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.

# Seconds Per Revolution

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 provided in Table 12. Typical manifold set point for installations at altitudes from 0 to 4500 feet above sea level is 10.0" W.C.

Temperature Rise

Check the temperature rise and, if necessary, adjust blower speed to maintain temperature rise within the range shown on the unit rating plate.

High Altitude

In both the United States and Canada, this furnace 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 12. To adjust the manifold pressure, refer to previous section Checking and Adjusting Gas Input. For installations above 7500 feet, call Technical Service at 1-800-515-3501 for assistance.

For installations above 4500 feet fill in the appropiate information on the furnace label that has the words “This furnace was converted on . . . . . . “.

Emergency Replacement Motor Operation

If the variable speed motor needs to be replaced in an emergency situation (such as “no heat”) and an exact replacement motor is not immediately available, a standard PSC motor of equivalent frame size, voltage, rotation, and horsepower can be temporarily installed until the correct replacement motor can be obtained.

Connect the desired speed tap to the “EAC” terminal and the neutral tap to the neutral terminal on the ignition control (refer to the furnace wiring diagram). T he ignition control will control the motor’s operation, including a nominal 20 second “on” delay with a call for heat and a nominal 180 second “off” delay when the thermostat is satisfied. It will also operate the motor on a call for cooling, with no “on” or “off” delays.

Verify that the unit is operating at the desired speed and within the rise range as shown on the unit rating plate.

The correct replacement motor must be installed as soon as possible to ensure continued satisfactory operation of the furnace.

MANIFOLD PRESSURE SETTINGS

*Consult local utility for actual heating value. Furnace input = Input Factor x Nameplate Input

NOTE: A natural to LP/Propane gas changeover kit is necessary to convert this unit. Refer to the changeover kit installation instruction for the conversion procedure.

80G1UH2V, A80UH2V specifications

Allied Air Enterprises has made a significant mark in the HVAC industry with its innovative and high-performance heating and cooling solutions. Among its impressive lineup, the Allied Air Enterprises 80G1UH2V and A80UH2V models stand out for their efficiency, reliability, and advanced features.

The 80G1UH2V is a two-stage gas furnace that operates on natural gas or propane. With an efficiency rating of up to 80%, it provides excellent heating performance while contributing to cost savings on utility bills. Its durable cabinet design ensures long-lasting performance and protection from harsh weather conditions, making it ideal for a variety of home environments.

One of the key features of the 80G1UH2V is its two-stage heating capability. This technology allows the furnace to operate at a lower capacity to maintain consistent temperatures during milder weather, reducing energy consumption and noise. When the temperature drops significantly, the furnace automatically shifts to high capacity, delivering the required heat promptly. This flexibility not only creates a more comfortable living space but also enhances energy efficiency.

The A80UH2V model shares similar traits with the 80G1UH2V but offers some additional features. It includes a variable-speed blower motor that optimizes airflow throughout the home. This innovation not only increases comfort levels but also facilitates quieter operation. The A80UH2V's advanced control system provides precise temperature management and can be integrated easily with smart home systems for enhanced automation.

Both models are designed to operate quietly, with noise levels minimized through improved insulation and sound-dampening technologies. This makes them suitable for residential applications, where comfort and peace are a priority. Additionally, they come equipped with a self-diagnostic control board that makes troubleshooting and maintenance simpler and more efficient.

Durability is another critical characteristic of both the 80G1UH2V and A80UH2V. They feature a robust heat exchanger made from high-quality materials, enhancing longevity and reliability. With these models, homeowners can expect reliable performance for years with minimal upkeep.

In summary, the Allied Air Enterprises 80G1UH2V and A80UH2V models deliver exceptional heating solutions through advanced technology, efficiency, and reliability. Their innovative features cater to the modern homeowner's need for comfort, control, and energy savings, making them excellent choices for residential heating needs.
