OPERATING PRECAUTIONS

WARNING

This is a propane, direct-fired, forced air heater. It’s intended use is primarily temporary heating of buildings under construction, alteration or repair.

Propane is heavier than air. If propane leaks from a connection or fitting, it sinks to the floor, collecting there with the surrounding air, forming a potentially explosive mixture. Read enclosed Odor Fade and Propane Sheet for additional information about detecting propane leaks. Leak check new connections or reconnection’s with a soap and water solution.

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. 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 these operating instructions.

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.

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

2.

DO NOT modify the heater or operate a heater which has been modified from its original condition.

3.

Use only propane gas.

4.

Use only WITHDRAWAL propane supply. If there is any question about vapor withdrawal, ask your propane dealer.

5.

Mount the propane cylinders vertically (shutoff valve up). Secure them from falling or being knocked over and protect them from damage.

6.

Locate propane containers at least (USA) 7 ft. (2.13m), (Canada) 10 ft.

(3m) from the heater and do not direct exhaust toward containers within

20’ (6m).

7.

IMPORTANT Use only the hose and regulator assembly provided with the heater. Match the color stripe on the hang tag attached to the hose assembly with the color on the label located near the propane inlet fitting on the heater. Inspect hose assembly before each use of the heater. If there is excessive abrasion or wear, or hose is cut, replace with hose assembly listed on parts list before using heater.

8.

For indoor use only. Adequate ventilation must be provided. Provide minimum openings of 1/2 sq. ft. (.046 m²) near the floor and 1/2 sq. ft. (.046

m²) near the ceiling (also see “Operating Precautions”).

9.

If at any time gas odor is detected, IMMEDIATELY DISCONTINUE operation until the source of gas has been located and corrected.

10. Install the heater such that it is not directly exposed to water, spray, rain and/or dripping water.

11. Maintain minimum clearance from normal combustible material (like paper) as follows: floor-0 ft. (0 m); outlet-6 ft. (1.83m); sides-4 ft. (.61m); top-6 ft. (1.83m). Locate 10 ft. (3m) from canvas or plastic tarpaulins or similar coverings and secure them to prevent flapping or movement due to wind action.

12. Due to the high surface and exhaust temperatures, adults and children must observe clearances to avoid burns or clothing ignition.

13. Operate only on a stable, level surface.

14. Do not use with duct work. Do not restrict inlet or outlet.

15. Do not move, handle or service while hot or burning.

16. Use only in accordance with local codes or, in the absence of local codes, with the Standard for the Storage and Handling of Liquefied

Petroleum Gases ANSI/NFPA 58 and CSA B149.1, Natural Gas and

Propane Installation code.

ODOR FADE WARNING

DANGER

Asphyxiation Hazard

• Do not use this heater for heating human living quarters.

• Do not use in unventilated areas.

• The flow of combustion and air must not be obstructed.

• Proper ventilation air must be provided to support the combustion air requirements of the heater being used.

• Refer to the specification section of the heater’s manual, heater data plate, or contact the factory to determine combustion air ventilation requirements of the heater.

• Lack of proper ventilation air will lead to improper combustion.

• Improper combustion can lead to carbon monoxide poisoning leading to serious injury or death. Symptoms of carbon monoxide poisoning can include headaches dizziness and difficulty in breathing.

FUEL GAS ODOR

LP gas and natural gas have man‑made odorant added specifically for detec‑ tion of fuel gas leaks. If a gas leak occurs you should be able to smell the fuel gas. Since Propane (LP) is heavier than air you should smell for the gas odor low to the floor. ANY GAS ODOR IS YOUR SIGNAL TO GO INTO IMMEDIATE

ACTION!

• Do not take any action that could ignite the fuel gas. Do not operate any electrical switches. Do not remove the battery from the appliance. Do not pull any power supply or extension cords. Do not light matches or any other source of flame. Do not use your telephone.

• Get everyone out of the building and away from the area immediately

• Close all propane (LP) gas tank or cylinder fuel supply valves, or the main fuel supply valve located at the meter if you use natural gas

• Propane (LP) gas is heavier than air and may settle in low areas. When you have reason to suspect a propane leak, keep out of all low areas.

• Use your neighbor’s phone and call your fuel gas supplier and your fire department. Do not re-enter the building or area.

• Stay out of the building and away from the area until declared safe by the firefighters and your fuel gas supplier.

• FINALLY, let the fuel gas service person and the firefighters check for escaped gas. Have them air out the building and area before you return.

6

Properly trained service people must repair any leaks, check for further leakages, and then relight the appliance for you.

ODOR FADING‑NO ODOR DETECTED

• Some people cannot smell well. Some people cannot smell the odor of the man-made chemical added to propane (LP) or natural gas. You must determine if you can smell the odorant in these fuel gases.

• Learn to recognize the odor of propane (LP) gas and natural gas.

Local propane (LP) gas dealers will be more than happy to give you a scratch and sniff pamphlet. Use it to become familiar with the fuel gas odor.

• Smoking can decrease your ability to smell. Being around an odor for a period of time can affect your sensitivity to that particular odor.

Odors present in animal confinement buildings can mask fuel gas odor.

• The odorant in propane (LP) gas and natural gas is colorless and the intensity of its odor can fade under some circumstances.

• If there is an underground leak, the movement of gas through the soil can filter the odorant.

• Propane (LP) gas odor may differ in intensity at different levels. Since

Propane (LP) gas is heavier than air, there may be more odor at lower levels.

• Always be sensitive to the slightest gas odor. If you continue to detect any gas odor, no matter how small, treat it as a serious leak. Immediately go into action as discussed previously.

ATTENTION‑CRITICAL POINTS TO REMEMBER

• Propane (LP) gas has a distinctive odor. Learn to recognize these odors.

(Reference Fuel Gas Odor and Odor Fading sections above).

• Even If you are not properly trained in the service and repair of the heater,

ALWAYS be consciously aware of the odors of propane (LP) gas and natural gas.

• If you have not been properly trained in repair and service of propane

(LP) gas then do not attempt to light heater, perform service or repairs, or make any adjustments to the heater on the propane (LP) gas fuel system.

• A periodic sniff test around the heater or at the heater’s joints; i.e. hose, connections, etc., is a good safety practice under any conditions. If you smell even a small amount of gas, CONTACT YOUR FUEL GAS SUP-

PLIER IMMEDIATELY. DO NOT WAIT!

PREPARING FOR OPERATION

The US Department of Transportation Hazardous Material Regulations

(HMR) actually prohibit transporting batteries in commerce or on airplanes (e.g., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short circuits. So when transporting individual battery packs, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li‑Ion)

• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire.

Toxic fumes and materials are created when lithium ion battery packs are burned.

• If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases.

If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.

• Contents of opened battery cells may cause respiratory irritation.

Provide fresh air. If symptoms persist, seek medical attention.

WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

The RBRC® Seal

The RBRC® (Rechargeable Battery Recycling Corporation)

Seal on the nickel cadmium, nickel metal hydride or lithium-ion batteries (or battery packs) indicates that the costs to recycle these batteries (or battery packs) at the end of their useful life have already been paid by DeWALT. In some areas, it is illegal to place spent nickel cadmium, nickel metal hydride or lithium-ion batteries in the trash or municipal solid waste stream and the Call 2 Recycle® program provides an environmentally conscious alternative.

Call 2 Recycle, Inc., in cooperation with DeWALT and other battery users, has established the program in the United States and Canada to facilitate the collection of spent nickel cadmium, nickel metal hydride or lithium-ion batteries.

Help protect our environment and conserve natural resources by returning the spent nickel cadmium, nickel metal hydride or lithium-ion batteries to an authorized DeWALT service center or to your local retailer for recycling. You may also contact your local recycling center for information on where to drop off the spent battery. RBRC® is a registered trademark of Call 2 Recycle, Inc.

Charger

Be sure to read all safety instructions before using your charger. Consult the chart at the end of this manual for compatibility of chargers and battery packs.

Charging a Battery (Fig. 1)

1.

Plug the charger into an FIG. 1 appropriate outlet before inserting battery pack.

2.

Insert the battery pack into the charger, making sure the battery pack is fully seated in the charger. The red

(charging) light will blink continuously indicating that the charging process has started.

12

3.

The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger.

NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before first use.

CHARGE INDICATORS

CHARGING

FULLY CHARGED

HOT/COLD PACK DELAY

Charger Operation

Refer to the indicators below for the charge status of the battery pack.

* The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.

The charger will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light.

NOTE: This could also mean a problem with a charger.

If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.

HOT/COLD PACK DELAY

When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.

A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

LITHIUM‑ION BATTERY PACKS ONLY

Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.

The tool will automatically turn off if the Electronic Protection System engages.

If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.

Important Charging Notes

1.

Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 °F and 75 °F (18° – 24

°C). DO NOT charge the battery pack in an air temperature below +40 °F

(+4.5 °C), or above +104 °F (+40 °C). This is important and will prevent serious damage to the battery pack.

2.

The charger and battery pack may become warm to the touch while charging. This is a normal condition, and does not indicate a problem.

To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.

3.

If the battery pack does not charge properly:

• Check operation of the receptacle by plugging in a lamp or other appliance;

• Check to see if the receptacle is connected to a light switch which turns the power off when you turn out the lights;

• Move the charger and battery pack to a location where the surrounding air temperature is approximately 65 °F – 75 °F (18° – 24 °C);

• If charging problems persist, take the tool, battery pack and charger to your local service center.

4.

The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use it under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse effect on the battery pack.

5.

Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean it.

6.

Do not freeze or immerse the charger in water or any other liquid.

WARNING: Shock hazard. Don’t allow any liquid to get inside the charger.

Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to enter the battery pack. Never attempt to open the bat-

13

tery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return it to a service center for recycling.

Wall Mounting

These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1” (25.4 mm) long, with a screw head diameter of 0.28–0.35” (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32” (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.

Storage Recommendations

1.

The best storage place is one that is cool and dry, away from direct sunlight and excess heat or cold.

2.

For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge.

The battery pack will need to be recharged before use.
