PRINCIPLE OF AIR CURTAIN INCINERATION
OPERATION
Air curtain incinerators are designed primarily as a pollution control device. Using a
Diesel engine or electric motor 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 fuel) 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 may exceed 1,800º F (950º C). 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.

OPERATING MANUAL
GENERAL DESCRIPTION S-SERIES (E-VERSION)
When delivered to a job site, the S-Series machine is ready for use as soon as it is off-
loaded and properly connected to an appropriate electrical power source. 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 an Electric Motor and a Variable
Frequency Speed Controller (VFD). The motor is directly coupled with 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 re-
fractory lined doors that allow ash removal and access to the burn chamber.
The electric motor that turns the fan is controlled by the VFD unit housed securely be-
hind the front deck enclosure in a NEMA IV housing. The high velocity air is sent down
the manifold through the vanes and directed to the outlet nozzles. A balanced and dis-
tributed 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 FireBox, 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 Fire-
Box causing larger sized particles to be ejected from the FireBox. Besides vio-
lating the EPA limits for PM (particulate matter) the larger hotter embers eject-
ed 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, and 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 mini-
mum 100 foot clearance in any direction.
The S-Series units do not have a bottom and should not be located over combusti-
bles 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.

12 300' 150' 100'
14 300' 200' 150'
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.
4) NEVER use highly combustible materials to light the unit.
Highly combustible materials such as gasoline, refined spirits, etc. ignite at an ex-
plosive 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 die-
sel 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 pushing IN the red POWER BUTTON.
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: Falling into the FireBox will cause serious injury or death.

OPERATING MANUAL
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 motor and accessories.
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 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 ma-
terial can melt and cause injury. Additionally, some synthetic materials will sup-
port 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 electric motor.
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. Oper-
ators should wear appropriate breathing masks to protect themselves from in-
haling the dust and ash.

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 electrically powered S-Series units are built on a skid base that is designed to
facilitate dragging the unit into position near the on-site external electric power connec-
tion and grounding rod. The weights of the various units are given in the General De-
scription section. Ensure 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. Check ground wire connection from grounding lug on FireBox front
deck to earth grounding rod and arrange for repair if needed
2. Check intake air filter of cooling fan on control housing (lower left side)
for cleanliness (open small access door, setup may vary); do not open
the front door of the control panel (See Warning on page i).
3. Make sure Fan Speed Switch is set to OFF Position before turning
main power switch to ON
DANGER: When you tow (drag) the S-Series units, especial-
ly 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 re-
quire a longer cable. If the rear of the unit sinks in soft soil
while it is being towed, use another vehicle to follow 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 wood piles 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 Fire-
Box during all burning operations.
Consider the available 480V three-phase power pole connection and underground
feed to the FireBox from there. Power to be supplied pursuant to Local Code and the
FireBox must also be properly grounded by a grounding rod pursuant to local code.
DANGER: This machine DOES NOT prevent hot embers from es-
caping. This machine is designed primarily as a pollution control de-
vice to reduce the smoke (particulate matter) generated from burning
clean wood waste.

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 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 adding 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 overload the machine
with materials that have high mois-
ture content such as tree branches
with leaves and needles, 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 tem-
perature 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.”

(Vers. 08.20.2022)

Series (E) Refractory Walled Air Curtain Burner (Electric Motor & VFD)
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 landfill or
transfer station operation and is located away from the ember path, but with good ac-
cess 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 and most burnable materials. This is
the material you will start the fire with, this is the material that will give you a good hot
burning 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 keep clean at all times during operation to prevent a
fire that would damage or destroy the motor 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.

LOADING AND STARTING THE FIREBOX
LOADING AN S-SERIES UNIT
You can load the FireBox from either side, but
we recommend loading from the manifold side
because (1) it is safest and (2) it tends to in-
crease the life of the manifold, as it is reduces
the chance for it to be accidentally damaged.
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. To prevent smoke from es-
caping 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 escaping underneath the unit. This is
generally only a concern on hard ground and it usually 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 FireBox 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.

(Vers. 08.20.2022)
Page 14 of 25
Series (E) Refractory Walled Air Curtain Burner (Electric Motor & VFD)
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.
This material once burning 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, then 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 FireBox for light-off should be kept just below the manifold
nozzles.
If you are using Diesel fuel as an 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
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 us-
ing propane torches wait until the fire has strengthened and flames are reaching the
top of the FireBox. Then engage the air setting the speed controller to Position Normal
1. As the fire burns stronger increase the air by switching to Position Normal 2.
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 fan speed and let the fire “catch-up.” Once it clears
up you can increase the air again.
Sometimes it is helpful to “fan” the fire during the start-up phase. You accomplish this
by increasing the air fan RPM’s for 3 to 8 minutes, then decreasing them (i.e. Position
Normal 1 up to Position Normal 2 and back down to Position Normal 1). This some-
times 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.
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. The main power switch should be
ON with the Speed Controller set to OFF and Red
Push Button OFF (pushed in).
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 must be started from the access doors in the
panels on the manifold side of the unit.

OPERATING MANUAL
LOADING AND STARTING THE FIREBOX
HOT START
A hot start uses the coals from the previous day’s burning operation. Depending on
how much ash is in the unit a hot start can be done once or twice before the unit will
need to be emptied. The more ash in the FireBox that you start with the LESS room
you have for burning new materials.
First, insure there are enough coals remaining to generate enough heat to get the new
waste materials burning. You CANNOT add an accelerant, if the waste materials do
not light, as that would be too dangerous. You can use propane torches in the lighting
holes, if you have trouble with a hot start. If the material does not light, the FireBox
must be emptied before trying a cold start with the use of an accelerant.
.
HOT START LIGHTING
Similarly to a cold start you begin with your best and most burnable materials.
1) Load the FireBox to about one third or half way with the “Good Wood”. The wood
should begin burning as soon as you start loading.
2) Set the fan speed at Position Normal 2. This should help fan the flames and spread
the fire. If you experience heavy smoke then reduce the RPM’s by switching to Po-
sition Normal 1 or disengage the air fan altogether by switching to Position OFF. Be
cautious not to “blow out” the fire.
3) As the fire begins to heat up, increase the RPM’s to the maximum Position
Normal 2.
DANGER: Do not use an accelerant for a Hot Start, as it may ignite
unexpectedly and cause injury or death.
