EN1C-0015SZ20 R0314 6 INSTALLATION AND OPERATION PLANNING THE INSTALLATION Proper flame detector application is the back of a safe and reliable flame safeguard installation. Refer to the burner manufacturer’s instructions as well to those included here. Follow all instructions carefully. CAUTION 1. Do not connect these detectors to non-Hon- eywell manufactured controls (primaries, pro- grammers, multiburner systems, and burner management systems). Unsafe conditions could result. 2....

7 EN1C-0015SZ20 R0314 IMPORTANT When installing the detector, make sure it does not respond to ignition spark. Single burner requirements The detector must have an unobstructed view of the flame it is supervising under all firing conditions. This implies a proper sighting angle and the minimization of screening effects. Sighting angle The first 30 percent of a flame (the root) radiates the most intense ultraviolet energy. The low angle sighting permits the...

EN1C-0015SZ20 R0314 8 INSTALLATION CAUTION 1. lnstaller must be a trained, experienced flame safeguard control serviceman. 2. Disconnect power supply before beginning installation to prevent electrical shock and equipment damage. 3. All wiring must comply with applicable local electrical codes, ordinances and regulations. 4. Voltage and frequency of power supply con- nected to this detector must agree with the values marked on the detector. 6. On multiburner...

9 EN1C-0015SZ20 R0314 IMPORTANT The notch and arrow on the faceplate must be aligned in a vertical plane with the notch up and the arrow pointing down. The housing must be mounted with the conduit opening approximately 45° below horizontal (see Fig. 7) To mount a C7061A (Fig. 8): A The mounting flange is in two pieces. Loosen (but do not remove) the three screws holding the flange together. B Slightly rotate the detector so the slots in the back sec- tion of the mounting...

EN1C-0015SZ20 R031410 WIRING CAUTION When using a C7061A/F with an R7061 or R7861 Dynamic Self-Check amplifier, be careful not to short the white shutter lead wires together (by wiring incorrectly, leaving an incorrect jumper wire, or stripping the insulation too muc h so the bare lead wires can touch). If the shutter leadwires are shorted during the operation, the amplifier can be permanently damaged and nonoperative. 1. All wiring must comply with applicable...
