CONDENSATE DISPOSAL
The condensing unit generates condensate continuously at a rate of up to 5 litres per hour
as a by-product of highly efficient gas burner system. This condensate must be drained via a
pipe to a suitable point of discharge. Because the condensate is a by-product of a gas com-
bustion it is mildly acid. For this reason copper tube and fittings MUST NOT be used as it will
corrode. Instead, Rinnai recommend plastic pipes and fittings such as Unplasticised Polyvi-
nyl Chloride (UPVC) or Polyethylene (PE) which is commonly used for irrigation piping.
