Fig. 6. Installing a 4 in. V5055 Valve.

CAUTION

Equipment Damage Hazard.

Operation without proper checkout can damage 

the equipment.

1. Do not put the system into service until you have 

satisfactorily completed the following Valve Leak 

Test, all applicable tests described in the Checkout 

section of the Instructions for the flame safeguard 

control, and any other tests required by the burner 

manufacturer.

2. All tests must be performed by a trained, 

experienced flame safeguard control technician.

3. Close all manual fuel shutoff valves as soon as 

trouble occurs.

After the installation is complete, cycle the valve several times 

with the manual fuel shutoff cock closed. Make sure the valve 

and actuator function properly. Also perform the Valve Leak 

Test that follows before putting the valve into service.

Valve Leak Test (Fig. 7)

This is a test for checking the closure tightness of a gas 

safety shutoff valve. It should be performed by qualified 

personnel during the initial startup of a burner system, or 

whenever the valve or valve bonnet is replaced (see 

Service Information section). It is recommended that this 

test also be included in the scheduled inspection and 

maintenance procedures. For a periodic inspection test, 

follow steps 1, 3, 4, 5, 8, 9, 10, 12, 13, 16, and 17.

1.

De-energize the control system to assure that there is 

no power to the safety shutoff valve (

C

) shown in Fig. 7.

2.

Close the upstream manual gas cock (

A

).

3.

Make sure the manual test petcock (

F

) is closed in the 

leak test tap assembly (
