OPERATING PRECAUTIONS

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

If natural gas leaks from a connection or fitting, it can mix with the surrounding air, forming a potentially explosive mixture. Obviously, natural gas leaks should be avoided, so set up the natural gas supply with utmost care. Read “Odor Fade” section for additional information about detectingnatural gas leaks. Leak check new connections or reconnections with a soap and water solution and follow all connection instructions herein. Also ask your natural gas dealer for advice on the natural gas 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 producing 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 with parts removed or missing. Likewise, safety systems must not be circumvented or modified in order to operate the heater.

SAFETY PRECAUTIONS

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 natural gas.

4. Protect all natural gas connections from traffic or damage.

5. IMPORTANT Use only the regulator assembly provided with the heater. Match the color stripe on the hangtag attached to the hose assembly with the color on the label located near the natural gas inlet fitting on the heater. Inspect the flexible natural gas connections before each use of the heater. If there is excessive abrasion or wear, or connection is damaged in any way, replace with a connection meets all local, state, etc. codes and requirements

6. For indoor use only. Area must be well ventilated. Figure 1. (also see “Operating Precautions”).

7. If at any time gas odor is detected, IMMEDIATELY DISCONTINUE operation until the source of gas has been located and corrected. Read enclosed Odor fade and Propane Sheet for additional information about detecting propane leaks.

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

9. Maintain minimum clearance from normal combustible material (like paper). Figure 2.

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

11. Operate only on a stable, level surface.

12. Do not use with duct work. Do not restrict inlet or exit.

13. 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).

14. Use only a properly grounded 3-prong receptacle or extension cord.

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

16. Do not adjust the heater combustion tube elevation while heater is running or hot. Adjustments to elevation should only be made after the heater has cooled to touch.

17. 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.

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.

ODOR FADE WARNING

WARNING

Asphyxiation Hazard

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

• Do not use in unventilated areas.

• The flow of combustion and ventilation 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 dataplate, 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. 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 switches. 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 fuel supply valves, or the main fuel supply valve located at the meter if you use natural gas.

• 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 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) and natural gas have 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) or natural gas then do not attempt to light heater, perform service or repairs, or make any adjustments to the heater on the propane (LP) or natural 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 SUPPLIER IMMEDIATELY. DO

NOT WAIT!

HOW MUCH HEAT DO I REQUIRE?

For economy, it is important to match input to that required. But heat requirements often vary. For example, it usually takes a lot more heat to get things warm than it does to keep them that way. Likewise, outside air temperature usually changes during the day so you may need more heat at night than you do in the daytime. An approximation of the heat required can be found by using the chart below.
