The external run should be kept as short as possible taking the most direct and most vertical route possible to the discharge point with no horizontal sections in which condensate might collect Do not exceed 3 metres outside the dwelling The external pipe should be insulated using suitable waterproof and weatherproof insulation Class O pipe insulation is suitable for this purpose The use of fittings elbows etc should be kept to a minimum and any internal burrs on cut pipework should be removed so that the internal pipe section is as smooth as possible The customer householder should be advised that even with the above measures this type of installation could freeze and that if this were to occur then boiler shutdown could result requiring remedial action possibly involving a chargeable engineer call out Where there are likely to be extremes of temperature or wind chill the use of a proprietary trace heating system for external condensate drainage pipework incorporating an external frost thermostat should therefore be considered If such a system is used then the installation instructions of the trace heating manufacturer and any specific recommendations regarding pipe diameter insulation etc should be followed All other relevant guidance on condensate drainage pipe installation should also be followed Other cold weather protection methods approved or endorsed by boiler manufacturers and or service organisa
