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
