Installation
39

It is recommended to assemble a flame arrester before the electronic flow regulator.

For the pressure of the gas out of the gas pressure regulator, the value should be in
3~5kPa.
3.8.1 Gas line

The lines installed before the gas pressure regulator should be the tough line, also the
flange or the threaded line can be used to connect.

Hoses can only be used after the gas pressure regulator, the inner diameter should be
≥
40mm.The length of this hose should be
≤
1m.

The dust inside the lines should be purged out with compressed air before installing. The
line and hose can't be scratched or crushed.

Minimize the number of connection points on the high pressure pipeline and guarantee
the easy-to-check construction, proper sealing, and high reliability.

The high pressure pipeline shall be provided with an upstream protection device to cut off
the gas when the engine is stopped or gas is leaking.

Test connection points with leakage detecting liquid under the rated gas working pressure,
and no bubble detected within 1 minute. Alternatively, check with a gas detector with at
least 25ppm measurement accuracy.
3.8.2 Gas filter

The proper working temperature range for this filter is -15
℃～
60
℃
.

The gas inlet pressure of the filter should not exceed the technical requirement.

The inspection, cleaning, and replacement of the filter should be easy to do after
installing.

Refer to the mark on the filter to ensure right installing position.
3.8.3 Gas pressure regulator

The proper working temperature for the regulator is -15
℃～
60
℃
.

The distance from the regulator to the engine should be
≤
2m.

The regulator vibration level should be lowest.

The regulator should be installed after the filter.

The regulator should be installed properly to avoid to be polluted by the dust during using.
