Oil-Fired Heaters
Description
Dayton Models 2E510F, 2E511F, 3E218F, and 3E219F are 40,000 to 155,000 Btu/Hr
heaters. These heaters use only Kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels
for combustion and electricity to run the motor. They are primarily intended for
indoor and outdoor temporary heating of well-ventilated buildings under
construction, alteration, or repair. They may be used in agricultural, industrial,
and commercial environments. Products of combustion are vented into the
area being heated.
Unpacking
1. Remove all packing items supplied
with heater for shipment.
2. Remove all items from carton.
3. Check heater for any shipping
damage. If heater is damaged,
promptly inform dealer where you

General Safety Information
Make certain you read and understand
all warnings. Keep these instructions
for reference. They are your guide to
safe and proper operation of this
heater.
Safety information appears throughout these instructions. Pay close
attention to them. Below are definitions for the safety information listed
throughout this manual.
Under this heading,
installation, operating,
and maintenance procedures or practices
will be found that, if not carefully
followed, WILL result in IMMEDIATE
serious personal injury or death.
Under this heading,
installation, operating, and maintenance procedures or
practices will be found that, if not
carefully followed, COULD result in
severe personal injury or death.
Under this heading,
installation, operating, and maintenance procedures or
practices will be found that, if not carefully
followed, COULD result in minor personal
injury, product or property damage.
IMPORTANT: Not every possible circumstance that might involve a hazard can be
anticipated. The warnings in this manual
and on tags or decals affixed to the unit
are therefore not all-inclusive. If a
procedure, work method, or operating
technique not specifically recommended
by Dayton is used, you must make sure it
is safe for you and others. You should
also ensure that equipment will not be
damaged or made unsafe by the operating or maintenance method you choose.
This product
contains and/or
generates chemicals known to the
State of California to cause cancer or
birth defects, or other reproductive
harm.
Carbon monoxide
poisoning may lead to
death! Some people are more affected
by carbon monoxide than others. Early
signs of carbon monoxide poisoning
resemble the flu, with headaches,
dizziness, and/or nausea. If you have
these signs, the heater may not be
operating properly, or the areas may
not be sufficiently ventilated. Get fresh
air at once! Have heater serviced.
Improper use of this
heater can cause
serious injury or death from burns, fire,
explosion, electrical shock, and carbon
monoxide poisoning.
Make certain you read and understand
all warnings. Keep these instructions
for reference. They are your guide to
safe and proper operation of this
heater.
Use only Kerosene,
#1/#2 diesel/fuel oil,
JET A or JP-8 fuels to avoid risk of
fire or explosion. Never use gasoline,
naphtha, paint thinners, alcohol, or
other highly flammable fuels.
• Fueling
a) Personnel involved with fueling
shall be qualified and thoroughly
familiar with the manufacturer's
instructions and applicable federal,
state, and local regulations regarding the safe fueling of heating units.
b) Only the type of fuel specified on
the heater's data plate shall be used.
c) All flame, including the pilot
light, if any, shall be extinguished
and the heater allowed to cool, prior
to fueling.
d) During fueling, all fuel lines and
fuel-line connections shall be
inspected for leaks. Any leaks shall
be repaired prior to returning the
heater to service.
e) At no time shall more than one
day's supply of heater fuel be stored
inside a building in the vicinity of
the heater. Bulk fuel storage shall be
outside the structure.
f) All fuel storage shall be located a
minimum of 25 feet from heaters,
torches, welding equipment, and
similar sources of ignition (exception: the fuel reservoir integral with
the heater unit).
g) Whenever possible, fuel storage
shall be confined to areas where
floor penetrations do not permit fuel
to drip onto or be ignited by a fire at
lower elevation.
h) Fuel storage shall be in accordance with the federal, state, or
local authority having jurisdiction.
• Never use heater where gasoline,
paint thinner, or other highly
flammable vapors are present.
• Follow all local ordinances and codes
when using heater.
• Use only in well-vented areas. Provide
at least three square feet of fresh,
outside air for each 100,000 Btu/Hr of
rating.
• Use only in places free of flammable
vapors or high dust content.
• Use only with the electrical voltage
and frequency specified on model
plate.
• Use only a three-prong, grounded
extension cord.

General Safety Information
(Continued)
• Heaters used in the vicinity of
tarpaulins, canvas, or similar
enclosure materials shall be located
a safe distance from such materials.
The recommended minimum safe
distance is 10 feet. It is further
recommended that these enclosure
materials be of a fire retardant
nature. These enclosure materials
shall be securely fastened to
prevent them from igniting or from
upsetting the heater due to wind
action.
• Minimum heater clearances from
combustibles:
Outlet: 8 Ft. Sides: 4 Ft.
Top: 4 Ft. Rear: 4 Ft.
• Locate heater on a stable and level
surface while hot or running or a fire
may occur.
• When moving or storing heater, keep
heater in a level position or fuel
spillage may occur.
• Keep children and animals away
from heater.
• Unplug heater when not in use.
• This heater is equipped with thermostat, heater may start anytime.
• Never use heater in living or sleeping areas.
• Never block air inlet (rear) or air
outlet (front) of heater.
• Never move, handle, refuel, or
service a hot, operating, or pluggedin heater.
• Never attach duct work to front or
rear of heater.
• Warning to New York City Residents
For Use Only At Construction Sites in
accordance with applicable NYC codes
under NYCFD certificate of approval
#4803, #4899, #4908, #4909, or #4934.
Theory of Operation
THE FUEL SYSTEM
The air pump forces air through the
air line. The air is then pushed
through the burner head nozzle. This
air causes fuel to lift from the tank. A
fine mist of fuel is sprayed into the
combustion chamber.
THE AIR SYSTEM
The motor turns the fan. The fan
pushes air into and around the
combustion chamber. This air is heated
and provides a stream of clean, hot air.
THE IGNITION SYSTEM
The ignition control assembly provides
power to the ignitor. This ignites the
fuel/air mixture in the combustion
chamber.
THE FLAME-OUT CONTROL SYSTEM
This system causes the heater to shut
down if the flame goes out.

Fuels
Use only Kerosene,
#1/#2 diesel/fuel
oil, JET A or JP-8 fuels to avoid risk of
fire or explosion. Never use gasoline,
naphtha, paint thinners, alcohol, or
other highly flammable fuels.
Use only kerosene, #1/#2 diesel/fuel oil,
JET A or JP-8 fuels. Heavier fuels such
as No. 2 fuel oil or No. 2 diesel fuel may
also be used but will result in:
• clogged fuel filter and nozzle
• the need of nontoxic anti-icer in
fuel during very cold weather
IMPORTANT: Use a KEROSENE ONLY
container. Be sure storage container is
clean. Foreign matter such as rust, dirt, or
water will cause the flame-out control to
shut down heater. Foreign matter may also
require you to clean fuel system often.

2. Place cap nuts on axle ends. Gently
tap with hammer to secure.
3. Place heater on wheel support
frame. Make sure air inlet end (rear)
of heater is over wheels. Line up
holes on fuel tank flange with holes
on wheel support frame.
4. Place handles on top of fuel tank
flange. Insert screws through
handles, fuel tank flange, and wheel
support frame. Attach nut finger tight
after inserting each screw.
5. After inserting all screws, tighten
nuts firmly.
Ventilation
Follow the mini-
mum fresh, outside
air ventilation requirements. If proper
fresh, outside air ventilation is not
provided, carbon monoxide poisoning
can occur. Provide proper fresh,
outside air ventilation before running
heater.
Provide a fresh air opening of at least
three square feet for each 100,000
Btu/Hr rating. Provide extra fresh air if
more heaters are being used.
Example: A 155,000 Btu/Hr heater
requires one of the following:
• a two-car garage door (16-foot-wide
opening) raised 3.5 inches
• a single-car garage door (9-foot-
wide opening) raised 6.5 inches
• two, 30-inch windows raised 11.5
inches

seconds, then heater will start.
8. If equipped, adjust thermostat knob
to the desired setting.
NOTE: If equipped, a cold heater may
affect the thermostat setting. Further
adjustments may be needed until the
heater cycles at the desired setting.
This thermostat is a general-heating
control. It is not intended for precise
temperature control.
