flame discrimination problem

[un421ate1]

Having problems sighting flame scanners on multi-burner boiler (gas/ oil fired)because of discrimination problems.
Does anyone manufacture a flexible? sighting tube that can be adapted to closely supervise burner flame.
Tube would be located in combustion air duct with operating temperature of about 400deg F.
many thanks in advance.

The vendors who have 'discriminating' scanners typically have fiber optic assemblies that mate up to their scanners.

Iris (now Honeywell):

Fireye has a different FO for different scanners. Gotta poke around or call them.
