The condensing tankless gas Water Heater tends to
emit 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.
General Parts
This illustration shows an example of installation.
The exact installation configuration may be slightly different.
Water Heater
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 condensate drain pipe
(approximately 2 gallons/h (7.5 L/h) maximum). It is not a water leak. Do not plug or block the drain line as it
must always be allowed to freely flow.
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.
During combustion, white
steam may often be seen.
This is normal.
