GENERAL INFORMATION

This gas-fired water heater is design certified by CSA International under the

applicable American National Standard, Z21.10.1 or Z21.10.3-(as indicated on

the rating plate), or CSA 4.1-(as indicated on the rating plate), available from

CSA International, 8501 East Pleasant Valley Road, Cleveland, OH U.S.A.

44131-5575.

This water heater must be installed in accordance with local codes. In the

absence of local codes, it must be installed in compliance with the National

Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1

Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2 Propane

Installation Code (Latest Edition). The warranty for this water heater is in

effect only when the water heater is installed, adjusted, and operated in

accordance with these Installation and Operating Instructions. The

manufacturer will not be liable for any damage resulting from alteration and/or

failure to comply with these instructions.

This water heater is not design certified for installation in a mobile home. Such

an installation may create a hazardous condition and will nullify the warranty.

This water heater has been designed and certified for the purpose of heating

potable water. The installation and use of this water heater for any purpose

other than the heating of potable water may cause damage to the water

heater, create a hazardous condition, and nullify the warranty.

Do not use this appliance if any external part to the tank has been submerged

in water. You should contact a qualified service technician to inspect the

appliance and to replace any part of the control system including the

combination gas control which has been submerged in water. See the Gas

Connections section of this manual before servicing or replacing a water

heater that has had any external part to the tank submerged in water.

CAUTION

Incorrect operation of this appliance may create a hazard to life and

property and will nullify the warranty.

WARNING

Prior to connecting the gas supply line to a gas fired water heater,

ensure that the gas supply line does not have moisture/water or

dirt/scale inside the gas line. Commonly this check is done at the

lowest point in the gas distribution system prior to gas burning

appliances.

DANGER

Do not store or use gasoline or other flammable, combustible, or

corrosive vapors and liquids in the vicinity of this or any other

appliance.

General Information continued-

This water heater has been manufactured for operation at altitudes from sea

level to 2000 feet (610m). For use of this appliance at an elevation greater

than 2000 feet (610m), contact the dealer or manufacturer listed on the rating

this appliance may create a hazard to life and property.

Make sure that you check the rating plate and combination gas control on the

water heater to be certain that the type of gas being supplied corresponds with

the marking on the rating plate and combination gas control.

A sacrificial anode(s) is used to extend tank life. Removal of any anode,

except for inspection and/or replacement, will nullify the warranty. In areas

where water is unusually active, an odor may occur at the hot water faucet

due to a reaction between the sacrificial anode and impurities in the water. If

this should happen, an alternative anode(s) may be purchased from the

supplier that installed this water heater. This will minimize the odor while

protecting the tank. Additionally, the water heater should be flushed with

appropriate dissolvers to eliminate any bacteria.

INSTALLATION

Locating the Water Heater

IMPORTANT

Before proceeding, please inspect the water heater and components for

possible damage. DO NOT install any damaged components. If damage is

evident then please contact the supplier where the water heater was

purchased, or the manufacturer listed on the rating plate for replacement

parts.

WARNING

Water heaters are heat producing appliances. To avoid damage or

injury there must be no materials stored against the water heater or

vent-air intake system and proper care must be taken to avoid

unnecessary contact (especially by children) with the water heater and

vent-air intake components. UNDER NO CIRCUMSTANCES SHALL

FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT

THINNER TO BE USED OR STORED IN THE VICINITY OF THIS

WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY

LOCATION FROM WHICH FUMES COULD REACH THE WATER

HEATER OR VENT-AIR INTAKE SYSTEM.

Installation (Locating the Water Heater) continued-

This water heater MUST be installed indoors out of the wind and

weather.

This water heater MUST NOT be installed in any location where gasoline

or flammable vapors are likely to be present, unless the installation is

such to eliminate the probable ignition of gasoline or flammable vapors.

Water heaters in residential garages must be installed so that all

burner(s) and burner ignition device(s) are located not less than 18

inches (45.7 cm) above the floor and be located, or protected, to avoid

physical damage. For other installations refer to local codes. In the

absence of local codes, the water heater must be installed in compliance

with the National Fuel Gas Code, (ANSI Z223.1- Latest Edition), or in

Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition)

or CAN/CGA B149.2 Propane Installation Code (Latest Edition).

The location of this water heater is of the utmost importance. Before installing

this water heater, you should read the Installation section of these instructions.

After reading these Installation and Operating Instructions, select a location for

the water heater where the floor is level and is easily accessible to gas and

water supply lines. DO NOT locate the water heater where water lines

could be subjected to freezing temperatures. Make sure the cold water

pipes are not located directly above the gas control so that condensate

during humid weather does not drip on the controls.

Note: For California installation, this water heater must be braced,

anchored, or strapped to avoid falling or moving during an earthquake.

See instructions for correct installation procedures. Instructions may be

obtained from DSA Headquarters Office, 1102 Q Street, Suite 5100,

Sacramento, CA 95811.

Water heater corrosion and component failure can be caused by the heating

and breakdown of airborne chemical vapors. Examples of some typical

compounds that are potentially corrosive are: spray can propellants, cleaning

solvents, refrigerator and air conditioning refrigerants, swimming pool

chemicals, calcium and sodium chloride, waxes and process chemicals.

These materials are corrosive at very low concentration levels with little or no

odor to reveal their presence. NOTE: DAMAGE TO THE WATER HEATER

CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY

THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF

EXPOSURE HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY

CORROSIVE COMPOUNDS IN THE VICINITY OF THE WATER HEATER.

Installation (Locating the Water Heater) continued-

Proper venting practices must be considered when selecting a location for this

water heater. For exact venting specifications, please consult the Venting

section, of these Installation and Operating Instructions.

This water heater must be located in an area where leakage of the tank, water

line connections, or the combination temperature and pressure relief valve will

not result in damage to the area adjacent to the water heater or to lower floors

of the structure. When such locations cannot be avoided, a suitable drain pan

must be installed under the water heater. The drain pan must have a minimum

length and width of at least 4 in. (10.2 cm) greater than the diameter

of the water heater and must not restrict proper combustion air flow to the

water heater. The drain pan, as described above, can be purchased from your

plumbing professional. The drain pan must be piped to an adequate drain.

The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for

proper drainage.

WARNING

Liquefied petroleum gases/propane gases are 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. Before lighting, smell all around the appliance area for gas.

Be sure to smell next to the floor.

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 neighbor’s telephone.

Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

WARNING

DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE

NOT CERTAIN OF THE FOLLOWING:

•Liquefied petroleum gases/propane gas and natural gas have an

odorant added by the gas supplier that aids in detection of the gas.

•Most people recognize this odor as a “sulfur” or “rotten egg” smell.

•Other conditions, such as “odorant fade” can cause the odorant to

diminish in intensity, or “fade”, and not be as readily detectable.

•If you have a diminished sense of smell or are in any way unsure of

the presence of gas, immediately contact your gas supplier from a

neighbor’s telephone.

Gas detectors are available. Contact your gas supplier or plumbing

professional for more information.

Installation (Locating the Water Heater) continued-

It is recommended that a minimum clearance of four (4) inches (10.2 cm) be

provided on the side of the water heater for servicing and maintenance of the

combination temperature and pressure relief valve.

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.

Minimum Clearances

This installation must allow access to the front of the water heater and

adequate clearance must be provided for servicing and operating this water

heater. The water heater may be installed on either a combustible or non-

combustible floor. If the water heater is to be installed directly on carpeting, it

must be installed on top of a metal or wood panel (or equivalent) extending

beyond the full width and depth of the appliance by at least three (3) inches

(7.6 cm)in any direction or, if the appliance is to be installed in an alcove or

closet, the entire floor must be covered by the panel, increase distances to

provide clearance for servicing. If the rating plate or the label on the front

of the water heater specifies minimum clearances less than those listed

in the below table, the water heater may be installed in accordance with

the minimum clearances listed on the rating plate or the label on the

front of the water heater.

If it is necessary to install this water heater in an alcove, use the clearances

listed in the following table and Figure 1.

Figure 1

WARNING

Failure to adhere to these installation and operating instructions

may create a hazard to life and property and will nullify the

warranty.

Venting

This water heater has been shipped with a draft diverter for which it was designed with

reference to the horizontal and vertical planes, its certified category I, per latest ANSI Z

21.10.3-2015.CSA 4.3-2015 revision. Refer to the latest edition of the National Fuel

Gas Code (ANSI Z223.1-latest edition), or in Canada, the Natural Gas and Propane

Installation Code (B149.1-00 latest edition). If removed, the draft diverter must be

replaced in the same position and secured to the jacket top by which it was installed.

WARNING

The venting system must be installed properly following all local codes

or in the absence of local codes, the latest edition of the National Fuel

Gas Code (ANSI Z223.1- latest edition), or in Canada, The Natural Gas

and Propane Installation Code (B149.1-00 latest edition). Failure to

properly install the venting system could result in property damage,

personal injury, or death.

WARNING

Carefully inspect the venting system of a replacement water heater installation

before connecting to the venting system. All joints in the vent connector must be

securely fastened with screws and fit tightly together.

Inspect the venting

system for signs of deterioration (rust and perforation) and replace any sections

that are not in good condition.

The chimney must be lined and in good condition.

Check to make sure the

venting system is properly sized for the water heater. If the venting system was

previously sized for another gas appliance that has been removed, the venting

system may now be too large. Refer to the latest edition of the National Fuel

Gas Code (ANSI Z223.1-

latest edition), or in Canada, the Natural Gas and

Propane Installation Code (B149.1-

00 latest edition) for the correct sizing of

venting systems and common venting with another gas appliance.

Do not vent this water heater into the venting system of another gas appliance

designed to vent under positive pressure.

The water heater should be installed as close as practical to the venting system

to minimize the vent connector length required. Refer to loc

al codes for the

distance limitations on vent connector lengths.

At the completion of the water heater installation, the burner and venting system

must be checked for proper operation with all other commonly vented

appliances in operation. Check for spillage of flue products around the outside

relief opening of the draft hood after several minutes of operation. The flame

from a match should be drawn into the draft hood. Do not use the water heater

or connected equipment if spillage is detected until the problem is corrected.

Refer to the latest edition of the National Fuel Gas Code, or in Canada, the

Natural Gas and Propane Installation Code for complete details on the

“Procedure to Be Followed to Place Equipment in Operation”.

Venting continued-

This water heater must be connected to a lined masonry chimney or venting

system approved by local codes or ordinances. The vent connector used to

attach the draft diverter outlet to the chimney or approved vent must be of the

same diameter as the draft diverter outlet or larger. For proper venting in

certain installations, a larger vent connector may be needed. Consult venting

tables in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code

and CAN/CGA (B149.1 or B149.2-latest editions) Natural Gas and Propane

Installation Code, or local code officials for proper application for your area.

Combustion Air Supply

Provide adequate air for combustion and ventilation. An insufficient

supply of air will cause recirculation of combustion products resulting in

air contamination that may be hazardous to life. Such a condition often

will result in a yellow, luminous burner flame, causing carboning or

sooting of the combustion chamber, burners and flue tubes with possible

damage to the water heater. When an exhaust fan is installed in the

same room with a water heater, sufficient openings for air must be

provided in the walls. Undersized openings will cause air to be drawn

into the room through the chimney, causing recirculation of combustion

products.

Confined Spaces

Confined spaces are spaces defined as having less than 50 ft.3/1000 BTU

(1.41m3/.29kw) per hour.

WARNING

Liquefied petroleum gases/propane gases are 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. Before lighting, smell all around the appliance area for gas.

Be sure to smell next to the floor.

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 neighbor’s telephone.

Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

IMPORTANT

The flow of combustion and ventilating air must not be obstructed.
