They are not marked on the actual vent extension. 3 Figure 3. , , Remove the 5/16" screw used to mount the vent pipe assembly to the mounting bracket. Keep this screw. Five holes have been drilled into the vent extension (see Figure 4). Four of those holes are provided so that the vent can be extended the necessary length required for the installation. The wall sleeve that is installed determines which of these clearance holes should be used. Using Table 2 and Figure 4, determine which clearance hole should be used to position the vent extension properly. Slide the vent extension outward and line up the correct clearance hole on the vent extension with the hole in the vent pipe and the hole in the mounting bracket. Re-install the 5/16" screw that was removed in Step 3. Thread the screw first through the clearance hole in the mounting bracket, the proper clearance hole in the vent extension, and into the engagement hole in the vent pipe. The length of the vent pipe extension that Page 6 4 extends out of the cabinet should be as shown in Table 2. Installing and Securing Unit to Wall Sleeve Before installing and securing the unit to the wall sleeve, make sure that the proper louver kit is installed. Due the high temperatures of the combustion products released from the gas vent, MGE gas package units require the use of either an aluminum louver kit or special MGE polypropylene louver kit (see ACCESSORIES on page 17). 1. , Make sure the gaskets attached to the sleeve are not damaged. Verify divider panel is positioned properly. Figure 5 shows the correct position for 60" and 64" tall units (flange pointing up). For 58" tall units, the divider panel should be positioned so the flange points down. #46977A006 Positioning Divider sleeve, lower unit into position. This prevents damage to the base pads. Assure that unit is level and completely seated against the gaskets on the wall sleeve. Panel . Divider must be positioned this way (flange up) for 60" and 64" tall units. Use the two installation brackets to secure the unit to the wall sleeve (see Figure 6). The units are shipped with the brackets placed loose on the unit top panel, beneath packaging. Hook each bracket into the front edge of the wall sleeve side. Position the bracket so it can be bent around the front corner of the unit. Remove one of the two screws in that position on the unit. Line up one of the holes in the installation bracket with the screw hole and attach the bracket to the unit with that screw. Make sure to fasten tight enough that the seal is maintained. Trim off excess bracket if applicable. Inspect the fit up of the unit to the wall sleeve. Verify that the gaskets of the wall sleeve make a complete seal to the unit paying particular attention to top and bottom corners of unit to sleeve seal. Caulk if needed. Divider must be positioned this way (flange down) for 58" tall units.

Condensate Drain Installation Air Filter All indoor return air must be filtered. A washable filter is furnished with the unit, located in the return air opening. If return duct is installed, provisions must be made to accommodate filter servicing. The filter should be cleaned at least three times during each of the heating and cooling seasons, or more frequently if unusual conditions are encountered. To clean the washable filter, shake filter to remove excess dirt and/or use a vacuum cleaner. Wash filter in soap or detergent water and replace after filter is dry. It is not necessary to oil the filter after washing. If an installation is made in which it is more desirable to mount the filter exterior to the unit, in the return duct work or elsewhere, the washable filter can be used or replaced with a disposable filter. If a disposable filter is used, use the information provided in Table 4 when sizing the disposable filter. Figure 7 Electrical Connections Minimum Required for Disposable MGE*12 480 Square inches to 208 volt terminal as shown on the wiring diagram. 288 MGE*24 MGE 384 square inches All wiring must be done in accordance with the National Electrical Code (NEC), ANSI/NFPA No. 70 (latest edition); Canadian Electrical Code CSA C22.2 Part 1 (latest edition); or local codes, where they prevail. Any alteration of internal wiring will void certification and warranty. Units are factory wired for a 230 volt power supply. If power supply is 208 volts, it will be necessary to change a wire connection on unit transformer from 240 volt terminal 192 square inches MGE*18 . 30 Surface Area Filters I square inches 10 and 12 SEER models Table 4 Condensate Use wiring with a temperature limitation of 75°C minimum.

Drain Provisions must be made to properly drain the indoor and outdoor drain pans of this appliance. The indoor drain pan drains internally into the outdoor drain. The outdoor drain connection is a 3/4" NPT to 3/4" PVC fitting (schedule 40). The drain must be trapped as shown in Figure 7. The drain line should pitch gradually downward at least 1" per 10' of horizontal run to open drain. The unit must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code ANSI/NFPA No. 70 (latest edition) or CSA C22.2 Part 1 (latest edition). Power supply to the unit must be NEC Class 1 and must comply with all applicable codes. A fused disconnect switch should be field provided for the unit. The switch must be separate from all other circuits. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram. Electrical wiring must be sized to minimum circuit ampacity marked on the unit. Use copper conductors only. Each unit must be wired with a separate branch circuit and be properly fused. #46977A006 Page9 Gas Supply and Piping If local codes allow the use of a flexible gas appliance connector, always use a new listed connector. Do not use a connector which has previously serviced another gas appliance. Refer to unit rating plate to make sure the furnace is equipped to burn the gas supplied (natural or propane). Pipe connections must be tight, and a non-hardening pipe compound resistant to liquefied petroleum gases should be used. Connect the gas pipe to the furnace controls providing a ground joint union as close to the controls as is possible to facilitate removal of controls and manifold. Provide a drip leg on the outside of the furnace. A manual shutoff valve shall be installed in the gas line, outside the unit, 5' above the floor, or in accordance with any local codes. A test gauge connection must be installed with a 1/8" NPT plugged tapping immediately upstream of the shutoff valve (refer to Figure 8). Gas supply piping should be installed in accordance with local codes and the regulations of the utility. Piping must be of adequate size to prevent undue pressure drop. Consult the local utility or gas supplier for complete details on special requirements for sizing gas piping. Gas Supply Return The furnace must be isolated from the gas supply piping system by closing the individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig (3.5 kPa) or 14" W.C.

Turn the thermostat to lowest setting. 3. Turn the gas valve knob to the "ON" position (see Figure 9). 4. Turn on electrical power to the unit. 5. Set the room thermostat to the desired temperature. If the thermostat "set" temperature is above room temperature after the pre-purge time expires, burners will light. Gas Valve HONEYWELL GAS INLET /J GAS CONTROL KNOB Figure Page12 9 #46977A006 OPERATION "OFF" and turn off the electrical power supply and the gas supply to the unit. Operation of the unit is automatic and will provide heating and cooling depending on the setting of the thermostat. Adjustments - Heating Heating Temperature Rise 1. Turn on main power supply. At time of installation, the temperature rise must be adjusted to be within the range specified on the unit rating plate. 2. Open manual gas shutoff valve. 3. Set thermostat system to "HEAT". 4. Set thermostat to temperature desired. Checking Sequence of Operation 1. Thermostat calls for heat. 2. Combustion blower starts and proper air flow is proven by the pressure switch closing. 3. Blower continues to operate for 30 seconds prior to the burners lighting. 4. Ignition control begins spark and opens gas valve. The burners are lit. Ignition is proved through flame sensor. 5. Circulating air blower starts 30 seconds after the burners light. 6. When the thermostat is satisfied, the burners and combustion blower shut off. 7. Circulating air blower will shut off 120 seconds later. If the burners should fail to ignite, the ignition control will try to ignite the burners a total of three times. Should the burners fail to ignite within the three trials for ignition, the ignition control will lock out for 1 hour before beginning another ignition cycle. To reset the control, turn the thermostat down or off for 10 seconds and then set to desired setting. At this time, the ignition sequence will try again. Cooling 1. 2. Set thermostat system switch to "COOL". Set thermostat to temperature desired. NOTE: When Y is energized, the combustion blower will operate for 10 seconds. The purpose of this action is to deter insect nesting in the flue pipe. To Shut Down Unit For temporary or short periods of shutdown, set the thermostat system switch to "OFF". For a prolonged period of shutdown, set the thermostat system switch to #46977A006 Section and Adjusting Gas input The gas input must not exceed the figures shown on the rating plate. The unit is equipped for rated inputs with manifold pressures of: 3.5" W.C. for natural gas and 10.0" W.C. for propane. The furnace requires conversion for use with propane (a propane conversion kit is available from the manufacturer). The manifold pressure can be measured by removing the pipe plug in the downstream side of the gas valve and connecting a water manometer or gauge. Only small variations in gas input may be made by adjusting the regulator. In no case should the final manifold pressure vary more than 0.3" W.C. for natural gas or 0.7" W.C. for propane. To adjust the regulator, turn the adjusting screw on the regulator clockwise to increase pressure and input or counterclockwise to decrease pressure and input. For Natural Gas: Check the furnace rate by observing the gas meter, when available, making sure all other gas appliances are turned off. The test hand on the meter should be timed for at least one revolution. Note the number of seconds for one revolution. BTU/HR = Cubic Feet Per Revolution iNPUT # Seconds Per Revolution × 3600 × Heating Value The heating value of the gas can be obtained from the local utility company. For Propane Gas: The only check for the furnace rate is to properly adjust the manifold pressure using a manometer and the information found in Table 5 on page 14. Typical manifold set point for installations at altitudes from 0 to 4500' above sea level is 10.0" W.C. Adjustments - Cooling Section No adjustments are required or should be attempted regarding any of the components of the cooling system.

Table 6 Fan Control Furnace Input = Input Factor x Nameplate Input Above 7500 feet, call Technical Services at 1-800448-5872 ext. 2610. Table 5 The system should be checked to see that none of the wiring is loose or missing. System Performance For maximum performance of the cooling system, the operating temperatures and pressures should be checked and superheat determined at Standard ARI test conditions of 82°F outdoor- 80°F indoor dry bulb/67°F wet bulb. If superheat measured deviates from the values given in Table 6, refrigerant charge should be adjusted accordingly for maximum performance. The blower will start approximately 30 seconds after the burners ignite and will stop approximately 120 seconds after the thermostat is satisfied. The time delay is preset at the factory and timing cannot be adjusted. When the thermostat system switch is set for "COOL", the blower will start 5 seconds after the thermostat calls for cooling and will stop 90 seconds after the thermostat is satisfied. A fan switch is provided on the thermostat which will bring the blower on for continuous operation when the switch is set for "ON". Limit Control A fixed temperature limit control is provided which will shut off the gas to the burners if the unit is overheated for any reason. The control must not be adjusted or relocated. Blower Rollout Switch The unit contains a direct-drive, multispeed blower. The proper speeds have been preset at the factory for heating and cooling. Refer to the wiring diagram for recommended heating/cooling speeds for specific models. Direct-drive blower motors are permanently lubricated and do not require oiling. If for any reason the exchanger were to become blocked, there is a temperature sensitive switch located above the burners that will turn off the burners. After correcting the problem, this switch must be manually reset by pressing the button on top of it. High Altitude Blower Operation Continuous operation of the air handling blower will be obtained if the thermostat fan switch is set to "ON". With the thermostat fan switch set to "AUTO", the air handling blower will cycle corresponding with the thermostat cycling. Page14 In both the United States and Canada, this unit is approved for operation at altitudes from 0 to 4500 feet above sea level without any required modifications. From 4500 to 7500 feet, the gas manifold pressure needs to be adjusted according to the information shown in Table 5. To adjust the #46977A006 manifoldpressure, refertoprevioussectionChecking and Adjusting Gas Input on page 13. For installations above 7500 feet, call Technical Service at 1-800-448-5872 ext. 2610 for assistance. Installation and Operation Weather Areas in Extremely Cold In areas where extremely cold outdoor temperatures (below - 20°F) can be expected, some additional installation and operating precautions should be taken. The following precautions are designed to prevent possible vent system ice blockage that could result in safety shutdown of the burners: , Adjust to the highest achievable temperature rise within the rise and static pressure ranges specified on the rating plate. Depending on specific model, it may be possible to change to a lower heating blower speed tap to get a higher temperature rise. This also increases comfort. 2. Make sure there are no leaks of outside air into the return air system. 3. Keep the outside louver grille as free as possible of any ice that may form and obstruct the flue outlet. #46977A006 Page15 MAINTENANCE Cooling System The refrigeration system normally requires no maintenance since it is a closed, self-contained system. Periodic maintenance is limited to: Cleaning the air filter. Follow directions noted on the filter and label attached to the access panel. Cleaning the condenser coil if covered with any foreign material, lint, leaves, or other obstructions. Burners The burners can be removed for cleaning or changing orifices. To remove the burners: 1. Disconnect electrical service and turn off gas to the appliance. 2. Disconnect the high voltage (spark plug) wire and the flame sensor wire (Sl) from the ignition control. 3. Remove spark and sense rods. 4. Remove the four screws that mount the burner right side plate (houses the spark/sense probes). 5. Carefully remove the burner right side plate. 6. Burners are now exposed and can be individually removed from assembly by removing the two screws that hold each burner in the burner rack. Burners can be cleaned using a bottle brush. Orifices are threaded into the gas manifold and can be removed by unscrewing. When replacing the burner tray assembly, take care in installing the sense and spark rods back into the burner plate. Reconnect the spark and sense wires. Heat Exchanger The heat exchanger should be inspected periodically and cleaned if necessary.
