WARNINGS

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: Fire, burn, inhalation, and explosion hazard. Keep solid combustibles, such as building materials, wood, vinyl siding, 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.

WARNING: Improper installation, adjustment, alteration, service or maintenance can cause injury, property damage, or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.

The heater is designed for use as an infrared patio heater in accordance with the applicable requirements CSA 5.90 U.S Infrared Patio Heaters and the requirements of UL's outline of investigation for gas-fired Infrared Patio Heaters operated at high pressures. Other standards govern the use of fuel gases and heating products for specific uses. Your local authority can advise you about these. The primary purpose of outdoor patio heaters is to provide heating of residential and nonresidential spaces. Properly used, the heater provides safe economical heating.

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.

Carbon Monoxide Poisoning: 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! Have heater serviced.

Propane/LP Gas: Propane/LP gas is odorless. An odor-making agent

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

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

• Install and use heater with care. Follow all local ordinances and codes. In the absence of local ordinances and codes, refer to the

Standard for Storage and Handling of Liquefied Petr oleum Gas, ANSI/NFPA 58. This instructs on the safe storage and handling

of propane/LP gases.

• Use only propane/LP gas set up for vapor withdrawal in a 20 lb. cylinder. Cylinder must be constructed and marked in accordance with specifications for propane/LP cylinders of the U.S. Department of Transportation (DOT). The cylinder must be provided with a shutoff valve terminating in a propane/LP supply cylinder valve outlet. The valve must have external threads and marked "Use with Type 1" and a safety relief device having a direct communication with the vapor space of the cylinder. The cylinder used must include a collar to protect the cylinder valve.

• For outdoor use only. Do not use heater indoors or in any unventilated or enclosed areas. This heater uses oxygen. Do not use in unventilated or enclosed areas where carbon monoxide poisoning may occur.

• Do not use heater in basement or below ground level. Propane/LP gas is heavier than air. If a leak occurs, propane/LP gas will sink to the lowest possible level.

• Keep appliance area clear and free from combustible materials, gasoline, paint thinner, and other flammable vapors and liquids. Dust is combustible. Do not use heater in areas with high dust content.

• Minimum heater clearances from combustibles: Back: 18 inches; Top, Front and Sides: 42 inches (see Figure 1, page 3).

• Before each use, check heater for leaks. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

• Keep propane/LP cylinder below 100° F (38°C).

• Use only the hose and factory preset regulator provided with the heater. Do not adjust regulator as gas leaks may occur.

• Do not block intake air openings, see Figure 12, page 6.

• 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.

• 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.

• Clean inside of control box regularly . Remove screws from control box to open. Clean area with hands or wet rag. Reinstall control box.

CAUTION: The gas pressure regulator provided with this appliance must be used. This regulator is set for an output pressure of 48.6" W.C. (1.8 P.S.I.).

• Specifications: Minimum inlet gas pressure: 11" W.C. Maximum inlet gas pressure: 54" W.C. Required manifold pressure: 48.6" W.C.

• Propane/LP gas cylinder is not provided. Use a 20 lb. propane/LP gas cylinder marked propane. The cylinder supply system must be arranged for vapor withdrawal. The cylinder used must include a collar to protect the cylinder valve. The cylinder must be provided with a shutoff valve terminating in a propane/LP gas supply cylinder valve outlet specified, as applicable, for connection no. 510 in the Standard for Compressed Gas Cylinders Valve Outlet and Inlet Connections, ANSI/CGA-V-1, or connection no. 600 in the Compressed Gas Association’s Limited Standard Cylinder Valve Outlet Connection for Propane Small Valve Series or combination propane/LP gas cylinder valve and quick-disconnect assembly complying with 1.16.5-c and a safety relief device having a direct communication with the vapor space of the cylinder.
