When installing the exhaust pipe, make sure
that no exhaust gases enter the interior or are
drawn in by the fan through the cab heater
radiator.
At the end of the exhaust pipe a shield is
installed, which necessary for stable operation
at low heating modes (Fig.14).
In absence of the screen, air will be blown back into
the exhaust pipe. This leads to increased heater shooting
and impairs heat capacity.Exhaust gases have to be
removed outside of the vehicle
Exhaust gases must not hinder operation of other vehicle
units.Exhaust gases should be discharged to the outside.
Furthermore, the gases should not adversely affect the operation
of vehicle units. The outlet of the exhaust pipe should be in such
a position that would prevent clogging or entering of snow, and
also provide for free drain of any water that got into it.
Heaters are equipped with a muffler attached to the
exhaust pipe. Depending on the mounting location of the
muffler, cuts are made to the exhaust pipe. For better fixation
of the exhaust pipe on the fittings of the muffler, it is necessary
to make cuts 15-20 mm in length, but not extending beyond the
male fittings of the muffler. Installation of the muffler is shown
in Fig.15.
