3‐4 Receiving & Installation MN2408Hot Exhaust GassesWARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Neverbreath exhaust fumes produced by a running engine. Only run the engine outdoors whereventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless andextremely dangerous gas that can cause unconsciousness or death. Symptoms of carbonmonoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting orincoherence. If you or anyone else experiences these symptoms, get out into fresh airimmediately. Stop the engine and do not restart the engine until it has been inspected and ifnecessary repaired or reinstalled in a well ventilated area.WARNING: Hot exhaust gasses must never be directed toward anything that may catch fire or explode.It is extremely important to discharge engine exhaust gasses away from the engine and out ofthe building. If these gasses remain in the cylinder, poor performance or eventual engine damagemay result. This condition results from excessive back-pressure, which could be caused by anyone or a combination of the following conditions:1. Exhaust pipe too long or the diameter is too small.2. Excessive number of sharp bends in the exhaust system.3. Obstruction in the exhaust system.Backpressure must not exceed 20” of water column.The direction of the discharged hot air and hot exhaust gases is important as they have thepotential to create brown spots on the lawn or adjacent structures. In extreme cases thisextremely hot air could cause dried grass or other debris to ignite.Exhaust lines should be as short and straight as possible. Long pipe lengths and elbows tend toresist the flow of gases and accumulate carbon deposits. Each pipe fitting and elbow will furtherrestrict the exhaust flow.Guidelines for Exhaust System1. If you are using a remote muffler it should be mounted as close to the engine aspossible, since it will clog with carbon if it's operating temperature is too low.2. If you are using a remote muffler a flexible coupling of 12” or more must be installedbetween the exhaust line and the manifold to absorb the engine's vibration. However,a short, solid section of pipe between 6” and 8” long should be placed between theconnection of the manifold and the flexible coupling. This nipple will reduce thepossibility of the hot gases burning up the flexible coupling.3. It is extremely important that you do not allow the hot exhaust gases to re-circulate intothe engine's cooling air intake.4. Water is one by-product of combustion and is present in the exhaust pipes or muffler.This water must be kept from draining back into the engine. This can be done byslanting the horizontal section of the exhaust system piping downward slightly, awayfrom the engine. A water trap consisting of a tee extension with a drain cock shouldalso be provided. This water trap should be located between the flex coupling and themuffler, but as close to the engine as possible on a horizontal section of the exhaustpiping.5. It is also recommended that an exhaust rain cap be used whenever it is possible thatrain could get into the system. This will help to prevent corrosion and damage to theexhaust system and engine.6. The exhaust system is subject to the engine's vibration and it must therefore be solidlysecured to reduce mechanical stress and the potential for breakage.7. The engine's exhaust system is the hottest component of the installation and extremecare and considerations must be given to it.
