Thecondensingtanklessgaswaterheaterdischargescondensate.
When heat from the exhaust gas is collected within the secondary heat exchanger, condensation occurs from
moisture in the exhaust gas and the resulting water is discharged from the drain pipe (approx. 2 gallons/hour (7.5 liters/
hour) maximum). It is not a water leak. Do not plug or block the drain line as it must always be allowed to freely ow.
Note : The condensate discharged is acidic with a pH level of approximately 2-3.
A condensate neutralizer may be required by local code prior to disposal.
Thecondensingtanklessgas
water heater tends to show
whitesteam.
After the exhaust gas passes through the
secondary heat exchanger, the low temperature
and high moisture content tends to produce
steam at the vent discharge terminal.
This is a normal occurrence.
During combustion, white
steam may often be seen.
This is normal.
