Removal of the Furnace from Common Vent

In the event that an existing furnace is removed from a venting system commonly run with separate gas appliances, the venting system is likely to be too large to properly vent the remaining attached appliances.

Conduct the following test while each appliance is operating and the other appliances (which are not operating) remain connected to the common venting system. If the venting system has been installed improperly, you must correct the system as indicated in the general venting requirements section.

WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death.

The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation:

1.Seal any unused openings in the common venting system.

2.Inspect the venting system for proper size and horizontal pitch. Determine that there is no blockage, restriction, leakage, corrosion, or other deficiencies which could cause an unsafe condition.

3.Close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

4.Follow the lighting instructions. Turn on the appliance that is being inspected. Adjust the thermostat so that the appliance operates continuously.

5.After the burners have operated for 5 minutes, test for leaks of flue gases at the draft hood relief opening. Use the flame of a match or candle.

6.After determining that each appliance connected to the common venting system is venting properly, (step 3) return all doors, widows, exhaust fans, fireplace dampers, and any other gas burning appliances to their previous mode of operation.

7.If a venting problem is found during any of the preceding tests, the common venting system must be modified to correct the problem.

Resize the common venting system to the minimum vent pipe size determined by using the appropriate tables in Appendix G. (These are in the current standards of the National Fuel Gas Code ANSI 2223.1.

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.
