high-temperature water boilers that have internal continuous water treatment,
under the direct supervision of a graduate chemical engineer, or under the
direct supervision of a person having a minimum of five years supervisory
experience and formal training in the treatment of boiler water.
Accurate records of boiler water chemistry shall be kept and
made available for review by the inspector.

Certificates renewed. They shall also receive an internal inspection every four
years. Accurate records of boiler water chemistry shall be kept and made
available for review by the inspector.
(3) Hot water heating boilers, and hot water
supply boilers shall receive an external inspection annually in order to have
their Certificate renewed. Boilers stamped with the ASME Certification Mark
with the "H" designator shall receive an internal inspection every four (4)
years from the date of manufacturer's completion. Existing units that are not
ASME code symbol stamped but are listed as meeting ANSI Z 21.10.13 standards
shall receive an internal inspection every five years. Units listed as meeting
ANSI Z 21.13 standards shall receive an internal inspection every four
years.
(4) Effective August 30,

Mark with the "HLW" designator shall be inspected externally at least every 24
months while in operation, in order to have their Certificates renewed. Where
construction permits, these units shall receive an internal inspection at the
inspector's discretion but not to exceed every six (6) years from the date of
manufacturer's completion.
(5) All
existing water heaters shall be inspected externally on an annual basis in
order to have their Certificates renewed. Where construction permits, they
shall be inspected internally every five years from the date of manufacturer's
completion. Existing water heaters may be placed on the inspection frequency
