4.If you touch ungrounded objects (recharge your body with static electricity), firmly touch furnace again before touch- ing control or wires.
5.Use this procedure for installed and uninstalled (un- grounded) furnaces.
6.Before removing a new control from its container, dis- charge your body's electrostatic charge to ground to protect the control from damage. If the control is to be installed in a furnace, follow items 1 through 5 before bringing the control or yourself into contact with the furnace. Put all used AND new controls into containers before touching ungrounded objects.
7.An ESD service kit (available from commercial sources) may also be used to prevent ESD damage.
INTRODUCTION
→The Model 395CAV, Series G Furnace is available in sizes 45,000 through 155,000 Btuh input capacities.
The design of the upflow
Before installing the furnace, refer to the current edition of the NFGC. Canadian installations must be installed in accordance with NSCNGPIC and all authorities having jurisdiction. For further information, the NFGC is available from National Fire Protection Association Inc., Batterymarch Park, Quincy, MA 02269; Ameri- can Gas Association, 1515 Wilson Boulevard, Arlington, VA 22209; or from Literature Distribution.
Installation must conform to the regulations of the serving gas supplier and the local building, heating, and plumbing codes in effect in the area in which the installation is made, or in the absence of local codes with the requirements of the NFGC.
CAUTION: Application of this furnace should be in- doors with special attention given to vent sizing and material, gas input rate, air temperature rise, and unit sizing. Improper installation or misapplication of the furnace can require excessive servicing or cause prema- ture component failure.
This furnace is designed for a minimum continuous
WARNING: Improper installation, adjustment, alter- ation, service, maintenance, or use can cause carbon monoxide poisoning, explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, local gas supplier, or your distributor or branch for information or assistance. The qualified installer or agency must use only
For accessory installation details, refer to the applicable instruction literature.
NOTE: Remove all shipping brackets and materials before operating the furnace.
I.LOCATION
A. General
CAUTION: Do not install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating air requirements are met, in addition to all local codes and ordinances.
→CAUTION: Do not use this furnace during construction when adhesives, sealers, and/or new carpets are being installed. If the furnace is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine when burned with
combustion air form acids which cause corrosion of the heat exchangers and metal vent system. Some of these compounds are found in paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction pro- cess.
Excessive exposure to contaminated combustion air will result in safety and performance related problems.
This furnace must be installed so the electrical components are protected from water. This furnace shall not be installed directly on carpeting, tile, or any combustible material other than wood flooring.
Locate furnace as close to the chimney/vent and as near the center of the air distribution system as possible. The furnace should be installed as level as possible.
When a furnace is installed so that the supply ducts carry air to areas outside the space containing the furnace, the return air must also be handled by a duct(s) sealed to the furnace casing and terminating outside the space containing the furnace.
Provide ample space for servicing and cleaning. Always comply with the minimum fire protection clearances shown on the unit rating plate.
B.Location Relative to Cooling Equipment
The cooling coil must be installed parallel with or on the downstream side of the unit to avoid condensation in the heat exchangers. When installed parallel with a furnace, dampers or other means used to control the flow of air must prevent chilled air from entering the unit. If the dampers are manually operated, they must be equipped with means to prevent operation of either unit unless the damper is in the
C.Hazardous Locations
When the furnace is installed in a residential garage, it must be installed so that the burners and ignition source are located at least 18 in. above the floor. The furnace should be protected from physical damage by vehicles. When a furnace is installed in public garages, airplane hangars, or other buildings having hazardous atmospheres, the unit must be installed in accordance with the recommended good practice requirements of the National Fire Protection Association, Inc.
II.AIR FOR COMBUSTION AND VENTILATION
Provisions for adequate combustion and ventilation air must be provided in accordance with Section 5.3 of the NFGC, Air for Combustion and Ventilation, or applicable provisions of the local building codes.
Canadian installations must be installed in accordance with NSC- NGPIC and all authorities having jurisdiction.
