SECTION I: FURNACE DESCRIPTION

This furnace is a modulating furnace. It is designed to maximize the

comfort in the home and to minimize the sound level in the home by

varying (modulating) the gas input and the circulating airflow to closely

match the amount of heating needed at any given time.

SECTION II: SAFETY

This is a safety alert symbol. When you see this symbol on

labels or in manuals, be alert to the potential for personal

injury.

Understand and pay particular attention to the signal words DANGER,

WARNING, or CAUTION.

DANGER indicates an imminently hazardous situation, which, if not

avoided, will result in death or serious injury

WARNING indicates a potentially hazardous situation, which, if not

avoided, could result in death or serious injury

CAUTION indicates a potentially hazardous situation, which, if not

avoided may result in minor or moderate injury.

It is also used to

alert against unsafe practices and hazards involving only property dam-

age.

Improper installation may create a condition where the operation of

the product could cause personal injury or property damage.

Improper installation, adjustment, alteration, service or mainte-

nance can cause injury or property damage. Refer to this manual

for assistance or for additional information, consult a qualified con-

tractor, installer or service agency.

This product must be installed in strict compliance with the installa-

tion instructions and any applicable local, state, and national codes

including, but not limited to building, electrical, and mechanical

codes.

92306-UIM-A-0108 SPECIFIC SAFETY RULES AND PRECAUTIONS 1. Only Natural gas or Propane (LP) gas are approved for use with this furnace. Refer to the furnace rating plate or Section V of these instructions. Install this furnace only in a location and position as specified below. A gas-fired furnace for installation in a residential garage must be installed as specified in Section II of these instructions.
PAGE 3
292306-UIM-A-0108 INSPECTION The furnace area must not be used as a broom closet or for any other storage purposes, as a fire hazard may be created. Never store items such as the following on, near, or in contact with the furnace. 1. Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners or other cleaning tools. 2. Soap powders, bleaches, waxes or other cleaning compounds; plastic items or containers; gasoline, kerosene, cigarette lighter fluid, dry cleaning fluids or other volatile fluid. 3.
PAGE 4
292306-UIM-A-0108 Installation in a residential garage: A gas-fired furnace for installation in a residential garage must be installed so the burner(s) and the ignition source are located not less than 18 inches (46 cm) above the floor, and the furnace must be located or protected to avoid physical damage by vehicles.
PAGE 5
292306-UIM-A-0108 Example: The furnace input is 80,000 BTUH, 1,200 CFM blower requirement. The recommended duct area is 216 sq.in, there are two 8 x 12 rectangular ducts attached to the plenum and there are two 7 inch round ducts attached to the furnace. 1. 2. Take 8 x 12, which equals 96 square inch x 2 = 192 square inches then go to round duct size located in Table 3. The square inch area for 7 inch round ducts, 38.4 square inch x 2 = 76.8 square inches, 3.

292306-UIM-A-0108 MANUAL SHUT-OFF VALVE DRIP LEG GAS PIPE The gas valve body is a very thin casting that can take any limited external force. Never apply a pipe wrench to the body of the gas valve when installing piping. A wrench must be placed on the octagonal hub located on the gas inlet side of the valve. Placing a wrench to the body of the gas valve will damage the valve causing improper operation and/or the valve to leak.

292306-UIM-A-0108 ELECTRICAL POWER CONNECTIONS All models use nominal 115 VAC, 1 Phase, 60-Hertz power supply. DO NOT CONNECT THIS APPLIANCE TO A 50 HZ POWER SUPPLY OR A VOLTAGE ABOVE 130 VOLTS. Field wiring to the unit must be grounded. Electric wires that are field installed shall conform to the temperature limitation of 63°F (35°C) rise when installed in accordance with these instructions. Refer to Table 5 in these instructions for specific furnace electrical data.

292306-UIM-A-0108 CONDENSATE DRAIN TERMINATION DO NOT terminate condensate drain in a chimney, or where the drain line may freeze. The line must terminate at an inside drain to prevent freezing of the condensate and possible property damage. DO NOT trap the drain line at any other location than at the condensate drain trap supplied with the furnace. A condensate sump pump MUST be used if required by local codes, or if no indoor floor drain is available.

292306-UIM-A-0108 TOOLS AND INFORMATION THAT WILL BE REQUIRED IN ORDER TO PROPERLY PERFORM THE FURNACE STARTUP PROCEDURE. 1. Call the local gas supplier to obtain heating value of the natural gas. If you cannot obtain the heating valve of the gas from the gas supplier, you may use a default value of 1030 BTU/SCF (38.8 MJ / m³). 2. You will need a thermometer or portable digital thermometer to read the supply and return air temperatures. 3.

292306-UIM-A-0108 In the USA use the following formula to calculate the furnace input. For natural gas multiply the heat content of the gas BTU/SCF or Default 1030 BTU/SCF (38.4 MJ/m3), times 2 cubic ft. (0.056 m) of gas measured at the gas meter, times a barometric pressure and temperature correction factor of 0.960; times 3600, then divided by the time (In seconds) it took to measure 2 cubic ft. (0.056 m) of gas from the gas meter.

Refer to Figure 39 for location of pressure regulator adjustment cap and adjustment screws on main gas valve. Turn gas and electrical supplies on and follow the operating instructions to place the unit back in operation.

292306-UIM-A-0108 Tap C is the dry profile. This profile is best suited to parts of the country where excessive humidity is not generally a problem, where the summer months are usually dry. On a call for cooling the motor will ramp up to full capacity and will stay there until the thermostat is satisfied. At the end of the cooling cycle, the blower will ramp down to 50% of full capacity where it will stay for 60 seconds. Then it will ramp down to zero.

292306-UIM-A-0108 Seven Red Flashes - Lockout due to no ignition. The control will try three times for ignition. If flame cannot be established in three tries, the control will lockout for one hour and then will try again to light. Check gas supply, ignitor, gas valve, flame sensor. Eight Red Flashes - Lockout due to too many flame recycles. This flash code occurs if flame is lost five times during a single heating cycle. This could be caused by a faulty gas valve, low gas pressure, or dirty flame sensor.

292306-UIM-A-0108 FILTER PERFORMANCE The airflow capacity data published in Table 17 represents blower performance WITHOUT filters. To determine the approximate blower performance of the system, apply the filter drop value for the filter being used or select an appropriate value from the Table 18. NOTE: The filter pressure drop values in Table 18 are typical values for the type of filter listed and should only be used as a guideline.
