kerosene, No.1 or No.2 Diesel, No.1 or No.2 fuel oil or JP8 Jet A fuel and these fuels may be used as well. Never use gasoline, oil drained from crank cases, naphtha, paint thinners, alcohol or any other highly ammable fuels. Only store kerosene in containers marked Kerosene or Kerosine.

2. Check the heater thoroughly for damage. DO NOT operate a damaged heater.

3. DO NOT modify the heater or operate a heater which has been modied

from its original condition.

4. Suitable for outdoor use. For either outdoor or indoor use where adequate

ventilation is provided. Never use in areas normally for habitation. Not for use where exposed to weather. Operating Precautions This is a kerosene, direct-red, forced air heater. It’s intended use is primarily temporary heating of buildings under construction, alteration or repair. Direct-Fired means that all of the combustion products enter the heated space. Even though this heater operates very close to 100 percent combustion efciency, it still produces small amounts of carbon monoxide. Carbon monoxide (called CO) is toxic. CO can build up in a heated space and failure to provide adequate ventilation could result in death. The symptoms of inadequate ventilation are:

• headache • dizziness

• burning eyes and nose • nausea

• dry mouth or sore throat Be sure to follow advice about ventilation in the Safety Precautions section. Forced Air means that a blower or fan pushes the air through the heater. Proper combustion depends upon this air ow; therefore, the heater must not be revised, modied or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modied in order to operate the heater. When the heater is to be operated in the presence of other people the user is responsible for properly acquainting those present with the safety precautions and instructions, and of the hazards involved. WARNING WARNING CAUTION: Heavy unit, do not attempt to lift without assistance.English

NOTICE: Before lling fuel tank the rst time or after extended storage periods, drain the fuel tank of any moisture or condensation.

4. Locate heater at a safe distance from combustible materials.

PREPARING FOR OPERATION

1. Check the heater for possible shipping damage. If any is found, immediately

contact the manufacturer at 855-805-5745.

2. Follow all WARNINGS and Precautions found in this manual.

3. Fill the fuel tank with clean kerosene. In extremely cold weather, condensation

may develop in the tank and it is recommended that a tablespoon of de-icer be added for each gallon (4 liters) of fuel in the tank. When lling the heater, use at least 2 gallons (8 liters) of fuel. Be sure heater is level and do not overll. Use a funnel or can with a long ll spout.

WARNING:Due to varying fuel viscosities and normal component wear the pump pressure

on this heater may need to be adjusted. The heater should only be operated at the manufacturer’s recommended burner setting. Pressure Adjustment Screw (located at the rear of the heater) ADJUSTMENT PROCEDURE:

3. Locate the fuel pressure adjustment screw. The pressure adjustment screw

is located at the rear of the heater, in the air lter housing cover (slotted adjustment screw).

4. The plug directly under the adjustment screw can be used to install a

pressure gauge. It is not a second adjustment screw.

5. Using a at bladed screw driver, turn the pump pressure adjustment screw

clockwise to increase pump pressure and/or counter-clockwise to decrease pump pressure. Base pump pressures can be found in the specications chart on page 3 of the “Operating Instructions and Owners’ Manual”.

6. For best results, the nose cone in the combustion chamber should be cherry red

with no dark spots and the ame should not extend beyond the nose cone.

IMPROPER PRESSURE ADJUSTMENT

Problem: Heater does not have a strong consistent ame. Heater smokes and spits raw fuel. Nose cone does not get cherry red. English

Daily Maintenance Schedule

1. GENERAL. Make general visual inspection of heater for loose or damaged

parts. Check nuts and bolts to insure against looseness caused by vibration or rough handling. Damaged parts should be repaired or replaced before using heater again. Check heater operation to be sure it is operating normally (See “Servicing” section for description of normal operation).

2. FILTERS. Dirty air or fuel lters will cause an imbalance in the air-fuel mixture.

The best indication that this condition exists is an increase in odors or difculty getting your heater to ignite. This heater should never be operated without the lters in place. If required, clean lters as described under “500 Hours” and “Annual Schedules”. 500 Hour Maintenance Schedule

1. AIR INTAKE FILTER. Remove and wash the lter element with a mild detergent,

dry thoroughly and replace. Do not oil the lter element. If your heater is used where there is considerable dust or dirt, clean as often as necessary (approximately every 50 hrs.).

2. REMOVE DUST. Clean heater twice a season (more often under dusty

conditions). Remove accumulated dust from the transformer, burner, motor and fan blades with compressed air. Wipe area clean with a clean dry cloth. Inspect area to insure all foreign materials are removed, especially around the burner and combustion area. Safety glasses should be worn when using compressed air.

3. CAD CELL. Clean the glass portion of the cad cell with a soft dry cloth.

4. NOZZLE. Accumulation of dirt from fuel and carbon from the compressor vanes

will eventually ll up the passages in the nozzle, resulting in reduction of fuel and air ow. Pressure will gradually increase giving improper fuel-air mixture and excess odor and smoke. If this occurs, replace the fuel nozzle.

5. FUEL TANK. Clean twice a season (during frequently used periods, clean twice

a month). Drain and ush the fuel tank with clean fuel oil. Make sure to dispose of waste fuel properly.

ADJUSTING PUMP PRESSURE

Adjustment: Pump pressure is too low. Turn adjustment screw clockwise to increase pump pressure. Problem: Flame extends beyond the end of the heater. Adjustment: Pump pressure is too high. Turn adjustment screw counter clockwise to decrease pump pressure.English

CAUTION:The parts lists and wiring diagram show the heater as it was con- structed. Do not use a heater which is different from that shown. Heater perfor- mance is effected by air pressure setting. If there is any uncertainty about the air pressure setting, have it checked. A heater which is not working right must be repaired, but only by a trained, experienced service person. Wiring DiagramAnnual Maintenance Schedule

1. AIR OUTPUT FILTER. Remove the air output lter and tap the contaminated

side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this lter. Reinstall cleaned lter in lter body in the same position as it was when removed. If the lter appears extremely dirty, replace it with a new lter of the same type. When replacing the lter cover, be sure the gasket is rmly in place and the screws in the lter cover are tight to prevent air leaks.

2. FUEL FILTER. Remove the fuel lter from fuel line and direct compressed air

through the lter in the opposite direction of fuel ow. Safety glasses should be worn when using compressed air.

3. AIR AND FUEL LINES. If the air or fuel lines are removed during cleaning, be sure

all connections are tight before operating unit. STORAGE Store the heater in a dry location free from fumes or dust. At the end of each heating season, clean the heater as described in the MAINTE- NANCE section. Drain and ush the fuel tank with clean fuel. The manufacturer recommends completely lling the tank with fuel for extended storage to minimize condensation inside the tank. SERVICING A hazardous condition may result if a heater is used that has been modied or is not functioning properly. When the heater is working normally:

• The ame is contained within the heater.

• The ame is essentially yellow.

• There is no strong disagreeable odor, eye burning or other physical discomfort.

• There is no smoke or soot internal or external to the heater.

• There are no unplanned or unexplained shut downs of the heater. WARNING Immediately shut down and do not use a heater that is not working normally. Do not attempt to re-start and use the heater until it has been serviced by qualied service personnel.English
