the aged, or the disabled where water temperatures exceed 125° F (52°C).

Use anti-scald valves in the hot water system to reduce the risk of scalding at points of use such as lavatories, sinks and bathing facilities. Such precautions must be followed when this heater is operated in combination with dishwashing or space heating applications.

ØAs with all fuel burning equipment, this heater requires an adequate supply of air for combustion and ventilation. An insufficient air supply can result in poor combustion or the recirculation of the exhaust flue gases. Such a condition can cause sooting or present a fire hazard, which may result in serious bodily harm or death from asphyxiation.

MAKE SURE THE FLOW OF COMBUSTION

AND VENTILATION AIR IS NOT RESTRICTED.

ØIf this water heater has been exposed to flooding, freezing, fire or any unusual condition, do not put it into operation until it has been inspected and approved by a qualified

professional. THESE CONDITIONS CAN RESULT

IN UNSEEN INTERNAL DAMAGE and are not

subject to warranty coverage.

Safety Warnings

ØThere is a risk in using fuel-burning appliances such as water heaters. Areas that may not be suitable for water heater installation include those where flammable liquids, gasoline, solvents, adhesives, etc., or engine-driven equipment or vehicles are stored, operated or repaired. Due to the nature of air movement, flammable vapors can be carried some distance from the point of storage. The gas-fired water heater, pilot or main burner flame can ignite these vapors causing a flashback fire or explosion which may result in serious personal injury or death, as well as severe property damage.

If installation in a garage or shed is the only option, it is recommended that the water heater be elevated a minimum of 18" (45 cm) above the floor level. This may reduce BUT NOT ELIMINATE the risk of flammable vapors being ignited. Such installations must be protected from impact or physical damage caused from moving equipment or vehicles.

CHECK LOCAL CODES!

ØExposure to air borne chemicals can cause severe corrosion to the water heater and damage to the venting parts. Air containing vapors from cleaning solvents, pool chemicals, refrigerator or air conditioning refrigerants, laundry detergents or bleaches, waxes, spray can propellants, dry cleaning, photo processing liquids, calcium and sodium chloride

(softener salt) or other process chemicals are typical of compounds which are potentially corrosive.

ØProducts of this type should not be stored near the heater. Air containing these chemicals should not be used as supply to the heater. If necessary, uncontaminated air shall be obtained from remote or outside sources.

ØHYDROGEN GAS CAN BE PRODUCED IN A

HOT WATER SYSTEM. THIS CAN BE PROBLEMATIC IN SYSTEMS WITH LONG STANDBY PERIODS. HYDROGEN GAS IS EXTREMELY FLAMMABLE To reduce the risk of

injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will probably be an unusual sound, such as air escaping through the pipe as the water begins to flow. THERE SHOULD BE NO

SMOKING, OR OPEN FLAME NEAR THE FAUCET AT THE TIME THAT IT IS OPEN.

INSTALLATION INSTRUCTIONS

NOTICE

Before installing this water heater consideration and planning must be given to the following details:

ØHeater location. The vent blower can create air noise. Do not install near sleeping area, in a bedroom or bathroom;

ØLocation of the outside vent terminal; See “Venting” p. 7.

ØRouting and support of the vent piping; Figure 5 page 8.

ØHow and where to obtain combustion and ventilation air supply; See “Air Requirements” page 4.

ØPosition of water supply and placement of water piping for hot and cold water; See “Water Connections” page 10.

ØAccess for gas supply, electrical power, floor drain and service. See “Gas Service” pages 10 and 11.
