WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be
considered when selecting the water temperature
setting. Water temperatures above 125°F(51°C) can
cause severe burns or death from scalding. The
thermostat is adjusted to 110°F(43°C) when shipped
from the factory. Be sure to read and follow the
warnings outlined on the label pictured below.
The chart shown to the right may be used
as a guide in determining the proper water
temperature for your home.
DANGER: Households with small children,
disabled, or elderly persons may require a

delivered, turn on a hot water faucet and place
a thermometer in the water stream and read the
thermometer.
The temperature of the water at the outlet of
the water heater can be regulated by setting
the temperature on the included remote control
or using the Eccotemp SMARTHOME app. The
default temperature was set at 110°F(43°C) before
it was shipped from the factory.
NOTICE: When this water heater is supplying
general purpose hot water requirements for
use by individuals, a thermostatically controlled
temperature is recommended to reduce the risk
of scald injury. Contact a licensed plumber or the
local plumbing authority for further information.
NOTICE: The factory setting allows operating
temperatures between 78°F(26°C) and
140°F(60°C).
NOTICE: This is a remotely controlled
temperature tankless water heater. This means
that the temperature must be set from the

The water heater must be vented to the outdoors. Termination must be 50 cm away from any
obstructions and the termination must be at least 5 cm away from the wall, as described in these

municipality if additional venting is needed.
The included vent termination should be used. If not, a termination hood with a screen must be used.
(Refer to page 19). Do not remove the terminal guard. The terminal outlet must not be covered by
anything.
Use a vent pipe with an antidisconnection

Draining the Condensate
In certain conditions, installations in unconditioned space or having long horizontal or vertical
runs may accumulate condensate.
Condensate is known to be acidic; refer to local, state (provincial) or federal codes for proper
handling methods.
In order to prevent condensate from draining back into the water heater, we recommend a
condensate trap and drain to be installed in a horizontal vent section as close as practical to
the water heater vent connection.
NOTICE: Not following proper condensate procedures will void warranty.
