Be sure to read below for appropriate measures.

Repairs for damage caused by freezing are not

covered by the warranty.

Do not use parts other than those specified

for this equipment.

Power must be switched on at all times for

antifrost protection to work.

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 benzene, oil or fat detergents

to clean the remote controller.

This may cause deformation.

Do not get the remote controller wet.

Heater

Water is heated

using the exhaust

gas which is about

The condensing 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. 75cc

/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)

Overview of Condensing Gas Water Heater

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

condensing appliance 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 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.

Condensate

comes out

from here.

During combustion, white

steam may often be seen.

This is normal.
