g. Re-fit the water governor.

h. Re-connect the burner supply pipe.

i. Test for gas soundness as follows:-

- Ensure the water service cock is in the OFF position, this will ensure that water CANNOT

flow and open the automatic valve.

- Turn ON the gas, purge and light the pilot, this will pressurise the burner supply pipe.

- Test the burner supply pipe joints for gas soundness using leak detection fluid.

j. Re-assemble remaining parts and ensure the water service cock is in the ON position.

IMPORTANT: If the automatic valve and burner manifold complete is dismantled, it can

only be tested for gas soundness under pressure AFTER blanking off all the injectors.
