1. Inspect the relief valve and li the lever to verify ow as in
the following warnings, excerpted from a relief valve manu-
facturer’s warning label. Before operating any relief valve,
ensure that it is piped with its discharge in a safe area to avoid
severe scald potential. Read page9 before proceeding further.
Safety relief valves should be reinspected AT LEAST
ONCE EVERY THREE YEARS, by a licensed
plumbing contractor or authorized inspection
agency, to ensure that the product has not been af-
fected by corrosive water conditions and to ensure
that the valve and discharge line have not been
altered or tampered with illegally. Certain naturally
occurring conditions may corrode the valve or its
components over time, rendering the valve inopera-
tive. Such conditions are not detectable unless the
valve and its components are physically removed and
inspected. is inspection must only be conducted
by a plumbing contractor or authorized inspection
agency — not by the owner. Failure to reinspect the
boiler relief valve as directed could result in unsafe
pressure buildup, which can result in severe personal
injury, death or substantial property damage.
Following installation, the valve lever must be op-
erated AT LEAST ONCE A YEAR to ensure that
waterways are clear. Certain naturally occurring
mineral deposits may adhere to the valve, rendering
it inoperative. When manually operating the lever,
water will discharge and precautions must be taken
to avoid contact with hot water and to avoid water
damage. Before operating lever, check to see that a
discharge line is connected to this valve directing
the ow of hot water from the valve to a proper
place of disposal. Otherwise severe personal injury
may result. If no water ows, valve is inoperative.
Shut down boiler until a new relief valve has been
installed.
2. Aer following the above warning directions, if the relief
valve weeps or will not seat properly, replace the relief valve.
Ensure that the reason for relief valve weeping is the valve and
not over-pressurization of the system due to expansion tank
waterlogging or under-sizing.
1. Review the User’s Information Manual with the
owner.
2. Emphasize the need to perform the maintenance
schedule specified in the User’s Information
Manual (and in this manual as well).
3. Remind the owner of the need to call a licensed
contractor should the boiler or system exhibit
any unusual behavior.
4. Remind the owner to follow the proper shutdown
procedure and to schedule an annual startup at
the beginning of the next heating season.
