General Safety Information
(Continued)
Never leave the
heater unattended
while burning!
Improper use of this
heater can result in
serious injury or death from burns, fire,
explosion, electrical shock, and/or
carbon monoxide poisoning.
For optimal performance of this heater,
it is strongly suggested that 1-K kerosene
be used. 1-K kerosene has been refined
to virtually eliminate contaminants, such
as sulfur, which can cause a rotten egg
odor during the operation of the heater.
However, #1 or #2 fuel oil (diesel fuel)
may also be used if 1-K kerosene is not
available. Be advised that these fuels do
not burn as clean as 1-K kerosene, and
care should be taken to provide more
fresh air ventilation to accommodate
any added contaminants that may be
added to the heated space. Use of #1
or #2 fuel oil may result in more periodic
maintenance.
Risk of Indoor
Air Pollution!
- Use this heater only in well ventilated
areas! Provide at least a three square
foot (2,800 sq cm) opening of outside
air for every 100,000 BTU/hr of heater
rating.
- People with breathing problems should
consult a physician before using the
heater.

Operation
KEROSENE (1-K)
For optimal performance of this heater,
it is strongly suggested that 1-K kero-
sene be used. 1-K kerosene has been
refined to virtually eliminate contami-
nants, such as sulfur, which can cause a
rotten egg odor during the operation
of the heater. However, #1 or #2 fuel oil
(diesel fuel) may also be used if 1-K
kerosene is not available. Be advised
that these fuels do not burn as clean as
1-K kerosene, and care should be taken
to provide more fresh air ventilation to
accommodate any added contaminants
that may be added to the heated space.
NOTE: Kerosene should only be stored
in a blue container that is clearly
marked “kerosene”. Never store kero-
sene in a red container. Red is associ-
ated with gasoline.
- NEVER store kerosene in the living
space. Kerosene should be stored in a
well ventilated area outside the living
area.
- NEVER use fuel such as gasoline,
benzene, alcohol, white gas, camp
stove fuel, paint thinners, or other oil
compounds in this heater (THESE ARE
VOLATILE FUELS THAT CAN CAUSE A
FIRE OR EXPLOSION).
- NEVER store kerosene in direct
sunlight or near a source of heat.
- NEVER use kerosene that has been
stored from one season to the next.

Operation (Continued)
- Use 1-K kerosene in this heater. #1 fuel
is a suitable substitute.
OVERVIEW OF HEATER DESIGN
Fuel System: This heater is equipped
with an electric magnet pump that
forces fuel through the fuel line
connected to the fuel intake, and then
through a nozzle in the burner head.
This fuel is then sprayed into the
combustion chamber in a fine mist.
Sure Fire Ignition: The electronic
ignitor sends voltage to a specially
designed spark plug. The spark plug
ignites the fuel and air mixture described
above.
The Air System: The heavy duty motor
turns a fan that forces air into and
around the combustion chamber. Here,
the air is heated and then forced out
the front of the heater.
THE SAFETY SYSTEM
Temperature Limit Control: This heater
is equipped with a Temperature Limit
Control designed to turn the heater off
should the internal temperature rise to
an unsafe level. If this device activates
and turns your heater off, it may require
service.
Once the temperature falls below the
reset temperature, you will be able to
start your heater.
Electrical System Protection: This
heater’s electrical system is protected
by a fuse that protects it and other
electrical components from damage. Fuse
is located inside of an in-line “FUSE
BARREL”. If your heater fails to operate,
check this fuse first and replace as needed.
Refer to Specification chart on page 1.
Flame-Out Sensor: Utilizes a photocell
to monitor the flame in burn chamber
during normal operation. It will cause
the heater to shut off should the burner
flame extinguish.
FUELING YOUR HEATER
Never fill the heater fuel tank in the
living space: fill the tank outdoors.
Do not overfill your heater and be sure
heater is level.
Never refill fuel tank
when heater is
operating or still hot.
IMPORTANT: REGARDING FIRST
IGNITION OF HEATER. The first time
you light the heater, it should be done
OUTDOORS. This allows the oils, etc.,
used in manufacturing heater to be
burned off outside.
VENTILATION
Risk of indoor air
pollution. Use heater
only in well ventilated areas.
Provide a fresh air opening of at least
three (3) square feet (2,800 sq. cm) for
each 100,000 BTU/Hr. rating. Provide
extra fresh air if more heaters are
being used.
TO START HEATER
1. Fill fuel tank with kerosene or No. 1
fuel oil.
2. Attach fuel cap.
3. Plug power cord into three-prong,
grounded extension cord. Extension
cord must be at least six feet long.
Extension Cord Wire Size Requirements
• 6 to 100 feet long, use 14 AWG
conductor.
• 101 to 200 feet long, use 12 AWG
conductor.
• 201 to 300 feet long, use 10 AWG
conductor.
• 301 to 400 feet long, use 8 AWG
conductor.
• 401 to 500 feet long, use 6 AWG
conductor.
4. Push the up and down arrow keys on
the control panel to adjust the
thermostat settings and flip the
power switch to "ON".

DAYTON ONE-YEAR LIMITED WARRANTY. Dayton
®
Portable Oil-Fired Heaters, Models covered in this manual, are
warranted by Dayton Electric Mfg. Co. (Dayton) to the original user against defects in workmanship or materials under
normal use for one year after date of purchase. Any part which is determined to be defective in material or workmanship
and returned to an authorized service location, as Dayton designates, shipping costs prepaid, will be, as the exclusive remedy,
repaired or replaced at Dayton’s option. For limited warranty claim procedures, see PROMPT DISPOSITION below. This limited
warranty gives purchasers specific legal rights which vary from jurisdiction to jurisdiction.
LIMITATION OF LIABILITY. To the extent allowable under applicable law, Dayton’s liability for consequential and incidental
damages is expressly disclaimed. Dayton’s liability in all events is limited to and shall not exceed the purchase price paid.
WARRANTY DISCLAIMER. Dayton has made a diligent effort to provide product information and illustrate the products in
this literature accurately; however, such information and illustrations are for the sole purpose of identification, and do not
express or imply a warranty that the products are MERCHANTABLE, or FIT FOR A PARTICULAR PURPOSE, or that the products
will necessarily conform to the illustrations or descriptions. Except as provided below, no warranty or affirmation of fact,
expressed or implied, other than as stated in the “LIMITED WARRANTY” above is made or authorized by Dayton.
PRODUCT SUITABILITY. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use
of products for certain purposes, which may vary from those in neighboring areas. While Dayton attempts to assure that its
products comply with such codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed
or used. Before purchase and use of a product, review the product applications, and all applicable national and local codes
and regulations, and be sure that the product, installation, and use will comply with them.
Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion
or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you; (b) also,
some jurisdictions do not allow a limitation on how long an implied warranty lasts, consequentially the above limitation may
not apply to you; and (c) by law, during the period of this Limited Warranty, any implied warranties of implied merchant-
ability or fitness for a particular purpose applicable to consumer products purchased by consumers, may not be excluded
or otherwise disclaimed.
PROMPT DISPOSITION. Dayton will make a good faith effort for prompt correction or other adjustment with respect to any
product which proves to be defective within limited warranty. For any product believed to be defective within limited
warranty, first write or call dealer from whom the product was purchased. Dealer will give additional directions. If unable to
resolve satisfactorily, write to Dayton at address below, giving dealer’s name, address, date, and number of dealer’s invoice,
and describing the nature of the defect. Title and risk of loss pass to buyer on delivery to common carrier. If product was
damaged in transit to you, file claim with carrier.
