Exhaust System Installation
A proper exhaust system installation will ensure safe working
conditions and maximum engine efficiency. All MQ Power-
MQP Series, standby, engine-generators have factory-
designed mufflers, exhaust connectors and rain caps
available for each model. For best performance and ease of
mounting, it is recommended the factory components be
used whenever practical. Refer to Table 17 on page 49 for a
complete listing of factory recommended exhaust silencers
for each model. A properly installed exhaust system routes
engine exhaust to a safe location where the exhaust can
dissipate with fresh air. The exhaust system disperses engine
exhaust fumes, soot, and noise away from people, vents
and buildings. It is essential to the performance of the engine-
generator set that the installed exhaust system does not
exceed the engine manufacturer’s maximum exhaust
backpressure limit. Pressure drop of an exhaust system
includes losses due to piping, silencer and termination. High
backpressure can cause a decrease in engine efficiency or
increase in fuel consumption, overheating, and may result
in a complete shut down of the engine-generator. Potential
damage could result. Refer to Table 17 on page 49 for back
pressure limits for each model generator set.

All work should be completed by qualified persons familiar
with the installation, construction and operation of generator
sets. All work should be completed in accordance with the
National Fire Protection Association (NFPA), Uniform Building
Code (UBC) and other state or local codes.
Some generators require little or no engine exhaust
component installation. In most cases, if the generator set
is equipped with a manufacturer’s installed, weather
protective enclosure, the engine exhaust system is generally
already mounted and plumbed within or on top of the
generator enclosure. There is little or no site work that has
to take place. Check with the engine-generator manufacturer
for specific details.
Inhalation of exhaust gases can result in
severe personal injury or
death!
Use extreme care during installation to
provide a tight exhaust system. Terminate
exhaust pipe away from enclosed or
sheltered areas, windows, doors, and vents.
Weight applied to the engine manifold can result in
turbocharger damage. Support the muffler and exhaust piping
so no weight or stress is applied to the engine exhaust elbow.
DO NOT use exhaust heat to warm a room, compartment,
or storage area.
