Problems resulting from scale formation

are not covered by the warranty.

Preventing damage from freezing ( P26)

Damage can occur from frozen water within the

device and pipes even in warm environments.

Be sure to read below for appropriate measures.

Repairs for damage caused by freezing are not

covered by the warranty.

Check ignition during use and extinction

after use.

Take necessary measures to prevent

freezing of water and leakage of gas when

leaving the unit unused for long periods of

time. ( P27)

Do not use parts other than those specified

for this equipment.

If it is snowing, check the air inlet, exhaust

gas vent and exhaust vent terminal for

blockage.

Do not disassemble the remote controller.

Do not use petrol, oil or fat detergents to

clean the remote controller.

This may cause deformation.

Do not get the remote controller wet.

Although it is water resistant, too much water can

cause damage.

Do not splash water on the remote

controller. Do not expose the remote

controller to steam.

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.

Drain pipe

(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.
