1. Install 12" (300mm) above highest point of downstream piping.
2. Install bonnet side up and allow for accessibility for testing /service.
3. Install where discharge or spillage is not objectionable.
4. Do not undersize supply or oversize the valve in relation to demand.
5.
Protect from freezing.
6. ASSE Standard 1020 requires that the atmospheric vent valve
remains open until the valve body pressure exceeds 1lb. Until this
pressure is reached, some amount of spillage will occur at the at-
mospheric vent. In order to minimize this leakage on startup close
the downstream shutoff valve and open inlet valve quickly.
