LOSS OF SYSTEM WATER PRESSURE
The pressure gauge indicates the central heating system pressure. If the pressure is seen to fall below the
original installation pressure of 1-2 bar over a period of time then a water leak may be indicated. In this event
conduct the re-pressurising procedure. If unable to do so or if the pressure continues to drop a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.
6.6.1
HOW TO RE-PRESSURISE
The boiler will not operate if the pressure has reduced to less than 0.3 Bar under this condition.
1. Ensure filling loop isolation valves are closed.
2. Remove the two caps
3. Attach on the filling loop.
4. Turn the filling loop isolation valves to the open position. The system will now fill.
5. Wait for pressure gauge dial to reach 1 to 1.5 bar.
6. Close the filling loop isolation valves.
7. Disconnect the filling loop at left hand side and angle upwards.
8. Attach the two blanking caps.
6.7
CONDENSATE DRAIN
The condensate drain must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing, can cause automatic shutdown of the
boiler.
If freezing is suspected and the pipe run is accessible an attempt may be made to free the obstruction by
pouring hot water over the exposed pipe and clearing any blockage from the end of the pipe. If this fails to
remedy the problem the assistance of a Gas Safe Registered Engineer or in IE a Registered Gas Installer
(RGII) should be sought.
