FLAMMABLES

FLAMMABLE VAPORS

Vapors from flammable liquids will explode and catch fire causing death or severe burns.

Do not use or store flammable products such as gasoline, solvents or adhesives in the same room or area near the water heater.

Keep flammable products:

1.far away from heater

2.in approved containers,

3.tightly closed and

4.out of children’s reach.

This water heater has a main burner and an automatic ignition system. The ignition system:

1.can come on at any time and

2.will ignite flammable vapors.

Vapors:

1.cannot be seen,

2.are heavier than air,

3.go a long way on the floor and

4.can be carried from other rooms to the water heater by air currents.

Do not install this water heater where flammable products will be stored.

The water heater must be installed according to all local and state codes, or in the absence of local and state codes, the "National Fuel Gas Code”, ANSI Z223.1 (NFPA 54)-latest edition. Canadian installations must be performed in accordance with CAN/CSA-B149.1.

Note: In the State of California, the water heater must be braced, anchored, or strapped to avoid moving dur- ing an earthquake. Contact local utilities for code requirements in your area or call 1-800-456-9805 and request instructions.

Site Location

•Select a location near the center of the water piping system. The water heater must be installed indoors and in a vertical position on a level surface. DO NOT install in bathrooms, bedrooms, or any occupied room normally kept closed.

•Locate the water heater as close to the gas vent as practical. Consider the vent system piping and combustion air supply requirements when selecting the water heater location. The venting system must be able to run from the water heater to termination with minimal length and elbows.

•Locate the water heater near the existing gas piping. If installing a new gas line, locate the water heater to minimize the pipe length and elbows.

•The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., attics, basements, etc.) may require insulation of the water piping and drain piping to protect against freezing. The drain and controls must be easily accessible for operation and service. Maintain proper clearances as specified on the data plate.

•The operation of air-moving devices such as exhaust fans, ventilation systems, clothes dryers, fire-places, etc., can affect the proper operation of the water heater. Note: Special attention must be given to the location of these devices and the conditions they may create. Flow reversal of flue gases may cause an increase of carbon monoxide inside of the dwelling.

Important: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to corrosive elements in the atmosphere is excluded from warranty coverage.

The following types of installation (but not limited to the following) will require outdoor air for combustion due to chemical exposure, and may reduce but not eliminate the presence of corrosive chemicals in the air:

•Beauty shops

•Photo processing labs

•Buildings with indoor pools

•Water heaters installed in laundry, hobby or craft rooms

•Water heaters installed near chemical storage areas
