how do you start or ignite an Ideal Response 120 combi boiler?

I have an ideal response 120 boiler. When their is power to the boiler and the room thermostat is turned up the boiler automatically ignites. Maybe the problem is the room thermostat. Also check that the boiler hasn't lost its power supply ie fused. There is also a reset button on the boiler underneath the boiler in the front right hand corner, if this has popped out try pushing back in. There is also an automatic shut off when the water pressure drops below 0.5 bar. If this has happened you need to top the system back up to 1.0 bar and the boiler should automatically re-ignite.
