MAINTENANCE AND SAFETY INSPECTIONS (cont'd)
Periodic Inspection of Operation Components (cont'd)
CAUTION: THE RELIEF VALVE IS A PRIMARY SAFETY DEVICE.
2. The temperature and pressure relief valve
may be checked by slowly lifting the seat
lever on top of the valve to determine its
condition for safe operation. The openings
inside the valve may become restricted by
a buildup of scale and become
inoperative. If the valve does not open
and close properly when tested, it must
be replaced. Replace the relief valve with
like kind or one meeting the requirements
stated on the rating decal located
adjacent to the relief valve.
3. A table of periodic safety inspections is an
attachment of this manual for ease of
reference by the building service
technician or licensed equipment
operator. Since water heater designs
vary, only some of these listed
inspections may be appropriate for your
particular model.
4. PVI strongly recommends the recording of
significant events, such as maintenance
or repair actions and safety inspections,
and encourage the preparation of an
event log for this purpose. All recorded
events should be dated, fully described,
and signed by the individual performing
the service, repair, or inspection. (See
Table 27A-1, page 5 for sample of
Inspection Record.)
