CONDENSATE DRAIN CONNECTIONS
The condensate pipe can be run to either the left or the right
side of the boiler and for ease of installation should be fitted
before the boiler is positioned. Remove the boiler back
casing before installing the condensate pipework.
To install the condensate pipe, after deciding the direction in
which it should run, feed the long end through the side
casing from the inside. Attach the short end (with the
connecting nut) to the drain connector on the back of the
condensing unit, ensuring a watertight seal is made.
Where possible, connect the condensate pipework to an
external waste drain.
The drain pipe must be installed to allow the condensate to
drain naturally from the boiler, on a minimum fall of 1:20.
The drain from the boiler must be 22mm diameter pipework.
The pipework from the condensate trap to the external
drain is not supplied with the boiler.
Upon successful installation of the condensate pipework,
remove the inspection cover from the top of the condensing
unit and pour a small amount of water inside. Examine the
condensate pipework for any resultant leaks and rectify
accordingly.
Failure to fill the trap with water before firing the boiler may
result in damage to the drainage pipework and potentially
allow the escape of flue gases. Any damage caused as a
result of not filling the trap will not be covered by the
appliance guarantee.
This process will also leave water inside the ‘U’ section of the
condensate pipework, creating a seal to stop the escape of flue
gases.
Failure to carry out this procedure will result in damage to
the boiler and invalidate the appliance warranty.
IMPORTANT NOTES:
When running any external pipework from the trap to the drain, it
is essential that the pipework is kept to a minimum and is
insulated to prevent the condense from freezing.
MAINTENANCE:
The trap should be inspected at regular intervals to ensure
correct operation, and should be checked as part of the annual
service schedule.
