Instlltion n Strt-Up Not: Do not instll siwys. Th iphrgm shoul b horizontl. 1. Thoroughly purg inlt piping to rmov irt n bris whih oul mg th rgultor or impir its oprtion. If this nnot b on, filtr or strinr shoul b instll h of th rgultor (s Snsus Bulltin RDS-1498, Rgultor Prssur Rtings). Mk rtin tht rgultor is fr of ny irt or forign mttr tht might hv ollt. 2.

(S Figur 1 on pg 2.) This ontrol piping shoul not b lss thn ¼" in siz n shoul b qutly prott ginst brkg (Rgultors will go wi opn if th ontrol lin is brokn). CAUTION It is th usr s rsponsibility to nsur tht ll rgultor vnts n/or vnt lins xhust to non-hzrous lotion wy from ANY POTENTIAL sours of ignition. Whr vnt lins r us, it is th usr s rsponsibility to nsur tht h rgultor is iniviully vnt n tht ommon vnt lins ARE NOT us. Th rgultor will work to livr th prssur, for whih it is just, t tht point in th outlt piping whr th ontrol onntion is lot.
