GENERAL INFORMATION

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

American National Standard Z21.10.1 -(as indicated on the rating plate) and

CSA 4.1-M-(as indicated on the rating plate).

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 part 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.

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.

CAUTION

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

property and will nullify the warranty.

DANGER

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

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

General Information continued-

A sacrificial anode is used to extend tank life. The removal of this anode, for any

reason, 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 the impurities in the water. If this should happen, an alternative anode 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.

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.

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.

CAUTION

The National Fuel Gas Code (ANSI Z233.1-or latest edition) and

CAN/CGA (B149.1-or latest edition), expressly prohibits the installation

of a water heater in a garage, unless the unit is installed so that the

burner and ignition devices are at least eighteen (18) inches (46 cm)

above floor level and protected to avoid damage by a moving vehicle.

Installation (Locating The Water Heater) continued-

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.

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 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. 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 drain pan must be no greater than 1-½ inches (3.8 cm) deep and have a

minimum length and width of at least four (4) inches (10.2 cm) measured from the

jacket of 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 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.

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.
