All installations must be vented in accordance with National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the furnaces must be vented in accordance with the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments.NOTE: The vertical height of the Category I venting system must be at least as great as the horizontal length of theventing system.2.Line voltage wiring can enter through the right or left sideof the furnace. Low voltage wiring can enter through the right or left side of furnace.3.Conversion kits for high altitude natural or propane gasoperation are available. See High Altitude Derate chart for details.4.Installer must supply the following gas line fittings, de-pending on which entrance is used:Left -- Two 90º Elbows, one close nipple, straight pipe.Right -- Straight pipe to reach gas valve.General OperationGME8 furnaces are equipped with an electronic ignition de-vice used to light the burners and an induced draft blower to exhaust combustion products.An interlock switch prevents furnace operation if the blower door is not in place. Keep the blower access door in place except for inspection and maintenance.This furnace is also equipped with a self-diagnosing elec-tronic control module. In the event a furnace component is not operating properly, the control module LED will flash on and off in a factory-programmed sequence, depending on the problem encountered. This light can be viewed through the observation window in the blower access door. Refer to the Troubleshooting Chart for further explanation of the LED codes and Abnormal Operation - Integrated Ignition Control section in the Service Instructions for an explanation of the possible problem.The rated heating capacity of the furnace should be greater than or equal to the total heat loss of the area to be heated.The total heat loss should be calculated by an approved method or in accordance with “ASHRAE Guide” or “Manual J-Load Calculations” published by the Air Conditioning Con-tractors of America.*Obtain from: American National Standards Institute 1430Broadway New York, NY 10018Location 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 in the Installation and Service Instructions. The length of the rod will depend on the application and clearance necessary.•When installed in a residential garage, the furnace must be positioned so the burners and ignition source are located not less than 18 inches (457 mm) above the floor and protected from physical damage by ve-hicles.Notes:1. Category I Venting is venting at a non-positive pressure.A furnace vented as Category I is considered a fan-as-sisted appliance and the vent system does not have to be “gas tight.”PRODUCT DESIGNAccessibility Clearances (Minimum)Unobstructed front clearanace of 24" for servicing is rec-ommended.Top clearance for horizontal confirguration - 1"** Single Wall Vent (SW) to be used only as a connector.Refer to venting tables outlined in the installation manual foradditional venting requirements.* 24" clearance for serviceability recommended.24" at front is required for servicing or cleaning.Note: In all cases accessibility clearance shall take prece-dence over clearances from the enclosure where accessibil-ity clearances are greater. All dimensions are given in inches.High Altitude DerateIMPORTANT NOTE: The furnace as shipped requires no change to run between 0 - 4500 feet. Do not attempt to increase the firing rate by changing orifices or increasing the manifold pressure below 4500 feet. This can cause poor combustion and equipment failure.High altitude installations above 4500 feet may require both a pressure switch and an orifice change. These changes are necessary to compensate for the natural reduction in the density of both the gas fuel and the combustion air at higher altitude.For installations above 4500 feet, please refer to your dis-tributor for required kit(s). Contact the distributor for a tabular listing of appropriate manufacturer’s kits for propane gas and/or high altitude installations. The indicated kits must be used to insure safe and proper furnace operation. All con-versions must be performed by a qualified installer, or ser-vice agency.5PRODUCT DIMENSIONS6GME8******AAll dimensions are in inches.7PRODUCT DESIGN*All installations above 7,000 ft. require a pressure switch change.For installations in Canada, the GME8 furnace is certified only to 4,500 ft.*Negative pressure readings are in inches of water column (*w.c.)GME8***A*PRODUCT DIMENSIONS 8GME8***B**All installations above 4,500 ft. require a pressure switch change.For installations in Canada, the GME8 furnace is certified only to 4,500 ft. *Negative pressure readings are in inches of water column (*w.c.)PRODUCT DESIGNCoil Matches:A large array of Amana® brand coils are available for use with the new GME8 furnaces, in either upflow or horizontal applications.

FMA-900 SERIESAir Velocity TransducersStandardRemote Probee-mail:**************For latest product manuals:User’sGuideShop online atIt is the policy of OMEGA Engineering, Inc. to comply with all worldwide safety and EMC/EMI regulations that apply. OMEGA is constantly pursuing certification of its products to the European New Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.The information contained in this document is believed to be correct, but OMEGA accepts no liability for any errors it contains, and reserves the right to alter specifications without notice.WARNING: These products are not designed for use in, and should not be used for, human applications.General DescriptionThe OMEGA ®FMA-900 air velocity mass flow transducer is ideal for economical monitoring of clean air flows in ducts and pipes, while producing very little permanent pressure drop in the flowstream The FMA-900 employs two rugged glass-coated RTD elements, protected by a 1⁄4" diameter 304SS tube with a“window” cut out. One RTD is the velocity sensor, while the other RTD provides ambient air temperature compensation. The velocity sensor is heated to maintain a constant (approximately 30°C) temperature differential above the ambient air temperature, as measured by the second RTD element. The cooling effect of the air flow experienced by the velocity sensor is measured and converted to an electrical output signal proportional to air velocity. The FMA-900 is provided with a 13" long probe as standard. The 304SS tubing is provided with inch marks for ease of insertion depth.UnpackingThe following items are supplied with the FMA-900:•FMA-900 Series Air Velocity Transducer •Mating connector•Removable plastic protective cover (supplied on the sensor tip)•Operator’s manual1-1Important Considerations Before Installationintrinsically safe. Do not use for flammable or hazardous gases, or inhazardous areas.The FMA-900 air velocity transducer is intended for use with clean air or !nitrogen ONLY. Do not use with other gases, as other gases will produce anuncalibrated, non-linear output signal. In addition, air carrying dust or oil (suchas found in blower/compressor systems that utilize oil) can lead to coating of thesensor and thus, inaccurate readings. Refer to the Maintenance section for moreinformation on cleaning the sensor.The FMA-900 is a bi-directional device; flow in the forward or reverse directionprovides the same output.Installing the FlowmeterThe FMA-900 air velocity transducer can be mounted vertically or horizontallywithout shift in calibration.1.Remove the plastic protective cap from the sensor tip.2.Run a length of straight pipe before and after the flowmeter. The amount ofupstream straight pipe run required depends upon the type of obstruction whichis immediately upstream of the flow sensor. See Table 2-1 for specificrequirements. Downstream of the flow sensor, in all situations, run 5 diametersof straight pipe, regardless of the downstream obstruction.3.Align the FMA-900 with the air flow. Make sure the width of the electronics box(2 inches) is parallel with the flow stream.The score line on the tubing is another way of aligning the air flow sensor withthe flow stream. The score line starts from the center of the transducer windowand as a result it can be aligned properly.One means of installing the probe into a flow stream is to utilize a compressionfitting, such as OMEGA’s SSLK-14-14 stainless steel compression fitting withTeflon ferrules, which permits adjustment of the insertion depth of the probe.On Remote Probe Models (-R), connect the remote probe cable to the ElectronicHousing.1-2Table 2-1 Piping Requirements1-3Wiring the Flowmeter1.Connect pins as follows:PLUG PIN NO.DESCRIPTION1 0-5 Vdc or 4-20 mA Output (−)2 0-5 Vdc or 4-20 mA Output (+)3Power Supply (+)4No Connection5No Connection6Power Supply (−)2.Blow clean air through the FMA-900.3.Install the sensor into the pipe or duct.Measuring Air FlowThe FMA-900 measures standard velocity, which is the mass velocity of the airreferenced to 25°C and 760 mm Hg. No temperature or pressure corrections arerequired. Where SCFM (standard cubic feet per minute) measurements aredesired:1.Locate the point of average velocity in the pipe or duct.2.In round pipes, under turbulent flow conditions (where the Reynolds number isgreater than 5,000), mount the velocity sensor approximately 1⁄8of a pipediameter in from the the pipe wall. For example, in an 8" diameter pipe, mountthe probe 1" in from the pipe wall.3.For pipes or ducts where the flow is not turbulent, or the flow profile is notsymmetrical (due to inadequate straight pipe runs, etc.), perform a traverse ofthe duct, in accordance with standard duct traversal methods as recommendedby ASHRAE or the National Air Balance Council.4.To obtain SCFM, once the probe is mounted in the location of average velocity,multiply the average velocity readings (in SFPM, standard feet per minute) bythe cross-sectional area of the pipe or duct, in square feet. For standard pipe,these values can be found in the technical section of the OMEGA CompleteFlow and Level Measurement Handbook and Encyclopedia®. MaintenanceExcept for intermittent removal of the sensor from the line for cleaning, there isno routine maintenance for the FMA-900. If the probe becomes coated with dust,blow the dust away with clean air. If the probe is coated with sticky material,clean it with a solvent which is compatible with epoxy, glass, and 304SS, andwhich will not leave a residue on the sensor. You may clean the sensor withwater or alcohol (Ethanol) and an artist’s brush.CalibrationEach FMA-900 is individually calibrated in a NIST-traceable wind tunnel. Forcalibration certification or calibrating to a new range, the unit must be returnedto OMEGA.
