Optimax 25 SCondensate dischargeWhere possible the condensate should discharge into an internal soil pipe or waste system. The minimumpipe diameter required is 22 mm, a trap has already been fitted to the appliance with a flexible tail tofacilitate the connection to the condensate discharge pipe.The pipe should be a solvent weld plastic, not copper, as the condensate has a ph value of 4 (slightlyacidic).Where it is not possible to terminate internally, the condensate discharge pipe may be run outside (seebelow drawing).Any external run is subjet to freezing, in severe weather conditions. To avoid this the pipework shouldbe installed to dispose of the condensate quickly, with as much as possible run internally, before passingthrough the wall.Pipework external to the building should be increased in diameter to 32 or 40 mm solvent weld. It shouldbe run to a external drain or soakaway, with a maximum lenth of 3 metres.If a soakaway (condensate absorption point) is used, it should be constructed as shown below.InternalExternal32/40mm Solvent pipeworkCement motar seal25mm2,5° minimun FallGround level (either/Or)100mm Dia tube-300mmLime stone chippingsHole depth 400mmBottom sealed2 rows of 3 holes10mm diameterfig. 15Note: or use a purpose made type Soakaway for example Mc Alpine SOAK1GR.22
