Note pressure gauge installed by drilling and tapping the T fitting and using a small valve. This allows
removal of the gauge to prevent freezing damage to the gauge.

Following is an example of what

NOT

to do for a Stream Engine installation. An installation of this sort

will result in a huge loss of power. To optimize the output of the generator all aspects of installation
should be well done. It is important to pay attention to plumbing, nozzle size, intake conditions, siting,
electrical components, as well as regular maintenance.

WRONG

: 90° bends in undersized line

Do NOT install a stream engine in this manner

WRONG

: Same undersized line for both nozzles

WRONG

: Valve smaller than pipeline
