8. Handing over of the
installation
• Make repeated start attempts to ensure that the adjustments function.
• Close the ball valve during operation to check that the gas switch
switches off at the set value.
• Remove the hose for the air pressure switch to check that the burner
locks out.
• Check that all protective covers and measurement nipples are
mounted and fastened.
• Fill out necessary test reports.
• Instruct the persons in charge of the operation on the service and
maintenance of the installation and what to do should any troubles
occur.
• Inspection and service must be carried out by authorized personnel.
9. Fault location,
functional troubles
Trouble free operation is dependent on three factors: electricity, gas and air
supply. Should there be any changes in the ratio between these three factors
there is a risk of break downs. It has been proved that most break downs
are caused by simple faults. Before calling the service engineer, the following
should therefore be checked:
• Is the gas cock open?
• Are all fuses in order and the current switched on?
• Are the thermostats correctly set?
• Are pressostats, overheating protection etc. in operating position and
not locked-out?
• Is the gas pressure sufficient?
• Is the gas burner control in start position?
• Has the gas control or the motor protector locked out? - Reset.
• Is the circulation pump in operation?
• Is there a supply of fresh air to the installation?
• If integral components are of a different make from what is stated in
this manual, see the enclosed loose-leaf.
