Adapters do not include detectors--order separately. Use C7035A UV only with 8837-F or -G Adapter because of ambient temperature considerations. Adapter includes Honeywell Heat Block. Or Series R. Also, R can be used in place of any A or B. When flame supervision is mounted, Sensitrol TM Oil Valve cannot be close-coupled because of interference with handle. See Sheet 4343-3 for TwinBed ® II flame detector assemblies. Requires modified version of adapter shown in Fig 1, page 3. Use adapter 4-6153-1
