C7007A, C7008A, C7009A Flame
Rod Holder & Flame Rod
Assemblies
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.
