Operate boiler relief valve
1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge,
avoiding any possibility of scalding from hot water.
To avoid water damage or scalding due to valve operation, a metal discharge
line must be connected to relief valve outlet and run to a safe place of disposal.
This discharge line must be installed by a qualifed heating installer or service
technician in accordance with the instructions in the
Boiler manual . The
discharge line must be terminated so as to eliminate possibility of severe
burns should the valve discharge.
2. Read the boiler pressure/temperature gauge to make sure the system is pressurized.
3. Lift the relief valve top lever slightly, allowing water to relieve through the valve and discharge
piping.
4. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief
valve discharge pipe to ensure that the valve does not weep after the line has had time to drain.
If the valve weeps, lift the seat again to attempt to clean the valve seat. If the valve continues to
weep afterwards, contact your qualified service technician to inspect the valve and system.
5. If water does not flow from the valve when you lift the lever completely, the valve or discharge
line may be blocked. Immediately shutdown the boiler, following the instructions on the
inside jacket top Lighting Instructions. Call your qualified service technician to inspect the
boiler and system.
