Installation
WARNING
Make sure the equipment has adequate
Ÿ
combustion air and proper ventilation.
Failure to do so may result in carbon
monoxide poisoning or death.
Keep the area around the water heater
Ÿ
clean. When the dust collects on the
flame, the sensor will turn off the error
code.
Place the equipment for easy repair and
Ÿ
maintenance.
If a leak occurs, it is recommended to
Ÿ
install a drain pan or other waterproof
protection under the water heater.
Failure to follow these warnings can
Ÿ
result in serious personal injury, death
and/or property damage.
NOTICE
The warranty does not cover damage
Ÿ
caused by water quality.
This water heater can only use drinking
Ÿ
water.
Do not introduce pool or hot
spring water or any chemically treated
water into the water heater.
For all other types of applications, the
Ÿ
water hardness level for single- family
applications should not exceed 7 grains
per gallon (120 ppm) or 4 grains (70
ppm) per gallon. The hardness of the
water can cause scaling and can
affect/damage the water heater. Hard
scale must be avoided or controlled by
proper water treatment.
The pH of the water must be between 6.5
Ÿ
and 8.5.
Well water must be disposed of.
Ÿ
When the water heater is installed in a
Ÿ
beauty salon, dry cleaner or in the air,
there is such a chemical. Whenever any
other location, the manufacturer
recommends direct venting. Certain
chemicals used in beauty salons or dry
cleaners may affect the flame sensor. In
this case underneath, the water heater
may not work properly.
12
Although the water heater is designed to
Ÿ
operate with minimal sound, the
manufacturer does not recommend
installing the unit on a wall close to the
bedroom or in a room for quiet study or
meditation.
Place the heater near the drain and the
Ÿ
water will not damage the surrounding
area. As with any water heating device,
there is a real possibility of leakage at
certain times during the life of the
product. The manufacturer is not
responsible for any water damage that
may occur. If you install a drain pan
under the unit, make sure it does not
restrict the flow of combustion air.
