PRINCIPLE OF AIR CURTAIN INCINERATION
OPERATION
Air curtain burners are designed primarily as a pollution control device. Using a diesel
engine driven fan, these machines generate a curtain of air with a very particular mass
flow and velocity. This curtain of air acts as a trap over the top of an earthen trench or
thermo ceramic lined FireBox. The wood debris is dumped into the trench or FireBox
and then ignited (usually with a propane torch and with a small amount of diesel) just
as you would light any other pile of wood you intended to burn. Once the fire has
gained strength, the air curtain is turned on. The air curtain traps most of the smoke
particles and causes them to re-burn under the air curtain where the temperatures ex-
ceed 1,800º F. These machines do not inject any fuels into the fire, the fire is sustained
only by adding more wood debris. The air from the air curtain is not heated. The only
fuel used in the continuous operation is that of the diesel engine driven fan.

All of this is carefully engineered to provide the correct amount of air at the correct
velocity. It is sometimes thought that more air flow will actually increase the burn
rate. This is INCORRECT. Modifying the air flow will actually have the opposite
effect and reduce the machine’s through-put. Additionally, it will reduce the ma-
chine’s ability to meet air quality minimum standards. There is a maximum rate at
which wood can burn. Trying to exceed that rate by adding more air to an air cur-
tain burner causes two major problems:
1) It will cool the fire reducing combustion efficiency creating more smoke (carbon
dioxide and nitrogen enriched). This will begin a circular effect of further re-
ducing the oxygen and further reducing combustion efficiency. The result is
that your through-put drops and smoke increases.
2) Increasing the air flow beyond design standards will over pressurize the Fire-
Box causing significantly more particles (embers) to be ejected from the Fire-
Box. Besides violating the EPA limits for PM (particulate matter) the larger
hotter embers ejected will pose a much greater fire hazard.
GENERAL DESCRIPTION OF BURNBOSS
The BurnBoss is a proven design that adds mobility to the Air Burners FireBox line of
machines. When delivered to a job site, the machine is ready for use as soon as it is
off-loaded. The FireBox system is built on a patented trailer frame that allows the Fire-
Box to be raised and lowered for easy movement over the ground. The forward equip-
ment deck under the cowling supports a two cylinder diesel engine, a 9 gallon fuel
tank, the direct drive system and the air fan. In addition the battery, FireBox hydraulic
controls are located here. When viewed from the front of the unit, the patented air dis-
bursement manifold is mounted on the left top side of the combustion chamber.
The diesel engine is directly coupled to the main air fan. The high velocity air is sent
down the manifold through the vanes and directed to the outlet nozzles. A balanced
and distributed air flow is directed across the top of the box and then reflected down
into the combustion zone.
The curtain of air acts as a top over the fire box, trapping a large percentage of the es-
caping particulate matter (smoke) and causing it to burn down even further under the
curtain before finally escaping through the curtain as a hot gas. The air from the noz-
zles travels across the FireBox creating the air curtain effect then it reflects off the far
side thermos-ceramic wall adding oxygen to the combustion zone helping to generate
a hotter more complete fire. This additional agitation helps prevent the fire from starv-
ing for oxygen as the ash builds up during burning operations.

SAFETY CONSIDERATIONS
READ ALL SECTIONS OF THIS MANUAL
BEFORE YOU BEGIN BURNING OPERATIONS
The machine operator is dealing with fire on a daily basis; it is very important that each
and every individual involved with the machine be alert and practice very rigid safety
precautions.
When you are running the unit, you are responsible for assuring that it is operated in
the safest possible manner at all times. If you notice something wrong, correct it imme-
diately, and if you cannot correct it, find someone who can and/or shut down the ma-
chine.
Basic Safety Points:
1) The unit must be placed on cleared, level ground.
The unit should be placed on level ground to facilitate loading, dumping and
moving of the unit. The FireBox must touch the ground on all four sides or
smoke and embers will escape.
2) The unit should be placed such that no combustible material is stored
within a minimum 100 foot clearance in any direction.
The S-Series units do not have a bottom and should not be located over com-
bustibles such as dry grass or peat moss. In addition hot embers will escape
from the unit and, depending on the wind, will land on the ground around the
unit. The unit should not be located within 100 feet of any stored combustible
materials. The waste material to be burned during the day’s operation can be
staged within the 100 foot perimeter to facilitate loading. The operator must
monitor the loading pile to insure embers do not ignite the loading pile. The
combustible materials to be stored for burning at a later date must be stored
outside the 100 foot perimeter or in accordance with the chart on page 6 of this
manual which suggests adjustments for wind speed.
3) The unit should not be operated when the wind speeds reach 20 MPH, as
the potential to carry hot embers is significantly increased.
As an operator you should always be aware of wind speed and direction. In-
creased wind speed will affect the integrity of the “air curtain” and will cause hot
embers to travel farther. See the wind speed chart regarding suggested set-
back on page 6.
DANGER:
Watch for the danger notices throughout this manual.

4) NEVER use highly combustible materials to light the unit.
Highly combustible materials such as gasoline, refined spirits, etc. ignite at an
explosive rate which may cause serious injury or death. The safest method to
start the fire in the box is to use materials such as and kindling wood. In the ab-
sence of these materials or when starting materials with a high moisture con-
tent, use diesel fuel oil as an acceptable option.
5) NEVER climb on the unit or lean over to view or light the fire.
Always load and operate the machine from the MANIFOLD side. Hot embers
will escape at a low height opposite the manifold. The left side (opposite the
manifold) of the machine should be restricted access to prevent injury.
6) Shut the unit down in an emergency.
Stop loading the unit, stop the air flow by shutting down the engine. Dump dirt
or sand onto the fire. Water should only be used as a last resort as it will likely
damage the refractory panels.
WIND SPEED VS. SAFE DISTANCE
Approximate Safe Distance for:

16 400' 250' 150'
18 400' 250' 200'
20 500' 250' 200'
DANGER: The above distances serve as a GUIDELINE ONLY! You
MUST ALWAYS observe the down range area regardless of the wind
speed. You must always observe local fire ordinances and directives
from the local fire department or other authorities.
DANGER:
Falling into the fire box will cause serious injury or death.
DO NOT stand within 20 feet of the FireBox on the side opposite the manifold.

7) Personal Safety
Operators need to be aware of the following potential hazards:
A) Flying hot embers being released from the fire. Operators or anyone within
a 100 foot radius of the fire should wear appropriate fire resistant clothing.
The ideal outwear for an operator would include a Nomex jacket, leather gloves,
eye protection, hard hat, cotton work jeans and steel toe boots. Operators
should never wear synthetic material (i.e. polyester) around the fire, as this type
of material can melt and cause injury. Additionally, some synthetic materials will
support combustion and could be very dangerous around fire. One hundred
percent cotton materials would be the minimum, cotton treated with a fire
retardant would be better and fire proof materials, like Nomex would be best.
B) Noise, ear protection is recommended around the machines. It is a
good practice to wear approved ear protection when working in close proximity
to the fan and engine.
C) Hot Panels. The backs of the thermo-ceramic panels and parts of the
orange or green structure can reach temperatures as high as 500 degrees Fahr-
enheit. Caution should be taken to insure operator and visitors do not come in
contact with these hot areas.
D) Ash and dust can be released during the operation and during cleaning.
Operators should wear appropriate breathing masks to protect themselves from
inhaling the dust and fly ash.
DANGER: You must insure combustible debris does not build up on the
equipment. It must be keep clean at all times during operation to prevent a
fire that would damage or destroy the engine and accessories.

HOW TO TRANSPORT THE MACHINE
Towing T24 Model (on-Road use)
Towing the T24 model is like towing any other “heavy” trailer. It is important the frame
rails are as level as possible when hooked to the truck. DO not travel faster than 55
mph (45mph with ember screen attached). The T24 comes equipped with electric
brakes, be sure your truck has a “brake controller” or contact the factory for infor-
mation. The trailer tongue
weight is the same on both units
be sure your hitch assembly is
rated for this towing weight
10200 lbs. (4627kg) and tongue
weight 1200 lbs. (544kg). Al-
ways maintain correct tire pres-
sure to prevent premature wear
and blow outs.
Towing T22 Model (off-Road use only)
The T22 model BurnBoss is unique in that it does not have axles that cross the width
of the machine. This allows for the FireBox to be raised and lowered and to prevent
the fire heat from damaging the wheel and tire assemblies. In addition the T22 has no
suspension as the wheel assemblies are mounted to the frame rails. For this reason
the T22 BurnBoss is designed for Off-Road use. The machine weighs approximately
10200 lbs. (4627kg) and has a towing tongue weight of 1200 lbs. (544kg) Be sure
your truck is rated for these weights. Because there is no suspension on the T22, it is
important that the trailer frame rail is perfectly parallel to the ground when the machine
is connected to the tow vehicle and all the weight is on the tires and on the hitch.
If the front of the frame rail is high then your tongue weight will be significantly higher
as your are actually lifting the first set of tires off the ground. This could cause you to
exceed your trail hitch capacity leading to failure, and it will make it more difficult to
tow.
If the front the frame rail is low then your tongue weight is significantly reduced as the
weight will be on the front set of tires. This will cause premature tire failure and will
make the machine difficult to tow.
DANGER: The BurnBoss lower trailer frame rail MUST be level to the
ground when connected to the tow vehicle or significant accident and injury
may occur.

A) TOWING and TRUCK CONNECTION
1) The BurnBoss lower trailer frame rail MUST be level to the ground when connected.
2) The electrical connection should be made (if applicable to your machine)
3) The front jack stand should be up and secure.
4) The safety chains should be connected to the truck.
5) Install a safety light bar if travelling on public roads (observe applicable local rules
and regulations).
6) Do not exceed 55 mph while towing the Model T24.
7) Do not exceed 25 MPH while towing the Model T22. For long distances always use
a trailer.

HOW TO TRANSPORT THE MACHINE
B) LOWERING THE FIREBOX FOR USE.
1) The FireBox must be on level ground.
2) The machine should be disconnected from the tow vehicle.
3) The front jack stand should be down and secure.
4) Battery switch (if equipped) must be on to operate hydraulic controls.
5) Raise the FireBox to release the load on the safety pins.
6) Remove the safety pins at each end of the FireBox.
7) Lower the FireBox until it contacts the ground.
8) Shovel dirt around the inside edges where the FireBox contacts the ground to pre-
vent heat and smoke from leaking out, especially behind the tires.
Hydraulic Oil
If you are operating in cold weather you may need to warm the hydraulic oil before use. In most cases
running the engine for 30 minutes will generate enough heat. If you still have difficulties operating the
hydraulic system you will need to change the oil to a colder spec oil. Your machine’s hydraulic system
comes standard from the factory with Amsoil Synthetic hydraulic oil ISO32 (Amsoil P/N HVH05-EA). If
your machine will operate in cold temperatures or remain outside for long periods in cold temperatures
you will need to use a synthetic hydraulic oil such as Amsoil P/N HVG05-EA, ISO22. Your machine’s
hydraulic system holds approximately 2.16 gallons (8.19 liters) of fluid.

DANGER: Do not tow the machine without the safety pins in-
stalled as the hydraulic actuators may bleed down dropping the Fire-
Box on the road which may cause injury or death.
DANGER: If the FireBox contains hot ash then it must be moved
immediately after it is raised to prevent damage to the tires.
C) RAISING THE FIREBOX FOR TRANSPORT
1) Connect machine to tow vehicle.
2) Raise jack stand.
3) Raise the FireBox until it stops.
4) Immediately move the machine forward to prevent tire damage by hot embers
5) Install the safety pins.
6) Make all safety chain and truck to machine electrical connections (as applicable).

HOW TO SET UP THE MACHINE
A) POSITIONING THE UNIT
The BurnBoss unit is self-contained and ready to use upon delivery to the job site.
1) The BurnBoss must be setup on level ground.
2) The FireBox is lowered to the ground using the hydraulic controls (see page 12).
3) The bottom edges of the FireBox must touch the ground to insure smoke and em-
bers will not escape underneath the FireBox walls. If necessary shovel some dirt
into (INSIDE) the FireBox to seal the edges. This must be done prior to loading the
FireBox. Add dirt around the bottom behind the tires to prevent any heat from dam-
aging the tires.
4) With respect to the prevailing wind direction, the unit should be positioned such that
the wind comes over the back of the manifold. This is the preferred position. It is
also acceptable to have the wind blow into the manifold. It is discouraged, however,
to have the wind come from either end of the machine, as this will tend to disrupt the
air curtain.
5) The FireBox will be loaded either by hand or by machine
OVER THE MANIFOLD. The FireBox should not be loaded opposite the manifold
as there are many hot embers in this area making it dangerous for personnel.
6) Secure the area (orange safety cones, signs, fencing, etc.) opposite the manifold
(20’ x 20’ see diagram below) and along the side of the machine to insure personnel
do not get near the hot fire or embers.

HOW TO SET UP THE MACHINE
C) STARTING (Kubota Z482)
Turn the speed control knob clockwise to en-
sure engine speed is at idle.
Close battery disconnect switch located on
the battery terminal, if option is installed.
If needed, turn key switch counterclockwise to
the PREHEAT position for a few seconds.
Turn the key switch clockwise to the RUN po-
sition.
The gauges will register to confirm that power
is supplied to the panel.
Start the engine by turning the key switch all
the way clockwise to “START”, then release
key switch, and warm up the engine at idle
speed of 1,000 RPM for 5 to 10 minutes.
Shut the engine down to prepare for loading
and lighting (see pages 16-18 for loading and
lighting instructions). The fan is direct drive,
so leaving the engine running during light-
ing will make it more difficult to light.
Once running, the engine speed may be var-
ied as required by turning the speed control
knob clockwise to decrease, counter clock-
wise to increase.
The maximum engine speed is governed to
provide the correct amount of air flow.

SITE PREPARATION
THE GOALS TO GOOD SITE PREPARATION ARE:
To place the FireBox for easy access.
To sort the waste wood pile.
To organize the inflow of new wood waste.
When locating the FireBox;
1) Consider access for your truck and trailer to load and unload the FireBox. Ensure
there is enough room to maneuver your truck and trailer.
2) Consider where the waste piles will be located. We generally recommend two
waste piles (explained in next section).
3) Consider the predominate wind direction. Hot embers will be escaping from the
FireBox during all burning operations.
4) Consider clearances to empty the FireBox. The unit must raised and towed forward
until all the ash remains behind. When emptying, the tires can not come in contact
with the hot embers or they will be damaged. In most cases cold ash can be reapplied
to the land. Check your local ordinances.
5) Once the box is in position, it is important to place dirt around the inside bottom of
the FireBox where the thermo ceramic panels meet the ground to “seal” the bottom.
This will prevent smoke and heat from escaping. Pay particular attention to the seal
between the tires and firebox and between the front wall and engine bay.
DANGER: This machine DOES NOT prevent hot embers from escaping.
This machine is designed primarily as a pollution control device to reduce
the smoke generated from burning clean wood waste.
DANGER: Never dig a pit in the center of the FireBox. This will allow high level
heat to destroy the bottom of the FireBox, voiding the warranty.

SITE PREPARATION
Faster operation through staging the wood piles
Air Burners FireBoxes were designed primarily as a pollution control device but operat-
ed correctly they will burn clean wood two or three times faster than open burning. To
achieve the best throughput the fire must remain at the highest temperature possible.
You achieve this by remembering three rules;
1) Don’t smother the fire with a huge load or a load of very dense material.
2) Load “less more often” smaller bucket loads more often.
3) Sort out a pile of your best burnable wood, use it to create a hot fire.
The basic principle of operation is not too different from a campfire. You use your best
wood to get it started and if the fire dies down you add some more “Good Wood” to
bring it back up. The big difference is that on your campfire you are probably not add-
ing root balls and leaves and pine needles. These are the high moisture content and
dense materials that bring the fire temperature down.
The temperature drops (smoke increases) and your burn rate slows down, if you over-
load the machine with materials that have
high moisture content such as tree branch-
es with leaves and needles, or green
branches such as palm fronds. While
these are certainly ok to burn in the Fire-
Box, you want to add them to a hot fire, so
they dry out and ignite quickly.
To keep the temperature up and to main-
tain the highest throughput of waste, you
should mix the very burnable wood with the
less burnable materials throughout the
course of the burning operation. The most
common way to accomplish this is to stage
a pile of the most burnable materials or
what we call the “two pile system.”
“If it’s burning clean, it’s burning hot, If there is smoke, you’re losing money.”
