Condensate Disposal Pipework; Inspection And Cleaning Of Trap - Grant Vortex Series Installation And Servicing Instructions

6.7 CONDENSATE DISPOSAL
PIPEWORK
The condense trap outlet is at an angle of 48° below the
horizontal. This is to automatically gives a 3° fall on any
'horizontal' runs of condense disposal pipe. Refer to Figure 6-3
and see trap outlet/pipe.
The outlet of the trap will accept 21.5 mm to 23 mm OD
Polypropylene overflow pipe for the condensate discharge pipe.
Possible routes for disposal pipework:
The boiler enclosure has one rectangular opening in each side
and rectangular openings in the base. Refer to Section 2.4 for
dimensioned drawings of the enclosure. These are designed to
allow pipework to pass through, to suit the installation. These
openings can be used to allow the condensate disposal pipe to
exit the casing in one of the following ways:
Side outlet - The opening on either side of the enclosure can
allow the condensate disposal pipe to be installed as follows:
• Connection to an internal stack - passing back through the
wall of the house.
• Connection to an external soil stack adjacent to the boiler.
• Discharge into an adjacent (external) drain or gulley.
• Discharge into a soakaway - with the pipe either above or
below ground level.
Bottom Outlet - There are two openings in the base that can
allow the condensate disposal pipework to be installed as follows:
• Discharge into a drain or gulley beneath the boiler (e.g. a
drain built into the concrete base for the boiler).
• Discharge into a soakaway - with pipe below ground level.
! NOTE !
When connecting plastic discharge pipe, ensure that the
pipe is fully pushed into the outlet end on the flexible hose
to prevent the possibility of leakage.

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.
The bottom bowl can be unscrewed from the trap body for
inspection and cleaning.
To inspect and clean the trap:
1. Disconnect flexible condensate hose from inlet connector.
2. Unscrew the inlet connection nut.
3. Remove the inlet connector and nut from trap.
4. Disconnect the condensate disposal pipe from the trap outlet.
5. Remove trap from bracket.
6. Remove float from trap – clean if necessary.
7. Inspect inside of trap and clean as necessary.
8. Check the condition of the flexible condensate hose between
the trap and the boiler.
9. Re-assemble trap, re-fit to boiler and re-connect flexible
hose. Ensure that hose is fully pushed onto the trap inlet
connector.
! 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.
