Loosen the cover screw Fig. 83 and remove the cover. Insert the 2 leadwires NEC Class 1 through the knockout in the bottom of the case and Connect them Io the screw terminals on the terminal board and to the terminal si rip or wiring sUbbase of the flame safeguard control refer to Table VII and Fig. 85 or 86 . Terminals T1 and T2 on the Q624A must be Connected to the proper terminals of the flame safeguard control as given in Table VII. If the name detector and the ignition transformer are not property connected the detector may sense ignition spark which could cause a haiardous condition.
