WARNING
Failure to observe this warning will result in serious injury.
Before fitting the probe, ensure that the boiler is off and the
flue is cool enough to touch.
If hot process gases are flowing through the flue when the
probe intake tube is inserted, it will direct those gases
toward the operator.
Notes
• This procedure is for AZ10 probes mounted to customer-
supplied/installed flanges – see page 11 for threaded
NPT/BSP installations.
• The gasket joints must be gas tight otherwise errors in the
O2 readings will occur.
Referring to Figure 10:
