CONDENSATE DRAIN CONNECTIONS
The condensate pipe can be fitted after the boiler is positioned
and terminates from the base of the boiler casings.
Where possible, connect the condensate pipework to an
external waste drain.
If the boiler is to be fitted in a position where the external
ground level is higher than the boiler, and there are no internal
drains, a condensate pump can be fitted (refer to
manufacturers' instructions).
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, fill
the trap via the fill point on the condensate unit, pouring a
small amount of water within, until retained within the 'U'
section.
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.
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.
