Exhaust gas piping
Regulation!
• The outlet must be implemented in such a way that insertion
of a 16 mm dia. ball is not possible.
• Exhaust pipes must be laid in such a way that there is no
likelihood of any exhaust gases entering the vehicle interior.
• The functioning of parts of the vehicle which are important
for its operation must not be impaired.
• It must not be possible for condensate or water to collect
in the exhaust gas line.
Drain holes are permitted. These must convey the fluid
through the interior in sealed pipes to the outside.
• The exhaust pipe opening should face upwards or to the
side or, if the exhaust piping is laid below the floorpan of
the vehicle, it should extend to near the side or rear of the
driver‘s cab or vehicle.
Danger of combustion and poisoning!
• Whenever combustion occurs high temperatures and
exhaust gases with toxic elements are generated.
- Do not perform any work on the exhaust gas piping while
the heater is on.
- If any work needs to be done to the exhaust gas piping,
switch off the HYDRONIC, wait until all components have
completely cooled and, if necessary, wear protective
gloves.
- Do not breathe in any exhaust gases.
Fitting exhaust gas piping
The exhaust gas piping can be laid out as shown below. See
also page 20, Diagram 14:
• Exhaust pipe connection, bent by 60º, dia. = 70 mm
• Exhaust pipe connection, dia. = 70 mm
• Exhaust pipe bend, dia. = 70 mm
• Rigid exhaust pipe from unalloyed or alloyed steel,
dia. = 70 mm, length max. 4 m, wall thickness min. 1 mm
Also required:
1 exhaust pipe bend, dia. = 70 mm
1 end sleeve
• Flexible exhaust pipe out of alloyed steel
dia. = 70 mm, length max. 4 m
Also required:
1 end sleeve
Attach the exhaust pipe with pipe clips to the floorpan of the
vehicle in suitable places.
Mount an end sleeve with crossbars on the exhaust pipe.
The exhaust gas piping can be bent a max. 3 x 90°, in which
case the overall length is reduced by 0.5 m for each 90°
bend.
To enable the condensate to flow out, drill a hole 5 mm dia. at
the lowest point on the exhaust gas piping.

End sleeve with crossbars
Important!
• The entire exhaust gas piping is very hot both during and
immediately after operation of the heater.
- Mount exhaust pipe with sufficient separation away from
parts which are sensitive to the heat.
- In particular, look out for fuel lines (plastic or metal),
electric lines and brake hoses.
- Exhaust pipes must be securely fastened (with a
recommended standard distance 50 cm) in order to avoid
damage through vibration.
- Lay the exhaust gas piping so that the exhaust gases are
not drawn in directly as combustion air.
- When installing the HYDRONIC in a case and with a short
exhaust pipe, the exhaust gas piping must run to the
outside through the bottom of the case.
- The functioning of parts of the vehicle which are important
for its operation must not be impaired (take care to allow
sufficient separation).
- The opening of the exhaust gas pipe must not be allowed
to become clogged up with dirt or snow.
- The opening of the exhaust gas pipe must not be pointing
in the direction of travel.
Please note!
• The rigid exhaust pipe and the flexible exhaust pipe are
currently not included in the Eberspächer scope of supply.
If required, these exhaust pipes must be obtained from a
specialist shop.
• If necessary, you can make the end sleeve with crossbars
(out of metal) for the exhaust pipe yourself (see diagram).
