(b) “Maintenance” is confined to the specific premise and means preserving or repairing anything that exists and can be maintained by persons regularly employed within a specific building or complex.

(d) “Installation or new construction” means the modification, altering, or installation of any piping/refrigeration or air distribution systems or their components (i.e., boilers, pumps, compressors, circulators, fans, and coils). This work requires state licensed pipefitter/refrigeration workers or sheet metal workers and city and town or state mechanical permits. If boiler installation is over two hundred thousand (200,000) BTU’s on commercial work, a state boiler permit from occupational safety is required.
