• Fire, burn, inhalation, and explosion hazard. Do not place over compustible materials such as building materials, wood, paper, or cardboard or materials subject to disintegration due toexpansion, such as concrete.

• Use the heater only with propane and the regulator/valve assembly supplied.

• The hose assembly shall be protected fromtraffic, building materials, and contact with hot surfaces both during use and while in storage.

• Check for leaks prior to heater operation. Do this even if this heater was assembled at the store.

• Do not operate the heater if there is a gas leak present.

• Never use a flame to check for gas leaks.

• Inspect the hose for damage before each use. If it is evident there is excessive abrasion or wear,or the hose is cut, it must be replaced prior to the product being put into operation. The replacement hose assembly shall be that specified by the manufacturer.

• Propane gas is not natural gas. Do not try to convert this heater to natural gas as it will void the warranty and is extremely dangerous.

• Place dust cap on cylinder valve outlet wheneverthe cylinder is not in use. Only install the type of dust cap on the cylinder valve outlet that is providedwith the cylinder valve. Other types of caps or plugs may result in leakage of propane.

• Do not store propane cylinders, gasoline, orother flammable liquids in the vicinity of theheater.

• Shut down the heater and allow to cool for five minutes before changing the propane cylinder.

• Do not smoke when attaching or removing the propane cylinder.

• This propane product must be installed in accordance with the latest local codes. In the absence of local codes, use the:
  • United States:
  – National Fuel Gas Code, ANSI Z223.1/NFPA 54
  – Liquified Petroleum (LP) Gas Code, NFPA 58
  • Canada:
  – Natural Gas and Propane Installation Code, CSA B149.1
  – Propane Storage and Handling Code, CSA B149.2.

• Always turn off gas at the propane cylinder (liquid propane also called liquid petroleum gas) when the product is not in use. Disconnect the cylinder before storage.

• Before storing, allow the product to cool for 30 minutes and remove propane cylinder from the unit. Do not store a propane cylinder attached to or near the product. If not followed exactly, a fire causing death or serious injury may occur.

• This heater must be located on stable and level surface and located away from combustible surfaces by no less than 7′ from the front, 4′ from the sides, and 6′ from the top of the heater.

• Keep heater 10′ from propane gas containers. Do not aim heater at propane gas containers within 20′.

• Keep heater 10′ from canvas, tarps, or similar coverings. Secure coverings to prevent flapping or movement that could impact the heater.

• The heater has been shipped from the factory set up for operation on propane gas.

FUEL GAS ODOR – FUEL LEAKS

• WARNING LP gas and natural gas have manmade odorants added specifically for detection 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 TAKE IMMEDIATE ACTION!
• Do not take any action that could ignite the fuel gas. Do not operate any electrical switches. Do not disconnect 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. Properly trained service people must repair any leaks, check for further leakages, and then relight the appliancefor 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.
• WARNING ATTENTION – Critical Points toRemember!
• 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 property trained in the serviceand repair of the heater, ALWAYS be consciouslyaware of the odors of propane (LP) gas andnatural 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, CONTACTYOUR FUEL GAS SUPPLIER IMMEDIATELY. DO NOT WAIT!

PROPANE CYLINDERS

• Never fill the propane cylinder beyond 80 percent full. An overfilled or improperly stored cylinderis a hazard due to possible gas release from the safety release valve. If not followed exactly, a fire causing death or serious injury may occur.
• Only use a propane cylinder that includes a collar to protect the cylinder valve.
• If a leak is detected at any time, get away from the propane cylinder and call the fire department.
• Do not use the product until leak-tested.
• Propane cylinders must be stored outdoors out of reach of children and must not be stored in a building, garage, or any other closed in area.
• Propane cylinder must be located outdoors during operation except during construction or renovation of buildings not occupied by the public.
• Do not operate in altitudes above 2000′.
• Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome. Do not use this tool if you do not understand these operating instructions or you feel the work is  beyondyour capability; contact Milwaukee Tool or a trained professional for additional information or training.

SYMBOLOGY

GROUNDING

WARNING
Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Double Insulated Tools (Two-Prong Plugs)
Tools marked “Double Insulated” do not requiregrounding. They have a special double insulationsystem which satisfies OSHA requirements andcomplies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures B and C.

EXTENSION CORDS
Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

• If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
• Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

**Recommended Minimum Wire Gauge For Extension Cords***

• Based on limiting the line voltage drop to five volts at 150% of the rated amperes.
  READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.

MAINTENANCE

WARNING
To reduce the risk of injury, always unplug the charger and remove the battery pack from the charger or tool before performing any maintenance. Never disassemble the tool, battery pack or charger. Contact a MILWAUKEE service facility for ALL repairs.

Maintaining Tool
The heater should be inspected before each use, and at least annually by a qualified service person. Inspect hose for damage. Never attempt to use damaged or plugged equipment. See your local propane (LP) dealer for repairs.
Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program. Inspect your tool for issues such as undue noise, misalignment or binding of moving parts, breakage of parts, or any other condition that may affect the tool operation.

WARNING
To reduce the risk of personal injury and damage, never immerse your tool, battery pack or charger in liquid or allow a liquid to flow inside them.

Cleaning
Clean dust and debris from any vents. Keep tool clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean, since certain cleaning agents and solvents are harmful to plastics and other insulated parts.

Never use flammable or combustible solvents around tools.
