Gas-flow monitor
function test
The functionality of the gas-flow
monitor is directly related to how
the gas pipe was installed. For
this reason, it must be checked
individually for every type of
vehicle. This test is therefore a
permanent part of the design
procedure! We also recommend
a function test as part of series
production in order to counter-
act negative effects caused by
any changes to the installation
procedure.
– Open all stop valves.
– Unscrew the first heating unit
from the line and seal off the
line temporarily.
– Bring the gas system into
operation (see “Operating
instructions”).
– Open the temporary seal. Gas
may flow out for only a short
time until the gas-flow monitor
is triggered.
– Screw the heating unit to the
gas line.
– If you have more than one
heating unit, you must
perform the test separately for
each one!
– Conduct the leak test (see
“Checking the low pressure
area for leaks”).
