4.1 RE-PRESSURING THE HEATING SYSTEM
To re-pressurise the heating system:
1. Remove the bottom panel to gain access to the filling key and filling link.
The fillink link is situated as indicated below:
2. Insert the filling key into the bottom of the charging link and push it upwards. The arrow on the key shaft must be in line with the
open padlock symbol on the charging link.
3. Turn the filling key clockwise to the closed padlock position.
It is important to regularly check the pressure gauge on your combination boiler to keep it running efficiently. The
pressure should be at an optimum level of 1.5 bar. If the pressure falls below 1 bar the boiler may stop working
and require re-pressurising & resetting.
