55. Choosing Installation Site* Locate the appliance in an area where leakage from the unit or connections will not result in damageto the area adjacent to the appliance or to the lower floors of the structure. When such locationscannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installedunder the appliance. The pan must not restrict combustion air flow.• Install the exhaust vent so that there are no obstacles around the termination and so thatexhaust can't accumulate. Do not enclose the termination with corrugated metal or othermaterials.• Avoid places where fires are common, such as those where gasoline,benzene and adhesives are handled, or places in which corrosive gases(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.Using the incorrect voltage may result in fire or cracking.• Avoid installation in places where dust or debris will accumulate.Dust may block the air-supply opening, causing the performance of thedevice fan to drop and incomplete combustion to occur as a result.• Avoid installation in places where special chemical agents(e.g., hair spray or spray detergent) are used.Ignition failures and malfunction may occur as a result.• Carbon Monoxide Poisoning Hazard. Do not install this water heater in amobile home, recreation vehicle or on a boat.• Install the water heater in a location where it is free from obstacles and stagnant air.• Consult with the customer concerning the location of installation.• Do not install the water heater near staircases or emergency exits.• Do not install the water heater where the exhaust will blow on outer walls or material not resistantto heat. Also consider the surrounding trees and animals.The heat and moisture from the water heater may cause discoloration of walls and resinousmaterials, or corrosion of aluminum materials.• Do not locate the vent termination directed towards a window or any other structure which hasglass or wired glass facing the termination.ProhibitedDANGERWARNINGCAUTION
