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 injur y or death.
Under this head-
ing, 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
IMPORT ANT : Every possible circumstance
that might involve a hazard cannot 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.
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 Kero-
sene or No. 1 fuel
oil 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. This heater produces carbon
monoxide, which is listed by the
State of California as a reproductive
toxin under Proposition 65.
• 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 a
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.
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
or No. 1 fuel oil to
avoid risk of fire or explosion. Never
use gasoline, naphtha, paint thinners,
alcohol, or other highly flammable
fuels.
Do not use heavy fuels such as No. 2
fuel oil or No. 2 Diesel. Using heavy
fuels will result in:
• clogged fuel filter and nozzle
• carbon build-up on spark plug
• the need of non-toxic anti-icer in
fuel during very cold weather
IMPORTANT: Use a KEROSENE ONL Y
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. For eign matter may also
require you to clean fuel system often.

Ventilation
Follow the mini-
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
Air
heater.
Inlet
Provide a fresh air opening of at least
mum fresh, outside
three square feet for each 100,000
Btu/Hr rating. Provide extra fresh air if
more heaters are being used.
Example: A 150,000 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-footwide opening) raised 6 inches
• two, 30-inch windows raised 11
inches
