Frequently Asked Questions - DXH50K DEWALT

What fuel to use with the DXH50K heater?
Use only kerosene No. 1-K. The heater has been tested with No. 2-K, diesel No. 1/2, fuel oil No. 1/2, JP8, and Jet A, but No. 1-K is recommended. Never use gasoline, naphtha, or thinners.
Can I use the heater indoors?
Yes, provided there is adequate ventilation. Open an area of at least 0.19 m² (2 ft²) near the floor and another near the ceiling. Never use it in an occupied space without ventilation.
What should I do if I smell gas?
Open windows immediately. Do not light any appliance, do not operate any electrical switch, and do not use the telephone. Call your gas supplier or the fire department from outside.
How to start the heater?
Turn the thermostat to maximum, make sure the ON/OFF switch is OFF, plug the cord into a grounded outlet (115 V, 60 Hz), then flip the switch to ON. The heater will start automatically.
What to do if the heater does not start?
Check that the power supply is correct (115 V, appropriate extension cord). If the unit stopped due to safety, set the switch to OFF, wait 5 minutes, and try again. Refer to the troubleshooting guide in the manual.
How to adjust pump pressure?
Locate the pressure adjustment screw at the back of the heater, in the air filter housing. Use a flathead screwdriver: tighten to increase pressure, loosen to decrease. The nominal pressure is 24 kPa (3.5 psig).
What safety distance to observe around the heater?
Maintain a distance of at least 2.4 m (8 ft) from the hot air outlet, 1 m (3 ft) from the sides and top, and 3 m (10 ft) from tarps or plastic covers. On combustible floors, use an insulating material at least 2.54 cm thick extending 1 m around.
How to maintain the heater filters?
Clean the air intake filter with a mild detergent and dry it (do not oil). Clean the fuel filter by blowing compressed air in the reverse direction of flow. Replace filters if very dirty. Perform these operations every 500 hours or more often in dusty environments.
What to do if the flame is abnormal or smoke occurs?
This usually indicates incorrect pump pressure adjustment or a clogged nozzle. Adjust the pressure as described in the manual. If the problem persists, replace the nozzle. Also check that filters are clean.
Can I use gasoline or another fuel?
No. Use only kerosene No. 1-K or the listed fuels (No. 2-K, diesel, fuel oil, JP8, Jet A). Gasoline, naphtha, thinners, or alcohol are extremely flammable and dangerous.

Operating Precautions

WARNING

This is a kerosene, direct-fired, 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 efficiency, 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. Thesymptomsofinadequate 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 flow; therefore, the heater must not be revised, modified or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modified 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.

Safety Precautions

▲WARNING

  1. Certified for use with No.1-K kerosene fuel. Factory tested for use with No.2-K 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.

Pressure Adjustment Screw (located at the rear of the heater)

DEWALT DXH50K - Maintenance and Storage - 1

text_image OUTPUT FILTER WARNING COVER AND REPLACE FILTER ORDER A YEAR. INTAKE FILTER WASH AND RAY ENERGY 500 INCREASE AS NECESSARY

ADJUSTMENT PROCEDURE:

  1. Fill fuel tank.
  2. Start heater.
  3. Locate the fuel pressure. The pressure adjustment screw is located at the rear of the heater, in the air filter 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 adjust screw.
  5. Using a flat 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 specifications chart on page 3 of the "Operating Instructions and Owners' Manual".
  6. For best results, the nose con in the combustion chamber should be cherry red with no dark spots and the flame should not extend beyond the nose cone.

IMPROPER PRESSURE ADJUSTMENT

Problem: Heater does not have a strong consistent flame.

Heater smokes and spits raw fuel.

Nose cone does not get cherry red.

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.

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 filters will cause an imbalance in the air-fuel mixture. The best indication that this condition exists is an increase in odors or difficulty getting your heater to ignite. This heater should never be operated without the filters in place. If required, clean filters as described under "500 Hours" and "Annual Schedules".

500 Hour Maintenance Schedule

  1. AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry thoroughly and replace. Do not oil the filter 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 fill up the passages in the nozzle, resulting in reduction of fuel and air flow. 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 flush the fuel tank with clean fuel oil. Make sure to dispose of waste fuel properly.

Annual Maintenance Schedule

  1. AIR OUTPUT FILTER. Remove the air output filter and tap the contaminated side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this filter. Reinstall cleaned filter in filter body in the same position as it was when removed. If the filter appears extremely dirty, replace it with a new filter of the same type. When replacing the filter cover, be sure the gasket is firmly in place and the screws in the filter cover are tight to prevent air leaks.
  2. FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air through the filter in the opposite direction of fuel flow. 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 MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends completely filling the tank with fuel for extended storage to minimize condensation inside the tank.
