6.5 Condensate drain pipe

This boiler produces condensate. Condensate must be drained otherwise the boiler

will not function and can cause product or property damage.

The condensation drain pipe should be connected to a drain in the building by means

ofanopenconnection.Bythismeansthepossibilityofdraingasese󰀨ectingtheboiler

isprevented.Thedrainconnectionshouldhaveaminimumdiameterof1.25"/32mm.

Install the condensation drain pipe according to applicable local code.

If the condensate outlet of the boiler is lower than the public sewage system a

condensate pump must be used.

The condensate produced by the boiler has a pH value between 3 and 4.

Install a neutralization unit if required by local code. It is recommended, but not

requiredtoinstallacondensateneutralizer.Rinnaio󰀨ersacondensateneutralizer

designed to work with all boiler models. The condensate neutralizer kit comes with

allthenecessaryttingsandmountingmaterial.PVCpipemustbesuppliedbythe

installation contractor.

Do not drain the condensation water to the external rain gutter because of the

danger of freezing and blockage of the drain.

Before putting the boiler into operation ll the condensate trap with 1.27 cups /

300 ml of water. If the boiler will be installed in a high temperature installation

such as baseboard with a supply temperature of 160°F or above, ll the

condensate trap with mineral oil instead of water.

Use materials approved by the authority having jurisdiction. In absence of such

authority, PVC and CPVC pipe must comply with ASTM D1785, F441 or D2665.

Cement and primer must comply with ASTM D2564 or F493.

Periodic cleaning of the condensate disposal system must be carried out. See

the Rinnai Boiler Application Manual for further information and for a piping

diagram for the condensate.
