General Safety Information (Continued)
DANGER 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 will require increased maintenance of unit.
CAUTION 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.
- Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble flu-like symptoms such as headaches, dizziness, and/or nausea. If you have these symptoms, your heater may not be working properly.
- Get fresh air at once! Have the heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant

women, those with heart or lung problems, anemia, or those under the influence of alcohol, or at high altitudes.

- Never use this heater in living or sleeping areas.

CAUTION Risk of Burns/Fire/

NOTE: Kerosene should only be stored in a blue container that is clearly marked "kerosene". Never store kerosene in a red container. Red containers are associated 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).
- Use 1-K kerosene in this heater. #1 and #2 fuel oils are a suitable substitute.

- 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. Kerosene deteriorates over time. OLD KEROSENE WILL NOT BURN PROPERLY IN THIS HEATER.
OVERVIEW OF HEATER DESIGN
Fuel System: This heater is equipped with a fuel pump (Gear) that pulls fuel through the fuel line connected to the fuel tank and then pushes fuel through a filter and a solenoid valve and out the burner head nozzle.
This fuel is sprayed into the combustion chamber in a fine mist.

For Technical Support or Troubleshooting, Call: 1-800-323-0620 4

Dayton Operating Instructions and Parts Manual
Model 4XA50C

Assembly (Continued)
"SureFire Ignition": The electronic ignitor sends voltage to a specially designed spark plug.
The spark plug ignites the fuel and air mixture.
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
A. Temperature Limit Control: This heater is equipped with a Temperature Limit Control designed to turn off the heater should the internal temperature rise to an unsafe level. If this device activates and turns your heater off, it may require service.
B. Electrical System Protection: This

Internal Shut-Off Temperature +/-10 degrees
160°F (71°C)

Reset Temperature +/-10 degrees
120°F (49°C)

heater's electrical system is protected by a circuit breaker mounted to the power switch that protects PCB assembly and other electrical components from damage.
C. 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 leveled.

Important notice 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 the heater to burn off outside.

If heater does not start, the thermostat setting may be too low, turn "THERMOSTAT CONTROL KNOB" to higher position to start heater. If heater still does not start, turn power switch to "OFF" and then to "ON" position (See Figure 7). If heater still does not start, see Troubleshooting Chart on page 15.
NOTE: Room Temp. display indicates as following: - When room temp. is less than 0°F: "Lo". - When room temp. is between 0°F and
99°F: Indicates room temperatures. - When room temp. is more than 99°F: "HI".
NOTE: The major electrical components of this heater are protected by a circuit breaker mounted to the power switch. If your heater fails to start, check this first and replace as necessary. You should also check your power source to insure that proper voltage and frequency are being supplied to the heater.
TO STOP HEATER
CAUTION Never unplug
heater while heater is running.
Heater must go through cooling cycle. The cooling cycle cools the combustion chamber. Damage to heater can occur if combustion chamber is not cooled. Do not restart heater until cooling cycle is complete.
1. Turn "THERMOSTAT CONTROL KNOB" to lowest temperature

setting. This will cause heater flame to go out. The motor will continue to run during the cooling cycle. This allows the fan to cool the combustion chamber. When the cooling cycle (approx. 1 min.) is finished, the motor will stop. Do not turn switch to "OFF" or unplug heater until cooling cycle is finished.
2. Turn switch to "OFF" and unplug power cord.
3. To temporarily stop heater, set thermostat at a temperature lower than air around heater. Heater will cycle back on if air temperature around heater matches thermostat setting.
TO RESTART HEATER
CAUTION DO NOT restart
heater until cooling cycle is finished.
The cooling cycle cools the combustion chamber.
1. Wait until cooling cycle is finished after stopping heater.
2. Repeat steps under TO START HEATER.
LONG-TERM STORAGE OF HEATER
1. Remove drain plug from rear bottom side of fuel tank by pulling plug grip downward and drain. See Figure 8.
2. Using a small amount of kerosene, swirl and rinse the inside of the tank.
IMPORTANT: NEVER mix water with kerosene, as it will cause rust inside the tank. Pour the kerosene out, making sure that you remove it all.
IMPORTANT: Do not store kerosene over summer for use during next heating season. Using old fuel may damage heater.
