ALL FROST DAMAGE IS OUTSIDE OF THE WARRANTY.
Boiler Overheat Protection
The boiler controls will shut down the boiler in the event of overheating. Should this occur, a fault code
will be displayed. Refer to fault codes.
Should this occur a fault code will be displayed. Refer to fault codes.
Loss of system water pressure
The pressure gauge in the diagram below indicates the central heating system pressure. If the pressure
is seen to fall below the original installation pressure of 1.5 bar over a period of time then there could be
a system leak. In this event re-pressurise the boiler using the filling loop supplied. This is a flexible
detachable pipe that connects the cold water supply to the central heating circuit via two taps directly
beneath the boiler. When the pipe is connected open both taps until the pressure on the gauge reaches
1.5 bar, then close both taps and remove the pipe. The source of the leak must be located and resolved
as repeated use of the filling loop will cause damage to the boiler and the system. If unable to do so or
if the pressure continues to drop a qualified and competent Gas Installer should be consulted.
LOW SYSTEM PRESSURE IS INDICATED BY FAULT CODE “F1” - THE BOILER WILL NOT
OPERATE IF THE PRESSURE HAS REDUCED TO LESS THAN 0.3 BAR.
The boiler produces a clear liquid called condensate which leaves the boiler via an internal trap and a drain marked
“J” on the boiler controls diagram. This appliance is fitted with a siphonic condensate trap system that
reduces the risk of the condensate freezing. However should the condensate pipe to this appliance
freeze it will need to be defrosted.
If you do not feel competent to carry out the defrosting instructions below please call a qualified and
competent Gas Installer for assistance.
If you do feel competent to carry out the following instructions please do so with care when handling hot
If this appliance develops a blockage in the condensate pipe, the condensate will build up to a point
where it will make a gurgling noise prior to the boiler stopping and an “L2” fault code being displayed.
To unblock a frozen condensate pipe;
1. Follow the routing of the plastic pipe from its exit point (”J” on the boiler control diagram) through its
route to its termination point. Locate the frozen blockage. It is likely that the pipe is frozen at the most
exposed point external to the caravan holiday home or where there is some obstruction to flow. This
