8. Use the transfer handle to move the main contacts in the
transfer switch to the UP (utility position). Switch the 2-pole
breaker ON in the distribution panel.
9. Now switch the generator's main breaker ON, and put the
mode switch in AUTO.
10. Shut OFF utility power and make sure the generator starts
automatically.
11. If everything worked properly, switch the main breaker to ON
and make sure that power is automatically transferred back to
the utility.
12. After the engine has completed its cool down cycle and shut
down, shut OFF utility power again.
When the generator is supplying power to the transfer switch,
move the breakers in the switch to the ON position, one at a
time, until the generator has accepted the entire priority load.

13. With the generator carrying the entire priority load, recheck
gas pressure to verify that it is at the same level it was before
the generator was started.
Even if the generator is running smoothly at this point, a drop
in gas pressure indicates that the supply is barely adequate to
supply the generator's needs. Changes in the generator load, or
additional gas demand by other appliances may affect the gen-
erator's performance. Verify gas pressure and pipe sizing. Turn
off the gas, unhook the manometer and reinstall the port plug.
14. Switch the main breaker ON to restore utility power.
The generator will continue to run to allow the engine to cool
down before shutting itself off.
Shut off utility power again. The generator should start and the
entire priority load should transfer to the generator.
Close the main breaker to restore utility power and allow the
engine to cool down and shut itself off.
