Choosing and fitting
Relief safety valves of this kind are chosen by set pressure, connection size, and body material; the set pressure may be adjustable or factory-set and is usually stated on the label. Before ordering, confirm the connection thread and the pressure setting from the existing valve. Install the valve upright, and route the vent line safely outdoors in accordance with applicable standards. The valve is not a shut-off or metering device; it acts independently of the burner control.
Signs of failure
Typical failure involves contamination on the seat causing leakage, or the valve opening at an incorrect pressure. This may be noticed as gas odor or unstable downstream pressure. Regular inspection should confirm the seat is clean and the valve opens at the correct pressure without leaking.
