Manufacturer’s instructions must be followed for the correct connection of the
condensate discharge pipe from the boiler as this may vary due to the design
of the boiler. For example a visible air break and trap is not required if there is a
trap with a minimum condensate seal of 75 mm incorporated into the boiler.
Internal Pipe Run In Unheated Spaces
Condensate discharge pipes that are routed in an unheated space such as a loft
or garage should be insulated to prevent freezing.
Internal condensate discharge pipework must be a minimum of 19mm ID
(typically 22mm OD) plastic pipe or as per manufacturer’s instructions and this
should “fall” a minimum of 45mm per metre away from the boiler, taking the
shortest practicable route to the termination point.
diagrams)
To minimise the risk of freezing during prolonged sub-zero conditions, an
internal “gravity discharge point” such as an internal soil stack (preferred
method), internal kitchen, utility room or bathroom waste pipe e.g. from a sink,
basin, bath or shower should be adopted, where possible.
Note - A suitable permanent connection to the foul waste pipe should be used.
Figures 1, 2(a), 2(b) show appropriate connection methods.
