CONDENSATE DRAIN
This appliance is tted 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 or in IE a Registered
Gas Installer (RGII).
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 a condensate drain pipe if you cannot reach it
from ground level. Be aware that any water used can quickly
freeze if it falls onto pathways, causing a possible slip hazard.
If this appliance develops a blockage in its condensate
pipe, its condensate will build up to a point where the
burner will go out:
Ignition Lockout
Check other Gas Appliances work
If not, re-instate gas supply
Reset Boiler by pressing r
If fault persists contact installer
If the appliance is reset it will not light prior to it locking out
displaying the above 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 ow. 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 identied 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 ow
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).
