CAUTION

HUD Manufactured Home Construction and Safety

Standards (3280.714) prohibit the use of noncertiﬁed

air conditioning or heat pump equipment with

this furnace. It is strongly recommended that

manufactured housing air conditioning components

from Nortek Global HVAC be selected to provide

a matched system speciﬁcally designed to meet

these requirements.

The cutting, splicing or modifying of any internal

electrical wiring may void product warranties and

create a hazardous condition. Failure to comply

with these standards could also provide inadequate

heating or cooling performance and cause structural

damage to a manufactured home.

Please contact your local distributor for help. A

directory of Nortek Global HVAC factory authorized

servicers is located in the furnace homeowner

packet.

special requirements for incorporation of air conditioning equipment to the MG1 furnaces. Unit Location • The furnace shall be appropriately located to the supply and return air distribution system (page 5). Sides and back of the furnace may be enclosed by wall framing. See Minimum Clearances section on page 4. • The furnace installation is only intended for free air return through the furnace door louvers. DO NOT connect a ducted return air system directly to the furnace.
PAGE 6
• Means shall be provided that prevent inadvertent closure of flat objects placed over the return air opening located in the floor of the closet (versus the vertical front or side wall). • The total free area of openings in the floor or ceiling registers serving the return air duct system must be at least 235 in2.

IMPORTANT NOTE: Refer to the wiring diagram inside the control box cover or Figure 31 (page 25) for the wiring of your particular unit. Any other wiring methods must be acceptable to authority having jurisdiction. CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. IMPORTANT NOTE: Proper line voltage polarity must be maintained in order for the control system to operate correctly.
PAGE 14
Low Voltage Wiring • The furnace is designed to be controlled by a 24 VAC thermostat. The thermostat’s wiring must comply with the current provisions of the NEC (ANSI/NFPA 70) and with applicable local codes having jurisdiction. • The thermostat must be installed according to the instructions supplied by the thermostat manufacturer. Low voltage connections (24 VAC) from the thermostat are wired to the terminal strip on the integrated control in the furnace.
PAGE 15
This furnace may be installed with left, right, or bottom gas entry. When connecting the gas supply, provide clearance between the gas supply line and the entry hole in the furnace casing to avoid unwanted noise and/or damage to the furnace. Typical gas service hookup for this furnace is shown in Figure 26. Table 9, (page 23) lists gas flow capacities for standard pipe sizes as a function of length in typical applications based on nominal pressure drop in the line.

Code or local jurisdiction. In Canada, the requirements for high altitude are different and governed by CSA B149.1. Always consult your local code authority. This furnace is shipped from the factory with orifices and gas regulator settings for natural gas operation at sea level altitudes. At 2,000 feet, the NFGC requires that this appliance be derated 4% for each 1000 feet of altitude. For example, the input needs to be reduced 8% at 2,000 feet, 12% at 3,000 feet and etc.

9. Reconnect the gas piping and electrical wires to the gas valve. 10.Open the manual shut-off valve and follow the Operating Instructions on page 19. Measuring the Supply Gas Pressure To obtain an accurate pressure reading, turn off all gas appliances (i.e. Dryers, water heaters, stoves, etc.) at their ON/OFF control or individual gas valves. 1. Remove the inlet pressure plug from the INLET side of the gas valve with a 3/16 Allen wrench. See Figure 27. 2.
PAGE 19
WARNING: Before placing the furnace in service, it must be checked to ensure it is equipped for the type of gas being used. The burner flame must be observed and adjusted if necessary. Failure to observe this caution may result in unsafe operation, explosion and/or fire, or asphyxiation. See the Gas Supply and Combustion Air sections. • The first operation of the furnace after any home setup must be performed by a qualified service technician.

OPERATING SEQUENCE Direct Ignition Furnaces GAS CONTROL KNOB Figure 28. Direct Ignition Gas Valve - Honeywell readings, the thermometer on the supply air side must be shielded from direct radiation from the heat exchanger. 2. Adjust all registers and duct dampers to the desired position and run the furnace for 10 to 15 minutes in high fire before taking any temperature readings. The temperature rise is the difference between the supply and return air temperatures.
