12. Troubleshooting
Gas Burner
Conditions favourable to disruption-free operation of the system can only be
guaranteed through the interaction between three factors – electricity, gas flow and
combustion air. A change in any of these factors may cause disruptions.
It has been shown that a large proportion of disruptions can be attributed to
relatively small things. Therefore, before requesting servicing, you should ascertain
the following:
1.
Are the system’s gas taps open?
2.
Are the fuses intact and is the power on?
3.
Are control devices (room thermostat, boiler thermostat, etc.) correctly set?
4.
Is gas pressure to the burner sufficient?
5.
Are the burner controls on standby and not locked?
6.
Is air supply to the burner adequate?
