WARNING: Operating Precautions
This is a direct fired kerosene convection heater. The intended use is primarily the temporary heating of buildings under construction, conversion or repair. Direct fired means that all combustion products enter the heated space. Although this heater operates at near 100% combustion efficiency, it still produces small amounts of carbon monoxide. Carbon monoxide (called CO) is toxic. CO can accumulate in a heated space and insufficient ventilation can result in death. Symptoms of insufficient ventilation are:

• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat

Be sure to follow the ventilation instructions in the Safety Precautions section. Forced air means that a blower or fan forces air through the heater. Proper combustion depends on this airflow; Therefore, the heater must not be overhauled, modified or operated with removed or missing parts. Likewise, safety systems must not be bypassed or modified in order to operate the heater. If the heater is operated in the presence of other people, it is the user's responsibility to inform those present sufficiently about the safety instructions and the hazards involved.
WARNING: Safety Precautions
THIS IS A HEATER. DO NOT ATTEMPT TO HEAT OR COOK FOOD IN THIS HEATER.

1. Recommended for use with #1-K kerosene fuel. Factory tested for use with #2-K kerosene, #1 or #2 diesel, #1 or #2 heating oil, or JP8 Jet A fuel, and these fuels may also be used. Never use gasoline, biodiesel, drained crankcase oil, naphtha, thinner, alcohol, or other flammable fuels.
2. Check heater carefully for damage. DO NOT operate a damaged heater.
3. DO NOT modify or operate a heater that has been modified from its original condition.
4. Suitable for outdoor and indoor use where adequate ventilation is provided. Never use in areas normally intended for dwellings. Not suitable for use in the weather.
5. When used in a well-ventilated area, allow a minimum of 0.19 m2 (2 sq ft) of opening at floor level and 0.19 m2 (2 sq ft) at ceiling level directly to the exterior. Increase air gaps as marked for each auxiliary heater.
6. Always keep combustible materials, such as paper and wood, at least 250 cm (8 ft) from the heater outlet and 91.4 cm (3 ft) from the top, sides and inlet. Place 3.0 m (10 ft) of canvas or plastic covers and secure to prevent flapping.
7. Attention: Due to high surface and exhaust temperatures, adults and children must keep their distance to avoid burns or inflammation of clothing. Do not touch. Keep children, clothing and flammable objects away.

IMPORTANT:Before filling the fuel tank for the first time or after a long period of storage, drain the fuel
tank from moisture or condensation.

HEATING INITIALIZATION

1. Turn the thermostat to the lowest setting and make sure the "On/Off" switch is in the "Off" position.
2. Plug the heater into a 115V, 60Hz, 1ø, grounded outlet.
3. Turn on the heater by turning the selector switch to the "on" position (the light means the switch is in the "on" position).
4. Set the thermostat to the desired setting. The heating switches on/off as required.

• In cold weather (below 10°F [-12.2°C]) starting can be improved by placing a finger over the pump adjustment screw cover vent hole until the heater starts.
• This device is equipped with an interrupt circuit. The reset is integrated into the "On/Off" switch. If the device does not start, turn the switch to "off", wait 5 minutes and turn the switch to "on".
• EXTENSION CORD REQUIREMENTS: Up to 100 ft (30.5 m) use 16 AWG conductor. 101' - 200' (30.5 - 61.0 m) use 14 AWG conductors.

maintenance and storage

NOTE: To avoid personal injury, unplug the heater from the electrical outlet before servicing. For maximum efficiency and trouble-free operation, perform the following regular maintenance, cleaning, and inspection tasks.
PUMP PRESSURE ADJUSTMENT
Due to differences in fuel viscosity and normal wear and tear on components, the pump pressure on this heater may need to be adjusted.

ADJUSTMENT PROCEDURE

1. Fill the fuel tank.
2. Turn on the heater.
3. Locate the pressure adjustment screw, which is located on the back of the PSU and is accessible through the heated grip.
4. Remove the rubber cap over the fuel pressure adjusting screw.
5. Using a flathead screwdriver, turn the pump pressure adjustment screw:
   • clockwiseto increase pump pressure
   • counterclockwiseReduce pump pressure With the built-in pressure gauge (if available), you can calibrate the pressure quantitatively. See the specification table on page 3 for manufacturer recommended pump pressures.
6. The desired qualitative characteristics of the burner are that the nose cone in the combustion chamber should be cherry red with no dark spots and the flame should not protrude beyond the nose cone.

IMPROPER PRINT SETTING
Problem:
The heater does not have a strong, even flame. Heater smokes and spits out raw fuel.
The nose cone does not turn cherry red.
Setting:
Pump pressure is too low. Turn the adjusting screw clockwise to increase pump pressure.
Problem:
The flame extends beyond the end of the heating element.
Setting:
Pump pressure is too high. Turn the adjusting screw counterclockwise to decrease pump pressure.

Daily Maintenance Schedule

1. GENERALLY. Perform a general visual inspection of the heater for loose or damaged parts. Check nuts and bolts to ensure they are not loosening due to vibration or rough handling. Damaged parts must be repaired or replaced before the heater can be used again. Check the operation of the heater to ensure it is operating normally (see the Maintenance section for a description of normal operation).
   2.FILTER. Dirty air or fuel filters cause an imbalance in the air-fuel mixture. The best indication of this condition is an increase in odors or difficulty lighting the heater. This heater should never be operated without the filters installed. If necessary, clean the filters as described under "500 hours of operation" and "Annually".
   timetables".

500 Hour Maintenance Schedule

1. AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry well and replace. Do not lubricate the filter element. If your heater is used in places with a lot of dust or dirt, clean it as often as necessary (about every 50 hours).
2. REMOVE THE DUST. Clean the heater twice per season (more often in dusty conditions). Blow accumulated dust from the transformer, torch, motor and fan blades with compressed air. Clean the area with a clean, dry cloth. Inspect the area to ensure that all debris has been removed, particularly around the burner and combustion area. Safety goggles must be worn when handling compressed air.
3. CAD CELL. Wipe the glass portion of the Cad cell with a soft, dry cloth.
4. KRUG. The accumulation of fuel dirt and soot from the compressor vanes will eventually fill the passages in the nozzle, resulting in reduced fuel and air flow. The pressure will gradually build up, resulting in an improper air/fuel mixture and excessive odor and smoke. In this case, replace the fuel nozzle.
5. FUEL TANK. Clean twice a season (twice a month if used frequently). Drain and flush the fuel tank with clean fuel oil. Be sure to dispose of used fuel properly.

Annual maintenance plan

1. AIR OUTLET FILTER. Remove the air outlet filter and gently tap the dirty side on a solid object to dislodge debris. Compressed air or liquids must not be used to clean this filter. Place the cleaned filter back into the filter housing in the same position it was in when you removed it. If the filter appears extremely dirty, replace it with a new filter of the same type. When reinstalling the filter cover, make sure the gasket is secure and the filter cover screws are tight to prevent air leaks.
2. FUEL FILTER. Remove the fuel filter from the fuel line and bleed compressed air through the filter in the opposite direction of fuel flow. Safety goggles must be worn when handling compressed air.
3. AIR AND FUEL LINES. If air or fuel lines are removed during cleaning, ensure all connections are secure before operating unit.

Save on computer

Store the heater in a dry, smoke-free and dust-free place. Clean the heater at the end of each heating season as described in the MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends that the tank be completely filled with fuel during long-term storage to minimize condensation in the tank. It is recommended that kerosene is only stored in containers marked "KEROSENE".
