6.The entire length of single wall metal vent connector shall be readily accessible for inspection, cleaning, and replacement.

7.Single appliance venting configurations with zero lateral lengths (Tables 3 and 4) are assumed to have no elbows in the vent system. For all other vent configurations, the vent system is assumed to have two 90° elbows. For each additional 90° elbow or equivalent (for example two 45° elbows equal one 90° elbow) beyond two, the maximum capacity listed in the venting table should be reduced by 10% (0.90 x maximum listed capacity).

8.The common venting Tables (5, 6,7, and 8) were generated using a maximum horizontal vent connector length of 1-1/2 feet (.46 m) for each inch (25 mm) of connector diameter as follows:

Table 2

9.If the common vertical vent is offset, the maximum common vent capacity listed in the common venting tables should be reduced by 20%, the equivalent of two 90° elbows (0.80 x maximum common vent capacity). The horizontal length of the offset shall not exceed 1-1/2 feet (.46 m) for each inch (25 mm) of common vent diameter.

10.The vent pipe should be as short as possible with the least number of elbows and angles required to complete the job. Route the vent connector to the vent using the shortest possible route.

11.A vent connector shall be supported without any dips or sags and shall slope a minimum of 1/4 inch (6.4 mm) per linear foot (305 mm) of connector, back toward the appliance.

12.Vent connectors shall be firmly attached to the furnace flue collar by self drilling screws or other approved means,except vent connectors of listed type B vent material which shall be assembled according to the manufacturer’s instructions. Joints between sections of single wall connector piping shall be fastened by screws or other approved means.

13.When the vent connector used for Category I appliances must be located in or pass through a crawl space, attic or other areas which may be cold, that portion of the vent connector shall be constructed of listed doublewall type B vent material or material having equivalent insulation qualities.

14.All venting pipe passing through floors, walls, and ceilings must be installed with the listed clearance to combustible materials and be fire stopped according to local codes. In absence of local codes, refer to NFGC (2223.1 ).

15.No portion of the venting system can extend into, or pass through any circulation air duct or plenum.

16.Vent connectors serving Category I appliances shall not be connected to any portion of mechanical draft systems operating under positive pressure such as Category III or IV venting systems.

17.If vent connectors are combined prior to entering the common vent, the maximum common vent capacity listed in the common venting tables must be reduced by 10%, the equivalent of one 90° elbow (0.90 x maximum common vent capacity).

18.The common vent diameter must always be at least as large as the largest vent connector diameter.

19.In no case, shall the vent connector be sized more than two consecutive table size diameters over the size of the draft hood outlet or flue collar outlet.

20.Do not install a manual damper, barometric draft regulator or flue restrictor between the furnace and the chimney.

21.When connecting this appliance to an existing dedicated or common venting system, you must inspect the venting system’s general condition and look for signs of corrosion. The existing vent pipe size must conform to these instructions and the provided venting tables. If the existing venting system does not meet these requirements, it must be resized.

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.
