6.5 CONDENSatE SOaKaWaY
To keep external pipework to a minimum, locate the soakaway
as close as possible to the boiler but ensure it is at least 500 mm
from building foundations and away from other services, e.g. gas,
electricity, etc.
The condensate pipe may be run above or below ground level
and can enter either the top or side of the soakaway tube. Refer
to Figure 6-1.
Ensure that the drainage holes in the soakaway tube face away
from the building.
Backfill both the soakaway tube, and the hole around it, with 10
mm limestone chippings.
Only use a soakaway where the soil is porous and drains easily.
Do not use in clay soils or where the soil is poorly drained.
! CaUtiON !
any damage due to condensate backing up into the boiler
due to a high water table, in the case of a soakaway, or
flooded drains when the condensate disposal is via a
gulley or soil stack, is not covered by the Grant product
guarantee.
6.6 CONDENSatE tRap
Grant Vortex boilers are supplied with a condensate trap to
provide the required 75 mm water seal in the condensate
discharge pipe from the boiler.
The condensate trap for the Boiler House models is supplied
loose in the burner box and needs to be fitted as shown in Figure
6-2.
This 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 6-2.
A flexible hose connects the outlet of the condensing heat
exchanger to the trap inlet. Ensure the elbow connector on the
hose is fully pushed onto the ‘top hat’ inlet connector of the trap.
If connecting the condensate discharge (either internally or
externally) into a waste system or soil stack - the sealing cap must
be fitted in the trap outlet.
On external discharge systems to a hopper, gully or soakaway,
the sealing cap should be removed from the trap outlet.
If there is any discharge of condensate from the overflow outlet,
this could indicate a blockage (possibly due to freezing). Turn off
the boiler and investigate the cause. If necessary contact your
service engineer for assistance.
Care should be taken when siting the trap such that the overflow
outlet is readily visible and that any condensate overflowing from
the outlet cannot cause either a hazard to persons or damage to
surrounding property or equipment.
The condensate trap outlet is at an angle of 48° below the
horizontal. This is to automatically give a 3° fall on any ‘horizontal’
runs of condensate disposal pipe. Refer to Figure 6-2.
6.7 CONDENSatE DiSpOSaL
pipEWORK
The outlet of the trap will accept 21.5 mm to 23 mm OD
Polypropylene overflow pipe for the condensate discharge pipe.
! 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. Remove trap from bracket.
5.
Remove float from trap – clean if necessary.
6. Inspect inside of trap and clean as necessary.
7.
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.
