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,asafedistanceaway fromtheheaterasrecommended by the instructions. Never use theheaterinspaceswhichdoor may contain volatile or airborne combustibles,orproductssuch asgasoline,solvents,paintthinner, 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-Firedmeans thatallofthecombustionproductsentertheheated space. Even though this heater operates very close to 100 percent combustion efficiency, it still produces small amounts of carbon monoxide. Some peoplearemoreaffectedbycarbonmonoxidethan others. Early signs of carbon monoxide poisoning resemblethe flu, with headaches, dizziness, and/or nausea. If you have these signs, the heater may not beworkingproperly. Getfreshairatonce!Check for proper ventilation and have heater serviced.
Propane Gas: Propane gas is odorless. An odormaking 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.

SAFETY INFORMATION

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,propaneleaksshouldbeavoided, 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 solutionandfollowallconnectioninstructionsherein. 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.

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, IMMEDIATELY DISCONTINUE operation until the source of gas has been located and corrected. Read Propane/LPSafety,page4 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.
