Exhaust System
Exhaust System Safety Information
WARNING
Do not direct the exhaust outlet toward
highly flammable or heat-sensitive parts.
Failure to do so can cause a fire.
WARNING
Protect vehicle components in the vicinity
of the exhaust system from overheating by
implementing the following measures:
•
Maintain minimum safety distances.
•
Ensure adequate ventilation.
•
Use fire-resistant materials or heat
shields.
•
Always comply with any applicable legal
requirements.
WARNING
Exhaust pipes must not be routed through
the interior of the vehicle.
Exhaust has must be routed outside of, and
beyond the edge of the vehicle. Failure to
do so can cause exhaust gas to leak inside
of the vehicle causing illness and death.
The exhaust pipe (inside diameter 0.86” (22 mm) can
be routed with several bends; not to exceed a total
of 270°, minimum bending radius 2” (50 mm). The
total line length must be between 1’ 6” and 3’
3” (0.5 and 1m).
An optional muffler can be installed near the heater.
The exhaust pipe opening must be located so that it
cannot become clogged with snow or dirt. The ex-
haust outlet must be unobstructed and must not be
directed at vehicle parts.
The muffler and the exhaust pipe must not be
fastened to temperature-sensitive vehicle parts. Suffi-
cient spacing (at least 0.8” (20mm) to temperature-
sensitive components must be ensured. Thermal in-
sulation of the exhaust pipe is permissible.
It is also recommended to route the exhaust pipe
with a downhill gradient. If this is not possible, con-
densation drain holes 0.16” (4 mm) diameter can be
drilled at the lowest point(s).
NOTE
The opening of the exhaust pipe must not
point in the direction of travel.
To ensure that the exhaust pipe opening is posi-
tioned at an angle of 90° ± 10° to the road surface, a
fastener must be mounted at a distance of less than
6” (150 mm) from the end of the exhaust pipe. If the
vehicle is equipped with an underbody shield, the
exhaust pipe must be extended by an additional 0.4”
(10 mm).
Rigid pipes comprised of stainless steel with a min-
imum wall thickness of 0.04” (1mm) or flexible
piping of the same material must only be used as ex-
haust pipe. The exhaust pipe is secured to the
muffler using supplied exhaust clamps.
