The intake and exhaust pipe shall be arranged so that the pipe
will not be blocked by mud, rain, snow and other objects.
3.5.8
When the heater is operating, the temperature of the exhaust
pipe is very high. The exhaust pipe should be placed away from
non-heat-resistant parts. The exhaust outlet shall point
vertically downward with an angle of 90 °± 10.
3.5.9
A heat shield should be installed if there is risk for people to
touch the exhaust pipe.
3.5.10
The air intake pipe and exhaust pipe shall always bend
downward. Otherwise, a
φ
5mm condensate drain hole shall be
opened at the lowest point of the pipe. If bending is required,
the bending radius of the pipe shall not be less than 50mm. In
addition, the sum of all bending angles shall not exceed 270°.
Note: Turning off the heater directly by cutting off the power is
strictly prohibited. It could cause carbon build-up in the burner and
damages to the accessories.
