Combustion air piping
Regulation!
• The necessary combustion air must be drawn from the
outside.
• The combustion air inlet must be implemented in such a
way that insertion of a 16 mm dia. ball is not possible.
Please note!
• When laying the combustion air piping the following should
be noted:
- The combustion air inlet must always be uncovered.
- Lay the combustion air inlet so that exhaust gases are not
drawn in directly as combustion air.
- Do not position the combustion air inlet so that it faces the
vehicle‘s air stream.
- Combustion air inlet must not be allowed to become
clogged up with dirt or snow.
- Any water that has penetrated must be able to drain off.

Combustion air intake when the HYDRONIC is installed
in a case
When installing the HYDRONIC in a case, it is recommended
that a hood with hose connection is mounted to draw in the
combustion air.
The combustion air is then drawn in outside of the case via
a flexible hose.
In this way it is possible for the combustion air to be drawn
from an area where the temperature is within the permitted
range and protection is provided against dirt accumulation.
Place a protective grille on the flexible hose. If the hood with
hose connection is not used, the combustion air must be
drawn in through an air vent with an effective minimum cross-
section corresponding to a pipe of 60 mm dia.
Please note!
• The air vent for the combustion air must be positioned on
the case in such a way that
- it cannot become clogged up with dirt or snow
- exhaust gases cannot be drawn in.
