4. 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 displaying "Ignition Lockout" on the
display. If the appliance is restarted it will make a gurgling noise
prior to it locking out displaying "Ignition Lockout" on the display..
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, restart the appliance. (Refer to "To Start the boiler")
5.
If the appliance fails to ignite, call your Gas Safe Registered
engineer.
Preventative Solutions
