SAFETY INFORMATION

WARNING: This product contains and/or generates chemicals known to the State of California to cause cancer or birth defects, or other reproductive harm.

WARNING: Not for home or recreational vehicle use.

WARNING: Fire, burn, inhalation, and explosion hazard. Keep solid combustibles, such as build ing materials, paper or cardboard, a safe distance away from the heater as recommended by the instructions. Never use the heater in spaces which do or may contain volatile or airborne combustibles, or products such as gasoline, solvents, paint thinner, dust particles or unknown chemicals.

We cannot foresee every use which may be made of our heaters. Check with your local ﬁre safety authority if you have questions about heater use.

Other standards govern the use of fuel gases and heat producing products for speciﬁc uses. Your local authorities can advise you about these.

Carbon Monoxide Poisoning: 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 pro

duces small amounts of carbon monoxide. Some people are more affected by carbon monoxide than others. Early signs of carbon monoxide poisoning resemble the ﬂu, with headaches, dizziness, and/or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Check for proper ventilation and have heater serviced.

Propane Gas: Propane gas is odorless. An odor-

making agent is added to propane gas. The odor helps you detect a propane gas leak. However, the odor added to propane gas can fade. Propane gas may be present even though no odor exists.

This is a propane, direct-ﬁred heater. 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 Propane/LP Safety, page 4 for additional informa tion 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 them to check it if there are any questions.

When the heater is to be operated in the presence of other people the user is responsible for properly ac quainting those present with the safety precautions and instructions, and of the hazards involved.

Make certain you read and understand all warn ings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.

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/LP gas.

4. Use only VAPOR WITHDRAWAL propane supply. The propane cylinder must be arranged for vapor-withdrawal, in accordance with the

Compress Gas Associations, Small Propane Bottle Assembly. If there is any question about

vapor withdrawal, ask your propane dealer.

5. Never use the heater if the ballast weight is not assembled onto the base. The base must be weighted to avoid tipping.

6. Use only the hose and regulator assembly provided with the heater.

7. 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. This heater is for OUTDOOR USE ONLY, even so, make sure that there is ample fresh air ventilation. Do not use in buildings, garages or other enclosed spaces.

9. If at any time gas odor is detected, IMMEDI ATELY DISCONTINUE operation until the source of gas has been located and corrected. Read Propane Safety, page 4 for additional information about detecting propane leaks.

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

11. Maintain minimum clearance to people or normal combustible material (like paper) of

3.6 ft. (1100 mm) from top and 2 ft. (609 mm) from the reﬂector.

12. Operate only on a stable, level surface.

13. Do not spray aerosols near the heater during use or shortly thereafter.

14. Do not clean heater with combustible or cor rosive cleaners. Use warm, soapy water.

15. Check control compartment burners and cir culation air passageways for free air passage, make sure that there are no obstructions. These areas are a common location for spider webs, which can present a dangerous condition, damage the heater and render it unsafe for use. The heater must be checked if any of the following conditions exist:

a) Gas smell along with predominate yellow

tipping of the burner. b) Heater does not reach temperature. c) Uneven burner glow. d) Burner makes popping noises during nor

mal use, other than during shutdown.

114144-01D

16. Use only soapy water (1 part liquid dishwashing detergent to 3 parts water) to conduct leak tests whenever a propane cylinder is connected. Bubbles indicate a leak.

17. Do not adjust gas regulator. If you are unsure of your appliances gas type or pressure, call a qualiﬁed service person.

18. Place the control knob on "OFF" position when heater is not in use.

19. Always disconnect the gas supply after the heater is turned "OFF".

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

21. Allow 45 minutes to cool down after use before attempting to move heater.

22. Do not operate this appliance in windy con ditions. Maximum allowable wind speed is 10 mph (16 Km/h).

23. Do not operate this appliance in temperature conditions below 40° F (5° C).

24. Keep heater away from areas where ﬂammable liquids, vapors or solids are stored or used.

25. If operated in salt air environments, the

unit will require more frequent cleaning;

otherwise, the longevity of the unit will deteriorate rapidly. Use warm soapy water to clean the unit.

26. Items or material, when stored under the heater, will be subjected to radiant heat and could be seriously damaged.

27. Use only in accordance with local codes, or in the absence of local codes, with the National

Fuel Gas Code ANSI Z223.1

Any guard or other protective device removed for servicing must be replaced prior to operating the heater.

Surface temperatures become very hot when operating heater. Children

and adults should stay away to avoid burns or clothing ignition.

Young children should be carefully supervised when they are in the area of the heater.

Clothing or other ﬂammable mate rials should not be hung from the heater, or placed on or near heater.

SAFETY INFORMATION

Continued

Installation and repair should be done by a qualiﬁed service person. The heater should be inspected before use and at least annually by a qualiﬁed service person. More frequent cleanings may be required as necessary. It is imperative that control compartments, burners and circulating air passageways of the heater be kept clean.

CAUTION: The gas pressure regulator provided with this appliance must be used. This regulator is set for an output pressure of 11" W.C. (2.74 kPa).

SERVICING

To assure safety, proper function and longevity of the heater, regular maintenance is required. The frequency of maintenance will depend on the usage of the unit. Review the following concern ing the criteria for a properly functioning heater. Failing to follow proper, regular maintenance will void warranty.

A hazardous condition may result if a heater is used that has been modiﬁed or is not functioning properly. When the heater is working properly:

• The ﬂame is contained within the heater.

• The ﬂame is essentially blue with perhaps some

yellow tipping.

• There is no strong disagreeable odor, eye burn

ing or other physical discomfort.

• There is no smoke or soot internal or external

to the heater.

• There are no unplanned or unexplained shut

downs of the heater.

The parts lists and wiring diagram show the heater as it was constructed. Do not use a heater which is different from that shown. In this regard, use only the hose, regulator and cylinder connection ﬁtting (called a POL ﬁtting) supplied with the heater. IMPORTANT: Do not use alternates. For this heater, the regulator must be set as shown in Speci- ﬁcations, page 2. If there is any uncertainty about the regulator setting, have it checked.
