POINTS FOR THE BOILER USER
Note. In line with our current warranty policy we would ask that you check through the following guide to identify any
problems external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than
with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained
by the engineer.

The nature of all combination boilers is to heat up water directly from the incoming mains water supply directly through the boiler
to supply domestic hot water at the stated flow rates, (as shown in the boiler installation instructions), to achieve a 35
temperature rise. As the ambient temperature of the cold main varies during the summer and winter months it is likely in the
colder winter months that the flow rate will need to be reduced at the outlet taps to achieve the same temperatures achieved in the
warmer summer months. This is not a fault with the appliance but is relevant to the varying temperature of the incoming cold
mains water supply.

• Check there is power to the boiler – switch (A) in the ON position and ' 0 ' displayed on the
controls.
• If ' 0 ' not displayed then not a boiler fault – contact your installer/service company.
• Press reset button (D) for 2 seconds to repeat ignition sequence.
• Check gas supply (try another appliance – cooker/fire etc.) – If no gas supply then not a boiler
fault – contact gas supplier.
• Check condensate pipe is not blocked or frozen. If blocked clear blockage – if not possible to
check contact your installer.
• Press reset button (D) for 2 seconds, the boiler should then re-light. If fault recurs this
indicates an overheat condition. The boiler should be turned off and your installer contacted.
• Check if ALL radiators have thermostatic radiator valves fitted. If they have contact your
installer.
• Check pressure gauge on boiler shows a minimum of 1 bar. If not re-pressurise via the filling
loop to 1 bar (if unsure contact your installer), turn off the tap on the filling loop and turn the on/
off switch (A) off and then back on again to reset the boiler. If unable to do so or if the pressure
continues to drop after filling then contact your installer.
• Check if ALL radiators have thermostatic radiator valves fitted. If they have contact your
installer.
• Check external programmer is set to an 'ON' period.
• If already set to an 'ON' period then check the programmer by setting to continuous if boiler
then fires – Contact your installer to rectify the programmer.
• Check room thermostat by turning fully up, If '0' is not displayed on the user controls then
contact your installer.
• Check for dripping / dribbling taps or showers – turn fully off.
• Check for leaks from the domestic hot water pipework and if found contact your installer.
• This is a normal function of the boiler to periodically pre heat the plate heat exchanger to
optimise delivery time for domestic hot water to taps or showers.
