Fault location, functional troubles

Trouble free operation is depending 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 suficient?
• 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 sheet.
