation and Operation Manual - Gateway 3500
Page 39
9.2 Minimum Chimney Height
CHIMNEY
MORE THAN 10' (3.1 M)
The top of the chimney should be tall enough to be above the air turbulence caused when wind
blows against the house and its roof. The chimney must extend at least 3 ft. (1 m) above the
highest point of contact with the roof, and at least 2 ft. (60 cm) higher than any roof line or
obstacle within a horizontal distance of 10 ft. (3 m). The total system height, from the floor the
appliance is mounted on to the top of the chimney, should never be less than 15 feet (4.6 m).

9.3 Chimney Location
The location of the chimney is crucial for the proper functioning of the appliance. The chimney
should be installed within the house rather than up an outside wall and should rise straight up
through the tallest part of the house. This installation benefits from being enclosed within the
warm house environment, produce stronger draft, accumulate fewer creosote deposits and will
be unaffected by cold temperatures or harsh winds.
Outside chimneys will lead to cold back drafting when there is no fire in the stove, slow kindling
of new fires, and smoke roll-out when the door is open for loading.
On the other hand, excessive draft will make the fire uncontrollable, creating very high
temperatures in the unit as well as in the chimney and seriously damaging them. A reddish glow
on the unit and on the chimney components indicates overheating. Excessive temperatures can
cause a chimney fire.

9.4 Supply of Combustion Air
9.4.1 Mobile Home
This stove is approved to be installed in a mobile home. It must therefore have a supply of
combustion air from outdoors. The air intake must not draw air from the attic, from the basement,
from a garage or any enclosed space. Air must be drawn from a ventilated crawl space under
the floor or directly from outside.
Install a flexible or rigid, insulated pipe (HVAC type, must comply to ULC S110 and/or UL
181, Class 0 or Class 1) to the fresh air intake. The outside termination must have a weather
protection cap with a wire mesh. Where a mobile home has been converted to a standard house
by mounting it on a permanent basement foundation, the supply of outdoor air is not mandatory.
9.4.2 Conventional House
The safest and most reliable supply of combustion air for a wood stove is from the room in
ENGLISH
which it is installed. Room air is already preheated so it will not chill the fire, and its availability
is not affected by wind pressures on the house. Almost all houses have enough natural leakage
to provide the small amount of air needed by the stove. The only case in which the wood stove
may not have adequate access to combustion air is if the operation of a powerful exhaust device
(such as a kitchen range exhaust) causes the pressure in the house to become negative relative
to outdoors.
Figure 20: Air supply in conventional houses
If an air intake is installed through the wall of the house, its pressure can vary during windy
weather. If smoke puffs from the stove, the air duct should be disconnected to determine if it is
the cause of the problem. In some windy conditions, negative pressure near hood may draw hot
exhaust gases from the stove to outdoors. Check the outdoor air duct for soot deposits when
the full system is cleaned and inspected at least once each year.
Page 40
Installation and Operation Manual - Gateway 3500
Page 41
9.5 Chimney Connector
The chimney connector is the single or double wall pipe installed between the stove flue collar
and the chimney breech.
Double wall chimney connectors are tested and certified. The rules concerning installation are
found in the manufacturer’s installation instructions.
Single wall pipe components are available from most hardware and building supply stores.
These components are usually not tested to a particular standard and certified as compliant.
Therefore, a list of rules found in solid fuel installation codes apply to the installation of single
wall pipe.
9.5.1 Installation configuration
The best installation configuration is the one that rises straight up from the stove to the base of
the chimney with no elbows. Straight assemblies are less likely to cause problems like smoke
roll-out when the door is opened for loading. They are also more stable and easier to maintain
than assemblies with elbows. Horizontal runs of flue pipe should be avoided where possible
because they reduce chimney draft.
ENGLISH
Figure 21: Best Figure 22: Acceptable Figure 23: Avoid
9.5.2 Installation Rules
Failure to install the chimney connector properly can result in house fires. The rules below are
based on those found in the CSA B365 installation code. Carefully follow these installation
instruction rules, or those enforced by the local code.
• Maximum overall length of horizontal pipe: 10’ (3 m) including elbows.
• Minimum clearance from combustible material: 18" (450 mm). The minimum clearance may be
reduced by 50%, to 9" (225 mm) if proper heat shield is installed either on the pipe or on the
combustible surface.
Installation and Operation Manual - Gateway 3500
Page 41
Page 42
• The assembly should be as short and direct as possible between the stove and chimney. The use
of two 45 elbows is preferable to a single 90 elbow.
• The minimum overall height of the chimney system, measured from the stove top to the exterior
termination cap of the chimney should be at least 12’ (3.66 m). A chimney which is too short may
lack the “tunnel effect” required to obtain a proper draft.
• Maximum number of 90 elbows: 2.
• Maximum unsupported horizontal length: 3’ (1 m).
• Galvanized flue pipes must not be used because the coatings vaporize at high temperatures and
release dangerous gases. Use black painted flue pipes.
• Flue pipes must be at least 24 gauge in thickness.
• Flue pipe joints should overlap at least 1 ¼" (30 mm).
• Each joint in the assembly must be fastened with at least three screws.
ENGLISH
• The installation must allow expansion: elbows in assemblies allow for expansion; straight assemblies
should include an inspection wrap with one end unfastened, or a telescopic section.
• Minimum upward slope towards the chimney: ¼ in/ft. (20 mm/m).
• One end of the assembly must be securely fastened to the flue collar with 3 sheet metal screws and
the other end securely fastened to the chimney.
• There must be provision for cleaning of the pipes, either through a clean out or by removal of the
pipe assembly. Removal of the assembly should not require that the stove be moved.
• The male ends of the sections must be oriented towards the appliance so that ashes and
condensation stay inside the pipe.
• A flue pipe must never pass through a combustible floor or ceiling or through an attic, roof space,
closet or concealed space. Where passage through a wall or partition of combustible construction
is desired, the installation shall conform to CAN/CSA-B365, Installation Code for Solid-Fuel-Burning
Appliances and Equipment.
• The chimney connector must be clean and in good condition.

EMPIRE LIMITED LIFETIME WARRANTY
EMPIRE LIMITED LIFETIME WARRANTY
The warranty of the manufacturer extends only to the original retail purchaser and is not transferable. This warranty
covers brand new products only, which have not been altered, modified nor repaired since shipment from factory.
Proof of purchase (dated bill of sale), model name and serial number must be supplied when making any warranty
claim to the EMPIRE dealer.
This warranty applies to normal residential use only. This warranty is void if the unit is used to burn material other
than cordwood (for which the unit is not certified by EPA) and void if not operated according to the owner's manual.
Damages caused by misuse, abuse, improper installation, lack of maintenance, over firing, negligence or accident
during transportation, power failures, downdrafts, venting problems or under-estimated heating area are not covered
by this warranty. The recommended heated area for a given appliance is defined by the manufacturer as its capacity
to maintain a minimum acceptable temperature in the designated area in case of a power failure.
This warranty does not cover any scratch, corrosion, distortion, or discoloration. Any defect or damage caused
by the use of unauthorized or other than original parts voids this warranty. An authorized qualified technician must

the product back to the purchaser will be paid by the manufacturer. Repair work covered by the warranty, executed
at the purchaser’s domicile by an authorized qualified technician requires the prior approval of the manufacturer. All
parts and labour costs covered by this warranty are limited according to the table below.
The manufacturer, at its discretion, may decide to repair or replace any part or unit after inspection and investigation
of the defect. The manufacturer may, at its discretion, fully discharge all obligations with respect to this warranty
by refunding the wholesale price of any warranted but defective parts. The manufacturer shall, in no event, be
responsible for any uncommon, indirect, consequential damages of any nature, which are in excess of the original
