2 - INSTALLATION
THE BLOW OFF VALVES
Where the boiler blow off valves are to be fitted, adhere
to the following:
1. Ensure pipes and connections are clean and free
of any foreign material.
2. Pipe blow off pipes to a blowdown tank of
approved design.
3. Ensure that for each blow off line there is a slow-
opening and a fast-opening valve.
4. Ensure compliance with all applicable codes.
STEAM SAFETY VALVE
Adhere to the following:
1. Use only the safety valve provided with the boiler
as noted on the ASME data report.
2. Ensure pipes and connections are clean and free
of any foreign material.
3. Do not install using a pipe wrench. Use the
appropriately sized wrench on the bonnet nut.
4. Install the valve vertically with no unnecessary
intervening piping between the boiler and the
valve.
! WARNING
Under no circumstances should there be any shut off
valve or restriction smaller than the safety valve inlet
between the boiler and the safety valve.
5. Do not cap or plug the weep hole on the side of
the safety valve.
6. Ensure that the valve is vented to a safe location.
7. A discharge pipe shall be of a pipe size equal to,
or greater than, the outlet of the safety valve.
8. Consult local codes for combined safety valve
pipe sizing.
9. Minimize discharge piping fittings and overall
piping run to avoid over pressurization of the
piping, limiting safety valve discharge volume.
10. Do not support discharge piping with the safety
valve. Discharge piping must be supported
2-26
VSRT_IOM_2018-1213
adequately by appropriate means.
11. Fulton recommends the use of a drip pan elbow,
as this provides the needed drainage and
isolation from expansion as required.
12. Terminate the discharge pipe directly to
atmosphere. Discharge pipe must not contain a
shut off valve of any sort.
STEAM PRESSURE GAUGE ASSEMBLY
Adhere to the following:
1. Ensure pipes and connections are clean and free
of any foreign material.
2. Do not install using a pipe wrench. Use the
appropriately sized wrench on the connection
fitting.
3. Install using a siphon loop flooded with water to
act as a water seal to buffer the gauge element.
4. Face the gauge in a direction easily viewable by
the operator.
5. Range the gauge to no more than double the
pressure at which the safety relief valve is set but
in no case less than 1.5 times the safety relief
valve set pressure.
THE WATER COLUMN AND WATER GAUGE
GLASS
! WARNING
Improper installation or maintenance of the gauge
glass assembly can cause immediate or delayed
breakage resulting in bodily injury and/or property
damage.
When installing the water column and gauge glass
connections (refer to Figure 14), adhere to the
following:
1. Inspect the water gauge glass to ensure that the
glass is free of cracks or chips. Do not subject the
gauge glass to bending or torsional stresses.
2. Install the piping from the water column and
gauge glass to a safe blow off vessel of approved
design.
