PRINCIPLE OF AIR CURTAIN INCINERATION
OPERATION
Air curtain incinerators 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 or 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 waste. 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.

OPERATING MANUAL
GENERAL DESCRIPTION S-SERIES
When delivered to a job site, the S-Series machine is ready for use as soon as it is off-
loaded. The entire system is built on a skid type base frame which is designed for easy
movement over the ground. The forward equipment deck supports a four cylinder die-
sel engine, a 60 gallon fuel tank, the direct drive system and the fan. When viewed
from the front of the unit, the patented air disbursement manifold is mounted on the left
top side of the combustion chamber. The back of the firebox is fitted with refractory
lined doors that allow ash removal and access to the (only when it is empty) firebox.
The diesel engine is coupled through a clutch drive PTO (Power Take-Off) that turns
the 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 thermo-ceramic wall, adding oxygen to the combustion zone helping to generate a
hotter more complete fire. This additional agitation helps prevent the fire from starving
for oxygen as the ash builds up during burning operations.
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 reduc-
ing the oxygen and further reducing combustion efficiency. The result is your
through-put drops and smoke increases.
2) Increasing the air flow beyond design standards will over pressurize the firebox
causing larger sized particles to be ejected from the firebox. Besides violating
the EPA limits for PM (particulate matter) the larger, hotter embers ejected will
pose a much greater fire hazard.

SAFETY CONSIDERATIONS
READ ALL SECTIONS OF THIS MANUAL BEFORE YOU BEGIN BURNING OPERATIONS
The S-Series 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 rig-
id safety precautions.
When you are running the S-Series unit, you are responsible for assuring that it is op-
erated in the safest possible manner at all times. If you notice something wrong, cor-
rect it immediately. If you cannot correct it, find someone who can and/or shut down
the machine.
Basic Safety Points:
1) The unit should be placed on cleared, level ground.
The unit should be placed on level ground to facilitate loading, dumping and
moving of the unit. The rear doors weigh approximately 2,000 lbs. each and
should not be opened if the unit is inclined on any axis more than 5 degrees.
2) The unit should be placed such that no combustible material is 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.
increased 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.

Page 6 of 26 (Vers.12.17.2018)
S-100 Refractory Walled Air Curtain Burner with HATZ 3H50TIC Diesel Engine
OPERATING 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 paper and kindling wood. In
the absence of these materials or when starting materials with a high moisture
content use diesel fuel oil as an acceptable option.
5) NEVER climb on the unit to view or light the fire.
Use the ladder built into the unit and never go beyond the top step, or use a
step ladder or similar platform located at a safe distance from the unit. Do not
stand along the rails or on top of the S-Series unit under any circumstance.
6) Shut the unit down in an emergency.
Stop loading the unit, stop the air flow by either disengaging the PTO or by
shutting down the engine. Dump dirt or sand on to the fire. Water should only
be used as a last resort, as it will likely damage the refractory panels.
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.

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 with-
in the 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 per-
cent 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
steel structure can reach temperatures as high as 500ºF. Caution should be tak-
en 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 ash.
DANGER: You must insure debris does not build up on the equipment
front deck. It must be keep clean at all times during operation to prevent a
fire that would damage or destroy the engine and accessories.

OPERATING MANUAL
HOW TO SET UP THE MACHINE
A) POSITIONING THE UNIT
The S-Series units are totally self-contained and ready to use upon delivery to the job
site. The S-Series units are built on a skid base that is designed to facilitate dragging
the unit into position and to move the unit around the site. The weights of the various
units are given in the General Description section. Ensure that lifting or tow cables are
certified for these weights.
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 cur-
tain.
B) PRE-OPERATION CHECKS:
1. Air filter for cleanliness (VERY IMPORTANT)
2. Engine oil level
3. Engine coolant level and antifreeze rating
4. Diesel fuel level
DANGER: When you tow (drag) the S-Series units, especially in soft
soil, watch that the dirt does not build up under the panels and lift the
panels off the rails. Never walk inside the box when it is being towed.
Typically, the softer soils will require a longer cable. If the rear of the
unit sinks in soft soil while it is being towed, use another vehicle to fol-
low and carry some of the load. If you are still having trouble dragging
the unit, try a different length of tow cable. Always stay clear of the tow
cable while the dragging operation is underway.

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, consider access for your truck and trailer to load and unload
the firebox. Ensure there is enough room to maneuver your truck and trailer.
Consider where the waste piles will be located. We generally recommend two waste
piles (explained in next section).
Consider the predominate wind direction. Hot embers will be escaping from the firebox
during all burning operations.
Consider where and how you will empty the firebox. If you are going to ‘drag’ the fire-
box to empty it, ensure there is room and the soil conditions are not too soft. If you are
going to excavate the ash out, then consider where you will dump it. In most cases
cold ash can be reapplied to the land. Check your local ordinances.
Once the box is in position, it is important to place dirt around the inside bottom of the
firebox to close any openings under the skids that may be caused by uneven terrain as
shown on page 4. This will prevent smoke and heat from escaping. Pay particular at-
tention to the seal for the forward (engine side) wall. Any openings under the panels or
forward skid will allow heat from the fire to reach the area below the engine deck. This
could cause the engine deck to become hot enough to burn the paint and be a hazard
to someone standing on the deck.
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.
Never dig a pit in the center of the firebox. This will make it hard to seal the inside of
the box and the walls of the pit can deteriorate during operation allowing smoke and
heat to escape from the firebox or reach the area below the engine deck creating a
hazard for anyone standing on the deck and will void the Air Burners Warranty.

SITE PREPARATION
Faster operation through staging the wood piles
Air Burners Fireboxes were designed primarily as a pollution control device, but oper-
ated 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 possi-
ble. 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 in-
creases) and your
burn rate slows
down, if you over-
load the machine
with materials that
have high moisture
content, such as
tree branches with
leaves and nee-
dles, or green branches such as palm fronds. While these are certainly ok to burn in
the firebox, you want to add them to a hot fire so they dry out and ignite quickly. To
keep the temperature up and to maintain 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.”

Page 13 of 26 (Vers.12.17.2018)
S-100 Refractory Walled Air Curtain Burner with HATZ 3H50TIC Diesel Engine
OPERATING MANUAL
SITE PREPARATION
The “Two Pile System”
For an efficient operation you would have two piles:
The first pile or “main debris” pile, is the material being generated from the land clear-
ing or forest clearing operation and is located away from the ember path but with good
access to your loading machinery.
The second pile or “good wood” pile is your best and most burnable wood. When you
first setup, the site the operator should spend some time sorting through the main de-
bris pile pulling out what appears to be your best, most burnable materials. This is the
material with which you will start the fire and this material will give you a good hot burn-
ing base fire. You will also draw from the “good wood” pile throughout the day if you
should need to stoke up the fire (more on this in the following sections).
As the firebox operator is drawing from the main debris pile throughout the day, he
should continue to replenish the “good wood” pile as necessary. The “good wood” pile
only needs to be enough material to stoke-up the fire if needed and enough material to
get you started the next day.
DANGER: You must insure debris does not build up on the equipment
front deck. It must be kept clean at all times during operation to prevent a
fire that would damage or destroy the engine and accessories.
IMPORTANT WARNING ABOUT BURNING OF PALLETS
Wooden Pallets, especially spent pallets, burn extremely hot. DO NOT load
the FireBox above approximately 3/4 of the height of the burn chamber. Heat
damage to the manifold and other structure may occur which would not be
covered under your Limited Factory Warranty.

S-100 Refractory Walled Air Curtain Burner with HATZ 3H50TIC Diesel Engine
OPERATING MANUAL
LOADING AND STARTING THE FIREBOX
THE GOALS IN STARTING AN S-SERIES UNIT ARE:
To achieve an even fire across the length of the box.
To start the fire from the bottom of the initial pile.
To build a hot base fire.
There are two methods for lighting the unit; a cold start and a hot start. A cold start
means the firebox is clean and has no hot coals left from a previous burn. A hot start
uses heat from the coals of the previous days burn.
COLD START
Unit should be on level ground and the AIR should be off, but the engine can be run-
ning to bring it up to operating temperature.
To prevent smoke from escaping under the box, shovel dirt along the inside bottom
edges of the panels. It will only need a couple inches to prevent the smoke from es-
caping underneath the unit. This is generally only a concern on hard ground and it usu-
ally only lasts for the first hour of burning. As burning continues the ash will build up
and seal off the bottom of the unit as well.
Load your most burnable material (materials from the “good wood” pile as discussed in
the previous section) which is the smaller, dryer and cleaner wood, into the firebox to a
level about half way up. Insure that the entire bottom area of the fire box is covered.
If you are using diesel fuel to assist in the lighting. Spray it (approximately 10 gallons)
across the top of this first load of wood. Be sure to get some diesel on the wood near
the lighting holes in the firebox side and on the wood towards the back. This will help
make it easier to light.
DANGER: If you are using an accelerant, first insure there are NO
HOT COALS remaining in the firebox.
DANGER: DO NOT use highly volatile accelerants such as gasoline or
kerosene, to light the fire. These fluids ignite almost explosively and may
cause injury or death.

Page 15 of 26 (Vers.12.17.2018)
S-100 Refractory Walled Air Curtain Burner with HATZ 3H50TIC Diesel Engine
OPERATING MANUAL
LOADING AND STARTING THE FIREBOX
Once you have this smaller material loaded and your accelerant added (if used), load
some larger, heavier material on top such as logs or big branches. Load these heavier
materials (also from your “good wood” pile) to a height just below the manifold nozzles.
This heavier material will help compress the smaller material which will give you a bet-
ter light-off. If there are large air spaces between the materials in the firebox the heat
will not build up as quickly and the fire may be more difficult to light.
Once burning, this material will become your hot base fire to support continued burn-
ing. Use your best and driest materials (“good wood”) for startup as this will form a
strong base for continued burning plus it will start quicker and burn hotter. If you will be
burning stumps, it is best to load them after the first hour of burning when the fire is up
to full temperature.
The level of material in the fire box for light-off should be kept just below the manifold
nozzles.
If you are using diesel fuel as a igniter, it is sometimes helpful to add a second coat to
the top load again. ENSURE THERE ARE NO HOT COALS REMAINING IN THE
UNIT before adding the accelerant.
Your goal is to develop a good hot base fire and to maintain a good hot fire throughout
your burning operation. This will give you the cleanest burn and the most throughput.
There is always smoke on start-up as all of the material in the box contains moisture,
compared to later in the burn operation when only the new material you are loading
contains moisture. Plus, the air curtain cannot be fully engaged until the fire has
strengthened, or you run the risk of blowing out the fire.
DANGER: NEVER stand on the machine as you may
fall in causing serious injury or death.

LOADING AND STARTING THE FIREBOX
To minimize start-up smoke you can:
Use your driest materials.
Ensure your materials do not retain dirt or sand.
Use diesel fuel to accelerate the light up.
COLD START LIGHTING
1. The air should be off and the engine should be
running, but the PTO should be disengaged.
2. For best results and quickest light up, start the fire
from the bottom because fire will spread upwards
much better than it will spread downwards.
3. Use a propane torch (like a weed burner) or oil
soaked rags on poles to light the fire.
4. The fire can be started from under the rear doors
and from the access door in the forward panel on
the manifold side of the unit.
Access door for lighting
If you are using diesel fuel as a starter, let the fire burn until you begin to see wisps of
white smoke replacing the wisps of black smoke from the diesel fuel or, if you are using
propane torches, wait until the fire has strengthened and flames are reaching the top of
the firebox. Then engage the air at 1,400 RPM. As the fire burns stronger, increase the
air (approximately 200 RPM every 15 minutes) up to maximum.
Don’t increase the air too quickly as you can “blow” the fire out. If you add air and the
smoke gets heavy, then reduce the RPM and let the fire “catch-up.” Once it clears up
you can slowly increase the air again.
Sometimes it is helpful to “fan” the fire during the start-up phase. You accomplish this
by increasing the RPM for 3 to 8 minutes, then decreasing it (i.e. 1,400 RPM up to
2,000 RPM and back down to 1,400 RPM). This sometimes helps to spread the fire
throughout the material. How much air to add and when to add it during startup will
vary with the type of materials being burned.
