Can someone please tell me how to check uv flame detecters?
I just picked up a commercial account. It's a large Smith oil fired with a Carlin Burner. The Primary is a Honneywell R7795 control. The light sensor is a UV rod.
I went there for a No Heat the conrtol was bad, but I am looking for advise for down the road. never worked with UV before.no paperwork near boiler.
Thanks

    UV detector

    For ultraviolet(Minipeeper flame detector) you need a purple Flame Simulator # 123514B. For the R7795A or C you plug it into the meter jack on the amplifier. These controls have an integral amplifier, some Honeywell controls have an add on amplifier.

    The system may use a C7027, C7035 0r C7044 Minipeeper Ultravioloet Flame Detector. The Flame signal amplifier is a R7249A (purple) minimum acceptable steady flame current is 3 1/2 microamperes maximum is 7 1/2 microamperes.

    The best meter for detecting and troubleshooting these systems is a Honeywell W136A or B meter.

    A good manual to get hold of is Flame Safeguard Controls a Honeywell Textbook Catalog # 71-97558. The information for FSG controls is in the Honeywell Catalog.
