CONGRATULATIONS!

You have purchased one of the finest water heaters on the

market today!

This installation, operation, and instruction manual will

explain in detail the installation and maintenance of your new

indirect water heater. We strongly recommend that you

contact a plumbing professional for the installation of this

water heater.

We require that you carefully read this manual, as well as the

enclosed warranty, and refer to it if questions arise. If you

have any specific questions concerning your warranty, please

consult the plumbing professional from whom your water

heater was purchased. For your records we recommend that

you write the model, serial number and installation date of

your water heater in the back of this manual.

This manual should be kept with the water heater.

We’re committed to providing you with the finest water heater

made.

SECTION I

IMPORTANT INFORMATION

-READ CAREFULLY-

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.

CAUTION

The maximum boiler water supply temperature to the indirect heat

exchanger must NOT exceed 240°F (115°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.

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, may result in

moderate, or minor injury or

property damage.

WARNING

Indicates a potentially

hazardous situation, which,

if not avoided, could result

in death, serious injury, or

substantial property

damage.

NOTICE

Indicates special

instructions on installation,

operation or maintenance,

which are important but not

related to personal injury

hazards.

Important Information continued-

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.

Important Information continued-

WARNING

Installation is not complete unless a pressure and temperature

relief valve is installed into the side of the water heater. See the

Water Connections section of this manual for details.

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.

To comply with NSF requirements this water heater is to be:

a) Sealed to the floor with sealant, in a smooth and easily

cleanable way, or

b) Installed with an optional leg kit that includes legs and/or

extensions that provide a minimum clearance of 6” beneath

the water heater.

Important Information continued-

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 jumpered 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.

This water heater is suitable for installation on combustible

flooring. DO NOT install this water heater on carpeting.

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.

NOTICE

If the boiler takes longer to heat up from a cold start than the water

availability as noted above, hot water shortage may occur.

Hot water availability is based off drawing 80% of the heated tank

volume at 4 gallons per minute flow rate.

The maximum heat transfer through the coil (heat input) of the

water heater at 240°F boiler water supply temperature and 210°F

potable water temperature is 94,100 Btu/hr for residential models

and 180,300 Btu/hr for commercial models. Potable water

temperature is limited to below 210°F and nominal water-containing

capacity is below 120 gallons for all indirect-fired models.

Accordingly, per Part HLW-101.2, Section IV of the ASME Boiler

and Pressure Vessel Code, all indirect-fired products listed are

exempted from compliance with the code.

SECTION III
