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 posi-
tion 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 opera-
tion?
–
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.
