CONNECTING A 4085-ERA CABLE TO -ERA IGNITER
— CAUTION; Always disconnect the power supply before handling ignition cables to prevent possible electrical shock.
— 4085-ERA cables ship with a plastic protective plug which covers the insulator. It must be removed before attaching to the igniter (unscrew CCW). — At the end of the insulator is a metal tip that makes contact with the electrode pad inside the igniter. Insert the ceramic insulator straight into the spark plug interior and avoid putting any side stress on the insulator which could damage it. — The ceramic insulator and the metal tip are spring loaded to ensure a good contact. It may be necessarily to push the insulator (straight) into the plug until the cable nut can engage the thread on the igniter.
— Tighten the cable nut to the igniter thread, do not over tighten.
— Avoid putting stress on the cable or the igniter.
4085 CABLE TIPS:
— Do not run UV or flame rod detector signal wire in conduit with ignition wires or 120/220 V lines. Flame rod and ignition wiring must be kept separated to avoid ignition flashover and false flame sensing.
— ERA style igniters do not have a ¼“ Ø spark plug terminal, so a 4085-ERA aircraft style cable must be used with them (see page 6)
— Stock a few spare cables and igniters in case they get damaged to help minimize down time.
— See bulletin 4065/4066 for information on North American ignition transformers. Ignition trans- formers are used to create the high voltages required to generate a spark in industrial igniters. When ordering a 4085 cable it’s important to chose the transformer secondary connection (input) plug style based on the transformer connection type. — See bulletin 4055 for information on North American direct spark igniters used to light gas burners. They are generally less expensive to install and require less maintenance than premix pilots. Note that direct spark igniters are not suitable for lighting all burners. Some types of burners require a pilot for safe and reliable lighting. Consult the burner documentation to determine the best way to light a specific burner model.
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
