Operate Pressure Relief Valve
• Before proceeding, verify that the relief valve 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 relief valve operation,
a discharge line must be connected to the valve outlet and
directed to a safe place of disposal. This discharge line must be
installedbyaqualiedservicetechnicianorheating/plumbing
installer in accordance with the appliance installation manual.
The discharge line must be terminated so as to eliminate
possibility of severe burns or property damage should the valve
discharge.
• Read the temperature and pressure gauge to ensure the
system is pressurized. Minimum is 10 psi. Maximum is
145 psi. Lift the relief valve top lever slightly, allowing
water to relieve through the valve and discharge piping.
• Ifwaterows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
hard time to drain. If the valve weeps, lift the lever again
to attempt to clean the valve seat. If the valve does not
properlyseatandcontinuestoweep,contactaqualied
service technician to inspect the valve and system.
• Ifwaterdoesnotowfromthevalvewhenyoucompletely
lift the lever, the valve or discharge line may be blocked.
Immediately shut the appliance down per instructions on
page2 andcallaqualied servicetechniciantoinspect
the valve and system.
