OPERATING PRECAUTIONS

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. Obviously, propane leaks should be avoided, so set up the propane supply with utmost care. Read enclosed Odor Fade and Propane Sheet for additional information about detecting propane leaks. Leak check new connections or reconnections with a soap and water solution and follow all connection instructions herein. Also, ask your propane dealer for advice on the propane application and supply installation and ask him to check it if there are any questions.This heater was designed and certified for use as a construction heater in accordance with ANSI Standard Z83.7/CGA 2.14. Check with your local fire safety authority if you have any questions about your applications. Other standards govern the use of fuel gases and heat producting products in specific applications. Your local authority can advise you about these.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. We can tolerate small amounts but not a lot. 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

So, 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 withparts 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

  1. Check the heater thoroughly for DO NOT operate a damaged heater.
  2. DO NOT modify the heater or operate a heater which has been modified from its original
  3. Use only propane
  4. Use only VAPOR WITHDRAWAL propane 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
  6. Locate propane containers at least (USA) 7 (2.13m), (Canada) 10 ft. (3m) from the heater and do not direct exhaust toward containers.
  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 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. Area must be well ventilated. Provide minimum openings of 1/2 sq. ft. (.046 m ) near the floor and 1/2 ft. (.046 m ) 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 Read enclosed Odor fade and Propane Sheet for additional information about detecting propane leaks.
  10. Install the heater such that is is not directly exposed to water spray, rain and/or dripping

1 . Maintain minimum clearance from normal combustible material (like paper) as follows: floor-0 ft. (0 m); outlet-6 ft. (1.83m); sides-2 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.

  1. Due to the high surface and exhaust temperatures, adults and children must observe clearances to avoid burns or clothing
  2. Operate only on a stable, level
  3. Do not use with duct Do not restrict inlet or exit.
  4. Use only the electrical power specified. The electrical connection and grounding must comply with National Electrical Code – ANSI/NFPA 70 (USA) and CSA C22.1 Canadian Electrical Code, Part 1 (Canada).
  5. Use only a properly grounded 3-prong receptacle or extension cord (6 ft (1.83m) in length minimum).
  6. Do not move, handle or service while hot or
  7. 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 1, Natural Gas and Propane Installation Code.

Symptom of carbon monoxide poisoning can include headaches dizziness and difficulty in breathing.

FUEL GAS ODOR

LP gas and natural gas have man‑made 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 GO INTO IMMEDIATE ACTION!

  • Do not take any action that could ignite the fuel gas. Do not operate any electrical 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
  • 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
  • Propane (LP) gas is heavier than air and may settle in low 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
  • Stay out of the building and away from the area until declared safe by the firefighters and your fuel gas

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 appliance for you.

ODOR FADING ‑ NO ODOR DETECTED

  • Some people cannot smell 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 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 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
  • If there is an underground leak, the movement of gas through the soil can filter the
  • Propane (LP) gas odor may differ in intensity at different 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 Learn to recognize these odors. (Reference Fuel Gas Odor and Odor Fading sections above.
  • Even If you are not property trained in the service and repair of the heater, ALWAYS be consciously aware of the odors of propane (LP) gas and natural
  • 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
  • A periodic sniff test around the heater or at the heater’s joints; 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 SUPPLIER IMMEDIATELY. DO NOT WAIT!
