GENERAL INFORMATION

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

American National Standard Z21.10.1, CSA 4.1-M, Z21.10.3 and CSA 4.3 most

current editions at the time of manufacture. This is a category III water heater.

This water heater must be installed in accordance with local codes or, in the

absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest

Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).

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 held 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.

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-

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

DO NOT install the water heater in any location where gasoline or

flammable vapors are likely to be present.

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

(46 cm) above the floor and must 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) and/or in

Canada, CAN/CGA B149 Installation Codes (Latest Editions).

IMPORTANT

Before proceeding, please inspect the water heater and its components for

possible damage. DO NOT install any water heater with 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

This product contains one or more chemicals known to the State of

California to cause cancer, birth defects, or reproductive harm.

WARNING

Water heaters are heat producing appliances. To avoid damage or

injury, do not store materials against the water heater or vent-air intake

system. Use proper care to avoid unnecessary contact (especially by

children) with the water heater and vent-air intake components. UNDER

NO CIRCUMSTANCES MUST FLAMMABLE MATERIALS, SUCH AS

GASOLINE OR PAINT THINNER 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-

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

this water heater, 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.

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.

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,

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

that provide a minimum clearance of 6” beneath the water heater.

WARNING

Liquefied petroleum gases/propane gas 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 THE LEAKAGE IS

CORRECTED!

Installation (Locating The Water Heater) continued-

The water heater must be located close enough to the outside wall to keep the

venting distance within the maximum distance described in the installation

instructions. Locate the water heater as close as possible to the vent opening.

Read the venting section in this installation instruction manual before locating

the water heater.

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

water line connections and 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 adequately piped for proper drainage must be installed under the

water heater. The pan must not restrict combustion air flow. 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.

It is recommended that a minimum clearance of 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.

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

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, Sacramento, CA

95811.

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 the 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.

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 extending beyond the full

width and depth of the appliance by at least 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. The minimum clearances to combustibles for this

water heater are: 0 inch from the sides and rear, 5 inches (12.7 cm) from the
