Condensate Drain
This appliance is fitted with a siphonic condensate trap
system that reduces the risk of the appliance condensate
from freezing. However should the condensate pipe to this
appliance freeze, please follow these instructions:
a. If you do not feel competent to carry out the defrosting
instructions below please call your local Gas Safe
Registered installer for assistance.
b. If you do feel competent to carry out the following instructions
please do so with care when handling hot utensils. Do not
attempt to thaw pipework above ground level.
If this appliance develops a blockage in its condensate pipe,
its condensate will build up to a point where it will make a
gurgling noise prior to locking out an “L2” fault code. If the
appliance is reset it will make a gurgling noise prior to it
locking out on a failed ignition “L2” code.
To unblock a frozen condensate pipe;
1. Follow the routing of the plastic pipe from its exit point on
the appliance, 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 building
or where there is some obstruction to flow. This could be
at the open end of the pipe, at a bend or elbow, or where
there is a dip in the pipe in which condensate can collect.
The location of the blockage should be identified as
closely as possible before taking further action.
2. Apply a hot water bottle, microwaveable heat pack or a
warm damp cloth to the frozen blockage area. Several
applications may have to be made before it fully defrosts.
Warm water can also be poured onto the pipe from a
watering can or similar. DO NOT use boiling water.
3. Caution when using warm water as this may freeze and
cause other localised hazards.
4. Once the blockage is removed and the condensate can
flow freely, reset the appliance. (Refer to “To Light the
boiler”)
5. If the appliance fails to ignite, call your Gas Safe
Registered engineer.
preventative solutions
During cold weather, set the boiler stat to maximum, (Must
return to original setting once cold spell is over)
Place the heating on continuous and turn the room stat down
to 15ºC overnight or when unoccupied. (Return to normal
after cold spell).
Escape of gas
Should a gas leak or fault be suspected contact the National
Gas Emergency Service without delay.
Telephone 0800 111
999
Do nOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp
cloth and finish off with a dry cloth.
do noT use abrasive cleaning materials.
maintenance
The appliance should be serviced at least once a year by
a Gas Safe Registered Engineer or in IE a Registered Gas
Installer (RGII).
Loss of system water pressure
The gauge (G) 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
as shown below. 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.
THE BOILER WILL nOT OPERATE If THE PRESSURE HAS
REDUCED TO LESS THAn 0.3 BAR UnDER THIS COnDITIOn.
To re-pressurise:
1.
Ensure filling loop isolation valves are closed.
2.
Remove the left hand 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 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.
Replace caps.
