LIGHTING THE PILOT
Themanifoldunitsareequippedwithstandingpilotsandeachshouldbelitimmediatelyafterthegasis
suppliedtotheequipment.
1. Beforeattemptingtolightthepilots,turnoffthemaingasvalvetotheequipmentandwait5minutesto
clearthegas.
2. Turnoffallgascontrolknobs.
3. Turnoncontrolvalveandlightallpilots.
