shall be packed with suitable nonasbestos rope and filled with suitable
compound that will not become soft at a temperature of 40 degrees C 100
degrees F. Boilers and firing equipment shall be supported from the
foundations by structural steel completely independent of all brickwork.
Boiler supports shall permit free expansion and contraction of each portion
of the boiler without placing undue stress on any part of the boiler or
setting. Boiler breeching shall be as indicated with full provision for
expansion and contraction between all interconnected components.
3.2
PIPING INSTALLATION
