Amana VR8205 installation instructions Safety and Unit Location, Additional Safety Considerations

I. Safety and Unit Location

WARNING

To prevent personal injury or death due to improper installation, adjustment, alteration, service, or, maintenance refer to this manual or for additional assistance or information consult a qualified installer, service agency or the gas supplier.

WARNING

This product contains or produces a chemical or chemicals which may cause serious illness or death and which are known to the State of California to cause cancer, birth defects or other reproductive harm.

WARNING

To prevent possible death, personal injury or equipment damage due to fire, the following points must be observed when installing the unit.

WARNING

To prevent possible death, personal injury or property damage due to electrical shock, the furnace must be located to protect the electrical components from water.

NOTE: This unit must not be used as a “construction heater” during the finishing phases of construction on a new structure. This type of use may result in premature failure of the unit due to extremely low return air tempera- tures and exposure to corrosive or very dirty atmospheres.

WARNING

To prevent possible death, personal injury or property damage, do not install this unit in a mobile home, trailer or recreational vehicle.

ADDITIONAL SAFETY CONSIDERATIONS

•This furnace is approved for Category I Venting only.

•When the furnace is heating, the temperature of the return air entering the furnace must be between 55°F and 100°F.

•Do not install the furnace where the combustion air is exposed to the following substances: permanent wave solutions, chlorinated waxes or cleaners, chlorine based swimming pool chemicals, water softening chemicals, deicing salts or chemicals, carbon tetra- chloride, halogen type refrigerants, cleaning solutions (such as perchloroethylene), printing inks, paint re- movers, varnishes, hydrochloric acid, cements and glues, antistatic fabric softeners for clothes dryers,

and masonry acid washing materials. If the furnace is installed near an area which will be frequently con- taminated by these substances, the furnace should be sealed from this area so that little contaminated air can reach the furnace. The furnace must still have an adequate supply of combustion air, either from a nearby uncontaminated room or from outdoors. For details, see “AIR REQUIREMENTS” Section III.

•Provisions must be made for venting combustion products outdoors through a proper venting system. The length of flue pipe could be a limiting factor in locating the furnace.

•When installed horizontally, the furnace must be in- stalled with the access doors vertical so that the burners fire horizontally into the heat exchanger. The unit cannot be installed with the access doors on top or bottom. (See Specification Sheet)

•Allow clearances from the enclosure as shown on Specification Sheet for fire protection, proper opera- tion, and service access. These clearances must be permanently maintained. The combustion and venti- lating air openings in the front and top panels of the furnace must never be obstructed.

•This furnace shall not be connected to a chimney flue serving a separate appliance designed to burn solid fuel.

•When the furnace is used in connection with a cooling unit, the furnace must be upstream of, or in parallel with, the cooling unit. For details see Section VIlI.

•On Counterflow Installations, the air conditioning coil must be downstream from the heat exchanger of the furnace.

•Counterflow Installation over a noncombustible floor. Before setting the furnace over the plenum opening, insure the surface around the opening is smooth and level. A tight seal should be made between the furnace base and floor by using a silicone rubber caulking compound or cement grout.

•Counterflow Installation over a combustible floor. If installation over a combustible floor becomes neces- sary, use an accessory subbase as shown on the Specification Sheet. Follow the instructions with the subbase for proper installation. Do not install the furnace directly on carpeting, tile, or other combustible material other than wood flooring. (Note: The subbase will not be required if an air conditioning coil is installed between the supply air opening on the furnace and the floor.)

•The furnace must be level. If the furnace is to be set on a floor that may become wet or damp at times, the furnace should be supported above the floor on a concrete base sized approximately 1-1/2" larger than the base of the furnace.

ADDITIONAL LOCATION CONSIDERATIONS

•The furnace should be as centralized as is practical with respect to the air distribution system.

•Do not install the furnace directly on carpeting, tile, or combustible material other than wood flooring.

•When suspending the furnace from rafters or joists, use 3/8" threaded rod and 2” x 2” x 3/8” angle as shown on the Specification Sheet. The length of the rod will depend on the application and clearance necessary.
