MECHANICAL INSTALLATION — EXHAUST SYSTEM

„Thermally insulate exhaust piping and mufflers as required to prevent burns from accidental contact, prevent activation of fire detection devices and sprinklers, reduce corrosion due to condensate, and reduce the amount of heat radiated to the generator room.

Engine exhaust manifolds and turbocharger housing, unless approved by the engine manufacturer, must never be insulated. This can result in material temperatures that can destroy the manifold and turbocharger.

„Exhaust piping must be routed at least 12 inches (305

mm)from combustible construction. Use approved thimbles where exhaust piping must pass through combustible walls or ceilings.

„Exhaust pipe (steel) expands approximately 0.0076 inches per foot of pipe for every 100°F rise in exhaust gas temperature above room temperature (1.14 mm per 100°C rise). It is recommended that flexible, corrugated stainless steel tubing be used to take up expansion in long, straight runs of pipe.

„Horizontal runs of exhaust piping should slope downwards, away from the engine, to the outdoors or to a condensation trap.

„A condensation drain trap and plug should be provided where piping turns to rise vertically. See Figure 15.

„A rain cap should be used if the exhaust outlet is vertical.

„The exhaust system must terminate outdoors at a location where engine exhaust will disperse away from buildings, animals, and building air intakes. In addition, the exhaust must not be allowed to blacken walls or windows with soot.

„It is highly recommended that the exhaust system be carried up as high as practical on the downwind side of buildings and that it is discharged straight up to maximize dispersal.

Figure 15. Condensation Trap

Some codes specify that the exhaust outlet terminate at least 10 feet (3 meters) from

NOTEthe property line, 3 feet (1 meter) from an exterior wall or roof, 10 feet from openings into buildings, and at least 10 feet above the adjoining grade.

Exhaust back pressure must not exceed the allowable back pressure of the engine. Excessive exhaust back pressure reduces engine power, engine life, and may lead to high exhaust temperatures and smoke.

Exhaust pipes are very hot and they can cause severe personal injury or death from direct contact or from fire hazard. Shield or insulate exhaust pipes if there is danger of personal contact or when routed through walls or near other combustible materials.
