Exhaust System Safety.16-17 - Generac Power Systems NP Series Installation Manual

EXHAUST SYSTEM SAFETY
Maintain a clearance of at least 3 inches (76mm)
between exhaust system parts and any combustible
material (such as wood, felt, cotton, organic fibers or
other like material). If you cannot maintain the 3-inch
clearance, locate, insulate or shield the exhaust part(s)
so that the temperature of any combustible material is not
raised more than 117°F (65°C) above the ambient air
temperature.
Terminate the exhaust tailpipe such that exhaust gases
will not be drawn back into the generator compartment
and recirculated.
If there is any possibility of the tailpipe or muffler being
damaged, protect these damage prone areas by means
of a protective device (such as a "skid bar").
Install the generator exhaust system according to safe
automotive practices.
• Use exhaust system parts recommended by
Generac. Using unapproved exhaust mufflers
and exhaust system parts is the responsibility of
the person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under the
vehicle.
• , Do not terminate the exhaust system under any
opening, window or vent which can be opened or
is not permanently sealed from the vehicle interi¬
or.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator
engine.
• Never tee the generator engine exhaust pipe into
the vehicle engine exhaust piping. This causes
excessive back pressure on the generator
engine. Also, water from one engine can damage
the other engine.
• Plan exhaust system installation carefully.
Comply with all applicable codes, standards and
regulations.
Use enough exhaust system hangers to prevent
any part or the system from being dislocated.
