Overview of Condensing Continuous Flow Gas Water Heater

This water heater is a high efficiency, fully condensing appliance. Unlike a traditional continuous flow

water heater, a condensing type captures heat from the exhaust gas and uses it to preheat the

incoming cold water as it passes through the secondary heat exchanger as illustrated below.

The condensing continuous

flow 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.

100cc/min maximum). It is not a water leak.

Do not plug or block the drain line as it must

always be allowed to freely flow.

(Installation example)

Condensate

comes out

from here.

The condensing continuous flow gas

water heater tends to show white steam.

After the exhaust gas passes through the

secondary heat exchanger, it becomes low in

temperature and moisture rich which 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.
