4055-L EXTENDED LENGTH IGNITERS

WHEN SETSCREWS ARE LOOSENED, ASSEMBLY CAN BE WITH- DRAWN FOR CLEANING, THEN REINSERTED TO OPTIMUM DEPTH.

The 4055-L series igniters are extended length igniters with the same variable length adapters as the 4055-M.

Special engineered versions of the igniters can be also made with: — Custom lengths — The "ERA style" ignition cable connector — Special adapters or igniter tips

They feature: — Wide range of available fixed lengths from 12 (305) to 48 (1219) inches (mm) — Overlapping ceramic electrode insulators — A small enough diameter to fit through a ¾ " pipe fitting — Threaded adapters that allow adjusting the insertion length.

Adapter assemblies include: positioning collar, mounting adapter, o-ring, and setscrews.

Note: All 4-57719-# electrodes are built with modified versions of igniters labeled with "R240-2755" or "I-2". Do not replace the electrode in a 4055-L with an unmodified "R240-2755" or "I-2" electrode. It will not function correctly.
