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 main-
tenance of the installation and what to do should any troubles occur.
- Inspection and service must be carried out by authorized
personnel.
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 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 sheet.
