The small size of these devices enable their application to flame detection in installations where space is limited. The holder and flame rod assemblies facilitate flame proving on gas burners or gas-ignited oil burners which are controlled by electronic flame safeguard systems.
• The C7007A, C7008A, and C7009A may be used with flame safeguard controls utilizing the rectification principle of flame detection.
• The C7007A is a small, sturdy holder for a 3/16 inch [4.8 mm] diameter flame rod (flame rod ordered separately).
• The holder is externally threaded (1/2-14 NPT) for pipe mounting.
• A collet chuck and setscrew position a flame rod securely. If additional support of the flame rod is required, the C7007A extension assembly is internally threaded (1/8-27 NPT) to accept a 1/8 inch iron support pipe.
• The C7008A is a miniature flame rod assembly with a threaded (external 1/4-18 NPT) base, snap-on cover, and flame rod. • The C7008A can be used without the cover and a coverless model is available.
• The C7008A is available with several lengths of flame rod. One end of the flame rod is threaded for insertion into the C7008A and the other end may be cut to an exact size.
• The C7009A is a smaller diameter flame rod assembly with an externally threaded (1/8-27 NPT) base and readily accessible Rajah electrical connection.
• The C7009A has a 12 inch (305mm) flame rod which one end is threaded and the other capable of being cut to an exact size. IMPORTANT T
he specifications given in this publication do not include normal manufacturing tolerances. Therefore, this unit may not match the listed specifications exactly.
