3. Ensure all labels on the boiler will be fully visible for
maintenance and inspection.
Install Boiler Trim
Each Reliance boiler is supplied with a safety relief valve
sized in accordance with ASME requirements. Adhere to the
following installation requirements:
1. The safety relief valve (Figure 2) must:
» Be connected to the coupling located in the
top rear outlet section of the boiler.
» Be installed in the vertical position.
» Be installed with a 4 inch (101.6 mm) nipple
between the boiler and the safety valve.
NOTE: Safety relief valve size is determined by trim pressure
and is supplied in the trim kit along with appropriate bushing,
inlet and outlet sizes.
The discharge pipe must:
» Not have a diameter less than the full area of the
valve outlet.
» Be as short and straight as possible and so
arranged as to avoid undue stress on the valve.
» Be supported by means other than the safety
valve itself.
» Be piped to avoid danger of scalding personnel.
NOTE: Each boiler is equipped with a pressure-temperature
gauge to be installed in the outlet piping section of the boiler.
