1 USER INSTRUCTIONS
This boiler must be serviced annually. Contact Warmflow for further details.
In the event of a breakdown please contact your commissioning engineer who
should contact our service department whilst at your home, to report the fault.
1.1 Dual Thermostat – Non-Combination Boilers
The radiator temperature is regulated via the boiler control thermostat. The
thermostat is user adjustable from nominally 45°C to 80°C. Turn the control knob
(1) clockwise to increase temperature, and anticlockwise to decrease.
The thermostat has a built-in manually reset safety cut off which will ‘lock out’ in
the event of the boiler overheating and which will need to be reset in order to
restore operation.
Remove the lock-out cover (2) using a coin or screwdriver (turning anti-clockwise)
and depress the red button to reset.
Do not press the reset button while the boiler is still hot as this will cause
damage to the thermostat.
1.2 Burner Lockout
When the pressure jet oil fired burner stops after
failing to fire the red reset button (1) will be
illuminated.
This indicates that there is a fault or there is no
fuel getting to the burner.
The house holder should only reset the burner
twice in succession.
If the burner continues to lockout contact
Warmflow or your service engineer.
