The probe end cap carries a removable flexible conduit fitting to enable probe replacement without
wiring. The 2 hexagonal caps visible on the probe rear face are there to cover the calibration gas port
and the sample gas port. The latter is merely a tube which passes directly into the flue to enable gas
samples to be drawn or flue temperatures to be taken using other instrumentation. Both ports must
be kept sealed during normal operation for safety and accurate performance.
