IMPORTANT INFORMATION
The equipment must be installed in accordance with those installation regulations required in the area where the installation is to be made. These regulations must be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made. All wiring on water heaters installed in the USA must be in accordance with the National Electrical Code and/or local regulations; or in Canada, installed in accordance with the Canadian Electrical Code and/or local regulations.
The following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels, or to important information concerning product life.
DANGER
Indicates an imminently hazardous situation, which, if not avoided, will result in death, serious injury, or substantial property damage.
CAUTION
Indicates a potentially hazardous situation, which, if not avoided, could result in death, serious injury, or substantial property damage.
WARNING
Indicates a potentially hazardous situation, which, if not avoided, may result in moderate, or minor injury or property damage.
NOTICE
Indicates special instructions on installation, operation or maintenance, which are important but not related to personal injury hazards.

GENERAL INFORMATION
For your family’s comfort, safety, and convenience, we recommend this water heater be installed and serviced by a plumbing professional.
WARNING
To avoid damage or injury, there must be no materials stored against the indirect water heater and proper care shall be taken to avoid unnecessary contact (especially by children) with the indirect water heater. Do not store or use gasoline or other flammable liquids in the vicinity of this water heater or any other appliance.
DANGER
DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors and/or liquids in the vicinity of this or any other appliance.
IF YOU SMELL GAS:
DO NOT try to light any appliance.
DO NOT touch any electric switch; do not use any telephone in your building.
Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s instructions.
If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
Liquefied petroleum gas/propane gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets, and areas below ground level will serve as pockets for accumulation of leaking gas.
This water heater is supplied with an adjustable thermostat to control water temperature. Hot water temperatures required for automatic dishwasher and laundry use can cause scald burns resulting in serious personal injury and/or death. The temperature at which injury occurs varies with the person’s age and the time of exposure. The slower response time of disabled persons increases the hazards to them. NEVER allow small children to use a hot water tap or to draw their own bath water. NEVER leave a child or disabled person unattended in a bathtub or shower.
WARNING
Installation is not complete unless a pressure and temperature relief valve is installed into the side of the water heater. This water heater contains very hot water under high pressure. Do not unscrew any pipe fittings or attempt to disconnect any components of this water heater without positively assuring the water is cool and has no pressure. Always wear protective clothing and equipment when installing, starting up, or servicing this water heater to prevent scald injuries. Do not rely on the pressure and temperature gauges to determine the temperature and pressure of the water heater. This water heater contains components that become very hot. Do not touch any components unless they are cool. Improper installation, adjustments, alteration, service or maintenance can cause property damage, personal injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or death. Read and understand all instructions, including all those contained in component manufacturer’s manuals, which are provided with the appliance before installing, starting-up, operating, maintaining, or servicing this appliance. Keep this manual and literature in legible condition and posted near the appliance for reference by owner and service technician. This water heater requires regular maintenance and service to operate safely. Follow the instructions contained in this manual. Installation, maintenance, and service must be performed only by an experienced, skilled, and knowledgeable installer or service agency.

WARNING
It is the responsibility of the installing contractor to see that all controls are correctly installed and are operating properly when the installation is complete.
DO NOT operate the water heater with jumped out or absent controls or safety devices. DO NOT tamper with or alter the water heater and/ or controls.
DO NOT operate the water heater if any external part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system that was under water.
DO NOT install this water heater on carpeting. This water heater is suitable for installation on combustible flooring.
DO NOT operate this water heater without first being certain it is filled with water.
Flammable items, pressurized containers, or any other potential fire hazardous articles must never be placed on or adjacent to the heater. Containers of flammable gases should not be stored or used in the same room with this water heater. Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend that the water faucet be opened for several minutes at the kitchen sink before you use any electrical appliance that is connected to the hot water system. If hydrogen is present, there will be unusual sounds such as air escaping through the pipes as hot water begins to flow. Do not smoke or have open flame near the faucet at the time it is open.
CAUTION
The maximum boiler water supply temperature to the indirect heat exchanger must not exceed 200°F (93°C).
NOTICE
Insulation blankets are not required for this water heater. This water heater meets or exceeds the ASHRAE/IES 90.1b standards with respect to insulation and standby loss requirements.
NOTICE
The maximum heat transfer through the coil (heat input) of the water heater at 200°F (93°C) boiler water supply temperature and 210°F potable water temperature is 94,000 Btu/hr. Potable water temperature is limited to below 210°F and nominal water containing capacity is less than 120 gallons for all indirect models. Accordingly, per Part HLW-101.2, Section IV of the ASME Boiler and Pressure Vessel Code, all indirect products are therefore exempted from compliance with the code.
