Location Requirements

WARNING

Carbon Monoxide Poisoning Hazard

Do not install in a mobile home.

Doing so can result in carbon monoxide poisoning and death.

The FVIR System is designed to reduce the risk of flammable vapor-related fires. Flammable liquids (such as gasoline, solvents, propane, etc,) emit flammable vapors which can be ignited by a gas water heater’s hot surface igniter or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area.

FIGURE 8.

FV Sensor

This heater is equipped with a FV sensor for detecting the presence of flammable vapors. When the sensor detects those vapors, the unit will shut down and not operate. Should this happen, please refer to the troubleshooting guide on pages 38-40 (numbers 9,11,12). Even though this water heater is a flammable vapors ignition resistant water heater and is designed to reduce the chances of flammable vapors being ignited, gasoline and other flammable substances should never be stored or used in the same vicinity or area containing a gas water heater or other open flame or spark producing appliance.

WARNING

FLAMMABLES Flammable Vapors

FIRE AND EXPLOSION HAZARD

Can result in serious injury or death

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. Storage of or use of gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance can result in serious injury or death.

Read and follow water heater warnings and instructions

Do not use or store flammable products such as gasoline, solvents, or adhesives in the same room or area near the water heater. If such flammables must be used, all gas burning appliances in the vicinity must be shut off and their pilot lights extinguished. Open the doors and windows for ventilation while flammable substances are in use.

If flammable liquids or vapors have spilled or leaked in the area of the water heater, leave the area immediately and call the fire department from a neighbor’s home. Do not attempt to clean the spill until all ignition sources have been extinguished.

WARNING

Fire or Explosion Hazard

•Read instruction manual before installing, using or servicing water heater.

•Improper use may result in fire or explosion.

•Maintain required clearances to combustibles.

Keep combustibles such as boxes, magazines, clothes, etc. away from the water heater area.

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 chimney or gas vent as practical. Consider the vent system piping and combus- tion 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 water heater.

•Do not locate the water heater near an air-moving device. The operation of air-moving devices such as exhaust fans, ventilation systems, clothes dryers, fireplaces, etc., can af- fect the proper operation of the water heater. Special atten- tion must be given to conditions these devices may create.

Flow reversal of flue gases may cause an increase of carbon monoxide inside of the dwelling (Figure 10).

•The water heater is to be located as close as possible to a 120VAC outlet. NOTE: all electrical wiring should be in accordance to the NEC and all local/state electrical codes (extension cord is not allowed).

NOTE: This 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)-current edition and the “National Electrical Code”, ANSI/NFPS 70 current edition.
