Introduction

!WARNING

Read and Review this entire Manual with special emphasis on the Venting Sections (Pages 8-12) and Operation Section (Pages 14-17) prior to any installation work.

LOCAL INSTALLATION REGULATIONS

This water heater must be installed in accordance with these instructions, local codes, utility company requirements and/or, in the absence of local codes, the latest edition of the National Fuel Gas Code, ANSI Z223.1 in the United States, or CGA/CAN B149 Installation Codes in Canada.

LOCATION

A.This water heater is of the direct vent design. All air for combustion and all products of combustion are routed through the venting system, directly from and to the outside of the building.

The water heater should be installed in a clean, dry location as close as practical to the gas vent terminals. Long hot water lines should be insulated to conserve water and energy. The water heater and water lines should be protected from exposure to freezing temperatures.

B.A gas fired water heater should not be installed in a space where liquids which give off flammable vapors are to be used or stored. Such liquids include gasoline, LP gas (butane and propane), paint or adhesives and their thinners, solvents or removers. Because of natural air movement in a room or other enclosed space, flammable vapors can be carried some distance from where their liquids are being used or stored. The open flame of the water heater’s intermittent pilot or main burner can ignite these vapors causing an explosion or fire which may result in severe burns or death to those in range, as well as property damage. For these reasons, installation of a gas fired water heater in a garage is not desirable.

!WARNING

If a location in a garage is the only alternative, the gas water heater should be installed so that the open flame of the pilot and main burner are no less than 18 inches above the garage floor.The water heater must be located or protected so it is not subject to physical damage by moving vehicles or area flooding. Raising the gas fired water heater will reduce BUT NOT eliminate the possibility of light- ing the vapor of any flammable liquids which may be improperly stored or accidentally spilled.

C.All models are certified for installation on combustible floors and in alcoves. The minimum side and top clearance to walls and ceiling for providing protection of combustible materials are shown on the water heater’s rating label. A front clearance of 18 inches (46 cm) should be provided for adequate inspection and servicing.

If the water heater must be installed on carpeting, place a metal or wood panel beneath water heater extending beyond its full width and depth at least 3 inches (7.6 cm) in all directions. If the water heater is installed in an alcove, the entire floor must be covered by the panel.

The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent

!CAUTION

to it or to lower floors of the structure.When such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater. The pan MUST NOT restrict the flow of combustion air flow to bottom of water heater.

NOTICE: Auxiliary catch pan installation MUST conform to the ap- plicable local codes.

D.RESTAURANTS — If the water heater is to be installed in a restau- rant or other location where the floor is frequently cleaned, it must be elevated to provide at least six inches (15 cm) of clearance from the floor to comply with NSF International recommendations.

E.CORROSIVE ATMOSPHERES — The heater should not be installed near an air supply containing halogenated hydrocarbons. For example, the air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches or swim pool chemicals often contain such hydrocarbons. The air there may be safe to breathe, but when it passes through a gas flame, corrosive elements are released that will shorten the life of any gas burning appliance. Propellants from common spray cans or gas leaks from refrigeration equipment are highly corrosive after passing through a flame. The lim- ited warranty is voided when failure of water heater is due to a corrosive atmosphere. (Refer to the Certificate of Limited Warranty for complete terms and conditions.)
