INTERNAL CONNECTION
Key to diagrams:
1. Condensate dischange from boiler
2. Universal connector
3. Soil and vent stack
4. Minimum 450mm and up to three storeys
5. Visible air break at plug hole
6. Sink or basin with integrated overflow
7. 75mm sink waste trap
8. Condensate pump
CONDENSATE PIPEWORK:
• Where a new or replacement boiler is being
installed, access to an internal "gravity discharge"
point should be one of the factors considered in
determining boiler location.
• The condensate pipe must be nominally
22mm Ø plastic pipe.
• The condensate pipe work must fall at least 52mm
per metre towards the outlet and should take the
shortest practicable route.
• Ensure there are no blockages in the pipe run.
Internal connections:
• In order to minimise risk of freezing during prolonged
cold spells, the following methods of installing a
condensate drainage pipe should be adopted, in
order of priority.
• Wherever possible, the condensate drainage pipe
should be routed and terminated so that the
condensate drains away from the boiler, under
gravity, to a suitable internal foul water discharge
point such as an internal soil and vent stack.
• A suitable permanent connection to the foul
waste pipe should be used.
• Alternatively if the first option is not possible an
internal kitchen or bathroom waste pipe, washing
machine waste pipe etc. can be used.
Condensate pump:
• Where "gravity discharge" to an internal termination
is not physically possible, or where very long internal
runs would be required to reach a suitable discharge
point, condensate should be removed using a
proprietary condensate pump, of a specification
recommended by the boiler or condensate pump
manufacturer.
• The pump outlet pipe should discharge to a suitable
internal foul water discharge point such as an
internal soil and vent stack, internal kitchen or
bathroom waste pipe, washing machine waste pipe
etc.
• A suitable permanent connection to the foul waste
pipe should be used.
