3.4.4 Installation Safety Guidelines
The notes and mechanical executions implicit in the following diagrams in sections 3.4.5
to 3.4.8 for capacitance probe installation should be used for guidance purposes only.
Local, state and national codes must be adhered to in all cases. It is important to use
only qualified and experience installation personnel who have been factory trained.
Under all codes that Autoflame are aware of, it is not permitted install only two
capacitance probes without an additional water level detection method. When the
capacitance probes are installed on a boiler application in this way, the boiler must be
protected with a separate auxiliary low water cut-off device.
**WARNING**
ANY PERSON WORKING ON A BOILER MUST BE ADEQUATELY TRAINED AND
HAVE A THOROUGH APPRECIATION OF THE BOILER PLANT. IT IS THE
RESPONSIBILITY OF THE FACTORY TRAINED TECHNICIAN TO ENSURE THAT THE
SYSTEM OPERATION MEETS LOCAL CODES AND REGULATIONS.
For fire tube steam boilers, a sight gauge glass must be installed to visually indicate the level of the
water in the boiler. The water in the sight gauge glass is cooler than the water the in the boiler, and
does not contain bubbles or current effects.
Note: When carrying out a boiler service, the capacitance probes must be cleaned and checked for
correct and safe operation. Care must be taken to ensure that the PTFE coating on the surface of the
probes is not damaged. After cleaning the probes, the water levels commissioned for those probes
must be checked.
The capacitance probes are used to commission the high, control point, 1
st
low, 2
nd
low and end of
probe levels.
