OPERATION
WARNING
Explosion Hazard and Electrical Shock Hazard.
Can cause explosion, serious injury or death.
• Do not allow fuel to accumulate in the combustion
chamber for longer than a few seconds without igniting.
An explosive mixture can result.
• Do not put the system into service until you have
satisfactorily completed the following Valve Seat Leak
Test, all applicable tests described in the Checkout
section of the flame safeguard control manual, and any
other tests required by the burner manufacturer.
• All tests must be performed by a trained, experienced
combustion service technician.
• Close all manual fuel shut-off valves as soon as trouble
occurs. After the installation is complete, perform the
Valve Seat Leak Test before putting the valve into service.
A. Valve Connection and Accessory Leak
Test
IMPORTANT
Leak check should be performed only by trained, experienced
combustion service technician during the initial startup
of the burner system, or whenever the valve is replaced.
It is recommended that this test also be included in the
scheduled inspection and maintenance procedures.
B. Valve Seat Leak Test (Refer to Fig. 35)
IMPORTANT
This is a test for checking the closure tightness of the gas
shut-off valve. It should be performed only by trained,
experienced combustion service technicians during the
initial startup of the burner system or whenever the valve
is replaced. It is recommended that this test should also
be included in the scheduled inspection and maintenance
procedures. Refer to Fig. 35.
