• Read the temperature display and pres-
sure gauge to ensure the system is
pressurized. Lift the relief valve top lever
slightly, allowing water to relieve through
the valve and discharge piping.
• 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 lever again to
attempt to clean the valve seat. If the
valve does not properly seat and contin-
ues to weep afterwards, contact a quali-
fied service technician to inspect the
valve and system.
• If the water does not flow from the valve
when you lift the lever completely, the
valve or discharge line may be blocked.
Immediately shut the unit down per the
instructions below. Call a qualified ser-
vice technician to inspect the valve and
system.
