Resumen del manual
Place the appliance being inspected into operation. Adjust the thermostat so appliance is operating continuously. 7. Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle. 8. If improper venting is observed during any of the above tests, the venting system must be corrected in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Codes. 9. After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas-fired burning appliance to their previous conditions of use. ELECTRICAL CONNECTIONS When installed, the furnace must be electrically grounded in accordance with local codes or, in the absence of local codes, with the (U.S.) National Electrical Codes, ANSI/NFPA 70 or CSA Standard C22.1; Part 1 Canadian Electrical Code. For proper installation refer to furnace rating label for electrical ratings and for the field wiring of this unit refer to furnace wiring specifications on page 5 or alternately from the wiring diagram on page 27. In all instances, other than wiring for the thermostat, the wiring to be done and any replacement of wire shall conform with the temperature limitation for Type T wire [63°F rise (35°C)]. The electrical connections and the thermostat connections are made at the openings on either side panel of the unit in the control box area. Either side may be used as convenient, but the provided hole plugs must be inserted in the unused holes. The control system depends on the correct polarity of the power supply. Connect "Hot" (H) wire and "Ground" (G) wire as shown in furnace wiring specification on wiring diagram. Use reference Table on page 3 (Furnace Specifications), for over current protection, max unit amp rating and wire size. Use copper wire only for 115Vsupply service to unit. When replacing any original internal wiring, use only 105°C, 16 AWG copper wire. Thermostat: Instructions for wiring the thermostat are packed in the thermostat (field supplied) box. Make the thermostat connections as shown in furnace wiring specifications at the 24-volt terminal board located in the control box. Single Stage Thermostat Operation: The automatic heat staging option allows a single stage thermostat to be used with a two stage furnace. To activate this option, move the jumper pin (see Figure 11) to desired setting (5 minutes or 10 minutes). The furnace will start on first (1ST) stage heat and stay at first (1ST) stage heat for the duration of the selected time before switching to 2nd stage heat. 20571201 Issue 0527 Page 15 of 28 Figure 11 AUTOMATIC HEAT STAGING JUMPER When installing optional accessories to this appliance, follow the manufacturer's installation instructions included with the accessory. The unit cabinet must have an uninterrupted or unbroken electrical ground to minimize personal injury if an electrical fault should occur. This may consist of electrical wire or approved conduit when installed in accordance with existing electrical codes. Do not use gas piping as an electrical ground. Failure to follow this warning can result in an electrical shock, fire, bodily harm, or loss of life. GAS CONNECTIONS Gas piping shall be of such size and so installed as to provide a supply of gas sufficient to meet maximum demands without undue loss of pressure between the gas meter and the furnace. It is recommended that the gas line to the furnace shall be a separate line direct from the meter, unless the existing gas line is of ample capacity. Refer to gas pipe capacity table in the National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes. If local codes allow the use of a flexible gas appliance connector, always use a new listed connector. Do no use a connector which has previously serviced another gas appliance. Use a joint compound (pipe dope) that is resistant to the action of liquefied petroleum gases or any other chemical constituents of the gases to be conducted through the piping. For proper furnace operation the maximum gas supply pressure is 14" w.c. and the minimum gas supply pressure is 4.5" w.c. - Natural (11" w.c. - LP) as shown on rating label. Before any system of gas piping is finally put into service, it should be carefully tested to determine if it is gas tight. Check all piping for leaks using soapy water and a brush. The piping must stand a pressure of six (6) inches of mercury (3 PSIG) for a period of ten (10) minutes or as required by local authority. FIRE OR EXPLOSION HAZARD Failure to follow the safety warnings exactly could result in serious injury, death or property damage. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connec...
