combustion air pipe and exhaust pipe should be kept in good
condition. Do not damage or remove them.
Both the combustion air pipe and exhaust pipe should come downward from
the heater and face opposite to the vehicle’s direction of travel. If the pipe
cannot avoid a curve, make sure the radius is no smaller than 50mm and the
sum of all curves does not exceed 270˚. Figure XIII shows the right and wrong
way to install the combustion air intake. Note that it is the same for the
exhaust too.

When the heater is operating, the exhaust will
get hot, so make sure it is installed away from
any parts that could get damaged by high
temperatures. The exhaust vent should also
point downward to the road surface with an
angle of 90˚±10˚. This is best achieved by fixing
a clamp 150mm from the pipe end.
Any exposed exhaust should be covered with a
heat shield to prevent scalding.
