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.
Take necessary measures to prevent
freezing of water and leakage of gas when
leaving the unit unused for long periods of

If it is snowing, check the 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.
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.
Do not locate the remote controller near stoves or
ovens, this may cause damage or failure.
Do not run water through the unit when
unit is not on.
When discharging hot water, make sure the unit is ON.
If water is run through the unit with the unit
OFF, water may condense inside the unit and cause
incomplete combustion or damage to the internal
electrical components.
For single-handle xtures or valves, discharge
water setting the handle completely
to the water side.

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 drain pipe (approx.
2 gallons/hour (7.5 liters/hour) maximum). It is not a
water leak. Do not plug or block the drain line as it
must always be allowed to freely ow.
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.
Drain pipe
(Installation example)
Overview of Condensing Tankless Gas Water Heater
This water heater is a high efciency, fully condensing appliance. Unlike a traditional tankless 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 tankless 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.

* 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.
Freezing cannot be prevented when the power plug is unplugged. Do not remove the power
plug from the wall outlet.
Freezing will be prevented regardless of whether the operation switch is ON or OFF.
Take the measures below for extremely cold temperatures*.
Outside temperature including wind chill factor less than -30°F (-35°C).
- When supplying combustion air from the indoors, the room temperature must be greater than
32°F (0°C) to prevent freezing and the room inside must not have negative pressure.
This method can protect not only the heater, but also the water supply, water piping and mixing valves.
1. Turn off the power.
2. Close the gas supply valve.
3. Open a hot water xture, and keep a small stream of hot water

* If there is a mixing valve, set it to the highest level.
* When linking multiple units, discharge water equivalent to

4. The ow may become unstable from time to time.
Check the ow 30 minutes later.
* In general, it is not advisable to run water through the unit when
it is OFF ( p. 6), but in this case freeze prevention is more important.
* Remember to set mixing valves and xtures to their original levels before using the unit again
to prevent scalding.
* If there is still a risk that the unit will freeze, drain the unit as shown on the pages 19, 20.
Preventing Damage from Freezing-1
Freezing is prevented within the device automatically by the freeze-prevention heater.
If water will not flow because it is frozen
1. Close the gas and water valves.
2. Turn off the power button.
3. Open the water supply valve from time to time to check whether water is running.
4.
When the water is owing again, check for water leaks from the equipment and piping before using.
If the heater or the piping is frozen, do not use the heater or it may get damaged.
CAUTION
* In normal operation, freezing is prevented within the device automatically unless the outside
temperature without wind is below -30°F (-35°C).
- When supplying combustion air from the indoors, the room temperature must be greater than
32°F (0°C) to prevent freezing and the room inside must not have negative pressure.
* The freeze prevention heaters will not prevent the plumbing external to the unit from freezing.
Protect this plumbing with insulation, heat tape or electric heaters, solenoids, or pipe covers.
If there remains a freezing risk, contact the nearest Electrolux agent.
