Location RequirementsWARNINGCarbon Monoxide Poisoning HazardDo 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 offlammable vapor-related fires. The patented systemprotects your family by trapping the burning vaporswithin the water heater combustion chamber through thespecial flame-arrestor. The burning vapors literally “burnthemselves out” without escaping back into the room.In the event of a flammable vapor incident, the FVIRSystem disables the water heater by shutting off the gassupply to the water heater’s burner and pilot, preventingre-ignition of any remaining flammable vapors in the area.This will not prevent a possible fire/explosion if the igniteris depressed and flammable vapors have accumulatedin the combustion chamber with the pilot light off. If yoususpect a flammable vapor incident has occurred, do notuse this appliance. Do not attempt to light this appliance,or depress the igniter button if you suspect flammablevapors have accumulated inside or outside the appliance.Immediately call a qualified technician to inspect theappliance. Water heaters subjected to a flammable vaporsincident will show a discoloration on the flame-arrestor andrequire replacement of the entire water heater.FLAMMABLESWARNINGFlammable VaporsFIRE AND EXPLOSION HAZARDCan result in serious injury or deathDo not store or use gasoline or other flammablevapors and liquids in the vicinity of this or any otherappliance. Storage of or use of gasoline or otherflammable vapors or liquids in the vicinity of this orany other appliance can result in serious injury ordeath.Read and follow water heater warnings andinstructionsDo not use or store flammable products such as gasoline,solvents, or adhesives in the same room or area near thewater heater. If such flammables must be used, all gasburning appliances in the vicinity must be shut off and theirpilot lights extinguished. Open the doors and windows forventilation while flammable substances are in use.If flammable liquids or vapors have spilled or leaked inthe area of the water heater, leave the area immediatelyand call the fire department from a neighbor’s home. Donot attempt to clean the spill until all ignition sources havebeen extinguished.WARNINGFire or Explosion Hazard• Read instruction manual before installing, using orservicing water heater.• Improper use may result in fire or explosion.• Maintain required clearances to combustibles.Keep combustibles such as boxes, magazines, clothes, etc. awayfrom the water heater area.Site Location• Select a location near the center of the water pipingsystem. The water heater must be installed indoorsand in a vertical position on a level surface. DO NOTinstall in bathrooms, bedrooms, or any occupied roomnormally kept closed.• Locate the water heater as close to the chimney or gasvent as practical. Consider the vent system piping andcombustion air supply requirements when selecting thewater heater location. The venting system must be ableto run from the water heater to termination with minimallength and elbows.• Locate the water heater near the existing gas piping.If installing a new gas line, locate the water heater tominimize the pipe length and elbows.• The water heater should be located in an area notsubject to freezing temperatures. Water heaterslocated in unconditioned spaces (i.e., attics,basements, etc.) may require insulation of the waterpiping and drain piping to protect against freezing.The drain and controls must be easily accessible foroperation and service. Maintain proper clearances asspecified on the rating plate.• Do not locate the water heater near an air-movingdevice. The operation of air-moving devices suchas exhaust fans, ventilation systems, clothes dryers,fireplaces, etc., can affect the proper operation of thewater heater. Special attention must be given to conditionsthese devices may create.
