SCOPE! This task checks the closure tightness of a gas safety shutoff valve and should be performed by qualified personnel during the initial startup of a burner system, at least annually thereafter, and whenever the valve or valve bonnet is replaced

PREREQUISITES! Prior to performing the valve leak test, and with the appliance running, apply an all-purpose liquid leak detector and bubble test all gas train components and fittings downstream of the main shut-off valve (G). The presence of bubbles indicates a leak. Tighten the fittings before proceeding

Disable the burner system and make sure the safety shut-off valves are closed via the visual indicators

Close the upstream shut-off valve (G) and both downstream manual test ball valves (L)

Remove the cap on the valve 1 test port (H) and connect the test apparatus to the test port

Open the upstream shut-off valve (G)

Allow some time for potential leakage to charge the plumbing before measuring the valve seat leakage
