INSTALLATION
ƒ
The Blow Off Valves
Where the boiler blo
w 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.
ƒ
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.
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 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.
