FUEL SELECTION

1. All models can use 7 different fuels: K1 Kerosene, #1 Fuel Oil, #1, Diesel, #2 Fuel Oil, #2 Diesel, Jet A, JP-8
2. K1 Kerosene is recommended for optimal combustion and performance, and for less maintenance. K1 is also the optimal fuel choice in extremely low temperatures of 15°F or less, as its pour-point/”gel-point” varies depending on the refinery, but it is always far below the lowest temperatures reached North America.
3. Jet A and JP-8 are also excellent choices for clean combustion, reduced maintenance, and temperatures below 15°F, but they are rarely found outside of the aviation industry or the military.

4. 1 Fuel Oil, #1 Diesel, #2 Fuel Oil, #2 Diesel are often selected, as they are readily available. However, the usermust understand that Fuel Oil and Diesel are less refined, and therefore the user should be aware of the following:

5. Diesel and #1 Fuel Oil will have some degree of increased smoke/soot during ignition, increased smell, and increased regular cleaning/maintenance.
6. Diesel and #2 Fuel Oil will, generally depending on the regional refinery, burn dirtier than #1 fuels. The use of #2 fuels will result in a little more smoke/soot during ignition, a greater increase in smell, and will require more regular cleaning/maintenance than #1 fuels.
7. At temperatures lower than 15°F, most diesel/fuel oil blends will become more viscous (start to gel) as the diesel falls below its pour point (starts to “gel”), and may pose a challenge igniting the heater and with continuous operation of the heater. There are troubleshooting steps for this situation, but selecting K1 (or JP-8/Jet A) is recommended when operating below 15°F. The colder the temperatures the more likely you could problems you will experience diesel gelling.
8. Diesel fuel gelling happens when the paraffin usually present in diesel starts to solidify when the temperature drops. At 32° degrees, the wax in liquid form will crystallize and leave the fuel clouded; this can start to have an effect on the fuel filter and the nozzle. If the nozzle is getting coated the spray pattern will not be correct which can cause white smoke and performance problems.

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 1-K kerosene (#1/#2 diesel/fuel oil, JET A or JP-8 fuels 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.

IMPORTANT NOTICE REGARDING FIRST IGNITION OF HEATER: manufacturing the heater to burn off outside.
WARNING : NEVER REFILL HEATER FUEL TANK WHEN HEATER IS OPERATING OR STILL HOT.

OPERATION

• A.) VENTILATIONRISK OF INDOOR AIR POLLUTION/USE HEATER ONLY IN WELL VENTILATED AREAS. Provide a fresh air opening of at least three square feet (2,800 sq. cm) for each 100,000 BTU/Hr. rating. Provide extra fresh air if more heaters are being used.
  Example : A DFA220CV heater requires one of the following:

  • a two-car garage door raised six inches (15.24 cm)
  • a single-car garage door raised nine inches (22.86 cm)

• TO START HEATER

1. 1\. Fill fuel tank with fuel.  

NOTE : Kerosene is recommended when the temperature drops below 0℉(-18℃) to prevent ignition delay or failure.

2. Attach fuel cap.
3. Plug power cord of heater into three-prong, grounded extension cord. Extension cord must be at least six feet long. Extension Cord Wire Size Requirements
  * 6 to 100 feet (1.8 to 30.5 meters) long, use 16 AWG conductor.
  * 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.
4. Turn “THERMOSTAT CONTROL knob” to desired setting (setting range : 40˚F ~ 110˚F)(DFA80T/135C/180CV/220CV Models Only)
5. Push “BTU control Switch” to “High” level. (See Figure 8.) (DFA180CV/220CV Models Only)
6. Push Power Switch to “ON” position, Power lndicator Lamp will light and heater will start.
7. After startup, push “BTU control switch” to desired level “High or Low”.

NOTE : Room Temperature display explanations are as follows: (DFA135C/180CV/220CV 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 page15.

NOTE : User can select to operate the heater on two different BTU levels(High or Low). To stabilize heater and prevent ignition delay, select BTU level after turning the heater on, or while it is in operation by pushing the BTU control switch. If the heater started at low BTU level in cold weather or low fuel tank, ignition failure can occur. block fanguard in half with newspaper etc. until the heater ignites.

NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
