1. Check the general condition of the heating system (visual inspection).
2. Check the heating system function.
3. Check the components in contact with fuel and water throughout the
system for the following:
• Tightness
• visible signs of corrosion
• Signs of ageing
4. Check the combustion chamber and heat emitter for contamination and
clean.
Shut down the heating system for this step.
chapter 9.1, page 34
5. Check and, if required, replace gaskets and packing cords at:
• Burner door
• Inspection aperture of reversing chamber
• Inspection aperture of flue gas collector

10. Check the control unit settings are suitable and adjust if required. See technical documentation for burner.
11. Test all safety equipment (safety shutdown) and record findings. For
example:
▶ High limit safety cut-out
▶ Pressure limiter min./pressure switch min.
▶ Pressure limiter max. (if installed)
▶ Low water indicator (if installed)
▶ Other safety equipment.
12. Conduct a water analysis and record the results in the operator's log:
▶ pH value
▶ Residual hardness
▶ Oxygen binder
▶ Phosphate
▶ Electrical conductivity
▶ Appearance
▶ Check water records (e.g. amount of top-up water) in the operator's
log.
13. Check the neutralising system.
14. Final check of the inspection work, take measurements and record
