WARNING
Water temperatures over 52°C (125°F)
can cause severe burns instantly or
death from scalding. The water tem-
perature is set at 49ºC (120ºF) from the
factory to minimize any scalding risk.
Before bathing or showering always
check the water temperature.
Do not store or use gasoline or other
flammables, vapors, or liquids in the
vicinity of this appliance.
Do not reverse the water and/or gas
connections as this will damage the gas
valves and can cause severe injury or
death. Follow the diagram on pg. 12
when installing your water heater:
Do not use this appliance if any part has
been in contact with or been immersed
in water. Immediately call a licensed
plumber, a licensed gas fitter, or a pro-
fessional service technician to inspect
and/or service the unit if necessary.
Do not disconnect the electrical supply if
the ambient temperature will drop below
freezing. The Freeze Prevention System
only works if the unit has electrical
power. The warranty will not be covered
if the heat exchanger is damaged due
to freezing. Refer to the section on the
Freeze Protection System on pg. 20 for
more information. •

INSTALLATION
All gas water heaters require careful and correct installation
to ensure safe and efficient operation. This manual must be
followed exactly. Read the “Safety Guidelines” section at the
beginning of this manual.
CAUTION
The warranty will not cover damage
caused by water quality. Water hard-
ness that leads to scale formation and/or
corrosion may affect/damage the water
heater. Hard water scaling and/or cor-
rosion must be avoided or controlled by
proper water treatment.
The manufacturer recommends using
the direct-vent kit, when the water heater
is installed in a beauty salon. Some
chemicals used in a beauty salon may
affect the flame sensor. Water heater
may not work properly.
Although the 910 is designed to operate
with minimal sound, the manufacturer
does not recommend installing the unit
on a wall adjacent to a bedroom, or a
room that is intended for quiet study or
meditation, etc.
Locate your heater close to a drain
where water leakage will not do damage
to surrounding areas. As with any water
heating appliance, the potential for leak-
age at some time in the life of the prod-
uct does exist. The manufacturer will not
be responsible for any water damage
that may occur. If you install a drain pan
under the unit, ensure that it will not
restrict the combustion air flow. •

WARNING
The 910 weighs 50.8Kg (112 lbs.).
Ensure that any and all support struc-
tures (whether it is installed on a wall,
on a support stand, etc.) have enough
strength to support and hold the 910.
When handling the 910, do not place
your hands inside the flue collar. Injury
may result.
The manufacturer does not recommend
installing unit in an attic due to safety
issues. If you install your 910 in an
attic:
Make sure your unit will have enough
combustion air and proper ventilation.
Keep the area around your water heater
clean. When dust collects on the flame
sensor, the water heater will shut down
on errors.
If the above conditions cannot be met,
use the direct-vent conversion kit TM-
DV50.
Locate unit for easy access for service
and maintenance.
A drain pan is required to be installed
under the water heater in case of leaks.
