Pipeline Condensate Disposal
NOTE
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.
Backfi ll 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 fl ooded 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 boilerhouse combi 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 is factory fi tted inside the boiler casing -
mounted on the inside of the left hand side panel - in an accessible
position to allow for routine maintenance.
NOTE
If required, this condensate trap may be re-
located outside the boiler casing. Refer to the
procedure given in Section 6.9. This procedure
must be carried out before the boiler is
installed.
6.7 DISPOSAL OF CONDENSATES
The outlet of the siphon requires a polypropylene pipe with an
outside diameter of 21.5 to 23mm for the condensate drain pipe.
Possible routes for the evacuation pipes.
The boiler casing has several 35mm diameter openings on the sides
and on its base. These are designed to allow the passage of piping,
depending on the installation. These openings can be used to allow
the condensate drain pipe to exit the housing in one of the following
ways:
Side outlet -
The lower openings on each side of the casing can allow the
installation of the condensate drain pipe as follows:
• Connection to the sewer inside the building by passing through
the wall of the house.
• Connection to the sewer outside next to the boiler
• Discharge into an adjacent drain or ditch
• Discharge to a sump with drainage pipe passing above or
below ground level.
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 fl exible 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 fl oat from trap – clean if necessary.
7. Inspect inside of trap and clean as necessary.
8. Check the condition of the fl exible condensate hose between
the trap and the boiler.
9. Re-assemble trap, re-fi t to boiler and re-connect fl exible hose.
Ensure that hose is fully pushed onto the trap inlet connector.
