WARNING:Thisproductcontainsand/orgenerateschemicals 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 building materials, paper or cardboard, a safe distance away fromtheheaterasrecommended 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 produces 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 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 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 acquainting those present with the safety precautions and instructions, and of the hazards involved.

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.

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 20 lb. propane/LP tank or larger.

5.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.

6.Always fully assemble heater before each use. Do not use this heater without securing fuel tank as instructed. Minimum clearance from fuel tank to ground is 2".

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

8.Inspect hose assembly before each use of the heater.Ifthereisexcessiveabrasionorwear, or hose is cut, replace with hose assembly listed on parts list before using heater.

9.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.

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

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

12.Maintain minimum clearance to people or normal combustible material (like paper) of 3.6 ft. (1,100 mm) from top and 2 ft. (609 mm) from the reflector.

13.Operate only on a stable, level surface.

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

15.Do not clean heater with combustible or corrosive cleaners. Use warm, soapy water on external surfaces only. Do not submerge in water.

16.Check control compartment burners and circulation 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.

b)Heater does not reach temperature.

c)Uneven burner glow.

d)Burnermakespoppingnoisesduringnormal use, other than during shutdown.

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

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

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

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

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 cleaning 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 regulatorissetforanoutputpressure of 11" W.C. (2.74 kPa).

Propane/LP Safety

WARNING: For outdoor use only.

Asphyxiation Hazard

•Do not use this heater for heating human or animal 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 Specifications, page 2, heater data plate or contact DESA Heating Products 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.
