† Total air is main air plus atomizing air plus 130 scfh for pilot air. ‡ Honeywell Ultravision Flame Detector C7027A and Honeywell Flame Supervision ProtectoRelay RA890G yielded 1.5 micro amps or greater for all above rates. • The electrode setup used was that shown in drawing B4-7249. The cooling air was shut off for ignition and turned back on aerwards.
