Current legislation requires a mandatory annual service of your water heater.
Once a year, have it checked by a qualified professional.
Annual service contract formats may be suggested to you by service providers for all boiler servicing. Contact your gas fitter or
our commercial services.
The manufacturer's warranty, which covers manufacturing faults, should not be confused with servicing operations.
This type B11BS boiler is fitted with a sensor (located in the draught diverter) which shuts off the gas supply if there is a
problem with the evacuation of combustion products.
This device puts the boiler in safety shutdown status, with indicator lights (22) 40 and 80 flashing.
Automatic restart occurs after an interval of approximately 15 minutes.
Important:
if the boiler shuts down repeatedly, the exhaust fault must be corrected by getting a specialist to check that the
chimney is empty because there is probably a total or partial blockage of the combustion products evacuation chimney. Check
that the fresh air flow rate required for combustion is in fact available.
Warning
: this flue gas checking device must not be disconnected or have unwarranted work carried out on it. If it needs to be
replaced, only original parts may be used.
