Siemens Combustion AGG5.210 Transformer 323269-701 316 stainless steel or Teflon-sheathed

316 stainless steel or Teflon-sheathed probes (Series 3R2C5) should be utilized to prevent material degradation

You will need a 13/16" (21mm) socket wrench for the cartridge and a 1/2" (13mm) wrench for the four hex-head bolts securing the strainer housing

The direct-mount design eliminates the need for complex linkages

an open-circuit test should typically show between 25mV and 30mV

Siemens Combustion AGG5.210 Transformer 323269-701 316 stainless steel or Teflon-sheathedThe Siemens AGG5. 210 Transformer is a high specification mains transformer engineered specifically for the Siemens LMV5 burner management system. As a critical component in linkageless fuel air ratio control, this 103 VA unit converts a 120V primary input to multiple 12V secondary outputs, providing stable power to the LMV5 base unit, SQM4 actuators, and AZL52 displays. Unlike standard step down transformers, the AGG5. 210 features secondary circuits
