DOMESTIC TANKLESS GAS WATER HEATER USER’S MANUAL EZ Deluxe Read the installation instructions before installing the appliance. Read the user’s instructions before powering on the appliance. DIRECT VENT CONCENTRIC EXHAUST MODEL ISO9001 Certified 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.
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.
KEY WORDS USED IN THIS MANUAL All safety messages will use either the word “DANGER”, “WARNING”, “CAUTION” or “NOTICE”. These words mean: DANGER - An imminently hazardous situation that will result in death or serious injury. WARNING - A potentially hazardous situation that could result in death or serious injury and/or damage to property. CAUTION - A potentially hazardous situation that may result in minor or moderate injury.
WARNING! Gasoline, as well as other flammable materials and liquids (adhesives, solvents, paint thinners etc.), and the vapors they produce are extremely dangerous. DO NOT handle, use or store gasoline or other flammable or combustible materials anywhere near or in the vicinity of a water heater or any other appliance. Be sure to read and follow the labels on the water heater, as well as the warnings printed in this manual. Failure to do so can result in property damage, bodily injury or death.
INSTALLATION: Contact your local gas dealer or utility company specialist for a qualified engineer to evaluate your plans and always use a qualified technician to install the gas water heater.

DANGER: When this heater is in use, there is obviously a combustion process which generates heat to make hot water. The combustion of almost all combustible materials and flammable gases of any kind typically consumes a large amount of oxygen and in turn this combustion process produces many different by-products in the smoke (exhaust) which include Carbon Monoxide. Regardless of how clean the combustion process is, there are always exhaust gasses that are emitted at some level.
NOTICE: This heater is not designed to be mounted in areas outdoors or unheated structures if temperatures can drop below freezing. When the temperature of the room in which this heater is mounted drops below freezing the residual water must be drained from this unit. WARNING: FOR YOUR SAFETY, READ BEFORE OPERATING If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance does not have a pilot.
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.
MULTIPLE REDUNDANT SAFTEY PROTECTION SYSTEMS: Multiple safety protection devices. For example, in case of a sudden flame out or lack of water supply or electrical power, the systems provide an instantaneous automatic shut-off. ADVANCED DIGITAL CONSTANT TEMPERATURE TECHNOLOGY: ”Set it and forget it” technology. Set your EZ DELUXE tankless water heater to the desired temperature and the computer controlled system will keep the flowing water at a constant temperature, no matter the change in water flow.
