External condensate pipework

All Worcester condensing boilers have within the appliance a syphonic condensate trap. Rather than the condensate constantly dripping into the discharge pipe, the condensate is collected into a trap which releases it in 100ml quantities. This will help prevent freezing occurring.

The redesigned syphon for the Greenstar i Junior and Greenstar Si models has an easy slide-on push-fit connection to the sump secured by a retaining bracket. There is a removable service cap, making insitu maintenance and cleaning quick and easy.

Wherever possible the condensate discharge pipework should be routed and terminated internally. If there is no alternative and the only available route is external, the following conditions should be observed:

• The pipe run should take the shortest practical route
• The pipework should be insulated with weather-resistant insulation
• The pipe should terminate as close as possible to the ground or drain, whilst still allowing the condensate to safely disperse. This would prevent wind blowing up the pipe
• The pipework should be installed with the minimum of horizontal runs and with a continuous fall of 3degrees and be suitable supported
