FEATURES:
This tankless water heater uses the Direct Vent Exhaust System. This is absolutely the
safest and most economical ventilation method in use among tankless water heaters. This
method uses a dual-chamber intake/exhaust pipe and a forced air system. This model is
suitable for showering, using the sink, a clothes washing machine or even your
dishwasher. This tankless water heater uses all of the safest and most efficient technologies
available today, making it a leader in its class of tankless water heaters.
DIRECT VENT CONCEPT:
Since this product adopts the method of forced exhaust and fresh air supply for
combustion, this air needed for combustion is completely from outdoors, and the waste
gases produced by combustion are forcedly discharged to the outdoors, therefore, the air
indoors won’t be consumed and polluted. This removes some of the dangerous factors
related to the potential of an insufficient oxygen supply and Carbon Monoxide poisoning.
This model can be installed in the home with a horizontal exit directly to an outside wall.
CONVENIENT ADJUSTMENT:
This heater features a fully automatic ignition that is controlled by a flow sensor, which is
triggered by the movement of water when a faucet or water tap is opened.
Water volume and gas flow are regulated independently, allowing for a very accurate
control of the desired pre-set water temperature. To save energy, to comply with US
federal and state plumbing codes, and for liability reasons, the manufacturer of this water
heater has preset the temperature control to 48C (120F) and this is the default setting. The
temperature can be raised manually for single use purposes, but once the water is shut-off,
the setting default returns to the 120F setting as dictated by state and federal law.
Furthermore, to prevent tampering and danger of scalding, the pre-set temperature
cannot be raised manually when the heater is in operation. The water flow must first be
shut-off before the temperature can be raised via the control panel located on the front of
this unit.
ENERGY SAVINGS AND HIGH EFFICIENCY:

designed by using an advanced combustion theory, incorporating features of high
efficiency and clean and complete combustion performance.
