Section 2 – Installation

QUIETPACT™ 75D Recreational Vehicle Generator

2.5EXHAUST SYSTEM

The generator exhaust system must be safely and properly installed. Only approved exhaust system parts must be used. A properly installed exhaust sys- tem must be vapor-tight, quiet, and completely safe.

DANGER

The generator engine gives off DEADLY carbon

!monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concen- trations, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED. SYMPTOMS OF CARBON MONOX- IDE POISONING ARE (a) inability to think coher- ently, (b) vomiting, (c) twitching muscles, (d) throbbing temples, (e) dizziness, (f) headaches,

(g) weakness, and (h) sleepiness. IF FEELING ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP. Do not operate the generator until its exhaust system has been inspected and properly repaired.

Never tee the generator engine exhaust pipe

!into the vehicle engine exhaust piping. This causes excessive back pressure on the genera- tor engine. Also, water from one engine can damage the other engine.

2.5.2 EXHAUST SYSTEM SAFETY

Maintain a clearance of at least 3 inches (76 mm) between exhaust system parts and any com- bustible material (such as, wood, felt, cotton, organic fibers, or other like material). If the 3-inch (76 mm) clearance cannot be maintained, locate, insulate, or shield the exhaust part(s) so that the temperature of any combustible material is not raised to more than 117° F (65° C) above the ambient air temperature.

Terminate the exhaust tailpipe at least 3 feet (91 cm) from the vehicle’s fuel filler cap and at least 2 inches (51 mm) past the outer edge of the vehi- cle. Do not terminate the exhaust system under the vehicle.

Terminate the exhaust tailpipe such that exhaust gases will not be drawn back into the generator compartment and recirculated.

Fuel and oil must NOT be able to drip onto any exhaust system part.

2.5.1 MUFFLER AND SPARK ARRESTOR

The exhaust muffler supplied with the QUIETPACT ™ 75D is a spark arrestor type that meets code and standard requirements of the U.S. Forest Service. Any person(s) installing an unapproved muffler, or an unapproved exhaust system part, or modifying an exhaust system in any way that might cause a hazard, is liable for any damage, injury, or warranty expense that might be caused by such unapproved installation or modification.

MUFFLER PERMANENTLY

MOUNTED INSIDE

ENCLOSURE

TAILPIPE MUST EXTEND 2 INCHES

BEYOND THE COACH BODYWORK

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 enough exhaust system hangers to prevent any part of the system from being dislocated.
