Temperature Rise

NOTE: Furnace must be adjusted to obtain a temperature rise within the range specified on the unit nameplate. Failure to do so may cause erratic limit operation and may result in premature heat exchanger failure.

This furnace must be installed so that its electrical components are protected from water.

Installed in Combination with a Cooling Coil

When this furnace is used with cooling units, it shall be installed in parallel with, or on the upstream side of, cooling units to avoid condensation in the heating compartment. See Figure 2. With a parallel flow arrangement, a damper (or other means to control the flow of air) must adequately prevent chilled air from entering the furnace. If the damper is manually operated, it must be equipped to prevent operation of either the heating or the cooling unit, unless it is in the full HEAT or COOL setting. See Figure 2.

When installed, this furnace must be electrically grounded according to local codes. In addition, in the United States, installation must conform with the current National Electric Code, ANSI/NFPA No. 70. The National Electric Code (ANSI/ NFPA No. 70) is available from the following address:

National Fire Protection Association 1 Battery March Park

Quincy, MA 02269

NOTE: This furnace is designed for a minimum continuous return air temperature of 60° F (16°C) or an intermittent operation down to 55° F (13°C) dry bulb for cases where a night setback thermostat is used. Return air temperature must not exceed 85° F (29°C) dry bulb.

This furnace may be installed in alcoves, closets, attics, basements, garages, and utility rooms in the upflow or horizontal position.

This furnace design has not been certified for installation in mobile homes, recreational vehicles, or outdoors.

Use of Furnace as a Construction Heater

Allied Air does not recommended the use of these units as a construction heater during any phase of construction. Very low return air temperature, harmful vapors and operation of the unit with clogged or misplaced filters will damage the unit.

Units may be used for heating of buildings or structures under construction, if the following conditions are met:

The vent system must be permanently installed per these installation instructions.

A room thermostat must control the furnace. The use of fixed jumpers that will provide continuous heating is not allowed.

The return air duct must be provided and sealed to the furnace.

Return air temperature range between 60°F (16°C) and 80°F (27°C) must be maintained.

Air filters must be installed in the system and must be maintained during construction.

Air filters must be replaced upon construction completion.

The input rate and temperature rise must be set per the furnace rating plate.

One hundred percent (100%) outdoor air must be provided for combustion air requirements during construc-tion. Temporary ducting may supply outdoor air to the furnace. Do not connect duct directly to the furnace. Size the temporary duct following these instructions in section for Combustion, Dilution and Ventilation Air in a confined space with air from outside.

The furnace heat exchanger, components, duct system, air filters and evaporator coils must be thoroughly cleaned following final construction clean-up.

All furnace operating conditions (including ignition, input rate, temperature rise and venting) must be verified according to these installation instructions.

Allied Air Enterprises 80G1UH2V, A80UH2V Temperature Rise, Installed in Combination with a Cooling Coil

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.
