Exhaust
System
GENERAL
Plan each individual exhaust system carefully.
A
proper
installation
is
not
only
vapor-tight,
but
usually quieter
and safer too. Be sure to check all applicable standards,
local codes and regulations.
Refer to the following
text
for recommendations to fol-
low when installing the exhaust system. Then refer
to
the installation instructions supplied
with
the exhaust
system
kit
for
specific mounting procedures.%ee

MUFFLER RECOMMENDATIONS
Onan supplied mufflerispark arresters are
forest
ser-
vice approved and meet code requirements. (Failure
to
provide and maintain a sparkarrester can be
in
violation
of
the
law.)
Use
only
ONAN
UL/CSA tested
mufflers.
Liability for damage or
injury
and warranty expenses
dueto use
of
unapproved mufflers
or
installation modifi-
cations becomes
the
responsibility of the person instal-
ling

or
performing the modifications.
Contact an Onan distributor for approved exhaust sys-
tem parts and installation instructions.
EXHAUST INSTALLATION
GUl
DELlN
ES
The exhaust system
must
be no closer than
3
inches
(76
mm)
from combustible material (wood,
felt,
cotton,
organic fibers, etc.),
or
be
so
located, insulated
or
shielded, that
it
does not raise the temperature of any
combustible material more than
117OF
(65OC)abovethe
ambient air inlet temperature.
The
exhaust
system
must
extend a
minimum
1
inch
(25
mm)
beyond the perimeter of
the
vehicle.
If
the generator
set tailpipe
is
on the same
side
of the coach as the
compartment.
try
to
terminate the tailpipe aft of
the
generator set air intake to reduce the
possibility
of
exhaust recirculation,
by
directing
the
exhaust down
and to the rear.
Exhaust gas presents the hazard of
severe personal injury
or
death. Use
only Onan specified exhaust equipment with generator
set and support the system per
kit
instructions.
Exhaust gas presents the hazard of
iAWARNiNG

severe personal inibry or death.
Do
not terminate exhaust gas under vehicle.
Do
not termi-
nate exhaust system directly under any vent, window,
or opening which can be opened and which is not
pennanenily sealed from the vehicle living space. Keep
all openings closed when the generator set is running.
Excessive exhaust back
pressure
can cause engine damage. If tai/pipe
deflector is
used,
make sure it is large enougb to pre-
vent back pressure.
Water vapor can cause engine dam-
-/
age. Do not connect the generator set
exhaust to the vehicle exhaust .system since water
vapor from one engine can damage the other.
TAILPIPE RECOMMENDATIONS
An
exhaust tailpipe
is
NOT
supplied because of varia-
tion
in
length requirements between motor home manu-
facturers. After muffler
is
installed and
prior
to installing
exhaust tailpipe, refer to
the
following recommenda-
tions
for additional
tips
and safety considerations.
Use
1-318
inch
I.D.
18
gauge
rigid
steel
tubing
for
tailpipe.

Exhaust gas presents the hazard

Do
not use flexible exhaust tailpipe since it can leak or
break due to road shock or vibration.
Do
not terminate
exhaust sysiem under the vehicle. Direct exhaust
gases away from any window, door, or compartment
openings.
Do
not operate the generator set without an
exhaust tailpipe.
Use U-bolt type automotive muffler clamps marked

and double rubber, U-shaped shock
mounted
hangers for supporting the exhaust system.
If
tailpipe
extends beyond
1-1
/2
feet
(0.46
m)
from muffler. attach
an automotive tailpipe hanger for additional support
The exhaust system should be supported at or near the
perimeter of the vehicle to prevent the pipe from being
damaged and pushed
up
under the
skirt.
Angular mounting of muifier and tail-
exhaust system damage. Properly mounted hanger
brackets wili absorb much road
shock
vibration and
prolong the usefulness of exhaust system components.
Mount muffler and iailpipe hanger brackets directly
above the component supported, not at an angle.
Do
not
twist the rubber sections of any hangers.
