Assembling Handle, Wheel and Cord wrap CAUTION : DO NOT OPERATE heater without support frame assembled to tank. NOTE : Heater should be inspected before each use, and at least annually by a qualitied service person.. KEROSENE (K) For optimal performance of this heater, it is strongly suggested that K kerosene be used. K kerosene has been refined to virtually eliminate contaminants, such as sulpher. Which can cause a rotten egg odor during the operation of the heater. However, # diesel/fuel oil may also be used if K kerosene is not available. Be advised that these fuels do not burn as clean as K kerosene, and care should be taken to provide more fresh air ventilation to accomodate any added contaminants that may be added to the heated space. 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 place outside the living area. NEVER use any fuel other than K kerosene (# diesel and # oil are acceptable substitutes) 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 an explosion or uncontrolled flames. 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.
5. OVERVIEW OF HEATERS DESIGN Fuel System : This heater is equipped with an electric air pump that forces air through the air line connected to the fuel intake and then through a nozzle in the burner head. When the air passes in front of the fuel intake it causes fuel to rise from the tank and into the burner nozzle. This fuel and air mixture 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 : 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. MODELS Internal ShutOff Temp. Reset Temperature Plus/Minus 0 Degrees Plus/Minus 0 Degrees DFA50 / DFA75T 7 F/80 C F/50 C DFA5C/DFA70CV 30 F/0 C 9 F/90 C DFA0CV 9 F/90 C 0 F/0 C Once the temperature falls below the reset temperature you will be able to start your heater. B. Electrical System Protection : This heaters electrical system is protected by a fuse mounted to the PCB assembly that protects it and other electrical components from damage. If your heater fails to operate check this fuse first and replace as needed. FUSE TYPE: All Models 5 volt / 8 amps C. FlameOut Sensor : Utilizes a photocell to monitor the flame in burn chamber during normal operation. It will cause the heater to shutoff should the burner flame extinguish. 7
. 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. WARNING!! : NEVER REFILL HEATER FUEL TANK WHEN HEATER IS OPERATING OR STILL HOT. 7. OPERATION A.) VENTILATION RISK OF INDOOR AIR POLLUTION/USE HEATER ONLY IN WELL VENTILATED AREAS. Provide a fresh air opening of at least three square feet (,800 sq. cm) for each 00,000 BTU/Hr. rating. Provide extra fresh air if more heaters are being used. Example : A DFA0CV heater requires one of the following: a twocar garage door raised six inches (5. cm) a singlecar garage door raised nine inches (.8 cm) two, thirtyinch (7.0 cm) windows raised fifteen inches (38. cm) B.) OPERATION TO START HEATER. Fill fuel tank with kerosene or No. fuel oil.. Attach fuel cap. 3. Plug power cord of heater into threeprong, grounded extension cord. Extension cord must be at least six feet long. Extension Cord Wire Size Requirements to 0 feet (.8 to 3 meters) long, use 8 AWG conductor. to 00 feet (3. to 30.5 meters) long, use AWG conductor. 0 to 00 feet (30.8 to meters) long, use AWG conductor.. Turn THERMOSTAT CONTROL Knob to desired setting (Setting range : 0 F ~ 0 F) (DFA75T/DFA5C/DFA70CV/DFA0CV Models Only) 5. Push BTU control Switch to desired level High or LOW (DFA70CV/DFA0CV Models only, See Figure 8).. Push Power Switch to ON position, Power lndicator Lamp will light and heater will start. NOTE : Room Temperature display explanations are as follows: (DFA5C/DFA70CV/0CV Models only) When the room temperature is less 0, the LED display will show Lo When room temp is between 0 and 99, the number shown on the display is the current room temperature. When room temperature is greater than 99, the LED display will show Hi 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. If heater still does not start, see Troubleshootiong Guide on page5. NOTE : User can Select to operate the heater on two different BTU levels(high or Low). The BTU level can be selected before turning the unit on, or while it is in operation by pushing the BTU control switch. Lamp Lamp Room Temp.

NOTICE : The major electrical components of this heater are protected by a safety fuse mounted to the PCB board. If your heater fails to start, check this fuse 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. Turn switch to OFF and unplug power cord. TO RESTART HEATER.Wait 0 seconds after stopping heater.. Repeat steps under to start heater. EXTRA ELECTRIC OUTLET & PIGGYBACK POWER CORD WARNING : SHOCK HAZARD! Always cover electric outlet when not in use. Don t plug and use a appliance more than 0V/0Hz 5A current in this outlet Cover Outlet Cover Outlet DFA0CV Model Only DFA75T/DFA5C/DFA70CV Models Only Figure 9. Electric Outlet 8. LONG TERM STORAGE OF YOUR HEATER FUEL TANK DRAIN. Drain fuel tank through fuel cap opening. (For DFA50/DFA75T Models Only). Remove fuel drain bolt from rear bottom side of fuel tank using 3/ socket or adjustable wrench and drain. (For DFA5C/DFA70CV/DFA0CV Models Only. See Figure 0) 3. Using a small amount of kerosene, swirl and rinse the inside of the tank. NEVER mix water with the 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 months for use during next heating season. Using old fuel could damage heater.. Reinstall fuel cap. Properly dispose of old and dirty fuel. (For DFA50/DFA75T Models Only) 5. Reinstall Fuel Drain Bolt to Fuel tank and tighten firmly using 3/ socket or adjustable wrench.
