RT6612002 Revision 1 September 2000 PRODUCT IDENTIFICATION The model and manufacturing number are used for positive identification of component parts used in manufacturing. When engineering and manufacturing changes take place where interchangeability of components are affected, the manufacturing number will change. It is very important to use the model and manufacturing numbers at all times when requesting service or parts information.

THIS MAY CAUSE SERIOUS INJURY OR DEATH. AMANA WILL NOT BE RESPONSIBLE FOR ANY INJURY OR PROPERTY DAMAGE ARISING FROM IMPROPER SERVICE OR SERVICE PROCEDURES. IF YOU PERFORM SERVICE ON YOUR OWN PRODUCT, YOU ASSUME RESPONSIBILITY FOR ANY PERSONAL INJURY OR PROPERTY DAMAGE WHICH MAY RESULT. CAUTION 2 Rev. 1 PRODUCT DESIGN General Operation This GUVA furnace is equipped with an electronic ignition device 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 doors in place except for inspection and maintenance. This furnace is also equipped with a self-diagnosing electronic 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. 3. Conversion kits for propane gas and high altitude natural and propane gas operation are available. See High Altitude Derate chart for details. 4. Installer must supply the following gas line fittings, depending on which entrance is used: Left -- Two 90° Elbows, one close nipple, straight pipe Right -- Straight pipe to reach gas valve. Accessibility Clearances (Minimum) MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS POSITION* Upflow Horizontal SIDES 0 6 (INCHES) FRONT REAR 3 0 3 0 TOP 1 6 BOTTOM C C FLUE 0 0 * = All positioning is determined as installed unit is viewed from the front. C = If placed on combustible floor, floor MUST be wood ONLY. 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 Contractors of America. 36" at front is required for servicing or cleaning. *Obtain from: American National Standards Institute 1430 Broadway New York, NY 10018 High Altitude Derate When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be installed. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range. 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 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 vehicles. Notes: 1. Installer must supply one or two PVC pipes: one for combustion air (optional) and one for the flue outlet (required). Vent pipe must be either 2” or 3” in diameter, depending upon furnace input, number of elbows, length of run and installation (1 or 2 pipes). The optional Combustion Air Pipe is dependent on installation/code requirements and must be 2” or 3” diameter PVC. Note: In all cases accessibility clearance shall take precedence over clearances from the enclosure where accessibility clearances are greater. All dimensions are given in inches.

Optional kits are available for conversion to propane gas operation. 2. For elevations above 2000 feet the rating should be reduced by 4% for each 1000 feet above sea level. The furnace must not be derated, orifice changes should only be made if necessary for altitude. 3. The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufacturers method in accordance with the "A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CONDITIONING CONTRACTORS OF AMERICA. The total heat loss calculated should be equal to or less than the heating capacity. Output based on D.O.E. test procedures, steady state efficiency times output. 4. Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps. 8 Rev. 1 BLOWER PERFORMANCE SPECIFICATIONS GUVA045AX30 (Rise Range: 30 - 60°F) Heating Speed Tap Adjust Tap Minus (-) A B C D Low Stage High Stage CFM CFM at at .1" to .5" w.c. .1" to .5" w.c.
