4.4 Connecting the Gas Lines to the BIOGAS 3000

Note: The gas connections on the system are ¼ inch stainless steel
bulkhead connectors with a compression fitting suitable for ¼ inch outer
diameter tubing. It is recommended that stainless steel tubing be used
where possible.

Note: After installation, ensure all tube connections are tight and free
from leaks. See section
Pressure Test .
Gas Sample Lines
4.4.1
Care should be taken in routing the sample lines, especially in cold
environments. The sample lines may need insulating or even trace heating to
prevent freezing of water within the pipe. This is not part of the BIOGAS 3000
system and is the responsibility of the operator.

The sample should be taken from a suitable location at the required
monitoring point. It is recommended that a valve be incorporated in the
assembly so that the gas can be shut off if the sample line is removed.


The line should connect to the upper surface of a horizontal pipe or on
a vertical standing pipe. This will prevent excessive amounts of water
entering the sample line.
