Condensate
Disposal
6.7. Condensate Disposal
Pipework
The boiler is supplied with a flexible
plastic condense disposal pipe, factory-
fitted to the outlet of the trap.
This flexible discharge pipe must be
routed through the boiler to exit via one
of the pre-cut ‘knock-outs’ in the
bottom flange of the boiler back panel -
at the right rear of the bottom casing.
Push out the ‘knock-out’ from the hole
taking care not to distort the back panel
flange.
The outlet end of this flexible pipe will
accept 21.5mm OD to 23mm OD
Polypropylene overflow pipe for
connection of the condensate discharge
pipe below the boiler.
When connecting plastic discharge
pipe, ensure that the pipe is fully
pushed into the outlet end connector
on the flexible pipe to prevent the
possibility of leakage.
6.6. Condensate Trap
Grant Vortex Eco Wall-hung boilers are
supplied with a factory-fitted
condensate trap to provide the required
75mm water seal in the condensate
discharge pipe from the boiler.
T
his trap incorporates a float (which will
create a seal when the trap is empty) and
an overflow warning outlet (fitted with a
plastic sealing cap), See Figure 6-3.
The trap is factory-fitted inside the boiler
casing – mounted on the outlet of the
condensing heat exchanger - in an
accessible position to allow for routine
maintenance.
A ‘push-fit’ elbow connects the outlet of
the condensing heat exchanger to the
trap inlet. Ensure the elbow is fully
pushed onto the ‘top hat’ inlet
connector of the trap.
With the trap fitted inside the boiler
casing, the sealing cap must be fitted.

The bottom bowl is sealed to the trap
body and cannot be removed.
To inspect and clean the trap
1. Remove expansion vessel (system
models only) and hang on front of
boiler casing.
2. Disconnect and remove snorkel
tube to gain access to trap.
3. Leave inlet connector fitted to
connecting elbow.
4. Unscrew the inlet connection nut.
5. Separate trap from the ‘top hat’ inlet
connector and nut.
6. Unscrew outlet connection nut,
disconnect disposal pipe from trap.
7. Remove trap from boiler.
8. Remove float from trap – clean if
necessary.
9. Inspect inside of trap and clean as
necessary.
10. Re-assemble trap, re-fit to boiler
and re-connect inlet connection.
Ensure that elbow is fully pushed
onto the ‘top hat’ inlet connector
and disposal pipe is correctly
connected to trap outlet.
6.8 Inspection and Cleaning
of Trap
The trap must be checked at regular
intervals (e.g. on every annual service)
and cleaned as necessary to ensure
that it is clear and able to operate.

NOTE
Failure to regularly check and clean
the condensate trap may result in
damage to the boiler and will not be
covered by the Product Warranty.
