Flame Detector Adapter Dimensions in inches
To order, specify: Adapter number with appropriate letter suffix. Example: 8836-B Adapter NOTES: Adapters with pipe unions are intended to be used with flame rod heads that are wired without quick disconnects. If the flame rod cable has a spark plug style boot, use an adapter without a union. A throttling valve in the cooling air line is suggested for limiting air flow to minimum amount required. "Radius max." applies to adapters not dimensioned above: It is the radius of a cylinder in space the adapter would occupy while being screwed into mounting. 8832 and 8833 adapters are intended for flame rods. See Sheet 8800-2. * Includes a non-conducting adapter (Honeywell Heat Block). # Includes a pipe union for easy access to the detector without twisting or disconnecting wires.
