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 cur-
rent switched on?
- Are the thermostats correctly set?
- Are pressostats, overheating pro-
tection 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 opera-
tion?
- Is there a supply of fresh air to the
installation?
If integral components are of a diffe-
rent make from what is stated in this
manual, see the enclosed loose-leaf.
