BOARD INTERPRETATION
METAL TAG REQUIREMENTS FOR WATER HEATERS
(enacted 12-03-2012)

1.   Introduction

The Board of State Examiners of Plumbers and Gas Fitters (“Board”) has voted to interpret the language of Chapter 142, Section 17 of the Massachusetts General Laws stating:

Water tanks, plainly marked by the manufacturer, by stamping into the metal of the tank, or on a metal plate permanently attached to the tank, in a conspicuous place.

2.   Interpretation

The metal foil tag attach to most water heaters meet these requirements.

3.   Rationale     

      Most manufacturers now affix a foil tag permanently to the outside jacket of their water heaters in lieu of attaching it to the actual vessel itself.
