To Re-Pressurise the System  
1. Look at the boiler from underneath. There will be two taps  
connected to the cold inlet tap and central heating return tap.  
Do not operate these taps yet !

2. Your installer will have left a short copper pipe with wing  
nuts (the ‘filling loop’) with you for safe keeping.  
3. To re-pressurise this loop MUST be connected to the taps.  
Remove the blanking caps and set aside.  
4. Ensure that the two seals are fitted, and connect the loop to  
the taps with the wing nuts. These should be hand tightened.  
5. Carefully open both taps and check the boiler pressure  
gauge. Once the needle on the gauge is above the 0.5 mark  
both taps can be closed.  
Caps removed  
6. Undo the two wing nuts, remove the loop and refit the  
blanking caps. Put the loop in a safe place for future use, and  
ensure that the seals remain in place

8. Flammable materials must not be stored in close  
proximity to your boiler.  
9. Avoid skin contact when your boiler is in operation, as  
some surfaces may get hot e.g. pipework.  
10. Ensure that the flue terminal, outside the house,  
does not become damaged or obstructed, particularly  
by foliage.  
11. It is important that the condensate drain system is  
not blocked, modified or damaged in any way as this  
would affect the operation of your boiler. Your installer  
should have insulated any exposed pipework.

5.0 Care of the Boiler  
5.1  
Cleaning the Outer case  
The painted panels should be wiped with a damp cloth and  
then dried completely. DO NOT USE ABRASIVE  
CLEANING AGENTS.  
5.2  
Protection & Precaution  
1. The boiler incorporates an integral frost protection feature  
that will operate in both modes. If the boiler temperature falls  
below 5° C, then the boiler will operate until the water  
temperature has been raised.  
2. If a system frost thermostat has been fitted (your installer  
will be able to advise you), then to operate correctly and  
protect your system, the gas and electricity must be left on and  
the appliance set in the central heating mode.  
3. The boiler incorporates an integral pump protection feature  
which continually monitors the time since the pump last  
operated. To prevent seizure, the pump will operate for  
approximately 1 minute if it has not run in the last 24 hours.  
5.3

5. E119 is displayed when the primary water pressure is less  
than 0.5 bar. After repressurising the system the boiler should
