necessary to move the boiler, remove the weight from the isolators by raising the
equipment before moving.
10. Installing Boiler Trim
a) Each boiler is supplied with a safety relief valve sized in accordance with ASME
requirements. The safety relief valve shall be connected to the coupling located in the top
of the boiler (Figure 3a). The safety relief valve must be installed with a 6" nipple (8” for
PHW2000) between the boiler and the safety valve. The safety relief valve must always
be installed in the vertical position. The discharge pipe shall be not less than the full area
of the valve outlet. The discharge pipe shall be as short and straight as possible and so
arranged as to avoid undue stress on the valve.
Caution
The discharge from safety relief valve shall be so arranged that there will be no
danger of scalding personnel. When the safety relief valve discharge is piped away
from the boiler to the point of discharge, there shall be provisions made for
properly draining the piping.
