WARNING
Failure to properly pipe boiler may result in improper operation and damage to boiler or structure.
DO NOT increase steam boiler input above the ratings.
DO NOT use softened water in steam boilers. Accelerated boiler corrosion will result. Tie in fresh water
supply to the boiler upstream of a water softener.

contraction noises if not accounted for in the piping system design and installation,
2) high heat transfer rate (heat loss) of uninsulated copper piping must be included in the normal
piping and pickup factors used to size the boiler,

surging, an unsteady water line and wet steam if not thoroughly removed during the boil out
procedure and,
4) galvanic corrosion of the adjoining metal may occur due to dissimilar metals in certain water
chemistries if dielectric unions are not used.
