All gasoline, propane and natural gas catalytic converters, exhaust gas purifiers and purifier mufflers will produce very high exhaust gas temperatures (1300°F+), surface temperatures (1200°F+) and sparks. It is very important to keep this fact in mind during catalytic converter installation, engine operation and following engine shutdown. Please follow all the following safety steps and recommendations:

1) During installation, make sure that all flammable materials and related engine/chassis components are located at least 12 inches from the catalytic converter (where applicable). In addition minimize the presence of any and all flammable materials which will be in the general working area of the equipment incorporating the catalytic converter. Install a class ABC fire extinguisher in the immediate work area.

2) Prior to initial start-up of the engine with the catalytic converter, ensure that the engine is operating correctly in accordance with manufacturers specifications and tolerances. An engine which is worn out, running too rich, misfiring or consuming too much lubrication oil will produce visible flames from the outlet of the catalytic converter. Correct these problems prior to catalytic converter installation.

3) During engine operation ensure that the exhaust gas flow of the catalytic converter does not com in contact with humans, animals or any flammable materials. Following engine shutdown the surface temperatures of the catalytic converter will remain very high for a period of time. Usually surface temperatures will remain at high levels for a minimum period of 20 to 40 minutes after engine shutdown. Avoid contact with any part of the catalytic converter, the converter heat shields or any part of the exhaust system following engine shutdown.

4) During re-fueling of the engine ensure that the engine was been turned off and allowed to safely cool for a minimum period of 20 to 40 minutes in order to prevent the ignition of gasoline liquid vapors. During the addition of lubrication oil or any other flammable fluids/materials follow the same engine shutdown cooling procedure.

5) It is recommended that insulation of the catalytic converter be considered to minimize risks due to potential fire and burn hazards. It is very important to keep the insulation materials clean, dry and free of absorbed fuel and lubrication oils in order to prevent potential fire.

6) Use a U.S. Forestry Service approved spark arrestor installed after the catalytic converter to prevent the ignition of flammable materials by sparks emitted from the catalytic converter. In addition we recommend that a muffler be used after the catalytic converter where applicable.
