EZ TANKLESS EZ Ultra, User Manual

Page: 2 / 26

NOTICE:
For your safety and the safety of others, this heater cannot be connected to an
existing natural draft exhaust. Only the sealed-joint concentric intake/exhaust components
made specifically for this heater can be used. There are no compromises, do not attempt to
modify or substitute the exhaust/intake components of this heater! Multiple advanced
redundant electrical safety devices are integrated into the electronics of this heater, they
cannot be disconnected or bypassed and they are designed to detect any and all
modifications and incorrect connections. These devices will prevent the heater from
turning on. This heater will not run without the exhaust/intake pipe being connected.
PLEASE:
Do not proceed with the installation of this heater until you are familiar with the concept of
concentric intake/exhaust direct vent technology. This exhaust system is actually two pipes
in one. Most manufacturers have switched to this technology for many reasons. Maximum
efficiency and safety are two primary reasons. As this technology is relatively new, it is not
uncommon for users to not understand the concepts. If you are replacing an existing tank
type heater, there is no possible way to use the old exhaust pipes. It will not work, do not
try! With “Direct Vent” heaters made by any manufacturer, the intake air is drawn into
the heater from outdoors via one chamber or pipe, the exhaust exits via a second chamber
or pipe. With the EZ ULTRA model, the intake combustion air comes from outside via the
outer concentric chamber of our dual chamber pipe and the exhaust exits through the
inner part of the pipe.
If you are uncertain of what this technology means to you and how it saves you energy,
please read this manual thoroughly and review the information and videos on our website
