that do not meet our quality standards (especially
wind resistance, pipe diameter and number of ripples)
shall not be used. If the warm air duct must withstand
a considerable amount of bending immediately after the
hot air outlet of the heater in a limited space, we
recommend using a 90° elbow (Figu re 3-37). This elbow
can be connected to a diameter of mm hot air duct.
In the case where the length of the pipe is less than
2 meters, the air outlet cannot be installed at a
height higher than the connection of the warm air
duct. When the pipe length is less than 50cm, the pipe
must be siphon between the connector and the outlet.
These measures prevent the undesirable heating caused
by (fairing effect) convection of the vehicle during
summer operation.
★The warm air pipe must be firmly inserted into the
connection port.
To get the best warm air distribution, Belief
recommends using 4 warm air outlets for the heater.
If only three warm air outlets are required, then a
lower warm air outlet must be selected to seal.
★ The cross section of the heat er duct must not be
reduced due to pipe connections or the analogue.
Gas Connection
The heater operating pressure must be in compliance
with a 30 Mbar liquefied gas supply.
When the gas pipe is cut off, clean the port flash and
burrs.
The paving of the pipe must make the heater easy to
disassemble for maintenance work.
Use high-pressure air to purge internal debris before
installing the gas pipe.
The turning radius of the gas pipe is not less than
R50, and it is recommended to use elbow pipe to pass
the joint of right angle.
★ The gas interface (Figure 13 -2) cannot be truncated
or bent.
Before connecting to the heater, make sure that the
gas line is free of dirt, shavings, etc.
The gas system must comply with the technical,
administrative, and legal regulations of the country.
Anti-collision safety valve (optional)
To ensure safety during driving, it is recommended to
install a crash safety valve that must be installed
after the liquefied gas tank regulator. when Impact,
tilting, the anti-collision safety valve automatically
cuts off the gas line.
Connecting Water Pipe
The water tank can be supplied with a pressure pump or
immersion pump with a pressure of 2.8 bar.
If the tank is connected to a centralized water supply
(rural or urban connection), or if a high-pressure
pump is used, a pressure reducer must be used, which
will prevent pressures above 2.8 bar.
★ The temperature rises and expansion of the water
before the pressure relief valve is triggered may
