EXHAUST
SYSTEM
The condition of the exhaust system is extremely
critical on
RV
generator sets because of the possibil-
ity of exhaust gases entering the coach.
The exhaust system must be serviced immediately
if
inspection
reveals leaking joints or connections, loose fasteners, or broken or
damaged components.
Always replace worn components with new original
equipment replacement parts.
Do
not attempt to
repair a broken exhaust pipe or manifold by welding
and do not replace worn out components with parts
that do not meet factory specifications.
Exhaust presents the hazard of
k%!@!&l
severe personal injury or death.
Modifying the exhaust system mlght allow poisonous
exhaust gases
to
enter the coach. Use only original
equlpment replacement parts when servlclng the
exhaust system. Unauthorized modiflcaflons willalso
void the warranty and cancel the
UL
Llst/ng/CSA
Cerflflcatlon. Llabl//ty for injury or damages due to
unauthorlzed modiilcations becomes the responsi-
billfy of the person making the change.
Two basic exhaust systems are used with Emerald
series generator sets. Figure
6-1
shows a typical
exhaust system for conventional compartment
mount generator set. Figure
6-2
shows a typical
exhaust system for an underfloor mount generator
set. Separate sections cover the service procedures
for each exhaust system.
