6.9 EXTERNAL CONDENSATE TRAP
FITTING
The top of the siphon must be installed below
the condensate outlet of the boiler.
When connecting a plastic drain hose, make
sure that the hose is fully inserted into the
outlet end of the fl exible hose to prevent
possible leakage.
The fl exible hose must keep a slope of 2.5 °
minimum (4%) permanently from the boiler
outlet to the smmet of the siphon.

NOTE
CAUTION
Failure to regularly check and clean the
condensate trap may result in damage to the
boiler and will not be covered by the product
guarantee.
NOTE
This process is carried out before the boiler is
installed.
To re-locate the factory-fi tted trap outside the boiler casing, use the
following procedure:
1. Remove both the top casing panel(s) from the boiler.
2. Unscrew and remove the screws securing the bottom of the
rear panel to the base tray of the boiler casing. This must be
done before fi tting of the boiler as the screws are in-accessible
otherwise.
3. Grip the top of the rear panel and pull it upwards. Slide it all
the way up and out of the channels on the rear edge of the
two casing side panels to remove it from the boiler. Refer to
Figure 6-3.
4. Push out pre-cut ‘knock-out’ from condensate outlet hole in
rear of left side casing panel.
5. Disconnect condensate discharge hose from heat exchanger
and condensate trap and remove it from the boiler.
6. Replace with condensate trap hose (Grant product code:
ZCONHOSE2646).
7. Pass the straight connector end of the hose through the new
hole in the left hand casing panel. Push the straight connector
fi rmly onto the condensate outlet connection of the condensing
heat exchanger as far as possible.
8. Refi t the rear casing panel. Ensure that both edges of the rear
panel are correctly located into the channels in the rear edge
of both side casing panels. Then carefully slide the rear panel
fully down until the top edges is level with the top edges of the
side panels.
9. Secure the bottom of the rear panel to the base tray with the
screws previously removed.
10. Remove the trap from the mounting bracket.
11. Unscrew and remove the trap mounting bracket from the left
side panel.
12. Fix the trap mounting bracket to the wall adjacent to the boiler
in the required position.
13. Re-fi t the trap to the mounting bracket. The mounting bracket
supplied with the trap must be used - the trap should not be
supported by the condensate pipework only.
14. Connect the fl exible condensate hose to the trap - pushing the
right angle hose connector onto the trap inlet connection
