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.

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
200˚C
.
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.
Drain pipe
(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.
